Always look down and behind before and whilebacking up.Never push forward suddenly on your control leverswhile the machine is in rearward motion becausemachine may tip backwards.Never pull back suddenly on your control levers whilethe machine is in forward motion.When moving in reverse, push forward slowly on controllevers and avoid sudden movement. Rapid movement ofthe control levers in either direction could result in areaction of the mower that can cause serious injury.Never operate a poorly maintained machine.Never attempt high speed maneuvering, especially incrowded or congested areas.Never allow persons to operate this machine withoutproper instruction or allow children to operate machine.Allow only responsible adults who are familiar withthese instructions to operate this machine.Never put hands or feet under any part of the machinewhile it is running.Never carry passengers.Never direct discharged material toward anyone. Avoiddischarging material against a wall or obstruction. Mate-rial may ricochet back towards the operator. Always dis-engage the blades and wait for them to stop beforecrossing gravel drives, walks or roads.Always keep clear of the mower blades and attachmentsduring their operation.Turn off blades when not mowing.Slow down before turning.Stop the engine before removing the grass catcher orunclogging the discharge chute. Never clear the dischargechute with the engine running. Turn off the engine and besure the blades have stopped before cleaning. Use a stickto clear a plugged discharge area. Never use your hand!Always keep clear of the mower blades and attachmentsduring operation.Do not operate the machine if you are fatigued, sick orwhile under the influence of alcohol or drugs, if your arepregnant or under 18 years old.Exercise caution when loading or unloading the machineonto a trailer or truck.Always wear safety goggles or safety glasses with sideshields when operating the mower.Data indicates that operators, age 60 years and above, areinvolved in a large percentage of riding mower-relatedinjuries. These operators should evaluate their ability tooperate the mower safely enough to protect themselvesand others from serious injury.Follow the manufacturer’s recommendation for wheelweights or counterweights.If any attachment or additional weight is mounted on therear of the unit, any rapid movement of the control levers

3-2 601656_0410

in either direction could result in a reaction of the mowerthat can cause serious injury.Clean flammable material from machine. Preventfires by keeping engine compartment, top of deck,exhaust area, battery, fuel line, fuel tank and opera-tor’s station clean of accumulated trash, grass clip-pings, and other debris. Always clean up spilled fueland oil.Always secure the ROPS in the raised position andbuckle seat belt before starting mower.

Using a rampUse extreme caution when loading and unloading a unitonto a truck or trailer with a ramp.Use only a single, full width ramp; do not use individualramps for each side of the unit. Having a full width rampprovides a surface for the mower frame to contact if theunit starts to tip backwards. It also reduces the risk of awheel going off and the machine tipping over.Do not exceed a 15 degree angle between the ramp andthe ground or between the ramp and the trailer or truck.When on a ramp avoid sudden acceleration

Slope OperationSlopes are a major factor in loss-of-control and tip-overaccidents, which can result in severe injury or death. Allslopes require extra caution. If you cannot back up the slopeor if you feel uneasy on it; do not mow it. REMINDER: Onlyoperate on slopes of 15 degrees or less.

Use extreme caution when operating on slopes.• Be extremely careful changing directions on a slope.

Slow down.• Do not operate where the machine could slip or tip.• Turn slowly• Turn on the most level part of the slope• To maximize traction, it is better to turn the front of the

machine uphill, rather than downhill. If drive tires losetraction, steering control is lost which could causeserious injury or death.

• If it becomes necessary to turn downhill, turn slowlyand gradually, if possible.

Do not remove or modify the stabilizer wheels.Watch for holes, ruts, bumps, rocks or other hiddenobjects. Uneven terrain could overturn the machine. Tallgrass can hide obstacles.Remove obstacles such as rocks, tree limbs, etc.Keep all movement on slopes slow and gradual. Do notmake sudden changes in speed or direction.Avoid starting and stopping on a slope. If tires lose trac-tion, disengage the blades and proceed slowly straightdown the slope.Mow a safe distance (minimum of 10 feet) away fromdrop-offs, retaining walls, drainage ditches, embank-ments, water, and other types of hazards to avoid a wheeldropping over the edge or to avoid the ground frombreaking away. This will reduce the risk of the machinesuddenly rolling over causing serious injury or death.Use a walk behind, push mower or hand-held trimmer onslopes and near drop-offs, retaining walls, drainage

ditches, embankments and water to avoid machine roll-over and serious injury or death.Do not mow on wet grass. Slippery conditions reducetraction which could cause sliding and loss of control.Do not tow on slopes. The weight of the towed equip-ment may cause loss of traction and loss of control.Do not try to stabilize the machine by putting your footon the ground.If the mower’s tires lose traction when operating onslopes, disengage the blades, place the control levers inthe park brake position, turn the engine off and get help.Never make sudden starts, stops, turns, or reverse direc-tion, especially when maneuvering on slopes. The steer-ing is designed for sensitive response. Rapid movementof the control levers in either direction could result in areaction of the mower that can cause serious injury.Never stop suddenly while backing down slopes. Thisaction may result in a reaction of the mower that cancause serious physical injury.The Hustler mower is capable of operating horizontally(traverse) on moderately steep slopes. When operating onslopes up to 15 degrees, be aware of any conditions thatmay cause the mower drive tires to lose traction resultingin a possible loss of control of the machine. An operatorshould not operate on a slope until he is thoroughlyfamiliar with the equipment.Do not operate on slopes greater than 15 degrees.IMPORTANT: The Hustler ATZ only, is capable ofoperating on slopes of 15 degrees or more (maximum 25degrees). Do not operate the Hustler ATZ on slopesgreater than 25 degrees.Refer to the Slope Guide, page 2-9, when determining thedegree of slope to be mowed.It is strongly recommended that the operator drive themachine off of the slope, using extreme caution, if anysign of loss of traction is detected. Wait until the condi-tion that caused the problem is resolved before attempt-ing to operate on the slope again.Terrain conditions can affect traction resulting in possibleloss of control of the machine. Some of the conditions tobe aware of are:1. Wet terrain2. Depressions in the ground; i.e. holes, ruts, washouts3. Mounds of dirt4. Soil type; i.e. sand, loose dirt, gravel, clay5. Grass type, density, and height6. Extremely dry conditions of grass7. Tire pressureThe attachments mounted to the mower will also affectthe way it handles on a slope. Be aware that each attach-ment’s characteristics vary.Do not tow on slopes. The weight of the towed equip-ment may cause loss of traction and loss of steering con-trol.Another consideration to safe mowing on slopes is to beaware of what is located at the bottom of the slope.Extreme caution should be used when there is a hazardlocated at the bottom of the slope. Some examples are:1. Water; i.e. lake, river2. Cliffs, retaining walls

