Power Hoe With Reciprocating Blades In Sliding Engagement With Each Other
US Patent:
4452316, Jun 5, 1984
Filed:
Aug 19, 1981
Appl. No.:
6/294135
Inventors:
John W. Edwards - Natrona Heights PA
International Classification:
A01B 110
US Classification:
172 41
Abstract:
A power hoe includes a power source, two substantially planar hoe blades positioned in apposition to one another and power connecting structure to synchronizingly reciprocate the blades in sliding engagement relative to each other. The sliding engagement causes the blades to be self-cleaning. Orientation of the tapered end of each hoe blade perpendicular to the direction of reciprocation effects a ground penetrating action of the hoe blades.
