Abstract: A mounting and dismounting system for a rear-mounted cotton harvester or similar implement which permits the tractor to be removed from under the crop receptacle without utilizing a hoist or other large equipment. By attaching dismounting stands to the rear cross auger frame and to the rear lift frame assembly, the rear basket posts which normally are connected to the tractor axle can be lifted therefrom by extending the hydraulic cylinders connected to the rear lift frame assembly. The front basket support posts are unpinned from the forward frame of the basket, and as the rear basket posts tilt rearwardly, the basket is lifted to provide clearance in the forward direction. The tractor can then be driven out from under the basket. An extension hose is connected to the lift cylinders so that they remain connected to the source of pressure on the tractor as the tractor is driven forwardly.

The beam (46) is of quadrilateral cross section with its rear wall (51) presenting openings (71, 72, 111, 112) beneath the header discharge opening (19) for centering and latching the header (12) to the feeder conveyor housing (13). The top wall (53) of the beam (46) slopes forwardly and downwardly in parallel supporting relation to the rear portion (39) of the header floor (36).

Abstract: A head assembly for a cotton harvesting machine which provides many combinations of row widths and various row harvesting capacities. The head assembly includes a main cross auger frame with row unit support structure which slidably receives a plurality of vertically adjustable row units. The support structure permits simultaneous transverse adjustment of each individual row unit and its associated hydraulic lift cylinder. An extension frame is provided for adding extra row units for increased capacity or accommodating widely spaced rows of cotton. Row units and lift cylinders are freely slidable between the main frame and the extension, and the extension is removable to lessen machine width during transport. The main cross auger frame includes a pair of transversely spaced bearings which journal opposite ends of a main cross auger. An auger extension is attached to a shaft which extends through the extension end bearing to eliminate need for relocating the bearing or providing a telescoping auger.

Abstract: For a cotton harvester, a low profile row unit which is light in weight and which has a removable top panel structure for easy access to the brush rolls and augers. Rows of horizontal bristles mounted on the panel structure close the top of the row unit to prevent detached cotton from being thrown out of the harvesting compartment. A reinforced lower shell assembly maintains sufficient transverse and vertical stability in the row unit structure and together with the top panel structure eliminate need for an upper supporting arch.

Abstract: A jack stand for attachments, such as the feeder house/header combination, to agricultural machines, such as a combine, is disclosed wherein the jack stand includes a supporting plate attachable to the attachment and provided with an arcuate row of holes spaced even radial distances about a pivot and a pair of telescoping leg members, one of which is pivotally connected at one end to the pivot. A bracket, spaced from the pivot at said same radial distance from said pivot as the arcuate row of holes, is affixed to one of the leg members to receive a pin passed through a selected hole of said arcuate row thereof to establish said leg members at a desired angle relative to a supporting surface. One of the leg members includes a row of transverse holes which is alignable with at least one transverse hole in the other leg member to receive a pin therethrough to establish a desired length of said leg members.

Abstract: Most presently known crop harvesting attachment flotation apparatus use a spring to preload the attachment into a floating mode. A problem with this is that, as the attachment is either forced upwardly or intentionally raised, the effectiveness of the spring decreases. This is avoided by a combination of a spring and a fluid operated cylinder acting through pivotal linkage relationships for retaining the attachment in a substantially constant flotation mode during lifting operations and during flotation operations.

Abstract: An adapter frame for mounting a hay head of a forage harvester to a grain combine comprising an upper frame member for attachment to the upper combine frame, a lower frame member for attachment to the lower combine frame, vertical frame members interconnecting the upper and lower frame members, and horizontal attachment rods secured to the respective upper and lower frame members for reception into clevis members on a forage harvester, a threshold member on the lower frame member to bridge the output opening of the forage harvester with the input opening on the combine frame, and a hydraulic operating motor on the forage harvester connected to the hydraulic circuit of the combine.

Abstract: A mechanism for selectively adjusting the cutting angle of a combine header relative to the ground is disclosed wherein a front face member is pivotably mounted to the forward end of the feeder house for rotation about the forward transverse axis of the crop conveyor within the feeder house. Structure is provided to adjustably lock the front face member into one of a plurality of alternative rotated positions. With the disclosed mechanism, the header cutting angle can be adjusted relative to the ground without increasing the distance between the header and the crop conveyor, thereby maintaining the efficiency of the crop conveyor to engage crop material and transport it rearwardly.

Abstract: A header attachment mechanism for a combine is disclosed wherein a front face member is rotatably attached to the forward end of the feeder house for movement in a fore-and-aft direction and a cradle assembly is pivotally attached to the front face member for rotation generally about the line of travel in a substantially transversely extending plane. By connecting the header to this attachment mechanism, the header can be both adjusted to laterally float relative to the contour of the ground and adjusted to change the cutting angle of the header cutting means relative to the ground through manipulation of the rotation of the cradle assembly and front face member respectively.

Abstract: A lateral float mechanism for a combine header is disclosed wherein the header is detachably mounted to a separate cradle assembly which is centrally pivotably mounted on the feeder house. Structure is provided for locking the header to the cradle assembly for preventing fore-and-aft movement between the cradle assembly and the feeder house and for selectively controlling the extent of pivotal movement of the cradle assembly.
