FEATURES AND BENEFITS CHALLENGER MT600B SERIES

85

OPERATOR ENVIRONMENT

The Challenger MT600B series tractors feature a modern styled cab. It is a ROPS certified cab that provides a comfortable environment with low noise level and a large operator area. Great visibility, easy to reach controls, adjustable driving positions, heating and air conditioning, and a lot of elbow room were primary design considerations. The cab is easily entered via self-cleaning steps and wide doors on both sides of the tractor. To aid in entry and exit, extra long handles are located at the front cab corners, all within easy reach of the operator. Inside the cab is a wide adjustable air suspension seat with a variety of adjustments for a smooth ride and all day comfort. Climate controls improve interior air quality and temperature during long days in the field. Instruments are easy to read, controls are easy to reach, and vision is clear to the front, rear and sides. Many more ergonomic features have been designed into this operator enclosure that will assure continued operator comfort, convenience, and protection during long hours of operation.


86

Front Console and Instrument Panel The front console and dash feature a comprehensive range of gauges and warning lights. These gauges gives the operator immediate, detailed information on tractor performance and operating conditions. The instrument panel for the Challenger MT600B Series tractors fea-ture analog gauges for engine rpm, coolant temperature, and fuel level. A digital readout al-lows the operator to toggle between PTO speed, theoretical forward ground speed, engine rpm, and engine hours. A panel of warning and indicator lights is positioned across the top of the instrument panel. Transmission controls, hazard lighting, ignition switch, and other controls are located on either side of the console and on the steering column.

Easy to read instrument panel Analog gauges and digital read-outs keep the operator fully informed of the tractor operation and performance. Placed in full view of the operator, the primary monitored operating systems increase operator awareness of the tractor functions and required maintenance.


87

Tractor Systems Monitor The tractor systems monitor displays indicator lights on a tractor schematic whenever a tractor system is engaged or a maintenance problem is detected.

Exterior Lighting Touchpad The exterior lighting touchpad is illustrated by a tractor schematic surrounded with touch buttons and indicator lights. As the operator selects lighting combinations the indicator lights will illuminate. This allows the operator to quickly identify which external lights have been illuminated, and increase operator safety while on the road.

Digital Clock and Outside Temperature Display The Challenger MT600B series tractor now has a digital clock and an outside temperature monitor located directly above the exterior lighting touchpad. A single button allows the operator to toggle between temperature and time.


88

Dual Stage Pneumatic Cab Suspension Challenger MT600BSeries tractors now offer Pneumatic Cab Suspension as an option. The design of the system is similar to those engineered for highway trucks. Two electronically controlled air baffles at the rear of the cab constantly maintain the required air pressure as ride conditions change. In addition, hydraulic dampers and pan hard rods are mounted in line with the air baffles to eliminate unwanted oscillations. The front of the cab is also isolated from the chassis by a dual cushion of rubber. Rubber rollers in addition to rubber mounting pads further isolate the cab and reduce both vibration and noise.

Front Rubber Roller Mounts The front of the MT600B series cab is sup-ported by rubber roller mounts. These mounts help to isolate the cab structure from the chassis and reduce the amount of vibra-tion transferred to the cab. This feature also helps to increase operator comfort, re-duce interior sound level, and reduce operator fatigue.


89

Dual Stage Pneumatic Cab Suspension A convenient rocker switch, located directly below the right-hand B cab post, controls the two stage cab suspension system. When engaged in the plus position, the air baffles increase air pressure to provide a firm ride for road conditions. When the negative position is engaged, the air pressure is decreased to provide a softer ride in rough field conditions.


90

Right Hand Control Console All major tractor and implement operational controls for these large-sized row-crop tractors are ergonomically located in the arm rest and console to the right hand side of the operator. The forward portion of the console contains the Power Performance Display III, TECHstat CVT adjustment switchs , hand throttle, electronic 3-point and PTO controls. To the rear of the console, and within easy reach of the operator, are the PTO speed controls, 12-volt accessory plug-ins and pre-drilled monitor mounting locations.


91

Overhead Cab Controls The redesigned cab roof for the MT600B series creates ample room for the operator. The most visible changes are the addition of domed air vents, a larger field cooler, and the elimi-nation of the roof hatch. Also located in this area are controls for air conditioning, heating, defrosting, radio and other convenience items. The inside rear-view mirror is also located on the overhead console. By concentrating controls overhead, the operator is able to make adjustments directly within the line of sight when in the field.

Redesigned Cab Roof Features of the new cab roof include easy to reach HVAC controls, radio access, air recirculation, and an optional cab roof. More headroom and forward visibility was made possible by relocating the HVAC ducts.

Redesigned Air Ducts Air ducts with dedicated service to fewer outlets provide more efficient heating and cooling as well as more rapid air movement in the cab. The dedicated service also provides more air to the cab cooler to keep drinks even colder.


