OPERATION
Cam Position 2, Reel Position 3 or 4 is the recommended
starting position for most crops and conditions.
• This setting gives a fingertip speed approximately 20%
faster than the reel speed.
• If crops tend to stall on the cutterbar with the reel in a
forward position, the cam setting should be increased to
push the crop past the rear edge of the cutterbar.
• If the crop getting fluffed, or the flow across the drapers
is disrupted, the cam setting should be decreased.

faster than the reel speed.
