Abstract
A variable tread width system is disclosed for a track work vehicle. The track work vehicle has a differential gear case and at least one axle shaft. The variable tread width system includes a drive wheel removably coupled to the axle shaft to receive a torque to drive the track. The drive wheel is movable relative to the axle shaft between a first orientation and a second orientation. The system also includes a saddle assembly coupled to the differential gear case. The saddle assembly includes at least one rail movable relative to the differential gear case, and the saddle assembly is movable independently of the drive wheel. The drive wheel cooperates with the saddle assembly to define a plurality of tread widths for the track work vehicle.
