Abstract:
1. A tiller comprising: a frame supported by at least one wheel; an upright assembly extending from the frame; a drive mechanism supported by the frame and including a motor having an output member; a tilling implement having a drive shaft that is driven by the output member in a first rotational direction, the tilling implement comprising at least one tine plate; an unjamming mechanism including a key that is selectively rotatable in a first receiving member, wherein rotation of the key causes the drive shaft to rotate in a second rotational direction, opposite the first rotational direction; and a second receiving member, wherein the key must be inserted into the second receiving member during operation of the drive mechanism, and withdrawal of the key from the second receiving member causes the drive mechanism to be disconnected from a power source of the tiller.
