DRIVE TRAIN SYSTEM

DIFFERENTIAL

Housed in transmission case.

Spiral bevel gear assembly transmits power from transmission drive shaft to axles.

Distributes power in amount needed by each axle.

Differential lock collar splined to left-hand final drive shaft gives effect of solid rear axle when differential lock pedal

is pushed down to engage collar splines with splines on differential drive shaft hub.

Parking brake drum is splined to differential drive shaft hub. When parking brake is engaged by pulling up on

parking brake lever, brake band and lining clamp around drum to keep differential from moving, locking up drive

train.

DIFFERENTIAL LOCK PEDAL

Connected by mechanical linkage to differential splined collar.

Allows operator to engage differential lock so both rear wheels drive equally for added traction.
