If adjustment is required, loosen hardware (A) and rotate
sensor (B) until the voltage is in the correct range.

Reel Tine Pitch
Reel tine pitch is a term used to describe the position of the reel fingers in relation to the cutterbar. The reel tine pitch can
be changed by changing the reel fore-aft position and the reel cam setting. You may wish to change the reel tine pitch to
suit different harvesting conditions.
Changing the reel position has the largest impact on the reel tine pitch. Changing the cam setting, on the other hand, has a
smaller impact on reel tine pitch. For example, with the cam position range at 33°, the corresponding finger pitch range is
only 5° at the lowest point of the reel
’
s rotation.
For the best results, use the minimum cam setting that delivers the crop past the rear edge of the cutterbar and onto the
drapers. For more information, refer to
3.7.2 Header Settings, page 66
Reel Cam Settings
Changing the cam position allows you to adjust the point at which the reel fingers release gathered crop to the drapers.
Recommendations are provided for reel cam settings in various harvesting conditions.
The setting numbers are visible above the slots on the cam disc. For instructions, refer to

delivers the most even
crop flow onto the drapers without fluffing or disturbing the
material.
•
This setting will release crop close to the cutterbar. Use this
setting when the cutterbar is on the ground while
harvesting.
•
Some crops will not be delivered past the cutterbar when
the cutterbar is raised off the ground while the reel is far
forward. Therefore, set the initial reel speed so that it close
to the ground speed.
