  • Patent number: 4970852
    Abstract: A grass catcher (40) for a reel mower (10). Catcher (40) includes a vent (94) which is offset relative to the longitudinal axis (55) of the catcher (40). Catcher (40) also preferably includes a panel (78a) which prevents air and grass from escaping catcher (40) on the side of catcher (40) favored by spiral blades (27) of rotating cutting reel (26). Vent (94) is preferably formed by a pair of partitions (96 and 100) which intercept the flow of air and grass and serve to dissipate the kinetic energy of the air to the point where the grass is separated out and falls to the bottom of catcher (40). A pair of slots (108 and 110) permit the egress of air from within catcher (40).

  • Patent number: 4878340
    Abstract: A grooming reel is carried on a greenmower between the front roller and the cutting reel. An improved adjustment unit is provided for changing the height of the grooming reel relative to the ground. The adjustment unit comprises an elongated rod connected to a support member on which the grooming reel is carried. A rotatable knob longitudinally draws the rod slightly along its axis to fine-tune the operating position of the grooming reel. In addition, the rod can be moved along its axis to raise and lower the grooming reel between an upper position and the operating position without disturbing the adjustment of the grooming reel in its operating position.
