REAR AXLE/DIFFERENTIAL AND LOCK DIFFERENTIAL
0003 00
1.
The differential is mounted to the forward lower section of the transmission. It provides gear reduction and transfers
power through the final drives to the rear wheels at each side of the machine. It allows power to be transmitted equally
to both sides even though the wheels on one side are moving more slowly when the machine is turning.
2.
A differential lock-unlock feature includes a hydraulic valve that operates a clutch, which causes drive wheels at both
sides to travel at the same speed and pull evenly to reduce slippage.
