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 generates a fingertip speed that is
approximately 30% faster than the reel speed.
Cam Position 4, Reel Position 2 or 3 is used with the reel
fully forward to leave the maximum amount of stubble in
lodged crops.
• This position allows the reel to reach forward and lift the
crop across the knife and onto the drapers.
• This setting generates a fingertip speed that is
approximately 35% faster than the reel speed.
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.
• Leaves a significant amount of stubble when cutting
height is set to approximately 8 in. (203 mm). In damp
materials such as rice, it's possible to double the ground
speed because of the reduction of cut material.
• This setting generates a fingertip speed that is
approximately 35% faster than the reel speed.
NOTE:
Higher cam settings with the reel fore-aft position set
between 4–5 sharply decreases the draper capacity
because the reel disrupts the crop flow across the
drapers and the fingers engage the crop that is moving
on the drapers. High cam settings are recommended
only with the reel at, or close to, full forward settings.
IMPORTANT:
The reel to cutterbar clearance should always be checked following adjustments to reel tine pitch and reel fore-aft
position, refer to 5.8.1 Reel Clearance to Cutterbar, page