601656_0410 3-3

3. Roads, highways4. Buildings5. RocksThese are just a few examples of situations when cautionmust be used when operating on a slope. There are manyother possibilities too numerous to mention. Just remem-ber to always exercise extreme caution when operatingon any slope.The ROPS will minimize chance of injury or death fromrollover. Seat belt must be fastened while operating amachine equipped with ROPS in the raised and securedposition. Both retaining pins and hair pins must beinstalled. Failure to use seat belt will result in seriousinjury in the event of a roll over.

ChildrenTragic accidents can occur if the operator is not alert to

the presence of children. Children are often attracted to themachine and the mowing activity. Never assume thatchildren will remain where you last saw them.

Never leave machine unattended with ignition key inswitch, especially with children present.

Children or bystanders may be injured if they move orattempt to operate the mower while it is unattended.Always disengage deck clutch, place control levers inpark brake position, stop the engine, and remove ignitionkey when leaving operator’s seat.Keep children out of the mowing area and under thewatchful care of a responsible adult other than the opera-tor.Be alert and turn the machine off if children enter thearea.Before and while backing, look behind and down forsmall children.Never carry children, even with the blades off. They mayfall off and be seriously injured or interfere with safemachine operation. Children who have been given ridesin the past may suddenly appear in the mowing area foranother ride and be run over or backed over by themachine.Never allow children to operate the machine.Never allow children or others in or on towed equipment.Use care when approaching blind corners, shrubs, trees,the end of a fence or other objects that may obscurevision.

the right fuel tank and the lower gauge indicates the fuellevel in the left fuel tank.

ControlsA. Control levers (Figure 3-3 & Figure 3-4) — these

levers control the mower’s speed, direction, stopping,and park brake. Levers are used to steer, accelerate,decelerate and change direction. When the control leversare in the park brake position (3-3) the mower will notmove when the engine is on and drive pumps areoperating.

WARNING: The parking brake may not hold themower if parked on a slope. Block or chock themachine when parked on a slope.

B. Deck lift pedal (Figure 3-5) — the deck lift pedal is usedto raise or lower the deck. Push on the pedal to raise thedeck and then place the deck height locking pin into thedesired cutting height hole.Push the deck lift pedal to raise the deck when going overobstructions.

Safety start interlock systemThe mower is equipped with a safety start interlock system

consisting of the park brake switches, seat switch, and deckclutch switch.

Check the mower’s safety start interlock system daily,prior to operation. This system is an important mower safetyfeature. It should be repaired immediately if it malfunctions.The machine incorporates a separate seat switch which will stopthe engine when the operator is unseated for any reason whilethe mower is operating. This is a safety feature designed toprevent runaway or accidental entanglement. To inspect thesystem:

1. The operator must be on the seat when testing the seatswitch.

2. Set both control levers in the park brake position.

Figure 3-2

Throttle

3-6 601656_0410

3. Start the engine and allow it to warm up to operatingtemperature.

4. With the deck clutch switch down and the control leversin the park brake position, slowly raise off of the seat.The engine should continue to run.

5. With the deck clutch switch up and/or the control leversin the neutral position, slowly raise off of the seat. Theengine should stop.

6. If the engine fails to stop when the deck clutch switch isup or one or both of the control levers is up and theoperator is off the seat, check the function of the seatswitch. If the seat switch is not operating properly (is notopening or closing) and if the cause can not bedetermined, replace the seat switch.

If the problem can not be located, contact your Hustler Dealer.

WARNING: The safety interlock system shouldalways function per steps 4 and 5. If it does not func-tion properly, it should be corrected immediately. Donot operate machine without properly functioning seatsafety switch.

Engine (gasoline) startingThe mower’s safety start interlock system is also designed to

protect the operator and others from accidental injury due tounintentional engine starting. The engine starting motor will notengage until:

A. Control levers are in the park brake position.B. Deck clutch switch is in the down (OFF) position.

WARNING: The safety interlock system must not bedisconnected or bypassed. Doing so could cause themachine to operate unexpectedly resulting in personalinjury.

NOTE: The operator’s seat is equipped with a separatesafety switch. If for any reason the operator should becomeunseated when the control levers are not in the park brake posi-tion (park brake switches are disengaged) or the deck clutchswitch is engaged the engine will stop.

2. Make sure the control levers are in the park brakeposition and deck clutch switch is disengaged. Only startthe engine from the operator’s position.

3. Use choke, if unit is equipped with one, when engine iscold, or if warm engine fails to start within 5 seconds ofcranking. Avoid flooding and operate engine withoutchoking as soon as possible.

4. Set throttle at approximately 1/2 open position. 5. Insert key in ignition switch and rotate full clockwise to

engage starting motor. Release key when engine starts.IMPORTANT: The engine starter should not be operated

for periods longer than 30 seconds at a time. An interval of atleast two minutes should be allowed between such crankingperiods to protect the starter from overheating and burn-out.

6. Perform test to make sure safety start interlock system isoperating properly. Refer to Safety start interlock systemsection.

