Abstract
A hydromechanical all wheel drive mechanism providing both hydraulic and mechanical drive to each wheel. A valve in the hydraulic drive senses the relative wheel slippage on one side of the vehicle and compensates for that slippage by directing greater hydraulic power to the side of the vehicle which has greater traction.
