  • Patent number: 9629307
    Abstract: A mower deck includes at least one cutting chamber with a spindle-mounted rotary cutting blade. The cutting chamber includes an upper wall and a sidewall. The sidewall presents a discharge opening. A cut-off baffle extends between the spindle and the sidewall discharge opening. The cut-off baffle adjusts between an open position in which the discharge opening is at least partially unobstructed and a closed position in which more of the discharge opening is obstructed. A spreader plate lies over the upper corner of the cutting chamber near the discharge opening opposite the cut-off baffle. The spreader plate adjusts between a first retracted position spaced away from the discharge opening and a second extended position closer to the discharge opening. The cut-off baffle and the spreader plate may be adjusted to control the discharge of grass clippings from the cutting chamber.

  • Publication number: 20130239538
    Abstract: This mower blade design is intended to cut vegetation (turf, grass or other similar growth) by employing an extreme low or indirect angle of blade attack instead of a direct, head-on, 90 degree impact angle of attack used by most conventionally blades available today. Design is especially effective where the mower is to be operated in sandy or rocky soil. The design increases the life of the blade from one year season to four or five years. Design allows the blade to remain sharp since its cutting edge is out of the direct path of sand, rocks and other debris. Cutting on a low, indirect angle provides shearing or slicing action producing an improved cut similar to that of “reel” mowers. This blade is designed to be used in all conventional rotary mowers.

    Abstract: A crop harvesting header has a cutter bed to cut crop material as the harvester advances through a field. The cutter bed includes a plurality of rotatable cutters having knives extending from opposing ends of the cutters. Each cutter is ninety degrees out of phase with respect to its adjacent cutters such that the circular paths of travel of the knives of adjacent cutters overlap one another, and adjacent cutters rotate in opposite directions. Each cutter has a generally elliptical knife carrier, and a pair of knives at opposites ends of the carrier, wherein a portion of each knife extends beyond the end of the carrier to expose a cutting surface to sever the standing crop. The cutter also includes an attachment device connecting each knife to the knife carrier, and a fixed stop restricting rotational movement of the knife with respect to the carrier about the attachment device.

  • Patent number: 8151435
    Abstract: A manufacturing method includes shearing or cutting an elongated rod blank from bar stock, forge-forming a through hole in the rod blank that extends longitudinally through opposing ends of the rod blank, forge-forming a radially-extending collar on the rod blank between the opposing ends, forming attachment holes in the radially-extending collar, and extruding bearing bores in each of the recesses to form a main spindle housing. Bearings are supported in forged recesses at each end, and a shaft is rotatably supported on the bearings. The spindle housing includes a rod portion and collar both forged from the rod blank for work-hardened strength of material, and includes attachment holes and the through hole formed by pressing out slugs of material, thus facilitating recycling of scrap.