7. As soon as engine begins to run, check to make certainthe oil warning light, check engine light and alternatorwarning light (if applicable) are off. If not, stop engineimmediately and check for the cause.

8. Allow the engine to idle a few minutes before advancingthe throttle and/or engaging the deck clutch.

Engine (diesel) startingThe Hustler Z Shibaura Diesel safety start interlock system is

designed to protect the operator and others from accidentalinjury due to unintentional engine starting. The engine startingmotor will not engage until:

A. Control levers are in the park brake position.B. Deck clutch switch is in the down (OFF) position.

WARNING: The safety interlock system must not bedisconnected or bypassed. Doing so could cause themachine to operate unexpectedly resulting in personalinjury.

NOTE: The operator’s seat is equipped with a separatesafety switch. If for any reason the operator should becomeunseated when the brake switches are disengaged or the deckclutch switch is engaged the engine will stop.

The following steps are the correct procedures for starting theengine. If difficulty is encountered, contact the Hustler Dealer inyour area.

1. Before starting mower each day, perform daily pre-

operation checking.2. Make sure the control levers are in the park brake

position and deck clutch switch is disengaged. Only startthe engine from the operator’s position.

3. Set throttle at approximately 1/2 open position.4. Insert key in ignition switch and rotate it to the “PRE-

HEAT/RUN” position. It takes two seconds before theglo-plug light will come on. Wait for the glo-plug light togo off (approximately 6 seconds) before rotating the keyto the “START” position. This is necessary only when thetemperature is below 50°F (10°C). This operation is notnecessary when restarting a warm engine.Shown in the chart are the standard preheating times forvarious temperatures. This operation, however, is notrequired when the engine is warmed up.Failure to follow these recommendations can lead topremature failure of the starter motor and the fuelshut-off solenoid.NOTICE: Ether, or other starting fluids, must neverbe used as a starting aid with this engine. Warrantywill be denied when engine damage results from suchuse.

5. Rotate ignition switch key full clockwise to engagestarting motor. Release key when engine starts.

Stopping the engineUse the following procedure to shut off the engine after

operating the equipment.1. Place the control levers in the park brake position2. Disengage the deck clutch3. Throttle back to low idle for a couple of minutes4. Rotate ignition key counter-clockwise to the “OFF”

position. Remove the key from switch before leaving themower.

Moving mower with stalled engineIf it becomes necessary to move the mower when the engine

is inoperative, the hydraulic pumps are equipped with bypassvalves. Before moving the unit, turn bypass valves counterclockwise one-half to one revolution. The valve stems on eachhydraulic pump are located near the top and are identified as ahex stud. The valve is located per Figure 3-7, Figure 3-8 orFigure 3-9.

The steering control levers must be placed in the neutralposition, to release the park brakes, so that the mower can bemoved.

Do not tow the machine. Move it by hand or use a winch toload on a trailer for transporting.

ROPS(Roll Over Protective Structure)

A Roll Over Protective Structure (ROPS) and seat belt isprovided with the equipment. Do not remove the ROPS and seatbelt. ROPS when used with seat belt is effective in reducinginjuries during unit overturn accidents. Overturning the unitwithout ROPS can result in serious injury or death.

NOTE: Inspect the ROPS after the first 20 hours of opera-tion. Following the initial inspection, check the ROPS afterevery 500 hours of operation or every six months, whichevercomes first. Figure 3-10

1. Check the torque of the ROPS mounting bolts. Tighten

the bolts to the correct torques as shown below ifnecessary. Figure 3-11, Figure 3-12 or Figure 3-13

2. Inspect the operator’s seat and the mounting parts for theseat belt. Tighten the bolts to the correct torque as shownbelow if necessary and replace parts that show wear ordamage.

right and left retaining rings and pulling out on the clevis pins sothat the machine can operate under low hanging tree limbs orother obstructions. Do not wear the seat belt when the ROPS isin the lowered position. Use the ROPS in the “folded”position only when it is absolutely necessary. Figure 3-10

WARNING: Do not operate the mower with theROPS folded (lowered position) as a standard operat-ing mode. A folded ROPS does not provide rolloverprotection.

WARNING: Always wear your seat belt unless themower is not equipped with a ROPS or if the ROPS isfolded down. In this case, the seat belt should never beworn.

WARNING: To minimize chance of injury or deathfrom rollover: keep ROPS in the raised and lockedposition and use the seat belt.Never operate machine on a slope with the ROPSfolded down (lowered position).There is no roll over protection when the ROPS isin the lowered position.Lower the ROPS only when absolutely necessary.Drive slowly and carefully. Raise the ROPS as soonas clearance permits. Read and follow slope opera-tion instructions and warnings.Do not wear seat belt when the ROPS is in the low-ered position.

WARNING: Always pull from the mower hitch. Donot attach chains or ropes to the ROPS for pulling pur-poses, as the machine can tip backwards.

Always fasten seat belt during operation of the machine(mower equipped with ROPS in “raised/up” position).

Inspect the area to be mowed for proper overhead clearance(tree limbs, guy wires, doorways, etc)

Do not contact any overhead object with the ROPS.Inspect the seat belt system (all seat, seat belt parts, seat pan

and seat pan latch) daily prior to mowing for signs of anydamage. These parts should be replaced if any parts indicatesigns of:

1. cuts2. fraying3. extreme or unusual wear4. significant discoloration due to UV exposure5. dirt or stiffness6. abrasion to the seat belt webbing7. damage to the buckle, latch plate or hardware.8. or any other problem

If the seat belt is to be cleaned, use soap and water. Do not usecarbon tetrachloride, naphtha, etc., as these will weaken thewebbing. For the same reason, do not bleach or dye thewebbing. Replace seat belt if worn or damaged.

