ABSTRACT:
A triangular shaped light weight metal plate is pin connected at a front apex end to the rear of the chassis of a three or four wheeled off-the-road, vehicle intermediate of the vehicle rear wheels, for pivoting about a horizontal axis. The widened rear base portion of the triangular-shaped plate supports to opposite sides, axles for mounting a pair of conversion unit wheels for rotation about horizontal axes and in line with the rear wheels of the off-the-road vehicle. An air shock cylinder is pivotably coupled at one end to the vehicle chassis in line with and above the pin connection of the front apex end of the rear swing arm plate and at the other end, at the rear to a bracket on the plate, centered between the wheels and projecting upwardly of the swing arm plate. Endless tracks sized to and enveloping the vehicle rear wheels and the conversion unit wheels to respective sides convert the three or four wheeled off-the-road vehicle for use on boggy ground, for hill climbing, and by a suitable ski attachment to the vehicle front wheel or wheels, for use in heavy snow.
