  • Patent number: 10538134
    Abstract: A walking beam assembly mounts onto the main frame of an agricultural trailer in place of a single axle assembly. The walking beam assembly has a main axle beam serving as the only connection to the main frame. Two walking beams, with a pair of wheels on each, are supported at opposing ends of the main axle beam. Two hubs are pivotally supported on the main axle beam at respective hub locations spaced inward axially of the main axle beam relative to the ends of the main axle beam. A pair of brace members are coupled between each hub and the respective walking beam at diametrically opposing sides of the walking beam pivot. The hubs and the brace members are pivotal relative to the main axle beam about the same walking beam axis as the walking beams.

  • Patent number: 6921330
    Abstract: A cleaning shoe of an agricultural combine is provided with a front chaffer located upstream from the main chaffer. The front chaffer has a closed upstream portion and an open downstream portion. The closed upstream portion is upwardly inclined and the open downstream portion is downwardly inclined. The front chaffer is oriented so that an air blast from the cleaning fan passes beneath the closed upstream portion and upwardly through the declined open downstream portion. The open downstream portion is provided with transversely extending louvers through which the air blast passes. The cleaning fan comprises a plurality of radially and transversely extending fan blades. Blade inserts forming air dams are located near each transverse end. The blade inserts are provided with apertures that limited the transverse air flow along the blades.

  • Patent number: 6251009
    Abstract: A straw chopper for a combine harvester having a chopper housing mounted to a combine for rotation about a transverse axis. The housing is movable from a chopping position, in which the chopper receives straw from the separator of the combine and chops and spreads the straw over a wide area, to a rearwardly raised windrowing position, in which straw falls from the combine to the ground in front of the chopper housing. By rotating the housing rearward and upward, increased access into the rear of the combine is possible. An electric motor driven lift actuator is provided to raise the chopper housing to the windrowing position where a mechanical latch locks the housing to the combine structure.