Possible damage to the ROPSIf the unit has rolled over or the ROPS has been in some other

type of accident (such as hitting an overhead object duringtransport), the ROPS must be replaced to retain the bestprotection.

Following an accident, check the ROPS, the operator’s seat,and the seat belt and seat belt mountings for possible damage,Before operating the machine, replace all damaged parts.

IMPORTANT: Do not attempt to weld or straighten theROPS.

WARNING: If the ROPS or cab is removed orreplaced, make sure that the proper hardware is usedand the recommended torque values are applied to theattaching bolts.

WARNING: The ROPS structure’s protectivecapability may be impaired by structural damage,overturn or alteration. Do not remove or alter any ofthe ROPS parts. Do not attempt to weld or straightenROPS. Failure to adhere to these instructions couldresult in severe injury or death.

Driving the mower

DANGER: Never make sudden stops or reversedirection, especially when maneuvering on a slope.The steering is designed for sensitive response. Rapidmovement of the control levers in either directioncould result in a reaction of the mower that can causeserious injury.

After starting engine, engage the control levers and steer asfollows:

To go forward, push control levers forward an equal distance(Figure 3-14).

To go in reverse, pull control levers rearward an equaldistance (Figure 3-14).

To turn left, move the right control lever farther forward fromneutral than the left control lever.(Figure 3-14)

To turn right, move the left control lever farther forward

from neutral than the right control lever. (Figure 3-14)“0” degree turn, move one control lever forward and the

other control lever back of neutral. This will allow the drivewheels to counter-rotate. (Figure 3-14)

To stop or decrease speed, move control levers to neutral.When going forward pull back gently on control levers. Whengoing in reverse push forward gently on control levers.

For emergency stop, when traveling forward or rearward,place the steering control levers in the park brake positionimmediately.

DANGER: When moving in the rearward directionpush forward gently on steering control levers andavoid sudden movement. Any sudden movementcould cause the front of the mower to come off of theground resulting in possible loss of control, causingserious injury or death.

To make a three point turn to the right, move the leftcontrol lever farther forward from neutral than the right controllever and start the turn. Next, pull back on the control leversuntil they are past neutral and the machine starts to go rearward.Pull right control lever farther rearward from neutral than theleft control lever until the rear of the machine has pivotedaround. Then, push the control levers forward until they are bothpast neutral and the machine starts to go forward. Push the leftcontrol lever farther forward from neutral than the right controllever and finish the turn. (Figure 3-15)

IMPORTANT: Rapid movement of control levers is not rec-ommended as damage to the hydraulic system components mayoccur.

To increase speed, increase control lever’s distance fromneutral. The farther forward control levers are from neutral, thefaster the mower will travel forward. The farther back controllevers are from neutral, the faster the mower will go in reverse.

Operating suggestions

DANGER: Prior to operating the mower the operatorshould be thoroughly familiar with the proper use andoperation of the equipment, should read the manualcompletely and thoroughly, and should have attemptedslow moving maneuvers to become familiar with theoperation of the equipment before attempting normalspeed operation. An inexperienced operator should notmow on slopes or on uneven terrain.

WARNING: If you lose steering control while oper-ating the machine, place the steering control leversin the park brake position immediately. Inspect themachine and involve your Hustler dealer to resolvethe problem before continuing to operate.

WARNING: The unit’s steering control levers arevery responsive: Easy does it! For smooth operation,move lever slowly, avoid sudden movement. Skill andease of operation come with practice and experience.The machine can spin very rapidly. Use caution whenmaking turns and slow down before making sharpturns.

601656_0410 3-11

Inexperienced operators may have a tendency to oversteer andlose control. Slow-moving practice maneuvers arerecommended to become familiar with these characteristicsbefore attempting normal speed operation.

WARNING: Sharp depressions or raised obstacles(such as gutters or curbs) should not be directlyapproached at high speed in an attempt to “jump”them as the operator could be thrown from the equip-ment. Approach at a slow speed and angle one drivewheel at the obstruction. Continue at an angle until thewheel clears and then pivot the opposite wheel around.

When turning on soft wet turf, keep both wheelsrolling either forward or backward. Pivoting on one stoppedwheel can damage turf. This is especially important whenmowing.

Tractor performance is maximum when the throttle is set atfull rpm. This gives maximum power to the drive wheels anddeck when needed. Use the control levers to control groundspeed rather than engine rpm.

Keep blades sharp. Many professional mowing companieshave additional sets of blades and change blades twice a day:once in the morning and again at noon. Many problems withincorrect cutting patterns are due to dull blades or blades whichhave been sharpened incorrectly. Information on sharpeningblades is listed in this manual’s maintenance section. Inaddition, most communities have individuals or companieswhich specialize in sharpening mower blades. Blade sharpnessshould be checked daily.

DANGER: Never work with blades while engine isrunning or deck clutch switch is engaged (on). Alwaysplace deck clutch switch in the disengaged position,place control levers in the park brake position and turnengine off and disconnect negative battery cable.Block up mower when you must work under it. Weargloves when handling blades. Always check forblade damage if mower strikes rock, branch or otherforeign object during mowing!

Use high blade speed. Your mower is designed to operate atfull throttle. The throttle setting directly controls blade speed.The highest blade speed generally gives best cut.

Direct grass discharge to right, away from unmown area.Select a mowing pattern that directs grass discharge towards theoutside, not towards center, of mowing area. Generally, thismeans using a pattern utilizing left turns because side dischargeis to right. In any case, avoid throwing grass discharge ontounmowed area because grass is then mowed “twice”. Mowingtwice puts an unnecessary load on the unit and reduces mowingefficiency.

When mowing a lawn for the first time cut grass slightlylonger than normal to avoid scalping uneven terrain. Whenpossible, it is best to use the cutting height that was used in thepast. When cutting grass taller than six inches, you may want tomow the lawn twice to achieve a better quality of cut.

