Abstract: A grass treatment system includes a first ground engaging rolling element, a second ground engaging rolling element, a comb having a leading edge including a plurality of comb teeth spaced apart at intervals, the comb is mounted between the first and second rolling elements and transversely to a direction of travel, a substantially cylindrical brush positioned above the comb and configured to engage at least a portion of a top surface of the comb, wherein the brush rotates relative to the comb to propel debris lifted from an area of turf grass by the comb.

Abstract: A method of removing debris from an area of turf grass can include providing a grass treatment system including a comb having a leading edge comprising a plurality of comb teeth, wherein the comb is mounted transversely to a direction of travel, and a substantially cylindrical brush positioned above the comb and configured to engage at least a portion of a top surface of the comb, wherein the brush rotates relative to the comb. The method can include positioning the grass treatment system closely adjacent to the turf grass such that the comb engages debris on and around the turf grass surface, and moving the grass treatment so that (i) the comb engages the debris, (ii) the rotating brush removes at least a portion of the debris from the surface of the comb, and (iii) the rotating brush does not come into contact with the turf grass.
