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.

A device for making holes in the ground which comprises a tubular cutter having an open, first end for insertion into the ground, and an opposite, second end from which there extends a guide means along which a percussion weight is guided for movement, said percussion weight being intended to exert a hammering force on said second end, a tubular part connected to the percussion weight at an end thereof which lies distal from the tubular cutter such that the tubular part and percussion weight are guided for axial movement along the guide means, said tubular part being provided with a handgrip for maneuvering the percussion weight, the handgrip being mounted on the end of the tubular part that lies distal from the percussion weight; and a locking mechanism for releasably locking the cutter and associated guide means and the percussion weight and associated tubular part provided with said handgrip together against movement in an axial direction and against rotational movement.
