Abstract
An edging device for trimming grass around the edges of objects set in the ground, in particular memorial markers and sidewalks in cemeteries. The edging device includes a vehicle and a frame supported thereby, and three trimmers carried by the frame for edging the sides of the object set in the ground, each of the trimmers being adapted to follow the contour of an edge of the object as the vehicle traverses past the object. Adjustment means are also provided for movably adjusting the position of one of the trimmers relative to the other trimmers so that different size objects may be trimmed. The trimmers preferably include rotatable trimmers which are mounted for rotation about horizontal axes and which includes flexible frailing elements.
