ABSTRACT:
A vehicle is provided including a main frame structure, a track assembly mounted to the main frame structure and having an single, endless ground-engaging track extending in a longitudinal direction. A pair of steerable ground-engaging wheels flank the track, constructed and arranged to exert a ground bearing pressure sufficient to change a direction of travel of the track in response to turning of the wheels to steer the vehicle. Steering structure is operatively associated with the wheels to turn the wheels. Power drive structure is mounted with respect to the main frame structure and is constructed and arranged to drive the wheels and the track simultaneously so as to move the vehicle along the ground. The wheels are constructed and arranged to be moved with respect to the main frame structure so as to change a position thereof with respect to the main frame structure, thereby permitting driving, steering and ground pressure of the vehicle to be adjusted in accordance with ground conditions.
