  • Patent number: 4558746
    Abstract: A lawn working implement having rigid teeth which is towed behind a small tractor or other such apparatus to thatch, sow or work a lawn. The implement is compact and highly maneuverable, yet applies pressure to its rigid tines to work the lawn effectively and efficiently. Swivel mounted wheels allow the implement to follow the tractor directly in its path so that confined areas of yards may be reached. The height of the tines above ground may be adjusted by varying the setting at which the wheels are attached to the frame, and their pressure against the ground may be adjusted by adding bricks, cement or other heavy material to a cavity in the implement. The implement has a hitch for attaching a sweeper or lawn vacuum to be towed behind it.
