Abstract: A gasoline engine powered walk behind brush cutter for small trees and the like has a vertical blade available for cutting low-lying tree limbs and other vegetation and has a horizontal blade for cutting small tree trunks or the like. A manual grappler is affixed to the frame of the brush cutter to direct the vegetation into, for example the vertical cutting blade. This device is particularly useful for clearing shrubbery and other vegetation from overgrown lots and in confined areas where larger vehicles cannot maneuver.

Abstract: A lawnmower includes a cutter assembly having a cutter deck and at least three cutter blades disposed respectively in first, second and third cutting zones within the cutter deck. The cutter blades are coupled to a power source by a power transmission assembly. A first opening is formed in one side of the cutter deck adjacent the second cutting zone and a closure member is removably mounted on the cutter deck for closing the first opening. A second opening is formed in the cutter deck adjacent the second cutting zone and a conduit is coupled at one end to the second opening and at its other end to a hopper for conducting grass clippings from the cutter assembly to the hopper. A plurality of baffles define portions of the first, second and third cutting zones and are configured to direct clippings from the first cutting zone to the third cutting zone and from the third cutting zone to the second cutting zone. One of the baffles is configured to be mounted over the second opening and is removable to communicate the conduit with the second cutting zone.

Abstract: A self-propelled, walk-behind commercial type lawn mower having a frame with a mower deck attached to a front section of the frame, an engine mounted to a rear section of the frame, and a handle bar assembly attached to and extending rearwardly and upwardly from the rear section of the frame. The mower deck includes at least one rotatable wing section pivotally attached to the frame of the mower deck for movement between a substantially horizontal operating position and a substantially vertical non-operating position. The rotatable wing section extends the mowing width of the mower deck and allows mower to travel through narrow passageways of an enclosed mowing area. A locking mechanism secures the wing section in its substantially horizontal operating position and a substantially vertical non-operating position. A rotatable caster wheel attached to the front of the wing section may be retracted to provide maximum clearance when the wing section is in its vertical position.

Abstract: A rotary cutting deck for a mower includes a cutting deck supported by wheels at three of the four corners of the deck. The other corner of the cutting deck, namely a corner of the deck that is close to the mower, is supported by a corner suspension that lifts upwardly with a biasing force sufficient to elevate that corner of the deck above the ground. This corner suspension takes the place of the caster wheel that would normally support this corner of the deck, and thus permits the deck to be moved closer to the side of the mower, thus reducing overall mower width without decreasing the width of the cutting swath.
