Abstract
There is provided an improved, simple and effective, powered hole-cutting apparatus, otherwise referred to as a power cup cutter, comprised of a USGA approved cutting cylinder modified with an internal plunger and an elongated threaded rod, whereby the cutting cylinder is driven into the soil by the rotation of the rod which is attached to an electric drill for easy and effortless cutting of a hole on golf course greens. With a straightforward reversal of the drill rotation, extraction of the soil plug from the newly formed hole and subsequent insertion of the soil plug into the previous hole will restore the golf course greens for golf play.The ability to cut holes quickly and efficiently is essential for golf course maintenance, but contemporary manual-operated cup cutters have fallen short of offering an efficient means of both the extraction and the insertion of the soil plug. Current methods are highly labor-intensive and require 25-30 minutes for each hole. This invention adds power to both the cutting and ejection of the soil plug from the soil as well as the subsequent insertion of the soil plug into the former hole and requires a mere 5-10 minutes a hole.The field efficien…
