Abstract

An earthworking machine having front and rear traction means and a hydraulic motor for each. The motors are connected in a closed loop parallel circuit with a pump, and one of them drives its traction means through a plural speed transmission. A first valve mechanism divides pump output fluid equally between the motors. An orifice device in the motor-pump circuit allows up to a predetermined small amount of fluid flowing to either motor to be diverted to the other motor. Second valve means in the hydraulic circuit maintains the first valve mechanism effective except at times when the transmission is in other than a low speed working position.
