An auxiliary drive mechanism for moving a motor vehicle through mud, sand or snow includes an axle, one or two central hubs perpendicular to the axle and parallel with a pair of drive wheels for rotation about the axle. The mechanism also includes four to six outwardly extendable arms fixed to the central hub and rotatable therewith as well as a plurality of arc-shaped drive members with one of the drive members fixed to each of the outwardly extendable arms. Each of the outwardly extendable arms further includes a piston and a mass of hydraulic fluid for extending the arms outward beyond the diameter of a vehicle's drive wheels and tires. The mechanism further includes a mechanism for increasing a flow of hydraulic fluid to the pistons.
