ABSTRACT:
A method and apparatus for positioning and cutting grasses. In one embodiment, a power mower is provided with a rotating rake structure positioned forwardly of the cutter to prevent foreign objects from being admitted to the region of operation of the cutter. The rake structure also serves to lift, straighten and align grasses for shearing. In accordance with the preferred embodiment, a power mower is provided with forward and rearward rake structures to pick up grass blades, pull out matted weeds such as crabgrass, position the upstanding grass blades in a reciprocating cutter, and sweep grass clippings away from the cutter and into a grass catcher. A hydraulic drive system varys the drive speed by controlling fluid flow rate to a hydraulic drive motor.
