A concave assembly for an agricultural machine includes a frame pivotally connected to a structural component and a concave connected to the frame. The frame includes a trunnion having a front end and a rear end. A front arm and a rear arm are connected to the trunnion. A crossbar extends between the front arm and the rear arm. A rotating member rotatably connected to the crossbar. The concave includes a first outer support and a second outer support. An inner support is positioned between the first outer support and the second outer support. A plurality of separator bars extend between the first outer support and the second outer support.

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.

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.

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.

Drive linkage for cleaning shoe

A work vehicle, such as a motor grader, comprises a frame, a ripper, a tie bar attached to the frame, and a four-bar linkage attached to and disposed between the ripper and the tie bar for transferring a load between the ripper and the frame via the four-bar linkage and the tie bar. The four-bar linkage and the tie bar are co-planar with respect to a plane within which the four-bar linkage is movable relative to the frame. A toolbar for the ripper is also disclosed.

Ripper assembly with direct load path

An extendible axle member (or) is provided for a pivoting axle of an agricultural harvester (), the extendible axle member (or) having an elongate telescopic portion () with bearing surfaces for being slidably received in an outer axle member (or), wherein the elongate telescopic portion () is formed integral with and abuts a C-frame for supporting a steering knuckle (or).

An unloader for an agricultural harvester includes a telescopic belted conveyor that can be extended to opposite sides of the harvester. The conveyor can be operated at any selected elevation between a minimum elevation and a maximum elevation and at any extended length between a minimum extended length and a maximum extended length for the conveyor.
