Abstract: A turf mower has one or more electrically powered cutting units and a traction drive system that is operatively powered by an internal combustion engine. A motor generator is also powered by the engine and is operatively connected to the engine and the traction drive system. A battery pack stores electrical energy and is charged by the motor generator during normal mowing on flat ground. When mowing on hillsides with increased mechanical power requirements above that supplied by the horsepower of the engine, a control system first removes the load imposed by the cutting units by supplying the electrical energy to the cutting units from the battery pack instead of the motor generator. If that is insufficient, the control system then uses energy from the battery pack to power the motor generator as a motor to supply additional mechanical power for use by the traction drive system.
