DETAILED DESCRIPTION

[0027] Through the arrangement of a roller portion, a piercing tool, and a punching tool, the operator, in particular a greenskeeper, can use the handheld turf care device according to the present invention to repair a pitch mark, to remove alien growth, to take a soil sample, and to lift up a temporary cup cover. The handheld turf care device can be operated with one hand. The handheld turf care device is portable. The handheld turf care device can also be referred to as pebble tool.

[0028] To smooth out a pitch mark, the greenskeeper/operator places the palm of one hand on the roller portion and rolls the cylindrical roller portion of the handheld turf care device over the section of turf which in particular contains the area to be repaired or a part of the area to be repaired. The muscular strength introduced into the ground at right angles to the turf via the rolling handheld turf care device leads to a uniform distribution of the differently compressed and/or raised soil and thus smooths out the area. If the section of turf initially worked on only contains a part of the area to be repaired, the roller portion can be shifted so that a further section of turf can be worked on at a second time.

[0029] The greenskeeper/operator can also use the piercing tool to repair a pitch mark. The operator in this case in particular uses the cylindrical roller portion of the handheld turf care device as a handrest and introduces the piercing tool, in particular not completely vertically oriented, into the area of turf to be repaired. A pitch mark in the form of a depression is in particular levelled out by pressing together the root system and soil under the pitch mark, thereby smoothing out the surface of the turf.

[0030] To remove alien growth, the operator in particular uses the cylindrical roller portion of the handheld turf care device as a handrest and introduces the punching tool of the turf care tool into the area of turf affected so as to remove an identified alien species from the turf.

[0031] To take a soil sample, the operator again in particular uses the cylindrical roller portion of the handheld turf care device as a handrest and introduces the punching tool into the turf at a sampling point. The operator can then remove the soil sample from the punching tool at the laterally located removal hole and send it in for analysis.

[0032] To lift up a temporarily inserted cup cover or cup, the operator again in particular uses the cylindrical roller portion of the handheld turf care device as a handrest and introduces the piercing tool, in particular not completely vertically oriented, into the cup cover or cup or guides it to an edge of the cup cover or cup, and removes the cup cover or cup by levering it up or by tilting the piercing tool in the cup cover or cup during a removal process, which is in particular carried out in the vertical direction.

[0033] The arrangement of the tools and functional portions allows for a one-handed use of the handheld turf care device for various golf course turf care and golf course design tasks, and in particular a use of the cylindrical roller portion as a roller portion or handrest.

[0034] In a further embodiment of the present invention, the roller portion can, for example, in particular have a smaller diameter than the other functional portions so that forces which have significant levelling effects on the turf can be introduced into the turf almost exclusively via the roller portion as part of the repair process.
