The present invention relates to a track vehicle. The vehicle is comprised of a lightweight frame having a platform or deck portion and first and second track guiding portions. Drive drums are provided, located at one end of each of the track guiding portions. First and second electric motors are connected, via gear reducers, each to one of the drive drums. Idler rollers are located at the other end of each of the track guiding portions. First and second tracks are provided, each encircling and operatively associated with one of the drive drums, one of the track guiding portions and one of the idler drums. Each of the track guiding portions has a bottom portion with each bottom portion having a longitudinally oriented strip of low friction material fastened thereto to provide a sliding surface for each of the tracks when the vehicle is in motion. In another embodiment of the invention the deck portion and track guiding portions are blow-formed from sheet plastics material. When the plastic embodiment is manufactured the longitudinally oriented strips are eliminated and the track runs directly on the plastic surface of the track guiding portions. Further, in the plastic embodiment the idler drums are eliminated and the tracks merely slide over rounded ends of the track guiding portion.
