A drive and control system is provided for a towing vehicle pulling a towed implement, such as a tractor pulling a scraper. The drive system includes a diesel engine which drives a generator for generating electric power. A tractor axle drive motor is connected to driven wheels of the tractor through a transmission. An assist drive motor is drivingly connected to driven wheels of the scraper. A power distribution unit controls distribution of electric power from the generator to the tractor and implement assist drive motors. A control unit controls the power distribution unit as a function of an operator set power split, and other sensed parameters. A one-way clutch prevents over-speed of the assist drive motor.