During normal mowing cut only about 1/3 of the grassblade. Cutting more than that is not recommended unless grassis sparse or it is the end of the mowing season.

Alternate mowing direction to keep the grass growingstraight and better dispersion of the clippings.

Remember, grass grows at different rates at different timeof the year. Mow more often in the early spring to maintain thesame cutting height. As the growth rate slows in mid summer,mow less frequently. If you cannot mow at a regular interval,mow at a high cutting height; then mow again two days later at alower cutting height.

Raise the cutting height of the mower if the cutting width ofthe mower is wider than the previous mower. This ensures thatuneven turf is not cut too short.

Raise the cutting height of the mower if the grass if slightlytaller than normal or if it contains a high degree of moisture.Then mow it again with the cutting height set lower.

If the machine’s forward motion must be stopped whilemowing, a clump of grass clippings may drop onto your lawn.To avoid this, move onto a previously cut area with the bladesengaged.

Mower deck operation

DANGER: Never attempt to make any adjustments tothe mower deck while the engine is running or withthe deck drive clutch engaged. Mower blades cannotbe seen and are located very close to deck housing.Fingers and toes can be cut off instantly.

With the engine running, engage the deck clutch switch(Figure 3-1) and advance engine throttle to full rpm.

NOTE: Engaging the deck clutch at high engine rpm orwhen under heavy load (in tall grass for example) can causebelts and/or electric clutch to slip, resulting in premature wear orpossible damage.

Deck cutting height adjustmentDeck height is adjustable from 1” to 5” (2.54 cm - 12.7 cm) in

1/4” (.64 cm) increments. The holes in the height adjusting barare spaced at 1/2” (1.27 cm) intervals. By turning the heightadjusting stop around, 1/4” (.64 cm) increments can be attaineddue to the 1/4” (.64 cm) plate that is part of the stop. Figure 3-17

EXAMPLE: When the height adjusting stop is placed in the1” (2.54 cm) hole, with the 1/4” (.64 cm) plate facing to thefront of the unit, the cutting height is at 1”. When the heightadjusting stop is placed in the 1” (2.54 cm) hole, with the 1/4”(.64 cm) plate on the operator’s side of the hole, the cuttingheight is at 1-1/4” (3.18 cm).

The notch located at the rear of the height adjusting bar is tobe used when the deck is placed in the transport mode.

Anti-scalp wheelsAnti-scalp wheel kits are standard on Hustler Mid Mount Z

units. These anti-scalp wheels are designed to minimizescalping when mowing on rough uneven terrain.

wheels so they extend below the deck but do not contact theground. They should always be at least 1/4” to 3/4” (6.35mm to19.05mm) below the deck. With the unit sitting on a flat levelsurface, the front wheel position can be adjusted up or down asneeded from 3/4” to 1-3/4” (19.05mm to 44.45mm) below theblade surface. Move the front wheels up or down, in 1/2”(12.70mm) increments, using the different axle mount holes inthe wheel mount bracket. Figure 3-18

When adjusting the rear anti-scalp wheels, the wheel shouldbe in the lower axle mount hole when the front anti-scalp wheelsare in the lower or middle axle mount holes. When the frontwheels are in the upper axle mount hole, the rear wheels shouldbe in the upper axle mount hole as well.

NOTE: When the anti-scalp wheels are installed, the mini-mum cutting height is 1” (2.54 cm) with the anti-scalp wheelsset at 3/4” (1.91cm).

BAC-VAC™ MountingIf a BAC-VAC™ is to be mounted to an Hustler ATZ mower

it will be necessary to remove the following from the unit:1. Drive wheel weights

2. Frame weights located between the drive wheels3. The front and rear mount legs of the ROPS structure. The

two post ROPS structure will remain. Figure 3-19The weights included with the BAC-VAC™ will be used

instead of the Hustler ATZ mower weights.If a BAC-VAC™ is mounted to the Hustler ATZ it will be

necessary to remove the BAC-VAC™ and front wheel weightsfrom the mower and it will be necessary to re-attach the drivewheel weights, frame weights and the front and rear mount legsto the mower before operating the unit on a slope.

MAINTENANCE & ADJUSTMENTSSafe Servicing Practices

This product is capable of amputating hands and feet andthrowing objects. Always follow all safety instructions to avoidserious injury or death.

ServiceUnless specifically required, DO NOT have engine run-ning when servicing or making adjustments to mower.Park the machine on level ground. Place steering controllevers in the park brake position, disengage deck clutch,lower deck, remove ignition switch key and disconnectnegative battery cable before doing any maintenance.Wait for all movement to stop before adjusting, cleaningor repairing. Repairs or maintenance requiring enginepower should be performed by trained maintenance per-sonnel only. To prevent carbon monoxide poisoning, besure proper ventilation is available when engine must beoperated in an enclosed area. Read and observe safetywarnings in front of manual.Before working on or under the deck, make certainengine cannot be accidentally started. Shut engine off,remove ignition switch key and disconnect negative bat-tery cable for maximum safety. Repairs or maintenancerequiring engine power should be performed by trainedmaintenance personnel only.Except when changing or checking belt, always keep beltcovers on mower deck for safety as well as cleanliness.Use a stick or similar instrument to clean under themower making sure that no part of the body, especiallyarms and hands are under mower.Keep your machine clean and remove any deposits oftrash and clippings, which can cause engine fires andhydraulic overheating as well as excessive belt wear.Clean up oil or fuel spillage. Allow machine to coolbefore storing. Clean flammable material from machine. Preventfires by keeping engine compartment, top of deck,exhaust area, battery, hydraulic lines, fuel line, fueltank and operator’s station clean of accumulatedtrash, grass clippings, and other debris. Always cleanup spilled fuel and oil.Always wear adequate eye protection when servicing thehydraulic system and battery, or when grinding mowerblades and removing accumulated debris. Use extra caution when handling gasoline and otherfuels. They are flammable and vapors are explosive.Never attempt to start engine when there is a strong odorof gasoline fumes present. Locate and correct cause.Never remove the fuel cap or refuel mower while engineis running; never refuel near an open flame or neardevices which can create a spark. Refuel outdoors. Neverrefuel or drain the fuel from the machine indoors.Never run the engine in an enclosed area unless exhaustis vented to the outside. Exhaust gases contain carbonmonoxide which is odorless and deadly poison.Never attempt to make any adjustments or repairs to themower drive system, mower deck or any attachmentwhile the mower engine is running or deck clutch is

