  • Patent number: 6062992
    Abstract: An improved ball mark repair tool which can be used to relieve compaction of the earth surrounding the ball mark in a correct manner and then gently force the earth upwardly and inwardly about the ball mark so as to raise the turf and properly fill the indentation. More particularly, in one form of the invention, a downward pressure exerted upon the handle of the device will urge spaced apart earth engaging repair prongs to penetrate the earth in an area surrounding the ball mark and then to automatically move the prongs inwardly relative to one another to loosen the soil and urge it inwardly and upwardly so as to correctly restore the surface of the green to a substantially planar condition.
