Abstract: A grain header has a frame with a cutter bar affixed to the frame. A sub-frame is pivotably coupled to the frame and a mower cutter bar is coupled to the sub-frame. A swather is coupled to the sub-frame and arranged rearward relative to the mower cutter bar. A deflector is disposed between the cutter bar and the mower cutter bar. The deflector is moveable between a raised position in which the deflector permits crop material cut by the mower cutter bar to pass onto the swather, and a lowered position in which the deflector inhibits crop material cut by the mower cutter bar from passing onto the swather.

Abstract: In one embodiment, a method, comprising: in one pass: cutting a first portion of crop with a plurality of knives of a cutter bar of a header coupled to an agricultural machine; conveying the cut first portion to a center of the header; cutting a second portion of the crop during the same pass with a second set of knives of a mower cutter bar coupled to the header; and either chopping the cut second portion or swathing the cut second portion based on a respective position of a swather disposed rearward of the mower cutter bar and a deflector disposed between the cutter bar and the mower cutter bar.