engaged. Repairs or maintenance requiring engine powershould be performed by trained maintenance personnelonly.Never work under the machine or attachment unless it issafely supported with jack stands. Make certain machineis secure when it is raised and placed on the jack stands.The jack stands should not allow the machine to movewhen the engine is running and the drive wheels arerotating. Use only certified jack stands. Use only appro-priate jack stands, with a minimum weight rating of 2000pounds to block the unit up. Use in pairs only. Follow theinstructions supplied with the vehicle stands.Do not touch hot parts of machine.Keep nuts and bolts tight, especially the blade attachmentbolts. Keep equipment in good working condition.Never tamper with safety devices. Check their properoperation regularly.Stop the engine before removing the grass catcher orunclogging the discharge chute. Never clear the dischargechute with the engine running. Turn off the engine and besure the blades have stopped before cleaning. Use a stickto clear a plugged discharge area. Never use your hand!Grass collection system components are subject to wear,damage and deterioration, which could expose movingparts or allow objects to be thrown. Frequently checkcomponents and replace with manufacturer’s recom-mended parts, when necessary.Exercise caution when working under the deck as themower blades are extremely sharp. Wrap the blade(s) orwear gloves and use extra caution when servicing them.Use only genuine Hustler replacement parts to ensure thatoriginal standards are maintained

IntroductionRegular maintenance is the best prevention for costly

downtime or expensive, premature repair. The following pagescontain suggested maintenance information and scheduleswhich the operator should follow on a routine basis. Thefollowing pages contain suggested maintenance information andschedules which the operator should follow on a routine basis.For more detailed information order the correct parts manual foryour unit. Refer to the Product Literature section of this manual.

Remain alert for unusual noises, they could be signaling aproblem. Visually inspect the machine for any abnormal wear ordamage. A good time to detect potential problems is whileperforming scheduled maintenance service. Correcting theproblem as quickly as possible is the best insurance.

Clear away heavy build-up of grease, oil and dirt, especiallyin the engine and under the seat platform areas; minute dustparticle are abrasive to close-tolerance engine and hydraulicassemblies.

Daily inspect mower for grass clippings and wire and stringtangles. The underside of the mower deck will collect a build-upof grass clippings and dirt, especially when grass is wet or hashigh moisture content. This build-up will harden, restrictingblade and air movement and will probably show a poorer qualityof cutting. Therefore it should be removed routinely.

To do this it will be necessary to raise and block the deck,

4-2 601656_0410

using jack stands or blocks, in the full up position and scrape thebuild-up from underneath.

Some repairs require the assistance of a trained servicemechanic and should not be attempted by unskilled personnel.Consult your Hustler service center when assistance is needed.

NOTE: The Hustler Z Shibaura Diesel tractors have a 50amp in-line fuse in the electrical system. This is the main fuseto protect the complete electrical system. It is located at the rearof the machine close to the battery. Figure 4-1

Hydraulic systemIMPORTANT: Never use hydraulic or automatic transmis-

sion fluid in this system; use only motor oil as specified.Remember, dirt is the primary enemy of any hydraulic system.

601656_0410 4-3

WARNING: Hydraulic fluid escaping under pressuremay have sufficient force to penetrate skin and causeserious injury. Foreign fluid injected into the skin mustbe surgically removed within a few hours by a doctor,familiar with this form of injury, or gangrene mayresult. Before applying pressure to hydraulic system, makesure all connections are tight and all hoses and linesare in good condition. To find a leak under pressure,use a piece of cardboard or wood — never use yourhands. Relieve all pressure in the system before dis-connecting or working on hydraulic lines. To relievepressure, lower all attachments and shut off engine.

Check oil level in hydraulic system after every 50 hours ofoperation or weekly, whichever occurs first. Check more often ifsystem appears to be leaking or otherwise malfunctioning.

Fluid level should be 1” (2.54cm) from top of reservoir. Useonly SAE 20W50 SL/SM service motor oil. Figure 4-2

Change hydraulic system filter element after first 50 hours ofmower operation, then replace filter and oil in reservoir every500 hours thereafter. Figure 4-2

The system filter is located in front of the hydraulic reservoir.A standard oil filter wrench is used to change filter, threads areright handed. Use a Hustler approved filter element only.

IMPORTANT: Prefill the filter element with clean oil, beforeinstalling, to prevent drawing air into the system pump.

Fuel system

DANGER: To avoid personal injury or property dam-age, use extreme care in handling fuel. Fuel isextremely flammable and the vapors are explosive.

DANGER: Observe usual fuel handling precautions:• Do not smoke while refueling. Extinguish all ciga-

rettes, cigars, pipes and other sources of ignition.• Do not remove fuel cap or fill tank with engine run-

ning or while engine is hot. Clean up any fuel spills.• Allow engine to cool before storing machine inside

a building.• Keep fuel away from open flame or spark and store

machine away from open flame or spark or pilotlight such as on a water heater or appliances.

• Use extreme care when handling gasoline and otherfuels. They are extremely flammable and vapors areexplosive. A fire or explosion from fuel can burnyou and others and can damage property.

• Refuel outdoors. Never refuel or drain the fuel fromthe machine indoors.

• Never attempt to start engine when there is a strongodor of gasoline or diesel fuel fumes present. Locateand correct cause.

