ABSTRACT:
A vehicle suitable for on-and off-road use has a track drive with auxiliary frames mounted under the vehicle frame between front and rear wheels, the auxiliary frames having continuous tracks on carrier wheels driven by hydraulic motors, each auxiliary frame being independently vertically displaceable relative to the vehicle frame by means of corresponding lifting cylinders between a fully retracted position for travel on wheels only, and a fully extended position for tracks only travel. The lifting cylinders are adjustable for leveling the vehicle to a horizontal position on uneven ground while the vehicle is supported on the tracks. Such an auxiliary track drive can be installed in an existing motor vehicle for improved off road usage and particularly for use in soil sounding applications.
