a hand lever located in theright side console.

TransmissionCaterpillar power-Shuttle transmission

The standard power-Shuttle transmission provides four speed forwand reverse, full synchromesh in all gears. Constant mesh gears on

ratios permit on-the-go shifting of all gears, up or down. Natural stprovision prevents starting while shuttle is engaged. Torque conver

free-wheel clutch allows the converter stator to free-wheel during hspeed, low-load conditions, such as roading