• Store fuel in an approved container and keep it outof the reach of children. Never buy more than a 30day supply of fuel.

• Do not fill fuel containers inside a vehicle or on atruck or trailer bed with interior carpets or plastictruck bed liners. Always place fuel containers on theground away from your vehicle before filling.

• When practical, remove gas or diesel fuel poweredequipment from the truck or trailer and refuel theequipment with its wheels on the ground. If this isnot possible, then refuel such equipment on thetruck or trailer using a portable container and not afuel dispenser nozzle. If a fuel dispenser nozzlemust be used, keep the nozzle in contact with therim of the fuel tank or container opening at all times

until fueling is complete. Do not use a nozzle lock-open device.

• Never use gasoline or diesel fuel for cleaning parts.• Read and observe safety precautions elsewhere in

this manual.

WARNING: Gasoline and diesel fuel is harmful orfatal if swallowed.Long-term exposure to vapors can cause serious injuryand illness.Avoid prolonged breathing of vapors.Keep face away from nozzle and gas tank or fuel con-tainer opening.Keep gas away from eyes and skin.If fuel is spilled on clothing, change clothing immedi-ately.

WARNING: Fuel System Under Pressure! The EFIfuel system operates under high pressure, and the fuelfilter and fuel line used must be approved system com-ponents only. Use of substitute parts can result in sys-tem failure, gasoline leakage and possible explosion.

Gasoline unitsThe fuel tanks are located in the mower’s fenders.Use regular unleaded gasoline with an octane rating of 87 or

higher. IMPORTANT: Never use methanol, gasoline containingmethanol, or gasohol containing more than 10% ethanol becausethe fuel system could be damaged. Do not mix oil with gasoline.

A fuel shut-off valve is located on each mower. The locationand operation of the fuel valve will vary depending upon theunit. Close the fuel valve to prevent fuel flow to the engine. Thevalve’s two other positions will allow fuel to be drawn fromeither one or the other fuel tank. Figure 4-3

Diesel unitsThe fuel tanks are located in the mower’s fenders. These

engines requires number 2 diesel fuel only. Hustler Z Shibaura Diesel tractors are equipped with a fuel

shutoff valve located to the right rear of the seat. Rotate thevalve to the middle position to allow fuel to flow from the rightfuel tank to the fuel pump. The right position prevents fuel flowto the fuel pump. The left position allows fuel to flow from theleft fuel tank to the fuel pump. Close this valve to prevent fuelflow to the engine when servicing the fuel system or whentransporting the unit on a trailer or truck. Figure 4-4

If the diesel fuel system runs dry, use the following procedurewhen re-starting the engine:

1. Refill the fuel tanks.2. Make sure the fuel shutoff valve is turned to the full fuel

tank.3. Take the priming bulb and compress it until it becomes

firm. Figure 4-54. Try and start the engine. If it will not start after 15

seconds of cranking, repeat Step 3.5. If after trying several tries, the engine still will not start,

contact your Hustler Dealer.

Engine oil and filterCheck engine oil daily and after every 4 hours of operation.

Tractor must be setting level when checking oil. Refer to engine

manual and maintenance schedule for oil recommendation andcapacities.

Change the engine oil and filter after the first 5 hours ofoperation (50 hours on a Hustler Z Shibaura diesel unit), per theengine manufacturer’s recommendations after that. If the moweris being operated in extremely dirty conditions, then it isrecommended oil be changed more frequently.

Engine air filterPerform engine air filter maintenance per the Service Interval

chart shown elsewhere in this manual.A specially designed dry filter is standard equipment on these

tractors and supplies clean combustion air to the engine. Someexamples of the air filter are shown in Figure 4-6 & Figure 4-7.

Recommended service procedure1. Release clamps and remove element. Clean the canister

with a damp cloth.2. Before installing a new element, inspect it by placing a

bright light inside and rotate the element slowly, lookingfor any holes or tears in the paper. Also check gaskets forcuts or tears. Do not attempt to use a damaged elementwhich will allow abrasive particles to enter the engine.

3. Reinstall the dust cup. Make sure it seals all the wayaround the air cleaner body, then tighten the clamps.

4. Check all fittings and clamps periodically for tightnessand inspect hoses for holes or cracks.

5. Periodically check the intake hose for signs of ingested

dust. Locate and repair the source of ingested dirt.6. Never operate a machine without an air filter installed.

Safety filterSome Hustler tractors are equipped with a safety filter. The

filter element slides over the safety filter. NOTE: The safety filter does not require servicing unless it

becomes contaminated with dirt or moisture. Figure 4-8

OverservicingOverservicing occurs when an air filter element is removed

for cleaning or replacement before it is necessary. Each time thefilter is removed a small amount of dirt and dust could fall in theintake system. This accumulated dirt can cause a dusted engine.It only takes a few grams of ingested dirt over the normalservice life of an engine to cause a dusted engine.

Do not clean element, replace with a new element only.Cleaning used air filter elements, through improper cleaningprocedures, can get dust on the inside of the filter causing dirtingestion and engine failure.

It is important to note that whenever an air filter element iscleaned by any method, the person or company performing thecleaning assumes responsibility for the integrity of the filterfrom then on. The warranty for air filters expires uponcleaning or servicing in any manner because the condition ofthe filter after servicing is completely out of their control.Therefore, on a dust ingested engine failure, there will be nowarranty consideration if the air filter element has beencleaned or serviced in any manner.

A partially dirty air filter element works better than a newelement. Therefore, a dirty filter element is not bad for theengine unless it is excessively restricting the air flow and engineperformance is affected. The reason is simple. The media in thefilter must be porous to allow air to pass through it. When dirtyair passes through the filter, the dirt plugs some of the holes inthe media and actually acts as part of the filter media. When thenext round of dirt enters, the first dirt helps filter out evensmaller particles making the filter more efficient at stopping dirtfrom entering the engine. This is referred to as barrier filtration.

