SAFETY & PRECAUTIONARY ADVICE

Remember that your safety and the safety of others is at risk! Read these Mower Operator Instructions before using the mower for the first time.

Ensure that all shielding is in place before operating. If maintenance work is required and

the guards are removed, always replace them immediately afterwards. Repair or replace any damaged CAUTION, WARNING or INSTRUCTION decals.

Check area for debris that may be picked up and thrown by the mower causing injury or

damage.

Do not allow people to stand directly behind the mower, or direct the discharge towards people, animals, buildings or vehicles.

After striking an obstacle, stop the mower and inspect it for damage. Repair as necessary

before continuing.

If working on the mower whilst it is raised on the tractor’s three-point linkage, ensure that it is properly supported by the parking stands. DO NOT rely on the tractor’s hydraulic system alone.

Never touch the blades while the tractor engine is running.

Maintain the mower in accordance with the given schedule. Particular attention should

be given to blades and securing hardware due to the hazard they present should any part of them break loose during operation.

Familiarise yourself with your tractor’s controls. Know how to stop the tractor and

mower quickly.

Do not operate unless seated in the driver’s seat.

Take all possible precautions when leaving the tractor, such as disengaging the PTO drive, lowering the three-point linkage, engaging the tractor parking brake, stopping the tractor engine, and removing the key.

Do not allow passengers on machinery.

Ensure that only responsible, properly instructed people operate the machinery.

Inexperienced operators will require careful supervision.

Wear protective footwear and keep hands, feet, hair and loose clothing away from all moving parts.

SETTING UP THE MOWER FOR USE

i. Attachment to Tractor Attach the GMF Fieldmaster mower to the tractor’s three-point linkage

a) GMF350 mower is supplied with dual-category lower linkage pins. They are fitted

from the inside of the clevis and secured with a lynch pin on the outside.

b) The top link has two positions, a slot and a hole. For normal mowing, use the slot. This allows the mower to sit on its rollers and follow the ground contours. Adjust the top link so that the pin is between 25 and 50mm from the front of the slot when the mower and the tractor are on level ground. NOTE that the washers supplied with the top link pin must be fitted on the outside of the slots to prevent the head of the pin or the lynch pin from getting caught in the slots. NOTE: For transport, use the hole. This takes the slack out of the linkage and can prevent serious structural damage caused as the tractor bounces over bumps.

c) If the mower has not previously been attached to the tractor being used, refer to

“Driveshaft Initial Fitting” section.

d) Attach the driveshaft safety chain to prevent the covers rotating. Leave plenty of slack in the chain so that it is not broken when the mower is raised on the three-point linkage.

e) Level the tractor’s lower link arms so that both sides of the mower touch the ground

simultaneously as the three-point linkage is lowered.

f) Tension the sway chains or fit stabiliser bars to limit lateral movement.

g) Raise the three-point linkage slowly to check:

- Mower does not touch tractor tyres. - Driveshaft does not touch any part of the tractor or mower. - Driveshaft angles do not become excessive (above 35 degrees). - Mower gearbox input shaft remains approximately parallel to the tractor PTO

output shaft (within 5 degrees is satisfactory). - Driveshaft halves do not separate.

If any of these are not correct it may be necessary to limit the maximum lift on the tractor lift lever quadrant and/or relocate the top link arm.

Page 5

ii. Connecting the Hydraulics

The hydraulic wing operation is supplied with a set of hoses for both wings, allowing both wings to be raised and lowered simultaneously. The hydraulic valve needs to be of the double acting type with locked neutral position. The male quick-release couplings supplied are half inch and should suit most tractors, though some have unique fittings. Consult your tractor dealer or hydraulic specialist if the fittings are not compatible.

a) Before connecting the hydraulics, carefully wipe the quick-release couplings to avoid

contamination and possible damage to the system.

b) Check that the hoses are connected so that the hydraulic valve levers operate the wing in the desired direction. Swap the hose connections if necessary.

c) Operate the hydraulic valves to lift and lower the wings through their full cycles several times to clear any air out of the system.

