Introduction
l
The tractors in this series are equipped with a POWER SHUTTLE transmission. In this transmission, reversal of the direction
of travel is managed entirely by the electronic control unit without the operator having to depress the clutch pedal. This is
achieved by way of a solenoid-operated proportional valve that directly controls the main clutch.
l
The transmission can be divided into the following sections:
m
A. Transmission-engine coupling
m
B. Gearbox
m
C. Rear axle
m
D. Rear PTO

Transmission-engine coupling
Torsional spring plate
Torsional spring plate (5) receives drive from engine (1) and transmits it through shaft (3) to gearbox (2). The engine (1) transmits
motion to the flywheel (4), on which is mounted torsional spring plate (5) designed to absorb engine vibrations and transmission
torque pitches.
