A powered brushing system can be mounted on triplex mowers, front mowers, utility tractors and other motor vehicles for use in conjunction with the aeration and maintenance of golf courses, particularly tee areas and greens. The holes left by core or spike aerators used to condition turf must be filled with sand or other topdressing. Elongated rotary brushes extend radially in a horizontal plane from a vertical axis about which they rotate. Vertical bristles extend downward and touch the ground while rotating to stir the topdressing and sweep it to evenly fill aeration holes. The preferred embodiment is comprised of five rotary brushes having overlapping swept areas and synchronous rotation. The swirling motion of the bristles of the counter-rotating rotary brushes may also be used effectively to remove grain which has developed in turf. The brushing system can, in this manner, greatly improve the evenness with which mowing of fine turf areas is performed. Rotary power is provided to the brush system by hydraulic or hydrostatic drive motor, power take-off, or independent engine.
