The device relates to a pivoting forearm rest positioned behind the hand controls of a skid steer loader. The device consists of a tube with an angled portion inserted into a ‘J’ shaped support bracket. The bracket is affixed to the cab sidewall and may be vertically adjusted. The rotation of the tube is adjusted by a tension bolt and shim within the support bracket. The tube has a pin seated within a tube slot in the support bracket which allows the tube to rotate 180 degrees. A portion of the tube and the support bracket are covered in padding.

A tying mechanism on a baler having a bale forming chamber incorporates an improvement for removing end play between the components of the tying mechanism. The tying mechanism includes an elongated drive shaft and a plurality of side-by-side units mounted along the shaft and operable to carry out tying of strands of material that band a bale being formed in the bale chamber. The tying units are movable axially along the shaft for adjusting them to predetermined operational positions relative to one another. The improvement relates to a pair of annular adjustment cams being mounted about and releasably secured to the shaft between the units. The cams of each pair thereof engage one another and are individually rotatable, upon release of the securement thereof to the shaft, for movement to various angular positions relative to each other about the shaft to vary the width of the space occupied by the pair of cams and thereby adjust the units relative to one another and maintain the same at the predetermined positions along the shaft.

Method and apparatus for transporting a crop harvesting header, attachable to a combine to sever standing crop and initiate the crop harvesting process, is disclosed wherein the apparatus is mounted on and carried with the header in a retracted position during the normal crop harvesting process until it is desirable to transport the header. A first wheel assembly is pivotally movable into a ground engaging position to support a part of the weight of the header above the ground for transport. A second wheel assembly is removed from a mounting bracket on the back of the header and is connected to the cutterbar in longitudinal alignment with the first wheel assembly. An axle is provided to interconnect the first and second wheel assemblies to provide a stable wheeled undercarriage for the transport of the header. A tongue is extracted from within the frame of the header for connection to the rearward end of the combine, resulting in the header being towed as its own carrier in a transverse attitude behind the combine.

A stabilization system used with a crop harvesting header includes a frame carrying a belt to deliver a crop to the header. The frame is independently movable between a first angle between the frame and the header and a second angle between the frame and the header. A member has an inside surface connectable in substantially non-rotational contact to a first structure of one of the frame or the header, and an outside surface connectable in substantially non-rotational contact to a second structure of the other of the frame or the header. In response to rotational movement of the first structure in substantially non-rotational contact with the inside surface, rotational movement of the first structure occurring with respect to the second structure in substantially non-rotational contact with the outside surface, the member provides a stabilizing torsional force between the frame and the header between the first and second angles.

A bale accumulator and optional caboose are controlled by a microprocessor-based control circuit associated with and controlling the baler which pulls the bale accumulator. The control circuit monitors bale switches actuated by the presence of bales on four tables, two switches indicating the position of a bale push bar, and three table switches indicating when individual ones of three of the tables are latched or released for dumping bales therefrom. An operator's panel provides a visual display of the status of the bale accumulator and includes switches which may be actuated by the operator. In response to the switches on the bale accumulator the control circuit controls the push bar to move bales from a center table onto a left or right table at the sides of the center table, or inhibits movement of the push bar so that a succeeding bale ejected from the baler pushes a bale on the center table onto a trailing fourth table. In response to actuation of a dump switch the control circuit determines which tables should be unlatched to dump a bale therefrom, and energizes a motor or motors to unlatch the tables as determined by the control circuit. All operations of the bale accumulator are automatic except for operator actuation of the dump switches.

A basic frame for a crop harvesting header which is attachable to a combine to sever standing crop and initiate the crop harvesting process is disclosed wherein the same frame can be utilized in the construction of both rigid and flexible headers. A connection member is provided for each attachment rib interconnecting the frame and the cutterbar, such that the attachment rib can be either pivotally connected to the frame to provide a flexible header or rigidly attached to the frame to provide a rigid header. Each connection member permits a rigidly attached rib to be vertically positionally adjusted to provide proper alignment of the cutterbar across the entire width of the header. The header frame includes a hat-shaped member corresponding to each of the connection members within which the attachment ribs can be nested.

An agricultural baler for picking up crop material and forming it into a rectangular shaped package, having a bale density control system. The baler has a bale case including four wall members forming a generally rectangular opening, at least one of which wall members includes a tension rail movably mounted to vary the cross sectional area of the rectangular opening. The baler also has a hydraulic control arrangement including a hydraulic cylinder operable for changing the position of the tension rail, a pressure control valve comprising a variable relief valve, and a hydraulic circuit for coupling the hydraulic cylinder to the pressure control valve. The relief valve is selectively controlled by an electronic controller.

A round baler having a frame with opposing side walls, conveying apparatus including a series of inwardly facing moving surfaces defining a baling chamber for forming cylindrical bales of crop material and a feeder for feeding crop material into the chamber. Rotatable transverse rollers are mounted between the opposing side walls of the frame for operatively supporting the conveying apparatus, and a journal assembly having a bearing arrangement for mounting the rollers. The bearing arrangement includes a generally cylindrical stationary first race and a concentrically disposed generally cylindrical rotatable second race between which races a bearing cavity is formed for seating a series of bearings housed between said first and second races. A unique shield assembly encloses the cavity and prevents the intrusion of unwanted debris.

A tension control device is disclosed which is particularly well suited to chain drive systems subjected to cyclic forces. The device includes a tension-setting adjustment mechanism affixed to a pivoted mounting plate and an arm means pivoted at one end, at the same location as said mounting plate, supporting a sprocket for engagement with the chain. Biasing and stop means coact with the mounting plate and the arm means to urge them apart and limit the maximum and minimum separation therebetween.
