Abstract: This invention relates to the cutting or trimming of grass directly over the top of the pop-up sprinkle head's shaft. In the past the grass and roots would cross over the path of the sprinkle's pop-up shaft restricting or stopping the upward movement of the shaft and deflecting or stopping the water spray pattern of the sprinkle. This invention will cut a very narrow cylindrical shaped hole down to the top of the pop-up head of the sprinkler eliminating the unsightly bowl shape cut in the grass of the prior patents and leaving a clean unrestricted small opening in the grass.

Abstract: A grass trimmer (10) for a sprinkler head (12) on a water supply pipe (14) in a lawn (16) comprising a handle (18) with a handgrip (20) transversely attached to a top end of the handle (18). A tubular cutting assembly (22) is also provided. A structure (24) is for connecting a bottom end (26) of the handle (18) to an upper end (28) of the tubular cutting assembly (22). When the tubular cutting assembly (22) is placed over the sprinkler head (12) and the handgrip (20) is turned back and forth, the tubular cutting assembly (22) will remove grass (30) from about the sprinkler head (12) in the lawn (16).

Abstract: A golf marker cleaner having a housing with a central bore with a set of individually retractable soil-engaging arms, each having one end pivotally connected to the housing and a second end with a soil-engaging tine to prevent movement of the soil-engaging arm, with a rotatable shaft extending through the bore in said housing and rotatably journaled therein to permit rotation of the shaft about the central axis, and a resilient pad attached to the shaft, with the resilient pad having a surface for rotatingly engaging a top surface of a marker on a golf course without marring the surface of the marker and to limit the axial displacement of soil-cutting blades connected to the shaft, with the soil cutting blade having U-shaped cutting blades located thereon to permit an operator to rotate the soil-cutting blade to cut free an annular portion of soil and grass located around the golf course marker.

Abstract: A device is disclosed for trimming grass from around a pop-up sprinkler having an annular top and a pop-up head concentrically mounted within the top. The device comprises a handle having a grip mounted on one end. A circular cutting element is mounted on the opposing end, the circular cutting element having a diameter larger than that of the annular top. A centering device mounted within the interior of the circular cutting element engages the pop-up head and centers the device over the top.

Abstract: A grass trimming device arranged to provide for circular removal of plug members in surrounding relationship about such components as sprinkler heads and the like is formed with a cylindrical body having continuous serrated lower edge spaced from an annular upper edge, with the cylindrical body defined about a body axis, with a handlebar mounted through the cylindrical body orthogonally relative to the axis adjacent the upper edge. The invention is arranged to include a herbicide dispensing structure selectively mounted into the cylindrical body and into the handlebar structure.

Abstract: A generally cup shaped cutting head for fitting over and around the sprinker head includes a generally circular cutting edge for cutting around a sprinkler head, and a cleaning brush mounted concentrically within the cutting head and recessed from the cutting edge for engaging and cleaning the surface of a sprinkler head, with the cutting head detachably mounted on the end of an elongated drive shaft which is adapted to be driven by an electric drill motor or the like.

Abstract: A cup-shaped grass cutting implement which is removably attached to existing rotary cutting heads of powered edgers of the type that can orient the cutting head to rotate about a vertically displaced axis. A quick disconnect feature which allows the cup-like attachment to be retained by the flat blade of such a powered rotary cutting head without interfering with the already assembled blade. The invention provides for a quickly administered pair of retainment fingers which surround the flat cutting blade at points slightly apart from the shaft arrangement for rotating such flat blades.

Abstract: A portable power tool particularly suited for use in removing plant growth and debris from the peripheral zones of upstanding heads for subterranean sprinkler systems. The tool is characterized by a portable frame adapted to be positioned above an upstanding sprinkler head in an operative relationship therewith, a drive shaft mounted on the frame having a rotatable cutting head connected thereto for cutting an annular swath about the sprinkler head in response to rotary motion imparted to the drive shaft, and an electrically energizable motor connected to the drive shaft and adapted to respond to a positioning of the frame into an operative relationship with a sprinkler head for imparting rotary motion to the drive shaft.

Abstract: A grass-clearing device for lawn sprinkler heads, wherein the grass and sod surrounding the in-line, sprinkler head is to be trimmed therefrom, to provide an unobstructed flow of water from the sprinkler head. The device comprises a pair of adjustable, cutting blades slidably secured to a support body, the blades being provided with a centering mechanism whereby the blades can be adjusted for proper cutting relative to the size of the sprinkler head. A telescoping, handle shaft is secured to the support body, the upper end of the handle including a foldable, hand grip connected thereto.

Abstract: A powered device is disclosed herein for removing soil, weeds or the like from the immediate area beneath a sprinkler head which includes a central shaft having a forward end engageable with the sprinkler head as a guide and a U-shaped member fixed on the shaft so as to rotate therewith. Each leg of the U-shaped member extends downwardly to clear the peripherial edge of the circular sprinkler head. A cutting blade is angularly secured to each end or leg of the U-shaped member so that a forward portion thereof extends underneath the sprinkler head and so that a rearward portion extends outwardly in a diverging relationship to the sprinkler head. Power drive is releasably coupled to the shaft for rotation of the cutting blades about the sprinkler head.
