Patent ID: 7900710

Claim:
An apparatus for cutting golf holes, comprising: a cup cutter; a threaded nut fixedly attached to a top of the cup cutter; a hollow shaft having a first end fixedly coupled to the top of the cup cutter such that rotation of said hollow shaft causes corresponding rotation of said cup cutter; a plunger disposed within said cup cutter; and a threaded drive shaft disposed within said hollow shaft and threadedly coupled to said threaded nut, said drive shaft having a first end coupled to the plunger and a second end configured for coupling to a motor and being rotatable thereby so that rotation of said drive shaft relative to said hollow shaft in a first direction moves said plunger upwardly within said cup cutter without rotating said cup cutter until said plunger reaches the top of the cup cutter whereby further rotation of said drive shaft in the first direction causes rotation of the cup cutter for cutting soil with the plunger being retracted within the cup cutter so that the plunger is not in contact with the soil when cutting the soil and rotation of said drive shaft relative to said hollow shaft in a second direction opposite to said first direction causes said drive shaft to rotate relative to said threaded nut thereby moving said plunger downwardly within said cup cutter without rotating said cup cutter to force out the soil contained within said cup cutter.
