摘要:
Digging and tilling tools with both a central step and an offset shaft are disclosed. The central step allows a user to apply pressure directly over the centerline of the tool head, and the shaft, offset to one side, allows clearance for the knee. The handle on the other end of the shaft may be offset in line with the centerline of the tool head. In some embodiments, the offset shaft may be connected with the tool head by means of connecting members which connect between the shaft and sides of the tool head, leaving a central opening and acting as “stirrups” or guides for the users foot. In addition to the horizontal offset of the shaft, the tool head may be rearwardly offset from the shaft. Also disclosed are tool heads with tines having L- and T-shaped cross-sections.
