ABSTRACT:
An electric tilling machine has a motor mounted on a machine body for rotationally driving a tilling shaft provided with tilling claws. A housing/cleaning box has an upper opening and is configured to receive therein the tilling shaft and tilling claws with the machine body closing the opening of the box. Front and rear locking sections lock the machine body to the housing/cleaning box with the tilling shaft and tilling claws housed in the box. A control section keeps the motor in a controllably operable condition while the machine body is locked in the housing/cleaning box so that the motor can be operated to rotate the tilling shaft and tilling claws within the box in a cleaning mode.
