Recommended settings
Optimizing the header requires adjustments to the following settings:
• Move the reel fore-aft cylinders to the alternate aft location. Refer to Repositioning Fore-Aft Cylinders, page 85.
• Adjust the reel fore-aft position. Refer to Adjusting Reel Fore-Aft Position, page 85.
• Adjust the reel height so the fingers just engage the crop. Refer to 3.7.9 Reel Height, page 84.
• Set the reel cam to position one. Refer to Adjusting Reel Cam, page 94.
• Set the reel speed equal to the ground speed and increase as required. Refer to 3.7.5 Reel Speed, page 79.
• Decrease the feed auger spring tension. Refer to Checking and Adjusting Feed Auger Springs, page 49.
• Set the side draper speed to position nine on CA25 control. Refer to 3.7.7 Draper Speed, page 80.
Checking and Adjusting Feed Auger Springs
The feed auger has an adjustable spring tensioning system that allows the auger to float on top of the crop instead
of crushing and damaging it. The factory-set tension is adequate for most crop conditions.
DANGER
To avoid bodily injury or death from unexpected start-up of machine, always stop engine and remove key
