Adjusting Reel Cam - MacDon D65 Operator's Manual

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 and
gives a finger tip speed approximately 35% faster than the
reel speed.
• Cutting height is set to approximately 8 in. (203 mm) to
leave a significant amount of stubble. In damp materials
such as rice, it is possible to double ground speed
because the amount of material that is being cut is less.
NOTE: High cam settings with the reel fore-aft
position at 4–5 severely decreases the
draper capacity because the reel disrupts
crop flow across the drapers. The fingers
are still engaged in the crop that is moving
on the drapers. High cam settings are
recommended only with the reel at or
close to full forward settings.
The reel to cutterbar clearance should always be checked following adjustments to reel tine pitch and
reel fore-aft position.
Refer to Section 6.8.1 Reel Clearance to Cutterbar, page
Refer to Section 4.6.1 Header Settings, page 46
crop conditions.
