Kubota has developed a radio-controlled tractor equipped with a lawn mower. Since the operator can radio-control this tractor from a remote site, the operator will receive no dust or vibration from the vehicle or mower. In addition, there is no risk of injury, even if the tractor tips over on a steep slope.The tractor uses a variety of mechanisms whose development Kubota has pioneered. These features have improved the operating efficiency and maneuverability of the radio-controlled tractor. In addition, automatic brakes, an automatic differential locking system, and a variety of safety measures have made operation easier and safer.
