Abstract: 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.
