Abstract: A dual-cam linkage system controls the orientation of tines on a reel of a crop harvesting header. The dual-cam linkage system includes a stationary, substantially circular first cam track that has a rotational center that is offset from the rotational axis of the reel. A second cam track is located in a support plate on which a tine-supporting member is mounted. The dual-cam linkage system also includes a pivoting linkage having a crank, an arm. The crank has a first end fixedly attached to the tine-supporting member. The arm has an outer end attached to a second end of the crank. The first cam follower is attached at an inner end of the arm and engages the first cam track. The second cam follower is attached to the arm at a position between the first cam follower and the crank and engages the second cam track.

Abstract: A plastic tine for mounting on a support tube of a harvester reel has a generally C-shaped mounting base that snaps onto the backside of the tube and an elongated finger that projects outwardly and normally downwardly from the mounting base. A generally C-shaped clip, oriented reversely to the mounting base, partially surrounds the front side of the support tube and is connected to one leg of the mounting base in such a manner that a free end of the clip can be swung toward and away from a corresponding opposite leg of the mounting base. Interlocking structure on the free end of the clip and corresponding distal end of the mounting base retains the clip in place against the front side of the support tube when the clip is fully installed. A special guard protectively overlies the free end of the mounting clip when it is locked to the mounting base so as to prevent accidental dislodgment by crop materials and residue during field operations.

Abstract: In one embodiment, a header control method for an agricultural machine, the method comprising receiving, through a graphical user interface, operator input corresponding to a first set point and a second set point for flotation pressures corresponding to independently controllable first and second header portions, respectively; and automatically causing first and second sets of hydraulic valves to increase or decrease pressure to the first or second header portions to meet or at least approximate the first and second set points, the first and second sets each comprising opposing-action hydraulic valves, the causing responsive to sensed pressure at respective first and second accumulators associated with respective first and second float cylinders.
