摘要
A gang reel mower has a hybrid engine, generator and battery pack electric power system driving a pair of electric wheel motors for propelling the mower and for driving individual reel motors for powering a plurality of reel cutting units. master controller is programmable with a selected clip and maintains the selected clip whether the mower travels straight ahead or is turning. The output power of the generator is damped and is gradually increased during high electrical loads to prevent step responses in the engine and thereby limit engine droop. During regenerative braking of the mower, the generator can be driven as a motor to use the engine as a load. This limits the voltage produced by the traction motors during regenerative braking from damaging the electrical system or overcharging the battery pack. Moreover, maximum transport and mowing ground speeds are automatically reduced during some turns of the mower.
