A cleaning system for an agricultural combine harvester includes a pan and a crop divider. The pan includes a stepped floor to receive crop material thereon and is arranged for fore-aft reciprocating movement to advance the crop material in a crop-processing direction. The crop divider is mounted with the pan for fore-aft reciprocating movement therewith and extends in a fore-aft manner and above the stepped floor to partition the crop material laterally. The crop divider includes a body and a periphery disposed about the body. The body includes a multi-dimensional, clustered array of crop strokers extending laterally to engage the crop material to advance the crop material in the crop-processing direction during fore-aft reciprocating movement of the pan.

Cleaning system with crop divider stroker array

An exemplary sieve mechanism is configured for separating grain from chaff. The sieve mechanism generally includes a frame and a louvered region including a plurality of louvers mounted to the frame. The sieve mechanism further includes and an unlouvered region lacking louvers such that a gap is defined adjacent the louvered region.

Partially-unlouvered sieve mechanism

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.

Combine harvester concave assembly and attachment method

Systems and methods for automatically establishing a gap between a concave and a rotor of a rotary crop processing system are disclosed. Establishing the gap may include displacing the concave towards the rotor until contact is detected therebetween. Contact may be detected using a sensor configured to detect contact between the rotor and the concave. The sensor may be a knock sensor. The concave is displaced away from the rotor when contact is detected until contact between the rotor and the concave is no longer detected. One or more actuators may be coupled to the concave to move the concave relative to the rotor. In some implementations, the actuators may be operated in sequence to form the gap between the rotor and the concave.

Systems and methods for automated concave leveling of combine harvester

A harvester includes a chassis, a separation frame movably supported by the chassis and upon which crop material is deposited, a reciprocating drive operably coupled to the separation frame to reciprocate the separation frame, a control system, a sensor programmed to produce a signal indicative of a tilt of the chassis relative to a gravitational direction, and programmed to provide the signal to the control system, and an adjustable link operably coupled between the separation frame and the chassis to adjust a pivot point of the separation frame. The control system is programmed to determine a change in tilt of the chassis based on the signal from the sensor. The controller is programmed to adjust the adjustable link to modify the pivot point of the separation frame in response to the change in tilt of the chassis.

Harvester separation frame orientation adjustment

A harvester may include a chassis, a first separation frame movably supported by the chassis and upon which crop material is deposited, a second separation frame movably supported by the chassis and upon which the crop material is deposited; a reciprocating drive operably coupled to the separation frame to reciprocate the separation frame and an adjustable link operably coupled between the separation frame and the chassis. The adjustable link facilitates adjustment of an orientation of the first separation frame independent of an orientation of the second separation frame without altering a reciprocation stroke distance.

A first aspect of the invention includes a multi-stage gas compressor having a central cam with a plurality of pistons operably connected to and radially extending from the central cam. The cam follower assemblies each include a roller element connected to a roller bracket which rides within and along a guide channel defines by facing grooves formed in housing end plates.
