ABSTRACT:
There is disclosed a memorial marker trimmer including a horizontal rotary drum mounted from a supporting vehicle and rotated about a horizontal axis. Mounted at equidistance about the periphery of the drum are four axially extending rows of leather thongs forming whips about eleven inches long and a quarter-inch square in cross section. Consequently, when the rotor is driven at high r.p.m.'s, the thongs will whip radially outwardly in vertical planes with the free extremities thereof engaging the grass to be trimmed during their downward sweep and breaking the top portions of the individual grass blades from the stalks thereof, as well as mulching the cuttings and sweeping clean obstacles over which the drum is passed.