92

Recessed Step Housing By redesigning the fuel tank on the MT600B series, the steps have now been recessed within a molded cavity in the fuel tank. This provides a barrier on either side of the step to prevent the operator from slipping off the step during entry into the cab. In addition, the application of self-cleaning, non-skid treads further increases footing.

Power Adjustable Side Mirrors One of the options available on the new MT600B series cab is the ability to adjust ex-terior mirrors without leaving the operator seat. With a design similar to most modern cars, the operator can quickly adjust exterior mirrors. This saves valuable time when changing implements or moving between field and road operations. Quick adjustment increases safety by allowing the operator to keep both towed implements and traffic in view.

External Mirror Defrost By supplying electrical power to the external mirrors, the MT600B series is now able to of-fer electric defrost. This increases operational efficiency by allowing quicker starts on cold mornings. In addition, mirror defrost eliminates frequent stops to clean mirrors in winter operations.


93

Cab Air Filter Access Hatch Maintenance of the cab air filter is now more practical due to the installation of a filter access hatch. The filter can now easily be removed by standing on the exterior steps. This eliminates the need to remove the filter from inside the cab and reduces dust contamination of the operator environment.

Digital Temperature Control A digital thermostat adjustment is now optional on the cab climate control system. The digital readout allows the operator to select a specific temperature. The HVAC system will automatically adjust the fan and temperature controls to reach and maintain the desired temperature. The thermostat is adjustable to read within +/- 0.5 in both Celsius and Fahrenheit scales. In addition, an internal memory allows the system to remember your desired temperature at start-up.

Enlarged Field Cooler By redesigning the air ducting for the air conditioning system, the field cooler has been expanded to a capacity of 1.5 liters. This provides the operator with additional space for food and beverage during long days of operation.


94

Optional Super, Deluxe, Semi Active Air-ride Swivel Seat.

The computer-driven VRS semi-active operators seat

On the MT600B Series Backed by innovative co

puter technology, it utilizes a specially tuned

Motion Master damper system that allows

for continuous real-time automatic damping

force adjustments based on terrain inputs.

As often as 500 times per second, a computer

senses changes in surface and ride conditions. In re

sponse, the program sends an electric pulse to the Motion

Master damper, which contains a special fluid

that changes viscosity when exposed to a

magnetic field. By varying the strength of the magnetic

field, the fluid viscosity can be changed from that of a light

oil to that of tooth pastecontinually adjusting the ride

firmness to match field terrain and operator preference.

Adaptable to any size operator, the VRS system also in

cludes adjustments for: Operator height and Weight Fore

and aft seat position Lumbar support Seat back tilt postion

Horizontal isolation Swivel control.

Standard Air-ride Swivel Seat The MT600B Series tractors are equipped with a standard air-ride swivel seat. The basic seat provides eight different manual adjust-ments for driving comfort.


95

Cell Phone Holder An integrated cell phone holder is molded in to the B cab post directly above the instructor seat. This eliminates searching to locate the cell phone.

Premium Sound System The MT600B series Challenger tractors have a large selection of optional radios and speak-ers.

Fuse Box A conveniently located fuse box and quick release cover provide quick access to the interior fuse panel. The interior fuse panel is located behind the PTO speed selector panel on the right side of the operator.

Field Office A large field office is located under a convenient cover directly behind the instructor seat. Incorporated into the field office cover is a molded drink holder designed to retain your drink over the roughest terrain.


96

OPTIONAL INSTRUMENTS AND ELECTRICAL FEATURES

Xenon Lights The optional Xenon lighting package replaces the four standard fixtures in the cab roof with Xenon fixtures. The Xenon package provides up to 30% greater visibility by not only providing more light on the work area, but by also producing a more pure white light which is easier on the eyes than the standard halogen package.

Double Bulb Work Lights The double bulb work light option adds an additional element to the two front cab roof lights.


84

Auxiliary Electrical Outlet An extra power port can be installed in the cab. By installing a port in the left B post, the operator can plug in more electronics, thus being more efficient.

Rotating Beacons Up to two rotating beacons can be installed on the MT600B series. These lights swing down below the cab line when height is an issue.


77

POWER TAKE OFF

An independent, Power Take Off (PTO) is standard equipment on the MT600B series tractors. The PTO is driven by a live shaft from the engine. A wet, multi-disc clutch engages and disengages the PTO output shaft. A safety switch is designed into the engagement system to shut off the PTO when the engine is shut off, if the PTO is in the engaged position. Additionally, the MT600B series tractors feature a convenient PTO cut-off switch on the outside of the tractor. This enables the operator quick access to disengage the PTO from the ground. All MT600B series tractors feature dual speed, 540/1000 rpm PTO. Economy PTO is also optional on the MT600B series. A digital display of the PTO speed is provided in the dash mounted instrument panel. On the MT600B has a bolt-on access flange replaces the spring retainer clip, which provides greater strength during use under high loads.

