Abstract: An axial flow combine harvester feed plate for directing crop material from a conveyor into the lower forward portion of an axial flow rotor housing. The feed plate includes surfaces that reduce the overall width of a mat of crop material entering the rotor housing and a surface that guides material upwardly and rearwardly. The surface of the feed plate that guides crop material upwardly and rearwardly directs the mat of crop material into the rotor housing hear the front of the axial flow rotor on one side of the rotor housing. On the other side of the rotor housing, crop material enters the housing some distance rearwardly from the front of the axial flow rotor. This results in a band of crop material engaging the rotor in the rotor housing.

Abstract: The stone trap for a combine harvester 10 includes an elevator to the cylinder 26, a beater assembly 40 rotatably mounted in the elevator and an opening 72 in the floor 38 of the elevator below the opening 72. A box 78 is mounted under the floor 38 to receive material that passes through the opening. Spring steel fingers 94 are bolted to the floor 38 at the forward edge 74 of the opening 72. The free ends of the fingers extend across the opening 72. The upper portion 104 of the rear wall 82 is a support to limit vertical movement of the free ends of the spring steel fingers 94. In operation, the free ends of the spring steel fingers 94 move to the side for the passage of stones driven into the box 78 by the beater assembly 40 and then spring back to hold stones in the box 78.

Abstract: The agricultural harvester 10 cooling system includes a heat exchanger 38 for cooling an internal combustion engine 32 and a heat exchanger air cleaner assembly 36. The heat exchanger air cleaner assembly has a fixed screen 62 adjacent the heat exchanger 32 which forms one wall of a large box 45. Channel members 64 and 66 and flat bars 68 hold the fixed screen 62 in a plane and form a plurality of pie-shaped compartments. The air cutoff plate 78 on rotatable shaft 72 closes the pie-shaped compartments and substantially blocks the flow of air through the fixed screen 62. A suction pipe 84 adjacent the fixed screen 62 and inside the large box 45 rotates with the rotatable shaft 72 directly across the fixed screen from the cutoff plate 78. The suction pipe 84 is connected to the intake of a centrifugal blower 118 by a vacuum pipe 96.
