An all seasons vehicle has a hydraulic control circuit that is used to make the vehicle highly maneuverable in which the rear treads are controllable through a speed control driving or controlling the speed of each of the hydraulic motors from a pair of hydraulic pumps connected to the motors in proportion to the position of a control element that is changed through the steering wheel of the vehicle. The control over the hydraulic motors may be increased or decreased by overriding the position of the control element and increasing the hydraulic flow of fluid to one motor or the other without interfering with the direction being imparted to the vehicle.