540/1000 rpm and Economy PTO 540/1000 rpm is standard on the MT600B se-ries, and economy PTO is a factory option. This selection provides tractor PTO speeds that match tractor horsepower and perform-ance for a wide range of applications. In addi-tion, these speed selections allow the tractor to quickly adapt to numerous implements and operations for increased tractor utilization.

Independent PTO The PTO clutch can be engaged and disengaged independently of the main transmission clutch. This allows starting and stopping of PTO equipment at any time without disturbing the tractor movement, providing time savings and increased productivity.


78

Digital PTO Speed Display The dash display provides precise control of PTO driven implements and allows the operator a quick reference point for exact PTO speeds. It also eliminates guess-work associated with matching PTO speeds to engine rpms, increasing equipment accuracy and productivity.

Ground Level PTO Disengage Switch This exterior switch provides safe, quick access to disengage the PTO clutch without climbing back in the cab. Furthermore, to ensure operator safety, the PTO can only be engaged from the operator cab.

PICTURE NUMBER

Economy PTO When operating equipment that does not require maximum horsepower, economy PTO allows the engine speed to be reduced 23% from 2000 rpm to 1550 rpm, yet maintain full PTO shaft speed. Slower engine speeds reduce fuel usage, noise, and vibration. The economy PTO helps to increase tractor utilization while reducing fuel expense.

HYDRAULICS The Challenger MT 600B Series tractors feature a Closed Center, Pressure and Flow Compensated hydraulic system with a maximum flow of 39-gpm. The axial piston pump is mounted externally on the transmission and driven through a collecting shaft. This pump supplies high pressure oil (2900-psi) for remotes, and 3-Point. A second pump mounted in tandem with the auxiliary hydraulic pump supplies oil for other functions such as steering, brakes, and to the oil cooler. A third pump supplies oil for transmission operation and lubrication. A key feature of the three pump system is that the auxiliary hydraulics and the transmission oil never mix. The sump for the transmission and the sump for the remote hydraulics are located at different areas on the tractor. This reduces the potential for contamination in the transmission. The MT600B Series tractors utilize a large, submerged cartridge hydraulic oil filtration system. This filter allows the operator to perform quick, easy maintenance of the hydraulic system. Also, the addition of system monitor lights on the cab console alert the operator when service is needed to the hydraulic system. Four electronically controlled remotes, a power beyond circuit, and a load sensing line are standard on the MT600B Series. Options are available to add additional two remote valves up to a total of six hydraulic remotes. The MT600B series also features standard float and detent locks.


67

Ergonomic Lever Layout The lever layout on the MT600B series tractors places hydraulic controls in a convenient loca-tion where they can be easily reached by the operator. Ergonomic design helps to reduce op-erator fatigue and increase efficiency.

Finger Tip control The finger tip system is a standard feature on the MT600B series. The finger Tip system is comprised of a four inline switches mounted to the armrest which controls four electro-hydraulic proportional spool valves at the rear of the tractor. The finger tip system also in-corporates a float function switch which allows the activation of float for functions such as the taken pressure off hoses etc.


68

SMS Memory System The finger tip system offers a memory feature which allows operators to set proportional flow rates. This function memorizes the flow rate of the output and input of each spool valve controlling the expansion/retraction of the hydraulic cylinders. For example, the finger tip system can be used to control the rate of drop on a hydraulically lifted implement, thus reducing potential damage to the axle and hydraulic ram mounts.

On/Off Button Memory Button


69

Electronic Spool Valves Up to two additional electronic remotes are of-fered in a lever configuration on the right hand armrest. This enables the tractor to have a total of six electronic remote valves. The electronic remotes are spring return to neutral valves and do not incorporate internal detents, float, or manual flow adjustments. Roll-over locks are standard and allow the valves to be held open at full flow. However, the Power Performance display III monitor allows for precise flow and timed detent adjustment from inside the cab. In addition, PPD III al-lows the operator to engage a float position for the additional valves.

Roll-over Locks Each electronic lever remote is equipped with roll-over locks. When the locks are rolled to the right, the valves can be locked in a con-tinuous flow position. The valves will operate at full flow unless the PPD III monitor is used to control the flow. When the locks are rolled to the left, a float lock-out is engaged. How-ever, PPD III is required to obtain a float po-sition in the lever remotes.


70

Dot Matrix Display All MT600B tractors are equipped with a Dot Matrix display screen on the left-hand side of the dash. Controls for the Dot Matrix screen are located on the right-hand steering con-sole. A simple touch pad allows operators to scroll through the various screens and adjust the hydraulic functions.

Radar All MT600Bs tractors are equipped with ra-dar.


