Abstract: A method and apparatus for mounting concaves in an axial flow combine having the threshing and separating rotor extending in a longitudinal direction is disclosed wherein the concaves can be mounted on its adjustable mounting frame through the side of the combine. A pair of longitudinally spaced concave frame members are provided with yokes engageable with longitudinally extending mounting pins affixed to the mounting frame. Support plates carried by the mounting frame can be utilized to support the weight of the concave during the mounting procedure. Retaining links mounted on the mounting pins in conjunction with the concave yokes are connected to the concave frame members to retain the concave on the mounting pins during operation of the combine.

Abstract: The problem of adjusting the relative position of concaves and rotors is accomplished without shims by providing adjustable members engaged with sidewalls of a combine and threaded into opposite ends of a concave support member.

Abstract: The disclosure is directed to a combine with a unique sealing arrangement between the pivotable feeder housing and the inlet opening. The rearward portion of the feeder housing, extending into the inlet opening, includes spaced apart arcuate smooth edge plates which mate with, but do not contact, sealing blocks affixed to the inside vertical side edges of the inlet opening. The feeder housing further includes axially aligned pivot arms which extend away therefrom to engage a pair of support yokes which permit the housing to pivot vertically. The pivot arms and the edge plates have the same central axis so that pivoting of the feeder housing does not interfere with the sealing block/edge plate relationship.

Abstract: An agricultural harvester having a header pivotally connected to the forward end of said harvester and said header having a flexible floating cutterbar on the forward lower edge thereof and a rotary reel mounted for automatically adjustable movement toward and from said cutterbar by power means to prevent accidental contact between the same. The harvester also includes power means to elevate the header to enable the same to effect desired spacing from the surface of a field when the contour is such as to require the same. Sensing means responsive to the surface of a field control the operation of the respective power means for said reel and header automatically.