Of course, at some point the filter media becomes too cloggedto allow air to pass.

The mowing conditions will determine the frequency of airfilter element changing.

Air restriction indicatorSome Hustler units have an air restriction indicator installed

in the air cleaner. Figure 4-9Replace the element whenever the restriction indicator

reaches the change filter red line. Check the indicator daily andreplace element as needed or annually whichever occurs first.

Reset the indicator by pushing in on the yellow button aftereach element change. Fig, 4-9

Cooling system - liquid cooled unitsGasoline units

DANGER: Never remove radiator cap or overflowreservoir cap when engine is hot. Pressurized hotsteam and water may be released, causing seriousburns or possible blindness. Figure 4-10

Engine cooling is accomplished with circulated water andEthylene Glycol mixture. The radiator is equipped with apressure cap and overflow reservoir. Follow the informationfound in the engine owner’s manual for the recommendedcoolant solution.

Visually inspect the system daily prior to operating mower. Besure the engine is level. Check the coolant level only when thesystem is cold. Check the coolant level only at the overflowreservoir (Fig. 4-10). The cooling system is a closed type. Neveropen the radiator cap. Doing so may induce air into thecooling system and may cause overheating. The coolant levelshould be between the “H” and “L” marks.

Diesel Units

DANGER: Never remove radiator cap or overflowreservoir cap when engine is hot. Pressurized hotsteam and water may be released, causing seriousburns or possible blindness. Figure 4-11

Engine cooling is accomplished with circulated water andEthylene Glycol mixture. The radiator is equipped with apressure cap and recovery tank. A 50-50 mixture isrecommended for all season operation. This mixture providesfreeze protection to -32 degrees F (-35 degrees C). Should

temperatures fall below this level, additional Ethylene Glycolmust be added to the mixture.

Visually inspect the system daily prior to operating themower. Check coolant level in the recovery tank located to theleft rear of the engine (Figure 4-11). When the engine is cold thecoolant should be up to the cold mark on the recovery tank.When the engine is hot the coolant should be up to the hot markon the recovery tank. When adding coolant, pre-mix the solutionbefore adding it to the recovery tank. It is not necessary toremove radiator cap for adding small amounts of coolant tosystem.

General engine maintenanceDetailed instructions and recommendations for break-in and

regular maintenance are specified in the Engine Owner’smanual. Please refer to this manual for engine servicing,lubricating oil levels with quality and viscosityrecommendations, bolt torques, etc. The engine warranty isbacked by the manufacturer. Special attention should be paid toapplicable data which will not be duplicated here.

IMPORTANT: Refer to the Kohler EFI engine owner’s man-ual for specific cleaning instructions.

BeltsInspect belts frequently for wear and serviceability. Replace a

belt that shows signs of severe cuts, tears, separation, weather

checking and cracking, or burns caused by slipping. Slightraveling of belt covering does not indicate failure, trim ravelingswith a sharp knife.

WARNING: If the pump belt fails, loss of control willoccur especially when operating on a slope. If youlose steering control while operating the machine,place the steering control levers in the park brakeposition immediately. Inspect the machine andinvolve your Hustler dealer to resolve the problembefore continuing to operate.

Inspect the belt pulley grooves and flanges for wear. A newbelt, or one in good condition, should never run against thebottom of the groove. Replace the pulley when this is the case,otherwise belt will lose power and slip excessively.

Never pry a belt to get it on a pulley as this will cut or damagethe fibers of the belt covering.

Keep oil and grease away from belts, and never use beltdressings. Any of these will destroy the belt composition in avery short time.

Mower blade maintenanceCheck the mower blades daily, they are the key to power

efficiency and well groomed turf. Keep them sharp, a dull bladewill tear rather than cut the grass, leaving a brown ragged top onthe grass within a few hours. A dull blade also requires morepower from the engine.

Replace any blade which is bent, cracked or broken.

WARNING: Never attempt to straighten a bent bladeby heating, or weld a cracked or broken blade as theblade may break and cause serious injury. Replaceworn or damaged blades.

DANGER: Never work with blades while engine isrunning or deck clutch switch is engaged (on). Alwaysplace deck clutch switch in the disengaged position,place control levers in the park brake position and turnengine off and disconnect negative battery cable.Block up mower when you must work under it. Weargloves when handling blades. Always check forblade damage if mower strikes rock, branch or otherforeign object during mowing!

WARNING: Always wear adequate eye protectionwhen grinding mower blades.

Mower blade removalUse a 15/16” wrench to remove the 5/8” cap screw holding

the blade to the spindle shaft from underneath. NOTE: A bladeholding tool (part number 381442) is available from HustlerTurf Equipment. It is designed to prevent the blades fromrotating when they are being removed or installed on thespindle. Contact your Hustler dealer for more information.

Sharpen the blades on a grinder following pattern as shown(Figure 4-12). Touch-up sharpening can be done with a file.

Check the blades for balance following grinding. Acommercial balancing tool is available through most hardwaresupply stores, or balancing can be done by placing the blade onan inverted line punch or 1/2” bolt. Blade should not lean or tilt.Spin the blade slowly, blade should not wobble. If blade is outof balance, true it up before reinstalling.

Lay the blade on a flat surface and check for distortion(Figure 4-13 & Figure 4-14). Replace any distorted blade.

Do not re-use spindle bolts which have stripped, worn orundercut threads. Torque bolts on spindles to 118 foot-pounds(160.0 nm) when reinstalling blades.

IMPORTANT: When mounting blades, rotate them afterinstallation to ensure blade tips do not touch each other or sidesof the mower.

WARNING: Failure to correctly torque the bolt mayresult in the loss of the blade which can cause seriousinjury.

WARNING: Mower blades are sharp and can cut.Wrap the blade(s) or wear gloves and use extra cautionwhen servicing them.
