Abstract
A vibratory device (10) for dispersing a topdressing and correcting the grain in greens. A deck (30) is supported by a frame (18) with a linkage (36) for raising and lowering the deck (30) with rest to the green. A shaker tray (76) is vibrated within the deck (30) by a vibrator (108) attached to the deck (30). A brush frame (94) is carried within the shaker tray (76) for vibrating against the tips of the grass blades in the green to shake the topdressing into the thatch and to straighten the grass blades. The linkage (36) to raise and lower the deck permits height adjustment of the brush frame (94) with respect to the grass blades so that the brush bristles (106) just tickle the tips minimizing injury to the grass.
Claims10
A vibratory device for attachment to a tow vehicle for dispersing a topdressing and correcting the grain in greens, said device comprising:
- a frame having a top side and a bottom side, said frame mounted on legs such that the bottom side is elevated above the green, each leg mounted on a rotary member for rolling the frame across the green;
- a deck with a top side and a bottom side, said top side of the deck attached to the bottom side of the frame, said bottom side of the deck having a pair opposed side rails;
- a shaker tray with a top side and a bottom side, said shaker tray adapted to be reciprocated between the side rails of the deck, said shaker tray having a pair of opposed side rails in which is mounted a brush with a plurality of bristles;
- a vibrator attached to the frame and the top side of the shaker tray to vibrate the shaker tray in the deck,
- whereby the bristles in the brush are vibrated against the grass blades in the green.
