Windrower implement with merger attachment

A windrower implement comprising:

• a frame extending along a central longitudinal axis between a forward end and a rearward end relative to a direction of travel during operation;
• an implement head attached to the frame proximate the forward end thereof, wherein the implement head is operable to cut standing crop material and discharge cut crop material in a rearward direction along the central longitudinal axis;
• a merger attachment coupled to the frame rearward of the implement head, wherein the merger attachment includes a conveyor positioned relative to the implement head to receive discharged crop material from the implement head and convey the crop material to a laterally offset location on a discharge side of the frame relative to the central longitudinal axis;
• an image sensor positioned to capture an image of a windrow laterally offset from the central longitudinal axis on the discharge side of the frame;
• a merger controller disposed in communication with the image sensor and the merger attachment, the merger controller having a processor and a memory having a merger control algorithm stored thereon, wherein the processor is operable to execute the merger control algorithm to:
• capture an image of the windrow with the image sensor;
• identify an edge of the windrow in the captured image;
• determine a location of the edge of the windrow relative to the conveyor;
• and
• control a current speed of the conveyor based on the location of the edge of the windrow, whereby the cut crop material discharged from the conveyor is deposited along the edge of the windrow.
