Abstract

An integrated brush-tine vehicle for brushing top dressing material between grass blades. The vehicle employs at least four brushes to contact each blade of grass located beneath the brush pattern of the vehicle. The vehicle includes adjustable tines to cooperatively work with the brushes to move the top dressing material down between grass blades.

Claims (27)

1. An integrated brush-tine groomer connectable to a three-point hitch of a towing vehicle for moving said groomer across a surface and working top dressing material into grass blades extending therefrom comprising:

a main frame having a front end and a rear end with a longitudinal axis of movement extending from said front end to said rear end, said frame movable across a surface along said longitudinal axis of movement; and,

brushes mounted to said frame and including bristles extending downward to work top dressing material between grass blades extending from said surface as said frame is moved across the grass blades, and wherein:

said brushes are arranged in a first pattern extending on opposite sides of said longitudinal axis of movement which is an axis of symmetry of said first pattern with half of the brushes located on one side of said longitudinal axis of movement being arranged as a mirror image of the remaining half of brushes located on a side of said longitudinal axis of movement opposite of said one side, and,

tines mounted to said frame to contact said grass blades and cooperatively with said brushes work top dressing material between said grass blades;

a tine assembly including parallel members extending across said frame and having said tines mounted thereto, and further including a manual adjuster connected to said parallel members and movably mounted to said frame to simultaneously move said parallel members and tines thereon to control penetration of said tines into said grass blades; and wherein:

said tine assembly includes a plate with slots and also includes fasteners extending through said manual adjuster and into said slots for controlling movement of said parallel members and penetration of said tines; and,

said manual adjuster includes a hand graspable portion and a pair of spaced apart legs with a third leg located therebetween, said pair of legs and third leg are movably mounted to said hand graspable portion and include distal ends connected to said parallel members limiting motion between said pair of legs and third leg with said parallel members allowing rotation of said parallel members when said hand graspable portion moves transversely to said parallel members.

2. An integrated brush-tine groomer for working top dressing material into a surface having grass blades extending upwardly therefrom comprising:

a frame with a pair of side frame portions which are arranged as a first side portion and a second side portion with said frame further having a front frame portion and rear frame portion connected together to said side frame portions, said frame movable across a supporting surface with a longitudinal axis of movement;

brushes mounted to said frame and including bristles extending downward to work top dressing material between grass blades extending from said surface as said frame is moved across the grass blades, said brushes are located between said side frame portions and said front frame portion and said rear frame portion, said brushes are arranged in a pattern extending on opposite sides of said longitudinal axis of movement which is an axis of symmetry of said pattern with half of the brushes located on one side of said longitudinal axis of movement being arranged as a mirror image of the remaining half of brushes located on a side of said longitudinal axis of movement opposite of said one side; said pattern angularly positioning said brushes along said longitudinal axis of movement to contact each grass blade beneath said pattern as said frame passes completely over and past said grass blades so each of said grass blades located beneath said pattern is contacted four times pushing each of said grass blades in sequential manner in a first direction, a second direction opposite said first direction, a third direction opposite said second direction and a fourth direction opposite said third direction; and,

a tine assembly mounted to said frame and located between said side frame portions and said front frame portion and said rear frame portion, said tine assembly including multiple rods extending transverse to said longitudinal axis of movement and movably mounted to and between said side frame portions, said multiple rods each having a first end rotatably mounted to said first side portion and with each of said rods having a second end rotatably mounted to said second side portion, said tine assembly further including tines mounted to said multiple rods and extendable downwardly therefrom to penetrate into said grass blades, said tine assembly further including a tine positioner with a graspable portion with legs having distal ends movably mounted to said frame and fixedly connected to said rods to simultaneously rotate said rods as said graspable portion is moved relative to said frame while said legs pivot relative to said rods and simultaneously move said tines relative to said grass blades to control penetration of said tines into said grass blades; and wherein:

said tine assembly is located adjacent said front frame portion with said brushes located along said longitudinal axis of movement aft of said tine assembly with said tines contacting said grass blades to move said grass blades upwardly if mated down with said brushes contacting said grass blades subsequently;

said frame includes a cross member connected to and extending between said side frame portions and positioned between said tines and said brushes, said tine assembly further includes a plate connected to and extending between said cross member and said front frame portion, said tine assembly has slots in said plate and fasteners extending through said tine positioner and into said slots for controlling movement of said rods and penetration of said tines, said slots have lengths with said fasteners sliding along said lengths as said distal ends pivot.

3. An integrated brush-tine groomer for working top dressing material into a surface having grass blades extending upwardly therefrom comprising:

a frame with a pair of side frame portions and a front frame portion and rear frame portion connected together, said frame movable across a supporting surface with a longitudinal axis of movement;

brushes mounted to said frame and including bristles extending downward to work top dressing material between grass blades extending from said surface as said frame is moved across the grass blades, said brushes are located between said side frame portions and said front frame portion and said rear frame portion, said brushes are arranged in a pattern extending on opposite sides of said longitudinal axis of movement which is an axis of symmetry of said pattern with half of the brushes located on one side of said longitudinal axis of movement being arranged as a mirror image of the remaining half of brushes located on a side of said longitudinal axis of movement opposite of said one side; said pattern angularly positioning said brushes along said longitudinal axis of movement to contact each of said grass blades located beneath said pattern is thereby contacted four times pushing each of said grass blades in sequential manner in a first direction, a second direction opposite said first direction, a third direction opposite said second direction and a fourth direction opposite said third direction; and,

a tine assembly mounted to said frame and located between said side frame portions and said front frame portion and said rear frame portion, said tine assembly including multiple rods extending transverse to said longitudinal axis of movement and movably mounted to and between said side frame portions, said tine assembly further including tines mounted to said multiple rods and extendable downwardly therefrom to penetrate into said grass blades, said tine assembly further including a tine positioner connected to said rods to simultaneously rotate said rods and simultaneously move said tines to control penetration of said tines into said grass blades; and

said tine assembly is located adjacent said front frame portion with said brushes located along said longitudinal axis of movement aft of said tine assembly with said tines contacting said grass blades to move said grass blades upwardly if mated down with said brushes contacting said grass blades subsequently, and

said frame includes a cross member connected to and extending between said side frame portions and positioned between said tines and said brushes, said tine assembly further includes a plate connected to and extending between said cross member and said front frame portion, said tine assembly has slots in said plate and fasteners extending through said tine positioner and into said slots for controlling movement of said rods and penetration of said tines; wherein;
