A tracked vehicle apparatus adapted to receive a wheeled vehicle and to be driven by the wheeled vehicle, the tracked vehicle apparatus comprising:
- a chassis adapted to receive on each side thereof:
- plural guide wheels, and at least one drive wheel rotatably engaged with the chassis, a continuous track engaged for rotation about the guide wheels and the at least one drive wheel, and for supporting the chassis in vehicular movement;
- a drive roller assembly adapted for receiving an applied rotational force and for transmitting the rotational force to the at least one drive wheel through an open differential gear box;
- a docking stile, adapted for receiving an applied turning force, the docking stile engaged with a brake cylinder such that rotation of the docking stile actuates the brake cylinder in a first rotational sense and releases the brake cylinder in an opposite rotational sense;
- a disc brake caliper assembly functionally engaged with the brake cylinder for retarding the drive wheel when the docking stile is rotated in the first rotational sense.
