Abstract
Provided is an electric drive riding greens mower. The mower includes a frame which is supported for movement upon a plurality of ground engaging wheels and upon which are supported a motor generator set and a plurality of reel lawn mowers. An electric motor provides driving torque to enable movement of the mower between and over golf course greens or other surfaces to be mowed, electric motors provide driving torque for each of the reel lawn mowers. The motor generator set provides electrical energy for driving the electric motors, including the primary mover and the electrical motors for the reel type lawn mowers. The motor generator set includes an internal combustion motor which provides the mechanical energy to an electric generator which provides electrical energy in response to the received mechanical energy. Further, a mower is provided which includes fly-by-wire electric steering through an electric mower. In particular, a steering control system receives steering inputs from an operator and generates an electrical output signal to activate a steering motor in accordance with the steering input. The steering motor is powered by electrical energy and is connected to one of the plurality of ground engaging wheels to rotatably displace the wheel in order to steer the mower.
