An agricultural vehicle including a chassis and a threshing system supported by the chassis. The threshing system includes a rotor, a front concave located at a distance radially away from the rotor and at least partially surrounding the rotor, and an infeed ramp connected to the front concave. The infeed ramp is located at a distance radially away from the rotor and has a plurality of slots therein. The threshing system also includes a support member positioned underneath the infeed ramp and a plurality of vanes connected to the support member. Each vane extends through a respective slot of the plurality of slots and is located at a distance radially away from the rotor. The vanes are configured for contacting and directing the crop material rearwardly towards the front concave.

An agricultural vehicle crop feeder system having housings defining a crop passage, a conveyor assembly, a rotor, a guide plate, and one or more guide vanes extending from the guide plate. The conveyor assembly propels crop material along a feeder flow direction to the rotor. The rotor has inlet vanes that receive the crop material in a receiving region located below the rotor's axis. The leading edges of the rotor inlet vanes travel towards the receiving region on a first transverse side of the rotor axis and away from the receiving region on a second transverse side of the rotor axis. The guide plate is adjacent the receiving region. The guide vane extends into the crop passage on the first side of the rotor axis, and angled relative to the flow direction with its trailing edge closer to the first rotor axis, in the transverse direction, than the leading edge.

In one aspect, a system for adjusting the conveyor belt tension force within an agricultural harvester may include a conveyor having a first roller, a second roller spaced apart from the first roller, and a conveyor belt configured to engage the first and second rollers. The system may also include a tensioner assembly having a ratcheting mechanism configured to selectively adjust a position of the first roller relative to the second roller to adjust a tension force exerted on the conveyor belt.

A harvester feeder may include a housing forming a crop passage having a width and a conveyor supported by the housing to extend above crops being conveyed along the crop passage. The conveyor may include a frame, at least one forward tensioner, at least one drive sprocket and at least one belt about the forward tensioner and the drive sprocket. In one implementation, the at least one belt forms a substantially uninterrupted crop engaging belt surface extending across a majority of the width. In one implementation, each belt has an upper portion and a lower portion with the lower portion being adjacent the crop passage, wherein a crop massager extends between the upper portion and the lower portion and resume only presses the lower portion of the continuous belt towards the crop passage.

A faceplate sub-assembly for an agricultural vehicle includes a faceplate and at least one biasing element. The faceplate is configured to be connected between (i) a feederhouse defining an inlet opening through which crop material is delivered for processing by the agricultural vehicle, and (ii) a header of the agricultural vehicle. The faceplate is configured to be pivotably mounted to the feederhouse such that the faceplate is configured for lateral tilting relative to the feederhouse. The at least one biasing element has one end connected to the faceplate and another end that is configured to be connected to the feederhouse for reducing a friction force at the interface between the faceplate and the feederhouse to accommodate lateral tilting of the faceplate.

A reinforced feeder housing for an agricultural machine includes a housing body having a top surface, a bottom surface, and two opposing side surfaces each extending between the top and bottom surfaces. The housing body includes a front opening through which crop material is directed into the feeder housing from a header of the agricultural machine, and a rear opening that is substantially opposite the front opening through which crop is expelled from the feeder housing and is delivered to a threshing mechanism of the agricultural machine. Various panels of the housing body are reinforced to improve the structural integrity of the feeder housing and prevent damage to the welds in the housing body.
