ABSTRACT:
This disclosure relates to a grass trimming apparatus which may be used for trimming and cleaning grass on cemetary grave markers or the like. The grass trimming apparatus of the present invention basically comprises a grass lifting device such as a rotating brush which digs loose dirt and stones and lifts grass and thatch-like material up and off the face and peripheral edges of flush mounted grave markers so that a sequentially mounted grass cutting device can trim the grass lifted by the brush. The rotating brush is movable from a downward operative position to an upward position for travel between various grave markers in the cemetary, and may be detachably mounted for service. The grass cutting device or mower deck is similarly mounted to be movable between operative and travel positions. The entire grass trimming apparatus of the present invention may be mounted adjacent an associated vehicle such as a tractor which may be used to provide the necessary power, be it hydraulic or otherwise, to operate the present device. In such case, the entire grass trimming apparatus would be able to be transpositioned between an operating orientation alongside the vehicle, to a transport or storage position disposed rearwardly of the vehicle.
