ABSTRACT:
A vehicle having drive wheels subject to significant vertical movement is equipped with an endless track system that includes rollers mounted on the main frame ahead of the drive wheels, and track belts extending around the rollers and the main drive wheels. The roller axis is considerably displaced from the pivot axis of the beams carrying the drive wheels, and means are provided for accommodating the variations in distance between the pivot axes as the drive wheels change position vertically with respect to the main frame.
