Quick attachment of crop handling headers to harvesters employs one or more wedge locks, utilizing the mechanical forces thereof to, in turn, tightly and firmly wedge an elongated tongue portion of the header into mating relationship with a header-supporting channel member on the harvester. For fast and easy attachment and release, reciprocable wedge-like latches are jammed into corresponding keepers with progressively increased tightness through use of reciprocable latch shifters readily accessible to the operator at ground level exteriorly of the ends of the header support. An exceptionally strong joint is effected as the latches and their keepers jam the tongue into the channel member.

The knife is normally clamped tightly against a supporting arm by a retaining bolt, but when the bolt is sufficiently loosened, the bolt itself and the knife through which it passes may be forced radially inwardly or outwardly by shifting a transversely reciprocable slide plate in the appropriate direction along its path of travel. An oblique slot in the slide plate receives the bolt and pushes it in the selected adjusting direction as the slot is displaced transversely by shifting of the plate. A pair of counter-acting set screws serve as means for shifting the plate and for releasably retaining the same in a selected position. A long key on the slide plate slidably fits into a mating key way on the supporting arm to guide the plate in its transverse movement, and because the key extends transversely of the path of in-and-out adjusting travel of the knife, it helps absorb and resist radial loading on the knife which occurs during the cutting operation.

Large round bales are picked up in the field by forcing the inclined bed of the machine beneath the bales while simultaneously drawing them onto the bed with a conveyor chain. With the bed leveled, the bales can be transported end-to-end to a feeding location and, while still moving, thereupon successively transferred laterally to an outboard disintegrating unit which drops the material in a continuous stream to the ground or into a feed bunk. After each lateral transfer and outboard disintegration, the bales are advanced along the bed until the next succeeding bale is in position for processing. Alternative forms of lateral transfer apparatus include a lift that swings a bale upwardly off the bed and into the disintegrating unit, a ramp that cocks the bale toward the disintegrating unit in position for an overhead door to sweep the cocked bale into the unit, and an overhead feeder that reaches across the bed and draws the bale into the unit.
