Abstract: A hollow coring tine with an extension that may be used on several types of reciprocating aerifiers provides core collection and removal from turf. In one embodiment, the extension ensures that the cores are expelled in a pre-determined position with the predetermined position adjustable between about zero and about 90 degrees to the vertical plane, the cores thereby ending up in a collecting bag, a conveyor belt, a core processor, etc. Moreover, because the cores are “caught” in a device that is off the ground, the cores do not touch the turf, directly or indirectly. When the extension is a hose, it is possible to suck the cores through the hose, directly into a collecting container. The hollow coring tine with extension may therefore prevent the turf from being damaged by other core collecting devices, like core collectors.

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.
