Abstract
A device for making holes in the ground, such as for a golf course, has a tubular cutter having an open first end for insertion into the ground, and an opposite second end from which a guide extends. A percussion weight is guided for movement along the guide and exerts a hammering force on the second end of the cutter. A tubular part is connected to the end of the percussion weight that lies distal from the tubular cutter. The tubular part guides the percussion weight axially along the guide. A handle for maneuvering of the percussion weight is attached to the top of the tubular part. The cutter and associated guide on the one hand, and the percussion weight with associated tubular part carrying the handle on the other hand, can be locked together releasably against axial movement, are non-rotatable, and are also releasably locked against rotation movement, so that the cutter can be easily removed from the ground once the hole is cut.
