Self driven laydown weeder. It runs on a 350 watts electric motor. It is geared down so top speed is around half a mile an hour, which is enough for weeding,( Most weeders don't go faster than a quarter mile an hour. ) and the advantage of gearing it down is its power. It weighs around 400 pounds and carries easily three adults of about 150 pounds each. The rechargeable batteries will last for three days on a full load.
