Abstract
A self-propelled single axis motor driven work machine for propelling and/or for driving communal or agricultural work devices mounted on a mounting device. A drive motor is fastened to an undercarriage or machine chassis, and a drive axle protrudes transversely of the direction of movement from both sides of the undercarriage or machine chassis and is hydraulically driven by the drive motor. The drive axle has at both ends a wheel connected to a drive shaft which is connected on the operator's side thereof to the undercarriage and machine chassis with mounted guide rods for manually steering the work machine and for arranging an actuating member for operating and controlling drive units having hydraulic pumps and hydraulic motors, for driving and steering the wheels of the drive axle. The hydraulic pump connected for steering to the actuating member includes an adjusting member which is coupled adjustably to a control shaft that is mounted to a frame that is mounted to the undercarriage or machine chassis so as to be pivotable about an axis approximately perpendicular to the ground.
