A power hoe for working soil. The power hoe includes a drive shaft contained inside a housing and driven by an electric hand drill. A drive pin mounted to a drive plate at the end of the drive shaft is inserted into a piston housed in a sleeve. The piston is allowed to slide back and forth within the sleeve thus allowing the rotational motion of the drive pin to be translated to harmonic reciprocating motion at the sleeve in a direction perpendicular to the path of the moving piston. The sleeve is attached to a cutting head, thus causing the cutting head also to reciprocate. The cutting head can be adjusted so as to change the length of the stroke; the speed of the stroke varies with the speed of the hand drill. A curved cutting edge on the blade of the cutting head compensates for the arc of the blade as it reciprocates, allowing for more efficient working of the soil.

A power implement comprising: a drive shaft within a housing; means for connecting a motor to the drive shaft so as to provide rotational motion thereof; a drive plate attached to said drive shaft and rotated thereby; an end of a drive pin mounted to said drive plate and the other end housed in a sleeve; a cutting head mounted to the sleeve such that the sleeve and the drive pin work in harmony so as to translate the rotational motion of the drive shaft to a reciprocating motion at the cutting head; a support rod connected to said sleeve for supporting the cutting head, wherein said support rod is joined to said sleeve by a connecting member; forks mounted at the end of said housing and attached to said support rod so as to support said cutting head while allowing said cutting head to reciprocate with respect to said housing; and baffles adjacent to said sleeve and said piston and a dust cover surrounding said forks, said sleeve, and said piston so as to protect against the entrance of dust and foreign matter therein.
