ABSTRACT:
The lawn and garden tractor has independent electric motors for both driven wheels. The motors are combined with reduction gearboxes, and the wheel is mounted on the output shaft of the gearbox. There is no mechanical axle connection. The power to the motors is controlled by an automatic controller as to wheel speed, power being increased/decreased in accordance with whether the wheels are under-running or over-running relative to manually-controlled speed setting. Steering is controlled by potentiometer on a mechanical steering wheel, or by joy-stick control. The joystick may be on the tractor, or remote. The drive system is suitable also for four-wheel drive.
