    Abstract: 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, an internal combustion motor and a plurality of reel lawn mowers. The motor generator set provides electrical energy for electric motors that drive the reel type lawn mowers. A housing encloses the internal combustion motor and motor generator set and utilizes a combination of passive noise abatement means and active noise abatement means to reduce noise generated within the interior of the housing. The passive noise abatement means is provided at plurality of locations around the motor generator set within the housing.

    Abstract: An all-electric vehicle control system arranges operator interface controls at a console between a pair of seats, either of which can be used by an operator. The console controls include a joystick arranged in communication with an electronic motor control system for driving and regeneratively braking the vehicle wheels. The joystick is also in communication with an electronic servo amplifier and an electric servo actuator that steers the vehicle electromechanically and provides a closed loop feedback circuit for steering control. Electromagnetically actuated brakes are interposed between drive wheels and electric drive motors and are energized automatically whenever the vehicle rolls to a stop, thereby holding the vehicle still. The console also includes a dynamic brake switch that can energize the electromagnetic brakes for decelerating the vehicle in conjunction with regenerative braking. A console-mounted override switch disengages the electromagnetic brakes when the vehicle is stopped so that the vehicle can be moved with external power.
