Abstract: A feeder house of an agricultural harvester has lift cylinders that can be locked to reduce the risk of damage due to feeder house twisting due to impacts with the ground.

Abstract: The discharge section of an axially arranged rotary combine is provided with a discharge chute having a ramp on the downward swept side. The ramp is provided with upper and lower metering edges for metering the flow of crop material other than grain from the helical flow to a transverse discharge beater. The floor of the discharge chute is provided with three guide vanes that define specific flow paths of the crop material being expelled by the axial crop processing unit and directing this crop material uniformly across the transverse discharge beater. The upward swept side of the discharge chute is provided with a filler plate for engaging crop material that was not engaged by the vanes to direct this crop material to the upward swept side of the discharge beater.

Abstract: A variable sweep infeed element for a rotary combine is bolted to the infeed section of the rotor drum and extends radially outward therefrom. The element is provided with a forward portion and a rearward portion. The forward portion is the location where the infeed element first contacts the crop mat. The forward portion has a radial section that extending radially outward from the rotor drum and an outermost section is forward swept in the direction of rotor rotation. This forward sweep is most aggressive at the initial feeding point and becomes less aggressive as the forward portion extends longitudinally downstream towards the transition point between the forward portion and the rearward portion. The rearward portion is provided with a radial section extending radially outward from the rotor drum and an outermost.

Abstract: The crop engaging element of the present invention is a hollow structure having a smooth curved convex top portion which terminates in a concave trough before extending into a radially extending lip. The hollow structure is provided with sidewalls and a rear wall. The sidewalls extend upwardly to enclose the sides of the trough. The element is provided with leading and trailing mounting flanges for mounting the element to the exterior surface of a combine rotor.

Abstract: An axial agricultural combine having a single element rotor defining a rotor axis. The rotor is housed in a rotor housing having an infeed section, a threshing section and a separating section. The infeed section of the rotor housing defines a infeed axis, the threshing section of the rotor housing defines a threshing axis and the separating section of the rotor housing defines a separating axis. The infeed axis is parallel to and in line with the rotor axis. The threshing axis is parallel to and offset from the rotor axis. The threshing axis is offset above and downstream from the rotor axis. The separating axis is parallel to and offset from the rotor axis. The separating axis is offset above and downstream from the rotor axis. The separating axis is more offset from the rotor axis than the threshing axis is offset from the rotor axis.
