A tracked vehicle produces a pressure no more than 3 psi on the ground by increasing the number of contact points on the inner surface of the track. The stiffness of the track is also selected to minimize bowing between the idler wheels or rollers. The track is therefore kept substantially straight between the rollers to increase the efficiency associated with transferring power to track. The drive sprocket is positioned above the ground so as to eliminate complexity in the design and yet effectively transmit power to the tracks. Positioning the drive sp...


1. A set of wheels comprising:a shaft; an axle having a first wheel attached to one end of the axle at a first attachment point and having a second wheel attached to the other end of the axle at a second attachment point, the shaft extending beyond both the first attachment point and the second attachment point and dimensioned to be longer than the widest lateral distance between the first wheel attached to the axle and the second wheel attached to the axle; and a bearing for rotatably attaching the axle to the shaft.
