  • Patent number: 11358430
    Abstract: A suspension system for a work vehicle includes a first cylinder having a piston side, a second cylinder having a piston side, and a first valve connected to the first and second cylinders, which extend and retract during a roll condition of the suspension system. The first valve selectively enables and restricts fluid flow between the piston side of the first cylinder and the piston side of the second cylinder to adjust a roll resistance of the suspension system.

  • Publication number: 20180118284
    Abstract: A ballast assembly for a work vehicle. The ballast assembly includes a frame, a ballast weight, and a lift. The frame is included in an underside of the work vehicle. The ballast weight has a first portion and a second portion. The lift has an upper end pivotally coupled to the frame and a lower end releasably coupled to the ballast weight. The first and second portions are configured to engage with a ground surface and the frame, respectively, when the ballast weight is loaded onto the work vehicle. The first and second portions are configured to engage with the frame when the ballast weight is loaded onto the work vehicle.

  • Patent number: 9844186
    Abstract: A cleaning shoe for an agricultural machine includes a chaffer supported for movement relative to a chassis, a sieve positioned below the chaffer and supported for movement relative to the chassis. The cleaning shoe also includes a first link, a second link, and a drive shaft. The first link includes a first end and a second end coupled to the chaffer. The second link includes a first end and a second end coupled to the sieve. The drive shaft rotates about a shaft axis and includes a first cam and a second cam. The first cam is coupled to the first end of the first link, and the second cam is coupled to the first end of the second link. Rotation of the drive shaft drives the first link to reciprocate the chaffer and drives the second link to reciprocate the sieve. The second cam is angularly offset relative to the first cam by a phase angle less than 180 degrees about the shaft axis.

  • Publication number: 20120282985
    Abstract: A grain tank on a crop harvester includes a belted conveyor floor for moving grain in the grain tank toward an opening through which the grain tank is emptied. A sensor determines when the grain has depleted the tank to a substantially low level and activates the floor to remove the remainder of the grain material. A flexible strip between the active floor and the sidewalls of the grain container ensure that grain loss is minimized, if not eliminated. The active floor may be provided in an belt in which the driven side has a lower friction material so as to improve belt life.