71

Power Performance Display III Software The PPD III software provides numer-ous precise control services at the opera-tors fingertips. The software is housed in the new GTA (Global Technologies by AGCO) Console I. Both the console and the software are major upgrades from the previous Power Performance Display system. Three func-tions which relate specifically to hydraulic con-trols include: Timed detent and flow control of up to five

hydraulic remotes Headland application system which stores

a timed sequence of instructions to be repeated at the headlands.

Memory functions which allow up to six

sets of information to be stored for various fields, operators, or implements.

Trailed Implement Control (TIC) TIC is a digital operating system that uses PPD III system to monitor ground speed and wheel slippage. Used with one valve, the working depth can be slightly varied to control slippage and keep field travel speed and en-gine performance at their peak. This system utilizes the Electronic Linkage Control, PPD III, and the Spool Valve Man-agement System for precision tillage opera-tion and a high level of tractor performance. TIC helps to increase field productivity and keep the tractor operating at optimum per-formance, while reducing tire wear and fuel consumption.


72

HYDRAULIC SYSTEM OPTIONS

Hydraulic Trailer Brakes The addition of optional hydraulic trailer brakes allow the tractor to transport heavier loads than what can be stopped with the trac-tor brakes. Refer to your operators manual for specific load capacities with the various braking systems.

Dual Control / Trailed Implement Control Please see the main hydraulic system section for a detailed explanation of this system.


73

HITCH AND DRAWBAR The Challenger MT600B series tractors feature an Electronic Lift Control (ELC) 3-point hitch. This hitch control system furnishes quick response to changing conditions when operating in draft sensing mode. When operating in position control mode, the ELC system will maintain the depth you have specified. Position control mode is suitable for operations requiring a continuous height such as operating a rear mounted blade. The MT600B series tractors feature rotary controls in the right console and a rocker switch on the armrest. All MT600B series tractors come with category III 3-point hitches, heavy duty turnbuckle adjustment, and adjustable sway blocks.

Category III 3-Point Hitch The hitches on the MT600B series tractors will handle mounted implements such as planters, cultivators, rear blades, mowers and much more. This increases the tractors versatility and gives the operator a greater return on investment.


74

Electronic 3-Point Hitch Control The MT600B series features easy to operate Electronic Lift Controls. These rocker-switch and dial controls are familiar to operators of mid-sized row-crop tractors. The controls allow quick customization for various tasks. The controls are easy to learn and use in operations such as cultivating, mowing, and grading. For convenience, controls are located on both the right armrest, and on the rear of the right console. This makes operation of the 3 point hitch easy regardless of the field operation. In addition, a transport lock feature allows the operator to lock mounted implements in the raised position and use the hydraulic rams to absorb the shocks from rough surfaces. Finally, an exterior, fender mounted 3 point switch allows the operator to raise and lower the 3 point hitch from the ground.

Drawbar with Clevis The drawbar on the MT600B series features a durable clevis design. A hitch pin is included in the toolbox. The hitch also includes a hanger strap for attaching safety chains. A patented quick hitch design also enables the pin to automatically drop during hook-up.


76

Front Hydraulics and Three-Point Linkage In response to the increased use and demand of front mounted implements, Challenger now offers a factory installed front three point and hydraulic option. The front linkage is plumbed in to the hydraulic manifold and is controlled by the electro-hydraulic Spool Valve Management System. The front three point linkage has an op-tional capacity of either 7,700 lbs or 12,100 lbs on all MT600B series models. The smaller 7,700 lb lift requires that the tractor be fitted with the front belly weight. The larger 12,100 lb lift does not require the front weight. Hydraulic accumulators are also available to absorb shock during transport applications with front mounted implements. The front hydraulics feature the same output as rear remote valves. An industry leading 39 gallons per minute total hydraulic flow and 2900 pounds per square inch provide enough power for even the most demanding tasks.

HITCH AND DRAWBAR OPTIONS


64

Standard Powered Front Axle Increased drawbar pulling power and front wheel traction is available on the MT600B series tractors with the Standard Power Front Axle (PFA). The Power Front Axle is designed as an integral component to the tractor, not an add-on part. The front axle is also matched for the horsepower and chassis size of each tractor model. A single piece, cast-iron, center housing and heavy outboard planetary housings provide high load carrying capacities. A maximum front wheel turn angle of 55 degrees and axle oscillation of +/-11 degrees maintains positive tire to ground contact. The MT600B series Power Front Axle features center line drive. The front axle pivots at the front differential pinion shaft. There are no universal joints in the drive line from the transmis-sion to the front axle. On the left hand console, a rocker switch engages the front axle drive electro-hydraulically on the go.

Power Front Axle Tractor wheel slippage can be reduced and drawbar horsepower can be increased with the addition of the powered front axle. Studies show that drawbar pulling power can increase approximately 20% over a conventional 2WD tractor of equal horsepower. This added efficiency increases the operators output and reduces energy loss in the field.

