Abstract
A hammer driven soil coring device for use on golf course greens having a cylindrical cutting tube that has a lower cutting edge and longitudinally extending guide slots which serve as a guide for an ejector plate. Affixed to the cylindrical cutting tube is a cutter cap to which is affixed a support tube. The support tube has one vertically oriented slot. The slot serves as a guide for a stop which serves as a device to control the depth that a tamping plate achieves when the cylindrical cutting tube is driven into the surface of the green. A hand knob extends through the slot into a cylindrical rod for extending the tamping plate beyond the cylindrical cutting tube and to lock the tamping plate into a fixed position. A bubble level is located within the support tube. An impact head is located at the end of the tube with an aperture that allows the operator to view a bubble level. A handle extends perpendicularly through the impact head as well as the support tube and is affixed to each by means of a spring lock pin.
