Disclosed is a lifting assembly for a crop severing assembly forwardly carried by a tractor having a frame and front a frame and an axle assembly carrying front wheel assemblies. The crop severing assembly has a forward end and a rear end, and includes a pair of bracket assemblies located at the forward end and atop the crop severing assembly. A pair of lift cylinder assemblies each have a lower end and a top end. The lift cylinder lower ends are located at either side of the rear end of the crop severing assembly to bottom brackets extending from the tractor frame forward of the tractor axle assembly and are attached between each cylinder lower end and each cylinder top end to trunnions carried by the crop severing bracket assemblies for pivotally raising and lowering of the forward end of the crop severing assembly.

An agricultural harvester includes a threshing system having a rotor, a rotor cage surrounding the rotor and including a concave, and a transition cone defining an infeed to the rotor cage. The transition cone has a conical inner surface extending in an axial direction between an upstream end and a downstream end of the cone. A vane is mounted to the conical inner surface of the transition cone. The vane protrudes radially from the conical inner surface, and extends along an axial direction between the upstream end and the downstream end. The vane has a body extending along an axis and a cross-sectional shape that is not constant along the axis.

A combine harvester is provided with: a threshing device that performs a threshing process of threshing a crop; a grain tank that stores grain obtained by the threshing process; a grain discharging device that discharges grain to be stored in the grain tank to the outside of the vehicle body; a travel driving device that drives travel of the vehicle body; and an engine that serves as a power source. The combine harvester includes a first relay shaft to which power is transmitted from an output shaft of the engine, and the power of the engine is transmitted from the first relay shaft to the grain discharging device and the travel driving device in a branched manner.

A combine harvester including one or two axial flow crop processors each with a rotor mounted for rotation inside a rotor housing that is arranged substantially longitudinally with respect to the harvester. A feed beater is mounted for rotation on a substantially transverse axis and serves to tangentially impel crop material into the crop processor(s). A drive system is provided for driving the rotor and the feed beater. A drive connection is provided between the rotor and the feed beater and includes a gear that is keyed to a rotor shaft of the rotor in front of a rotor drum.

An agricultural vehicle feeder assembly having: a feeder housing, a shaft mounted to rotate relative to the feeder housing, first and second rotary drives mounted to rotate with the shaft at a first and second axial positions along the shaft, and an anti-wrap cover assembly extending an entire distance from the first rotary drive to the second rotary drive and at least partially surrounding the first rotary drive, the second rotary drive, and the shaft between the first rotary drive and the second rotary drive. The anti-wrap cover assembly is rotatably mounted the first rotary drive, the second rotary drive and/or the shaft. A connector joins the feeder housing to the anti-wrap cover assembly. The connector is configured to allow the anti-wrap cover assembly to move through a predetermined limited range of motion relative to the feeder housing.

A feeder housing for an agricultural harvester includes: a housing; a conveyor system disposed in the housing, the conveyor system including a drive shaft, at least one drive loop coupled to the drive shaft such that rotation of the drive shaft causes rotation of the at least one drive loop, and a plurality of crop grabbers coupled to the at least one drive loop; a rock beater disposed in the housing and including a rotatable beater roll and at least one fin carried by the beater roll; and a motor coupled to the beater roll and configured to rotate the beater roll. The motor is an electrically powered motor or a hydraulically powered motor. The motor is coupled to the beater roll such that the motor is configured to rotate the beater roll without rotating the drive shaft.

A combine includes a feeder housing that include a movable cradle frame at the front, configured to receive a header, so that a controlled movement of the cradle frame may be imparted to the header during a harvesting run. The combine further includes a driveline for driving moving components of the combine header. The driveline includes a belt drive mounted laterally with respect to the feeder housing. The belt drive is configured to transfer a rotation of a first drive axle that is part of the driveline, to a rotation of a second axle to which a drive axle of the header can be coupled. The belt drive includes two pulleys which are maintained in a common plane regardless of movement of the header relative to the feeder housing. The pulleys are rotatably mounted in a longitudinally extendable bridge structure, and are coupled to the first and second axles.

Steps to manufacturing a feed beater for a twin axial-flow crop processor in a combine harvester including cutting a flat state vane element from sheet material and bending along predetermined bend lines before being secured to a rotor core. The vane element includes a transverse vane section parallel to the rotation axis, and a directional vane section having an effective edge that extends at a non-zero angle to the rotation axis.