Power Front Axle Cast Iron Housing The one-piece center housing is designed to handle shock loads and torsional twisting while operating in a wide variety of operations. The axle housing will also handle heavier loads than the two wheel drive axle during loader use. The cast iron housing provides added durability and service life to the tractor power train.


65

Single Center Pin Frame Mount This feature provides a single mounting point for front axle. In addition to allowing a full range of motion, the single mount reduces maintenance time by having a single service point.


63

AXLES

110MM (diameter) Bar Axles The Challenger MT635B, 645B, 655B and 665B tractors are fitted with standard 110 mm diameter axles. These tractors will have the standard with a bar length of 118 inches. Bar axles and wedge clamping wheel hubs allow infinite wheel tread width adjustment. Variable axle lengths allow the tractor to fit a wide range of field operations. The 110 mm axle is adaptable for a wide range of applications. The added strength of the thicker axle also provides improved adaptability for high torque field applications

110MM (diameter) Bar Axles Challenger MT600B tractors rear reduction units are lubricated with heavy gear oil not light hydraulic oil as found in most large row crop tractors.


60

DIFFERENTIAL, BRAKES, AND FINAL DRIVES

The MT600B series tractors feature a tested, proven design on their rear differential, brakes, and final drives. The rear differential lock can easily be engaged with the use of a rocker switch located on the right console. The differential is electro-hydraulically engaged to ensure a proper, smooth engagement. Coupled with the rear differential system is the inboard rear planetary final drives. The final drives on the MT600B series tractors operate in an oil bath to ensure proper lubrication, reduced heat, and long wear life. The MT600B series tractors have smooth progressive braking supplied by a wet, rear disc braking system. This system consists of ring pistons, brake disks, and steel backing plates. In addition, the brake discs are immersed in transmission oil to keep the discs lubricated and cool. The rear brakes are hydraulically actuated using a master cylinder at the brake pedals and a slave cylinder or ring piston within the rear axle housings. Independent, suspended pedals operate the individual turning brakes. For transport, the pedals can be latched together to provide equal braking effort to each wheel. All MT600B tractors feature four-wheel braking during transport with latched brake pedals. Brake actuation will electro-hydraulically engage the brakes in the transmission on the cardon shaft, which activates the front wheel braking effect. Challenger tractors also feature a switch-operated park brake that is independent from the pedal operated brakes.


61

Automatic Four Wheel Braking When both foot pedals are llocked together during transport, four wheel braking will be engaged when the brakes are depressed. When the brakes are applied, the brakes in the transmission on the cardon shaft automatically engaged and braking power is supplied to all four wheels. This feature increases operator safety when towing heavy loads.

Differential Lock Controls The differential locks on the MT600B series tractors are controlled by convenient rocker switches located on the right console. These switches provides quick, convenient access for the operator to engage the differential locks when needed. When the differential lock is applied it locks the rear and front axle on the MT600B

Front and Rear Differential Lock Both the front and rear differential locks on the MT600B series tractors are electro-hydraulically engaged to ensure smooth, ac-curate locking and avoid transmission dam-age. This feature increases productivity and ease of operation.


62

Independent Parking Brake MT600B series tractors are equipped with an independent parking brake. Operated by a hand throw switch, this brake is independent from the hydraulic braking system. This feature increases operator safety, and reduces potential transmission damage by not having a lock gear type park brake.

Rear Wet Disk Brakes Wet rear disk brakes provide smooth, progressive, fade free braking. The wet system also keeps the disks cool during operation which maintains constant braking power and reduces fade. Wet disks also reduce wear to provide for a long service life and reduced maintenance.

Transmission Description and Operation

The following pages will help you become an expert on the TechStar CVT Trans-mission. The focus is on the relationship between hydraulic and mechanical power and their respective pathways from the engine to the tires. The TechStar transmis-sion is designed for heavy tillage work, as well as fast and efficient roading applica-tions. Use this information to familiarize yourself with the TechStar technology and to inform your customers about the reality of the TechStar CVT!


41

The TechStar transmission is comprised of two elements: a hydraulic and a me-chanical section. A torsional vibration dampener at the gearbox input absorbs shock loads. Hydraulic Section: A variabledisplacement axial piston pump (6) supplies variable hydraulic motor(s) (7). The pump and motor(s) (axial piston units) are connected and move together. Mechanical Section: The mechanical section consists of a set of planetary gears (2) and a range control (9). The collecting shaft (8), which accommodates the hydraulic motor(s), is rigidly connected to the mechanical section via pinions (collecting shaft).

F e a t u r e : P l a n e t a r y gear set

Advantage: On the transmission input side, engine torque is transmitted by the carrier at a constant ratio, either to the mechanical drive unit by the sun gear or to the hydrostatic unit via the ring gear. This is the same as in any planetary gear set for an axle. The planetary gear distributes the engine output variably to the mechanical and hydrostatic sections (POWER SPLITTING).

