Abstract
An electric drive riding greens mower, with a frame supported plurality of ground engaging wheels, supports a battery power source, an operator station and a plurality of reel lawn mowers. An electric motor provides the driving torque for moving the mower over surfaces to be mowed. Individual electric motors provide driving torque for each of the reel lawn mowers. Electrically driven linear actuators move the reel lawn mowers between a lowered operating position in which the reel lawn mowers engage the turf being mowed and a raised non-operating or transport position. An operator oriented controls layout, which includes an operator communication panel, is provided on the mower. All electric operation provides emissionless extremely quiet operation. The mower includes an electric control system having a battery power source providing a plurality of output voltages to drive the various electric components. The control system provides a first voltage to power control circuits, a second, higher voltage to power smaller motors, and a third highest voltage to power the drive motors and reel mower motors.
