Manual Extract:

The axle assemblies have three main functions; to transmit the out-going twisting force (torque) at 90° to the left and right of its input direction; increase the input torque through reduction gearing and provide a means of securing the wheels and at the same time, supporting the tractor. To each of these main functions several secondary requirements are added suggesting a complex piece of machinery. In reality, each axle uses a minimum of parts to accomplish its many functions. Simplicity of design increases reliability and provides easy servicing.

Both axles are full floating, double reduction type. The axles are rigidly attached to their supporting members; the front main frame in the case of the front axle and an oscillating cradle for the rear. The cradle in turn, is pinned to the rear main frame. The first gear reduction takes place in the differential; the second in the planetaries.

Each wheel revolves on two tapered roller bearings mounted on the axle spindle. The axles are full floating in that none of the weight is supported by, or transmitted to, the axle shafts. All weight on the axle is supported by the wheels, bearing and axle housing.