In the hydrostatic section the ring gear drives the variable displacement pump. The angle of the pump body determines the amount of oil that is delivered to the motor. This in turn determines the speed of the hydraulic motor(s). Thus, the speed of the collecting shaft is altered accordingly. Planetary gear set. In the mechanical section the residual torque is transmitted via pinions and the sun gear to the collect-ing shaft, where the torque values of the hydrostatic and mechanical drive trains are added together. Benefit: The planetary gear set provides optimum efficiency for the TechStar power-splitting be-tween mechanical and hydraulic power.

Feature: Two speed ranges.

Advantage: To achieve maximum efficiency at very low speeds and high power requirements in the field, as well as at high haulage speeds on the road, the transmission has two ranges.

Range 1 for field work Range 2 for haulage work

Range X Forward mph/kph Reverse mph/kph

PUMP

MOTOR MOTOR

STANDSTILL If the tractor is at a stand still while the engine is running, the pump is at its zero posi-tion, and no oil is delivered. The motor(s) on the other hand are fully displaced (45 de-grees) and blocked by the pump. The collecting shaft, and therefore the tractor, is sta-tionary (and cannot freewheel).


44

OPERATION To begin moving the tractor forward, the pump is displaced which causes it to start de-livering oil. This drives the hydraulic motor(s), the collecting shaft starts rotating, and the tractor is set in motion. The major part of the engine output is initially transmitted via the hydraulic section. The hydraulic pump and hydraulic motors are connected and are displaced together as follows.

Pump 0 degrees = motor 45 degrees (STANDSTILL) Pump 45 degrees = motor 0 degrees (TOP SPEED)

Shortly before the pump reaches its maximum angle, displacement of the motor ap-proaches zero degrees. As the motor swings back, (increasing resistance on the ring gear), the power is incrementally transferred to the sun gear, or mechanical section. This action results in higher ground speeds. Now, the motor cant take up any more oil, which blocks the pump, therefore, blocking the entire hydraulic section. The full en-gine output is now transmitted via the sun gear (mechanical section) on the input side of the transmission.

REVERSE The pump can be angled in either direction. For reverse, starting from 0 degrees, the pump is angled in a negative direction of travel, and displaced in the opposite direction of rotation. The angle of the motors remains fixed, allowing the delivery of oil to be dictated by the angle of the pump. As the pump angle increases in the negative direction, the ground speed increases in reverse.

he following features are responsible for the TechStar transmissions excellent efficiency. 1. Design of the hydrostatic units 2. Power splitting

Feature: Design of the hydrostatic units

Advantage: Conventional hydrostatic units allow a maximum displacement angle of only 30 de-grees. In contrast, the new hydrostatic units have a displacement angle of 45 degrees.

Benefit: (1) Substantially greater efficiency for the 45 degree axial piston pumps compared to conventional hydrostatic units. (2) A greater speed range is covered by the 45-degree displace-ment angle, therefore, fewer mechanical speed ranges are required.

VAR0001VAR0013

Feature: Power-splitting.

Advantage: A planetary gear set at the transmission input enables the engine output to be dis-tributed (split) in varying proportions to the mechanical and hydrostatic branches. The amount of power transmitted via the hydrostatic drive unit decreases with increasing speed. At top speed, the entire engine output is transmitted mechanically.

Benefit: This means maximum efficiency even at high driving speeds, especially since in range two the speed of 30 miles per hour can be reached at considerably reduced engine speed. In this case, the diesel engine is running at optimum consumption.

TECHstar CVT

Transmission

The TECHstar CVT transmission is the most highly respected transmission in the world. The Chal

lenger TechStar CVT (continuously variable transmission) is standard so you can fully exploit

the power and efficiency of the Challenger Endurance engines.Think a powershift transmission

is the answer in high-horsepower convenience and efficiency? Think again! Challenger

MT600B Series tractors take performance to a totally new level by including the industry leading

TechStar CVT (continuously variable transmission) as standard equipment. Through the combi

nation of proven hydrostatic transmission technology with conventional mechanical efficiency,

the TechStar CVT provides the operator with an unsurpassed level of economy and productivity

through stepless transmission technology.


51

Speed Ranges The TECHstar CVT has the advantage of offering the highest speed range in the industry. Range 1 provides 0-17 mph (0-28km) for heavy field work, while Range 2 provides 0-25 (0-40) for transport. A large speed range allows precise speed selection, which results in increased efficiency . If slower speeds are demanded, the TECHstar CVT can provide infinite creep speeds down to 60 ft/hr (18 m/hr).

Ecomomy The TECHstar CVT provides a feature which allows the operator to save fuel during transport. Being able to operate a tractor at a speed of 25 mph @ 1600 rpm makes transport much more economical. The benefit is reduced fuel costs as well as less operating time. It will also improve the life of the engine and decrease the amount of maintenance.

