OPERATION

 

 

 

CORNERING

 

 

Because of the long turning radius of the larger windrowers (especially 36 ft.), use the cornering procedure 

illustrated. 

 

This procedure will prevent swath disturbance and grain loss caused by tractor and/or windrower tires. In 

addition, the technique should result in a corner that can be picked up by your combine without extra turning. 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

  

 

 

FIELD LIGHT

 

 

The field light (A) is positioned to shine on the 

windrow when cutting after dark. 

 

CAUTION: Do not turn work light on 

when transporting the windrower on 

roadways. Other drivers may be 

confused by its position.
