Abstract: The cutter implement may include a housing, a cutter, and a curtain. The housing has a forward end for engaging the crop material when moving in a direction of operation. The housing at least partially defines a cutting region disposed at the forward end. The cutter is coupled to the housing and can cut the crop material in the cutting region. The curtain is coupled to the forward end of the housing and is positioned forward of the cutter relative to the direction of operation for engaging and leaning the crop material upstream of the cutter. The curtain includes a stiffness control feature operable to control a vertical stiffness of the curtain to provide a variable vertical stiffness that increases with an increase in a bend angle of the curtain rearward relative to the direction of operation.

Abstract: Method and apparatus for controlling the height of a header for use with an agricultural harvester. The header height is controlled by receiving orientation values from a first set of sensors representing orientation of respective support arms of the header, receiving height values from a second set of sensors representing height of the respective support arms with respect to ground, combining the height values and orientation values for each support arm to create a respective multi-sensor value, and controlling the position of the header with respect to the agricultural harvester responsive the multi-sensor value.

Abstract: A reel for a harvesting header has a tine paddle mounted to a tine so as to engage the crop materials as the tine rakes through the crop materials. The tine paddle has a collar portion for at least partially wrapping around a tine tube to which the tine is mounted and an elongate plate member with a distal end spaced inwardly from the outer finger tip of the tine to which the at least one paddle is mounted. One side of the plate member has first and second detents arranged to partially wrap around and engage the finger to hold the tine paddle on the tine. Each detent has an inwardly extending catch that is received in a notch in a side portion of the finger.
