Abstract: An all-terrain wheelchair includes a frame which has a steering platform attached to the forward most portion. The steering platform has an operable ground-engaging pneumatic wheel which is controlled by a steering handle. The steering handle may be selectively locked in a fixed position by an operable locking mechanism. A seat is attached to the rearward portion of the frame. Attached to the frame on each side of the seat is an elongated axle with a large diameter, ground-engaging wheel. Each wheel has a plurality of uniformly spaced tubular members secured to the outer peripheral sides of each wheel and extending horizontally outwardly therefrom. A removably attached arm on each axle can be operably engaged with the tubular members to cause forward or rearward motion of the vehicle. An operable winch is mounted forwardly of the seat on the frame.
