1. Transmission. Eight speeds are provided in forward and six in reverse. A transmission modulator control
(inching pedal) disengages the transmission from the drive wheels. Inching allows the operator to vary the
machine ground speed while keeping engine speed high for quick implement response.
2. Rear Axle Differential and Lock Differential. A four-wheeled tandem rear axle arrangement houses axle
shafts driven by a lock-unlock equipped differential. The axle shafts turn the final drive sprocket chains through
planetary reduction gears. The sprocket chains then drive the final drive sprockets.
3. Final Drive Assembly. The sprocket chains drive the final drive sprockets and axle shafts which turn the rear
wheel spindles inside the tandem axle housing.
