Position 3
Cam Position 3, Reel Position 6 or 7
is mainly used to leave
long stubble.
•
This position allows the reel to reach forward and lift the
crop across the knife and onto the drapers.
•
This setting results in the reel fingertip speed being
approximately 30% faster than the reel speed.

Position 4
Cam Position 4, Reel Position 2 or 3
is used with the reel is fully
forward. Using this setting results in the header leaving the
maximum amount of stubble when harvesting in lodged crops.
•
This position allows the reel to reach forward and lift the
crop across the knife and onto the drapers.
•
This setting results in the reel fingertip speed being
approximately 35% faster than the reel speed.

–
Position 4
Cam Position 4, Header Angle at Maximum, and Reel Fully
Forward
provides the maximum amount of reel reach below the
cutterbar to pick up lodged crops.
•
This position leaves a significant amount of stubble when
the cutting height is set to approximately 203 mm (8 in.). In
damp materials such as rice, it is possible to double the
combine
’
s ground speed because of the reduction of cut
material.
•
This setting results in a the reel fingertip speed being
approximately 35% faster than the reel speed.
NOTE:
Using higher cam settings when the reel
’
s fore-aft position is set between 4 and 5 results in drastically decreased draper
capacity. This happens because the reel fingers continually engage with crop that is already moving on the drapers,
resulting in disrupted flow into the combine feeder house. Higher cam settings are recommended only when the reel is at
or close to the fully forward setting.
