Abstract

In an electric tilling machine, a housing/cleaning box houses a tilling shaft and tilling claws provided on the tilling shaft, and it has an opening closable by a machine body. 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. Control section keeps the motor in a controllably operable condition while the machine body is locked the housing/cleaning box via the locking sections.
