TRANSMISSION Hydraulic torque converter with max. stall torque ratio 2.33 : 1. "Powershift" transmission providing three forward and three reverse speeds, with ELECTRONIC sliding control. Moving the joy-stick to neutral the transmission is disengaged. AUTO KICK DOWN function button and AUTO SHIFT function button.
Safety lock lever preventing, in "lock" position, the operation of the pilot gearshift, automatically engaging the service brakes. Torque converter/transmission oil cooling by water type heat-exchanger recirculated from the engine radiator. Transmission oil filtered by two total flow filters; one metal mesh and magnetic rod on suction line, the other cartridge type with by-pass valve on delivery line. Reduction units Central bevel gear type reduction in the centre of rear transmission housing. Double reduction modular type final drives. Reduction ratio: 1 : 10.8 POWER STEERING DIFFERENTIAL The differential steering provides the steering without ever stopping the track chain, by transmitting the power with continuity to both track chains during the steering phase, also during tight steering maneuver. With the two track chains constantly working, it is possible to push larger loads, also at maximum speed. The steering occurs by increasing the speed of one track chain and slowing down the other one the same amount; the speed difference makes the machine steering. The steering system operates as a differential and it is composed of: a pump, a hydraulic motor and the relevant controls operated by just the movement Joy-stick. BRAKES Oil-bath disc brakes A single pedal in the cab actuates a single central brake blocking the motion of the bevel gear and operates both as service brake and as parking brake. A manual system allows the disengagement of the brake in the event there is no hydraulic pressure to tow the machine in case of failure. Parking brake: automatically engaged, by the transmission safety lever ON or with engine inoperative.
Carefully read personal and machine SAFETY PRECAUTIONS (at the beginning of this manual).
