A draper header for harvesting crops includes a header frame with a middle frame section pivotally coupled between a pair of side wing sections. A cutter bar assembly extends across a front portion of the header frame and is flexible with the side wing sections for cutting the crops to be harvested. A pair of crop pick-up reels are rotatably supported by center and outer reel support arms for engaging the crops to be harvested. A sensing system is operatively coupled to the header frame for detecting when at least one of the side wing sections pivots downwardly relative to the middle frame section. When the sensing system detects that at least one of the side wing sections pivots downwardly past a predetermined pivot angle, a down-stop cylinder is actuated to raise the crop pick-up reels, thereby preventing contact of the crop pick-up reels with the cutter bar assembly.

A draper header includes a draper frame and a reel arm. The reel arm is coupled to a reel and pivotally coupled to the draper frame. The draper header further includes a cutterbar pivotally coupled to the draper frame. The reel arm and the cutterbar are configured to pivot about the draper frame to adjust a side profile aspect ratio of the draper header from a first aspect ratio to a second aspect ratio. A height of the first aspect ratio is less than a height of the second aspect ratio, and a width of the first aspect ratio is greater than a width of the second aspect ratio.

A follower assembly of a cam assembly for a harvester reel including a baffle, a compressible member adjacent the baffle, and a roller spacer adjacent the compressible member. The follower assembly further includes a tubular cam follower housing the roller spacer, and a fastener extending through the tubular cam follower, the roller spacer, the compressible member and the baffle. The resultant follower assembly provides a construction which minimizes peening of the baffle, whereby the fastener maintains its clamp load such that the cam followers maintain engagement with the cam track and the potential for breakage of the fastener is minimized.

A header system for an agricultural harvester includes a first reel section, a second reel section, and a sensor configured to generate data indicative of a parameter related to a crop within a field. The header system also includes a controller configured to receive the data and to control a first actuator to adjust the first reel section independently from the second reel section based on the data as the agricultural harvester travels through the field.

An agricultural system includes a frame, a cutter bar assembly configured to move relative to the frame during an operation of the agricultural system, a reel assembly configured to guide crops to the cutter bar assembly during the operation of the agricultural system, and a controller. The controller is configured to receive feedback indicative of a profile of the cutter bar assembly, set a position boundary of the reel assembly based on the feedback, and block movement of the reel assembly to a position beyond the position boundary of the reel assembly.

A calibration system for an agricultural header includes a controller having a memory and a processor. The processor is configured to receive a first position signal indicative of a first position of a reel arm of the agricultural header, receive a first distance signal indicative of a first distance between the reel arm and a terrain feature, receive a second position signal indicative of a second position of the reel arm, receive a second distance signal indicative of a second distance between the reel arm and the terrain feature, determine a calibration curve having a plurality of offset distances of the reel arm based on the first position, the first distance, the second position, and the second distance, and select an offset distance of the plurality of offset distances based on an operational position of the reel arm and the calibration curve.

A harvesting vehicle includes a header having a cutter bar, a crop transport draper and a reel mounted above the cutter bar to sweep the crop to the draper. The operation of the header is autonomously monitored and controlled to reduce operator loads or to run autonomously by detecting: reel wrapping; differential rates of flow of crop on the header at different locations; where the crop to be cut is at least partly lodged so that stems of the crop are not vertical; the presence of a crop streak of uncut or poorly cut crop behind the cutter bar and/or a band of disturbed soil behind the cutter bar. The detector is arranged to control ground speed, header height, reel height and operation.

An agricultural header having a frame, a first support arm, a second support arm spaced from the first support arm, a reel extending from a first reel end rotatably mounted to the first support arm to a second reel end rotatably mounted to the second support arm, a first actuator operatively connected to the frame and the first support arm and configured to move the first support arm relative to the frame, a second actuator operatively connected to the frame and the second support arm and configured to move the second support arm relative to the frame, and a control system configured to alternately operate the first actuator and the second actuator in repeating alternating incremental steps to thereby move the reel from a first reel position relative to the frame to a second reel position relative to the frame. A combine having such a header is also provided.
