ABSTRACT:
A folding implement mountable on the three-point hitch of a tractor has a U-shaped, downwardly oriented, central member with a horizontal wing extending laterally from each side of the central member, behind the rear wheels of the tractor. Each horizontal wing has a series of downwardly extending tines spaced thereon. The tines score the earth behind each tractor wheel when the wings are horizontal. A lifting mechanism affixed to the wings and the tractor rotates the wings vertically each time the three-point hitch is raised so that the implement is folded out of the way when turning the tractor.
