  • Patent number: 6003292
    Abstract: A brush mower having deflection plate for reducing the amount of cut vegetation forwardly discharged from the intake opening at the front end of the deck. The mower additionally comprises a motor connected to the deck. The latter includes a top portion and a skirt portion extending downwardly on three sides from the top portion, thereby defining a cutting chamber. The deck also includes a blade rotatably mounted within the cutting chamber and a side discharge opening. The deflection plate has a height that is less wide than the height of the skirt portion. The deflection plate changes the airflow in the cutting chamber so that cut vegetation is directed out the side discharge opening, rather than out the intake opening.

  • Patent number: 5881543
    Abstract: A guard assembly (2) is used to protect the cutter blades (20, 21) of a cane cutter (10). The guard assembly includes a guard body (4) which is mounted to the cane cutter. A series of guard blades (6) are pivotally mounted to the guard body. The guard blades are shaped, sized and positioned to permit smaller diameter objects, such as a cane (18) of a grapevine to pass between the guard blades so to be severed by the cutter blades while preventing larger diameter objects, such as posts (26), stakes and the trunks of the grapevines, from passing between the guard blades, thereby protecting both the cutter blades and the larger diameter objects from damage.

  • Patent number: 5850727
    Abstract: Shielding for a tractor having rear mounted harvesting units such as cotton picker row units includes assemblies mounted on the tractor to allow full axle oscillation and full range of tractor steering while providing crop protection. A first assembly is connected to steering components on the front of the tractor and provides protection of the crop against damage by the front tires. A shield which turns with the steering components is cut to a profile that allows full range of steering as it interacts with a second assembly. The second assembly includes parts rigidly connected directly to the front axle casting of the tractor to define the leading edge of the shielding at the front axle casting. A bevelled front edge and layered construction prevent relatively sharp edges from contacting and damaging the crop. The parts profile assures a full range of steering where the parts interact with the front tire shield.

  • Patent number: 5600943
    Abstract: A mower suitable for cutting high grass, brush, and like growth. The mower has a plurality primary cutting elements disposed ahead of a secondary cutting element. The primary cutting elements is that which first contacts growth, cutting this growth to a predetermined height. The secondary cutting element follows the primary cutting element, contacting the cut growth and cutting the same to a final, predetermined height less than that obtained by the first cut. The primary cutting elements are preferably unencumbered by a hood or guard, but preferably are partially encircled or surrounded at the front and sides by a bumper. The bumper prevents the mower from attempting to run over or cut rigid, immovable objects, such as trees, curbs, large stones, and the like. The primary and secondary cutting elements may be a singular element or plural elements arranged abreast of one another. The cutting elements may be rigid blades or flexible members, such as stranded metal, synthetic resin cords, or chains.

  • Patent number: 5511369
    Abstract: A unique chute construction for a grass cutting mower which directs cut grass being ejected by its rotating blades through an opening in a hood surrounding its blades out of the mower in an upward fan-shaped pattern away from the mower and thereby preventing undesired clumping of the ejected grass when it hits the ground. The top portion of the hood that is adjacent to and which form an outer edge of the opening in the hood is tapered in an upward direction to form an upper first portion of the chute. A second portion of the chute forms an inside portion that employs a plate that is positioned beneath and in spaced apart relationship with the first portion and has the same taper as the first portion of the chute. The addition of this chute eliminates the need for an operator of a mower to take a second, time-consuming cut of the same grass in order to eliminate the clumps of grass that are generated by conventional mowers that do not have such a chute.
