  • Patent number: 5322130
    Abstract: A ball repair tool has a plurality of fingers which extend first vertically into the surface of the green. After extending into the green vertically a specified distance, the plurality of fingers are forced conically inward to force both dirt and grass into the unrepaired ball mark. Once repaired, the fingers are retracted leaving a repaired ball mark. The holes made by the blades of the fingers aid in the repair of the ball mark by aerating the area around the repaired ball mark. The vertical extension of the fingers into the green before the conical motion to force dirt and grass into the ball mark provides sufficient depth of the repair area to adequately support the green area.
