Abstract:
A base frame with four wheels, two of which are powered by separate hydraulic motors connected in series so that the fluid flowing through one motor then flows through the other. A speed control is provided whereby the constant output of a hydraulic pump either passes entirely through the motors or is partially bypassed around the pump.
