Abstract: A belt pickup header for an agricultural harvesting machine includes a frame having opposite ends, a belt pickup carried by the frame, and a pair of suspension arms carrying the belt pickup. Each suspension arm is pivotally coupled with a respective frame end. A pair of compression springs are each positioned between a respective suspension arm and corresponding frame end. Each spring vertically supports a respective suspension arm. A pair of fluid shocks are each interconnected between a respective suspension arm and corresponding frame end. Each fluid shock damps movement of the corresponding suspension arm.

Abstract: An endless crop conveying belt loop has a bolted connection including belt material having a top and bottom surface and first and second opposed ends. Each of the two opposed ends having complementary patterns of half wave shapes. Each pattern has a plurality of longitudinal extensions alternating with transverse straight edges. The longitudinal extensions are interwoven between respective extensions of the complementary pattern on the opposed end so that the longitudinal extensions of both opposed ends overlap the top surface of the opposed end and the transverse straight edges of both opposed ends are generally aligned. A staggered array of fasteners secures the two opposed ends together.

Abstract: A hold down mechanism controlling the top mat of crop material on a pickup belt platform includes a pair of support arms pivotally mounted on the opposite sides of the frame and extending longitudinally parallel to the rotatable pickup belt. A transverse cross member extends between the two support arms. The cross member has a tubular cross section and a transverse array of through holes, each through hole having a first opening and a diametrically opposite second opening in the tubular cross member, wherein the first opening is larger than the second opening. A plurality of hold down fingers are provided. Each finger has a flexible rod portion extending from and secured in a base portion. The base portion has a shoulder opposite the secured rod portion and a retaining portion extending from the shoulder opposite to the rod portion. A plurality of releasable retainers are provided.

Abstract: A rotor, in an agricultural harvester crop processing unit, comprising a drum to which crop processing elements for an infeed section and a threshing section are affixed. The drum comprises a rearward cylindrical portion and a forwardly extending frusto-conical portion. The frusto-conical portion is divided into an aft-region adjacent to the rearward cylindrical portion of the drum, and a fore-region. The infeed section has at least one infeed element located on the fore-region of the frusto-conical portion of the drum. The crop processing section has at least one crop processing element located on the aft-region of the frusto-conical portion of the drum.