DRIVESHAFT (INITIAL FITTING)

If the tractor and mower have never been used together before, proceed as follows:

Separate the inner and outer halves of the driveshaft. Attach one half to the tractor PTO output shaft and the other half to the mower gearbox input shaft. Hold the two sections of the driveshaft parallel to each other and lift the mower slowly on the three-point linkage. Throughout the lifting arc, check that the two sections do not close right up or extend so far that there is less than 100mm of inner shaft engaged. If the shaft is too long, cut equal amounts off both inner and outer shafts (including guards) using a hacksaw. De-burr and thoroughly clean the cut areas and apply a liberal amount of multi-purpose grease to the contacting steel parts.

If the driveshaft is too short, contact your dealer as it will be necessary to replace some driveshaft componentry with suitably longer parts.

OPERATION AND ADJUSTMENTS Blade types Several blade options are available for GMF Gear drive Wingmower. –Standard equipment is a flail carrier bar fitted with the swinging flail tip “Gold tips” (Part No 2365.01 LH cutting top and 2365.02 – RH cutting tip). This offers excellent performance, lifting the grass to give a clean cut and evenly spread clippings. –Heavy duty slasher type flails and also mulching type blades are available.

Cutting Height Cutting height is governed by setting the positions of the rollers and skids. Lowering the Rollers raises the cutting height and vice versa. The Rollers govern the cutting height of the whole mower. The wings are able to lift and lower with the undulation of the ground whilst the PTO is engaged thus providing a float to follow the ground contours. When unfolding the wings with the hydraulic rams, fully extend the hydraulic rams to their full extent – at this position, it will allow the wi9ngs to float 100mm below and above the level point in the float slot located at the end of the hydraulic ram To adjust the cutting height:

a) Raise the mower on the tractor three-point linkage.

b) Set down the 2 x parking stands ensuring the foot is located on firm ground – engage the height selector in a hole as required and fasten the lynch pin. Lower the machines onto the parking stands gently, and ensure the machine is stable.

c) Start with one roller only. – Loosen the bolts that hold the adjusting quadrant on the

roller and Lift or lower the roller to the required position.

d) Check that both sides of the roller are set to the same height.

e) Tighten all the bolts.

f) Set the other rollers the same as the first one.

g) Replace and tighten all bolts.

Lifting and Lowering the Wings The wings are designed to float only during operation once the ram has been fully extended and opened to it extent (giving approx. 100mm of upward and downward float) however the wings can only be lifted / raised on the hydraulic rams ONLY when the PTO is disengaged.

Page 7

DO NOT ATTEMPT TO FOLD OR LIFT

THE WINGS IF THE PTO IS ENGAGED The PTO MUST be disengaged and the blades allowed to stop completely before lifting or lowering the wings with the hydraulic rams commences. Lifting, lowering or engaging the PTO drive whilst the wings are lifted will cause SERIOUS damage to the machine and is also unsafe. CAUTION!

a) Be aware that if the wings are raised while the blades are operating, the blade on the raised wing will continue to turn. Keep all spectators clear, - Disengage the PTO first!

b) Take care when lowering the wings that spectators are clear and that the wing will not hit anything as it approaches the ground.

c) It is important that wing rams are fully extended when the wing decks are lowered and in cutting position so that ram pin locates into slot that enables independent wing floatation of 10 degrees up and down.

d) To Lift and secure the wings: - Disengage the PTO FIRST! - Fully raise the wings with the hydraulic rams. - Ensure the wings latch onto the auto

hold latches (you can test these are located correctly by gently trying to unfold the mower with the hydraulic rams, however after testing this, close the rams again as if folding the mower up)

- Ensure hydraulic controls remain in neutral position

Transport Before travelling any distance with the mower fitted to the tractor:

a) Disengage the PTO.

b) Fit the top link pin to the hold instead of the slot on the mower.

c) Ensure the wings are raised and firmly latched into folded / transport position.

d) Lock the wings in the raised position.

e) Raise the mower on the three-point linkage.