Efficiency The key efficiency feature of the CVT transmission is the unlimited speed selection. No longer must operators select between specific gears in different field applications. Op-erators, now, find precise speed settings which allow the tractor to operate at peak field speed while keeping the en-gine at the most productive RPM. Time, fuel, and wear and tear are all saved with this transmission.


52

Power Splitting Transmission Using both the mechanical and hydrostatic capabilities at the same time, allows the transmission to operate with extreme efficiency. Less transmission wear, and maximum operator comfort are added bonuses.

Service Friendly The CVT transmission is very easy to access for maintenance. The tractor does not need to be split. As well pressure and diagnostic tests can be preformed to allow the mechanic to solve the issue without disassembling the tractor. The benefit would be less time in the shop. Which means fewer maintenance costs.

Ease Of Operation Controlling the tractor can be done with the left or right hand. You may accelerate or decelerate as well as change direction. A third option is the drive pedal mode, commonly used in loader work and applications demanding a lot of speed variation. The operator now has the option to control the tractor according to the job.


53

Field Cruise Speeds The TECHstar CVT transmission provides operators with the ability to set four field cruise speeds. Two speeds may be set for either range. For example, one speed is set for precise planting while the second speed is set for slower turning on the headlands. With that operators can change speeds with just pushing the button without having to downshift or throttle back at the end of a row. This increases efficiency and frees up the operator to concentrate on other functions. Pre-Set Shuttle Speeds The TECHstar CVT also allows the operator to set precise for-ward and reverse take-off speeds. Speeds are displayed in the left hand LCD display screen. Speeds are determined by theo-retical speed at rated engine rpm

Fewer Parts The CVT transmission contains the least amount of moving parts compared to other powershift transmissions in the in-dustry. Fewer moving parts greatly decreases the potential for problems due to less points of wear. This creates a prod-uct that has a longer life span, increased resale value, and less maintenance cost. In fact, the only clutch in the entire system is used to engage the powered front axle.

FIELD CRUISE SPEEDS

Take-Off Speeds/ Shuttle Speeds


54

Turbo Clutch Function The Turbo Clutch allows the operator to use the brakes to stop the tractor without using the clutch pedal at lower en-gine rpms. This is beneficial to loader work, as well as any practice that demands the operator to inch the tractor along the ground. This allows the operator better control when hooking up an implement, as well as protect the machine and anything around it while performing loader work.

Separate Oil Reservoir One of the greatest advantages to the AGCO CVT is the use of a separate oil reservoir for the transmission. This isolates the oil in the system from the hydraulic remotes. This minimizes potential contamination from water and dust. As a result, transmission life, durability, and reliabil-ity is increased.

Forager Mode Forager mode allows operators to maintain a specified en-gine speed while using the foot pedal to adjust ground speed. This feature is beneficial in applications where a constant engine speed is required to maintain PTO speed or hydraulic flow.


55

Pedal Mode When the foot pedal mode is activated, the tractor operates just like the automatic transmission in a car. As the pedal is depressed both the engine and the transmission will increase in speed. This feature works very well in a loader applica-tion by allowing the operation to become more efficient, thus getting more work done. Economy Mode This feature allows the tractor to reach maximum speed at reduced engine speed. Power Mode This feature supplies more engine power to achieve maxi-mum speed under heavy load.

Engine Supervisor Automatically engaged, the engine supervisor reacts when the engine drops under load. For example, the tractor hits a tough spot while working ground causing the engine to lug down. The supervisor kicks in when the engine lugs below the percentage set by the operator. It will react by decreas-ing the ground speed to keep the engine speed from drop-ping further. When the tractor is through the tough spot, the speed will then increase back up to the initial setting. Since this is done automatically, the operator doesnt have to concentrate on keeping power to the ground. Time and fuel are saved and lessen the risk of over-throttling and keeping maximum ground speed. The en-gine supervisor also works well in a PTO application when engine speed is very important.


56

Differential, Brakes, and Final Drives The MT600B series tractors feature a tested, proven design on their rear differential, brakes, and final drives. The rear differential can easily be engaged with the use of a rocker switch located on the right console. The differential is electro-hydraulically engaged to ensure proper, smooth engagement. Coupled with the rear differential system is the inboard rear planetary final drives. The final drives on the MT600B series tractors operate in an oil bath to ensure proper lubrication, reduced heat, and long wear life. The MT600B series tractors have smooth progressive braking supplied by wet, rear disc braking systems. This system consists of ring pistons, brake disks, and steel backing plates. In addition, the brake discs are immersed in hydraulic oil to keep the discs lubricated and cool. The rear brakes are hydraulically actuated using a master cylinder at the brake pedals and a slave cylinder or ring piston within the rear axle housings. Independent, suspended pedals operate the individual turning brakes. For transport, the pedals can be latched together to provide equal braking effort to each wheel. Dual brake actuation will electro-hydraulically engage the PFA (Power Front Axle) clutch. The CVT TECHstar transmission is also equipped with a Cardon Brake which supplies additional braking power on the PFA shaft. In addition, MT600B series tractors feature a transmission park brake as standard equipment. The park brake is engaged by a security switch on the shuttle lever. When activated, a hydraulic ram applies the brake pistons on each axle preventing the tractor from moving.

