Abstract: In one embodiment, a swathboard control system, comprising: a header comprising fore and aft a cutting assembly and a conditioning system; a forming shield assembly; a swathboard located between the conditioning system and the forming shield assembly, the swathboard pivotably adjustable about a transverse axis; a position sensor configured to sense a position of the swathboard; and a computing system operably coupled to the position sensor, the computing system configured to provide an indication of the position of the swathboard based on feedback from the position sensor.

Abstract: In one embodiment, a system, comprising: one or more pairs of oppositely rotatable, laterally extending rolls, wherein for each pair, at least one of the rolls is moveable relative to the other of the rolls; a hydraulic circuit, comprising: a tensioner circuit comprising: for each pair of rolls, one or more pairs of hydraulic cylinders arranged in parallel, each configured to resist movement of the at least one of the rolls at a respective end of the at least one of the rolls; an accumulator arranged in parallel to the hydraulic cylinders; and plural control valves; and a computing system configured to cause the one or more pairs of hydraulic cylinders to adjust the resistance to movement of the at least one of the rolls of the respective pair of rolls by sending signals to one or more of the plural control valves.

Abstract: A windrower has a crop merger attachment with a conveyor configured to receive crop material from a crop conditioning mechanism and direct the crop material to a side of the windrower, the crop merger attachment being mounted for adjusting movement between a lowered and a raised position. The windrower has a swathboard mounted for adjusting movement between a fully raised position in which the crop material passes beneath the swathboard for engagement with the merger attachment and a lowered position in which the crop material down to the ground under the merger attachment under the windrower. A control system automatically adjusts movement of the swathboard when movement of the merger attachment is detected.
