Claim 1
Independent Claim
156 words
In an all terrain vehicle of the type having a molded hollow body, first and second axles located in proximity to the front and rear ends of said body and a third axle located midway between said front and rear ends, wheels having low pressure pneumatic tires thereon mounted on said first, second and third axles, motor means, and transmission means for coupling said motor means individually to the wheels on opposite sides of said body, the improvement comprising: a. a fourth axle having wheels thereon, said axle being pivotally mounted with respect to said body and extending outwardly along the longitudinal axis a predetermined distance from said body and b. shock absorbing means for freely allowing motion in one direction but restricting motion in the opposite direction affixed to said fourth axle and to said body for urging said wheels on said fourth axle downwardly against the ground surface on which the vehicle is operating.
