摘要： A header for an agricultural machine including a support structure, a header frame, a floating cutterbar assembly, and a spring. The support structure may be adapted to mount the header to the agricultural machine. The header frame is pivotally coupled to the support structure. The floating cutterbar assembly is operatively coupled to the header frame and pivotally coupled to the support structure. The floating cutterbar assembly is moveable between a first position and a second position. The spring is coupled between the header frame and the floating cutterbar assembly for reducing a ground contact force on the cutterbar.

摘要： A system is provided for controlling a grain cart relative to a grain truck. The grain cart includes a grain tank and an unload auger configured to transfer crop material out of the grain tank. The grain truck includes a truck box extending from a first end to a second end. The truck box includes a top edge extending around the top of the truck box. The system comprises a ranging device and a controller. The ranging device is configured to identify a distance to the top edge of the truck box and identify a distance to an area in the truck box. The controller is configured to determine a position of the grain cart relative to the grain truck, and determine whether the grain cart is positioned near the first end of the truck box. If the controller determines that the grain cart is positioned near the first end of the truck box, the controller is configured to determine a fill level in the area based on the distance to the top edge of the truck box and the distance to the area in the truck box, determine whether the fill level exceeds a threshold, and if the controller determines that the fill level does not exceed the threshold, the controller is configured to start the unload auger.

摘要： A method of navigating an agricultural implement through a field in an operative direction as it is being towed by a tractor. The method comprises providing the implement with a main mounting assembly, which is mountable to the tractor and has a stationary main beam, and a toolbar movably supported on the main beam in a lateral position so as to be shiftable laterally relative to the operative direction to align the toolbar relative to crop rows, the toolbar including row units configured to pass between crop rows; obtaining an image of the field with a camera; segmenting the image to identify a plurality of the crop rows extending in the operative direction within a field of vision of the camera; and adjusting the lateral position of the toolbar to maintain the row units between the plurality of crop rows while avoiding damage to the crops.

摘要： Crop is carried into a feed opening of a harvester by two side drapers, two rear back sheets defining an opening between inner edges, a central feed draper and a roller with end flight portions and a central finger portion located above the feed draper. In this geometry, a bottom tangent to the flight portions has a position which is at a height below the rear edge of the side drapers. The roller axis of the feed roller is behind the rear edge of the side drapers and behind a common plane containing the back sheets. The inner guide roller of each of the first and second side drapers is located inwardly of the inner edge of the first back sheet and inwardly of an outer end of the end flight portion. A forward most tangent to the flight portions projects forward of or proud of the common back sheet plane.

摘要： 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.

摘要： 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.

摘要： A crop harvesting header having a frame mounted on a propulsion vehicle has a cutter bar carrying a sickle knife and a draper transport. The draper is guided at its front edge by a longitudinally extending rail mounted on the frame for movement therewith. The cutter bar is mounted on the frame at spaced positions by spring blades attached to a fixed beam at the rear which allow up and down flexing movement of the cutter bar relative to the draper engagement member. At the center discharge the cutter bar is carried on shorter blades which are carried on a beam in front of the front draper roller. The small amount of flexing of the cutter bar combines with a balanced three piece header frame to provide effective ground following.

摘要： In a crop harvesting header with a center section and two wings where each wing is pivotal relative to the center section about a pivot axis extending in a generally forward direction which includes a balance system to maintain a balanced ground force distribution across the width of the header there is provided an automatic adjustment system for maintaining proper balance. The system includes a sensor which repeatedly, over a time period during which the header is operating, detects data relating to the positions, distance from the ground or weight applied to the ground of each wing frame portion, a processor arranged in response to the sensed data to calculate a value representative of the positions and an adjustment mechanism for effecting an adjustment of the balance system in response to the value.

摘要： A header is supported by a pair of hydraulic float cylinders, where a float pressure to the cylinders is directly controlled by an electronic control supplying a variable control signal to a PPRR valve arrangement to maintain the float pressure at a predetermined value. At the set pressure a predetermined lifting force is provided to the header. A position sensor is used to generate an indication of movement and/or acceleration and/or velocity. The electronic control is arranged, in response to changes in the sensor signal, to temporarily change the control signal to vary the lifting force and thus change the dynamic response of the hydraulic float cylinder. A lift force greater than that required to lift the header can be provided by a lift cylinder and can be opposed in a controlled manner to apply a controlled downforce by the back of the same cylinder or by a separate component.

摘要： A reel includes a plurality of bats and an end shield plate mounted on the end of the reel at the crop divider which has a peripheral edge radially inward of an outer tip of the fingers with an apex at each of the bats and portions which are recessed from a straight line joining the apexes. Each of the endmost fingers of the bats has a base which is axially inside the end plate and is bent longitudinally of the reel to define an outer tip which is axially spaced from the base to a position beyond the radial plane of the end plate. A plurality of molded paddle blades are mounted to project outwardly from the end surface to clear crop away from the space between the outer face of the end plate and the divider.