Page 8

MAINTENANCE

Maintenance requirements for the Fieldmaster GMF have been kept to the minimum without sacrificing long life, and reliable operation. The wing hinges and lift rams are on ‘greasable pins’. (4 x grease points) Items which do require maintenance or adjustment are designed or chosen to be the best available – blade rotors and gearboxes for instance feature sealed high tensile shafts, and tough steel housings with labyrinth protectors to discourage stringy material wrapping into the bearings.

ii. Changing Blades

a) Raise the mower on the tractor hydraulics.

b) Lower the parking stands onto firm ground beneath to prevent accidental lowering.

c) Fling-tip flails (‘Gold-tips’): use a 17mm spanner to undo the self-locking nut which secures the blade bolt. It is preferable to fit new bolts and nuts when changing blades.

iii. Lubrication Grease GMF after use, preferably while the moving parts are still warm. When the bearings are warm the grease flows around them and expels used grease and dirt more readily.

a) ROLLER BEARINGS: Grease nipples are fitted to each roller bearing housing. Apply three pumps (2g) of multi-purpose grease per bearing at the end of a day’s work

b) DRIVESHAFT: To grease the driveshaft it should be disconnected from the tractor end and separated. Clean the sliding tubes and apply a liberal amount of multi-purpose grease. Grease nipples are fitted to the cross of each universal joint and should receive three pumps (2g) of multi-purpose grease.

Washing Always grease the bearings before washing and avoid directing hoses at bearing housings, especially if they are still warm after use. A housing will suck water into the bearings as it cools and may severely shorten their life.

Regular Checks

PROBLEM SOLVING

Mower Vibrates Excessively

a) Incorrect PTO speed: Check that 540 rpm PTO gear has been engaged. NOT 1000 rpm. Ensure that PTO does not exceed 600 rpm.

b) Blades missing or badly damaged: Fit replacement blades of the same type (ensure that even sets are replaced).

c) Excessive driveshaft angles: Three-point linkage lifting too high. Limit the amount of lift

d) Driveshaft universal joint badly worn: Inspect and repair as required.

Mower scalping severely: Raise the cutting height.

Oil or Grease on Drive decks

a) Gearbox output seal leaking: Consult your dealer about repair.

b) Gearbox over full: Gearbox casing should not be filled above oil level plug. Drain if necessary.

c) Wing hinge pins over-greased: Clean off excess grease.

MAINTENANCE SCHEDULE BEFORE USE / EVERY 8 HOURS

FIRST 50 HOURS

EVERY 50 HOURS

EVERY 800 HOURS

a) BOLTS Check fasteners for tightness

b) BLADES Check condition and bolt tightness

c) DRIVESHAFT Clean and re grease sliding tubes Grease universal joints (2 points) Grease guard bearings (2 points) Oil quick release pins (2 points) Check for excessive wear

e) GEARBOX Check oil level – case should be half full Change oil (1 litre EP90 oil)

f) WING HINGE PINS Grease (4 points)

g) ROLLER BEARINGS Grease (2 x points per roller)

Page 10

Excessive Horsepower Required to Power Mower

a) Rotating parts not turning freely: Check that foreign material is not jamming spindles and that all bearings are in good condition.

b) PTO speed too fast: Check that the PTO is in the correct gear (540 rpm).

c) Excessive ground speed: Select a lower gear on the tractor.

Excessive Wheel Marks or Poor Cutting Finish

a) PTO Speed too slow: Increase up to 600 rpm.

b) PTO speed too fast. Check that PTO is in the correct gear (540 rpm). Also try running the tractor at lower revs and selecting a higher gear to keep ground speed up.

c) Cutting height too high: Lower cutting height.

d) Excessive ground speed: Select a lower gear on the tractor.

e) Not the best blade type for the conditions: Change to a more suitable type.
