Preferably each conditioning device is a brush having a multiplicity of stiff, resilient, elongated elements which are yieldable in more than one plane in response to engagement by the crop by bending of the elements. One brush may form a rotary conveying device for conveying crop through the passage, and another brush may accelerate or retard the crop relative to the first brush. The second brush may be stationary or may be another rotary brush. The conditioning apparatus may be mobile or stationary, and when mobile may include cutting means for cutting crop to be conditioned.

Abstract: The windrower, which may be of the mower or mower-conditioner type, is provided with a double windrowing attachment at the rear thereof which may be lowered into a double windrowing mode or raised into a non-operative position for single windrowing. Severed crops are converged centrally of the machine from opposite sides of the cutting path taken by the machine so as to be discharged onto the ground in a single, centrally disposed windrow when the attachment is in its raised position. Actuation of the hydraulic circuitry associated with the attachment to lower the same into its operating position during a next pass around the field causes a conveyor of the attachment to intercept the centrally and rearwardly discharged crop so as to instead divert and convey the same to a laterally outboard position in order that the windrow of that crop cutting pass will be laid adjacently alongside of the previously formed single windrow for the next preceding pass.

Abstract: A stalk harvester comprises a mobile frame on which is mounted a deflector for engaging and bending upper portions of standing stalks forwardly. A cutter cuts the bent stalks at their base. A pair of generally rotary stalk feeding members are disposed behind the deflector and are mounted for rotation about generally upright axes. These rotary feeding members form a generally upright nip therebetween for gripping the lower stalk ends and feeding the stalks rearwardly. A drive mechanism rotates the feeding members to feed the lower stalk ends rearwardly while upper ends thereof are acted upon by the deflector to cause the stalks to travel upwardly within the nip as the stalks travel rearwardly, thereby causing the stalks to approach a horizontal orientation. A plurality of additional pairs of stalk feeding rotary members are inclined relative to vertical by progressively increasing amounts toward the rear so as to accelerate the reorientation of the stalks toward a horizontal inclination.

Abstract: An apparatus for harvesting and windrowing of corn utilizes one or more conveyor units swingably mounted to a corn harvesting implement such as a combine or corn picker and has horizontally moving cutting means carried forwardly of the conveyor units. As the implement moves through a field of standing corn, the cutting means severs the cornstalks as harvesting heads on the implement engage the stalk and strip the corn ears from the stalk. The conveyors receive and transport the severed stalks to a cornstalk discharge location between the conveyor units to create a cornstalk windrow along the path of the traveling implement. Corn plant residue, such as leaves, kernels, ear husks and the like, resulting from husking, are discharged from the implement and guided by deflector plates onto the windrow to be retained there for curing and later pickup.
