Abstract: A crop harvesting machine with a cutter bar on a header frame has a height control system which uses depending sensor fingers arranged in contact with the ground so as to measure a height of the cutter bar above the ground. The sensor fingers are controllably retractable under actuation from an operator in the cab or automatically in response to prescribed conditions being met. The actuator used in retracting the sensor fingers can also be used to adjustably control ground pressure of the sensor fingers in the deployed position of the sensor fingers engaging the ground. The header height is adjusted using laterally spaced apart hydraulic linkages which can be operated at different elevations relative to one another responsive to different height signals relating height of opposing ends of the header frame relative to the ground to also control tilt of the header relative to the harvester frame.

Abstract: A conditioner assembly in an agricultural implement for conditioning cut crop material includes a top roll and a bottom roll rotatably supported by a pair of lateral side walls. The top roll is arranged relative to the bottom roll to define a roll gap therebetween for conditioning the cut crop material as the cut crop material passes therethrough. A stabilizing link extends between each of the lateral side walls and the top roll for pivotally coupling the top roll to the conditioner frame, and an adjustment mechanism extends between each of the lateral side walls and the top roll. The adjustment mechanism is selectively and remotely actuatable to automatically pivot the top roll toward and away from the bottom roll, thereby decreasing and increasing the roll gap for optimally conditioning different types and volumes of cut crop material received by the agricultural implement.

Abstract: A draper header is attached to a harvesting machine by an adapter including a bottom feed draper and an upper feed roller driven by a coupling from an output of the machine rotatable about an axis parallel to the forward direction and a right angle gearbox. The feed roller is mounted at each end allowing independent up and down floating movement of the ends and there is provided a mechanical linkage using two chains and an idler shaft between the output shaft of the gear box an input shaft of the roller with a universal coupling therebetween. The gear box is located at least partly underneath the discharge opening and underneath the feed roller, rearwardly of the rear guide roller of the feed draper, rearwardly of the axis of rotation of the feed roller and underneath a feed pan which is inclined upwardly and rearwardly over the gear box.

Abstract: A row crop header for harvesting crop in a field comprises a header frame having a center section and a pair of side wing sections operatively coupled to the center section. An upper link is pivotally coupled between the center section and each one of the side wing sections adjacent the top portion thereof. A lower link is pivotally coupled between the center section and each one of the side wing sections adjacent the bottom portion thereof. The upper links and lower links provide independent pivotal movement of the side wing sections relative to the center section to contour to the surface of the field of crops to be harvested. An automatic float system is operatively coupled between the center section and each one of the side wing sections to adjust the weight of the side wing sections on the surface of the field and allow the side wing sections to float relative to the center section.

Abstract: A drawbar hitch assembly for coupling to a drawbar to pull an agricultural implement includes a pair of locking wedges mounted between a first and a second hitch plate. Each locking wedge is slidably engaged with an inwardly-facing ramp of the second hitch plate for movement between a locked position adapted to cradle the drawbar therebetween and an unlocked position spaced apart and adapted to be released from the drawbar. A plurality of fasteners releasably couple the first and second hitch plates. The fasteners are tightened to move the second hitch plate in a first direction, thereby urging the locking wedges to the locked position to secure the drawbar hitch assembly to the drawbar. The fasteners may also be loosened to move the second hitch plate in an opposite second direction, thereby returning the locking wedges to the unlocked position to remove the drawbar hitch assembly from the drawbar.

Abstract: In a rotary mower having ten generally horizontal cutter disks forming a total cutting length along the cutter bar of 16 feet, the discharge opening containing the parallel conditioner rolls and a parallel transfer roll has a width of at least 125 inches. This allows a first outermost one of the ten disks and approximately one half of the next adjacent disk to be mounted on the cutter bar outwardly of the discharge opening. A convergence system then includes only first and second impellers with the first impeller mounted on the first disk for rotation therewith and the second impeller mounted on an upper support above the impeller so that the second impeller hangs downwardly toward the second disk for contacting the cut crop and mounted immediately adjacent with the second impeller having a peripheral edge located at or immediately adjacent the vertical plane of the side of the discharge opening.
