Abstract: A turf maintenance vehicle, wherein the vehicle includes a traction drive system structured and operable to provide movement of the vehicle across a ground surface, and an electric motor structured and operable to provide rotation of a cutting device that includes a plurality of cutting blades. The vehicle additionally includes a vehicle controller that is configured to receive a programmable vehicle clip rate data input and monitor a groundspeed of the vehicle and a rotational speed of the cutting device as the vehicle moves across the ground surface. The controller is additionally configured to actively control the electric motor based on the monitored vehicle groundspeed to thereby actively control the rotational speed of the cutting device in order to maintain the programmed clip rate of the vehicle as the vehicle moves across the ground surface.

Abstract: A method of controlling a greens mower, wherein the greens mower includes a motor drive system variably driving a grass cutting reel and a traction system. The method includes sensing an operating parameter, comparing the operating parameter to a predetermine parameter and outputting a control signal to the motor drive system in response thereto, and further outputting a user signal to a display member representative of the control signal to alert an operator of the operating parameter. The method may also be used to control a fleet of greens mowers using a master controller. In this regard, the master controller may include an administrator or supervisor function preventing an operator from changing any predetermined parameter.

Abstract: A walk-behind greensmower includes an operator presence control for selectively determining when power from a source is delivered to an output. The operator presence control includes a handle, a bale coupled to the handle, a control arm and an electromagnet. The bale is moveable between an engaged position and a disengaged position. The control arm is moveable between a neutral position and a drive position where the control arm causes delivery of power from the source to the output when in the drive position. The electromagnet is selectively energizable in response to the position of the bale such that the control arm is retained in the drive position when the bale is in the engaged position.
