On-the-go from the tractor seat windrow adjustment

In a windrower having mechanism for conditioning crop material severed from the field and for discharging the conditioned material in a rearwardly directed stream as the windrower moves across the field , the improvement comprising:

• a pair of rearwardly converging windrow forming shields mounted for placement in the path of travel of the stream of conditioned material,
• said forming shields having front ends that are spaced apart substantially the full width of the conditioning mechanism, rear ends that are spaced apart substantially less than the full width of the conditioning mechanism, and elongated deflecting surfaces extending between said front and rear ends for engagement with the stream when the shields are placed in the path of travel of the stream;
• a transverse swathboard between said crop conditioning mechanism and the forming shields along substantially the full width of the conditioning mechanism,
• said swathboard being mounted for adjusting movement between a fully raised position in which the stream of crop material passes beneath the swathboard for engagement with the forming shields to form a windrow on the ground and a fully lowered position in which the stream of crop material is diverted down to the ground ahead of the forming shields to form a swath;
• and
• a remotely operable actuator operably coupled with said swathboard for effecting said adjusting movement of the swathboard on-the-go,
• said actuator being operable to position and retain said swathboard in any one of the number of infinitely variable positions between said fully raised and fully lowered positions.
