ABSTRACT:
A grass groomer for a reel cutting unit of a mower comprises a grooming reel that rotates about a substantially horizontal axis. The grooming reel has a plurality of helical blade tip flights with the blade tips in each flight acting sufficiently against the turf to cut horizontal grass runners and to dethatch the turf. The helical blade tip flights are spaced from one another around a circumference of the grooming reel. The grooming reel also carries a plurality of helical brushes that are also spaced from one another around the circumference of the grooming reel, the helical brushes being disposed between the helical blade tip flights. The helical brushes are disposed to rotate with the grooming grass and to ruffle and wipe the grass in the turf simultaneously with the rotation of the grooming reel.
