ABSTRACT:
An improved concave extension for use with an arcuate concave cooperable with a threshing and separating rotor in an axial flow combine is disclosed wherein the sub-frame assembly of the concave extension is provided with a mounting clevis rotatably engageable with one of two mounting pins extending from the concave frame members to permit the concave extension to be rotated relative to the concave frame members. The subframe assembly is also provided with a hole therein alignable with a plurality of openings in the respective concave frame members to permit the use of a fastener extending through the hole in one of the aligned openings to fix the position of the concave extension relative to the concave frame members, thereby providing variable configurations of the rub bars on the concave extension relative to the rub bars of the concave. A filler plate is rotatably mounted to the forwardmost concave frame member and positionable relative to both the concave frame member and the concave extension. The concave extension and filler plate are easily positionable and/or removable by manipulation of two bolts interengaging the sub-frame assembly and the respective concave frame members.
