  • Patent number: 5699863
    Abstract: The invention discloses apparatus for grooming, leveling and conditioning athletic fields comprised of a leveling trowel having beveled ends. Soil is worked using elastomeric flails disposed into contact with the surface by a rigid weight bar pivotally mounted on the upper surface of the independently pivotable flails. The grooming apparatus may be mounted with a two or three-point hitch assembly or towed by a drawbar from any utility tractor or other landscape vehicle.

  • Patent number: 5477927
    Abstract: 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.