Differential Lock Control Powered Front Axle (PFA) Control


57

Rear Wet Disk Brakes Wet rear disks brakes provide smooth, progressive, fade free braking. The wet system also keeps the discs cool during operation which maintains constant breaking power and reduces fade. Wet disks also reduce wear to provide for a long service life and reduced maintenance.

Automatic Four Wheel Braking (PFA Only) When both foot pedals are latched together during transport, four wheel braking will be engaged when the brakes are depressed. When the brakes are applied, the PFA is automatically engaged and braking power is supplied to all four wheels. This feature increases operator safety when towing heavy loads.

Park Lock MT600B series tractors are equipped with a park lock. The park lock is operated by a simple slide switch located on the shuttle lever. This engages a hydraulic ram located on the transmission housing. This same switch also locks the shuttle lever in place.


58

110mm Diameter Bar Axles Challenger MT600B series tractors are fitted with 110 mm diameter axles and have a length of 118 inches. This axle option provides wider rear wheel tread width ad-justments, and also provides extra space for dual wheel ap-plication. The added strength of the larger axle also provides improved adaptability for high torque field applications.

Independent, Power Take Off (PTO) is standard equipment on the MT600B series tractors. The PTO is driven by a live shaft from the engine. A wet, multi-disc clutch engages and disengages the PTO output shaft. A safety switch is designed into the engagement system to prevent the engine from being started if the PTO is in the engaged position. Additionally, the MT600B series tractors feature a convenient PTO cut-off switch on the outside of the tractor. This enables the operator quick access to disengage the PTO from the ground. All MT600B series tractors feature dual speed, 540/1000 rpm PTO. An economy 540 rpm speed is optional on the MT600B series. A digital display of the PTO speed is provided in the dash mounted instrument panel. All MT600B series tractors feature a bolt-on access flange that replaces the spring retainer clip. This provides greater strength during use under high loads.

Power Take Off

Supplied PTO Shafts All MT600B series tractors are supplied with three PTO shafts. 21 Spline, 1000 rpm, 1 3/8 Shaft 20 Spline, 1000 rpm, 1 3/4 Shaft 6 Spline, 540 rpm, 1 3/8 Shaft


59

Digital PTO Speed Display This display provides precise control of PTO driven implements. Allows operator a quick reference point for exact PTO speeds. It also eliminates guess-work associated with matching PTO speeds to engine rpms. Finally, this increases equipment accuracy and productivity.

Ground Level PTO Disengage Switch This exterior switch provides safe, quick access to disengage the PTO clutch without climbing back in the cab. Also, to ensure safe engagement, the PTO can only be engaged from the operator cab.

540 rpm Economy PTO The MT600B series can be ordered with an optional 540E/1000 rpm PTO. When operating equipment that does not require maximum horsepower, economy PTO allows the engine speed to be reduced 23%, from 2000 rpm to 1550 rpm, yet maintain full 540 PTO shaft speed. Slower engine speeds reduce fuel usage, noise, and vibration. The economy PTO helps to increase tractor utilization while reducing fuel expense.

Additional changes include an improved ground timing gear set for reduced noise pollution and a new rear oil seal for improved reliability. Finally, redesigned 4 valve per cylinder heads provide increased com-bustion, power, and fuel efficiency.


39

Single-Piece Cast Iron Block The single-piece cast iron block, on Chal-lenger engine, incorporates a stiffened ladder frame and reinforced webbing. Combined with a narrow configuration, the structural ca-pability provides for a more effective vehicle installation. Additional benefits include a tighter turning radius and improved line of sight for the operator.

Reinforced Large Capacity Oil Pan The structural features of the new oil pan on the Challenger engines give added strength to the structural block and add additional bene-fits for effective vehicle installation. Changes in the oil pan also help to achieve a tighter turning radius and improved line of sight for the operator.

Bosch VP44 Electronic Fuel Injector The engine in the MT600B series tractors use the proven design of the Bosch electronic fuel injection system. The use of an electronic system gives full authority control over the engine. Bosch has a reputation for reliability, fuel efficiency, ease of maintenance, and exceptional cold starting capability. This electronic systems also help to increase fuel economy and reduce emissions.


40

Air Intake System A major redesigned feature of the MT600B series tractor is the air intake system. In order to increase forward visibility, decrease the turning radius, and create Tier II engine cooling some components of the intake system had to be relocated. Relocation of the intake is actually a benefit to the system. Not only is the intake higher off the ground to decrease dust infiltration, but the intake also has access to cooler air which is necessary for the new Tier II engines. Finally, access to the engine air filter is also easier due to its higher location.


35
