9.11.10 Reel Fore-Aft Position
Reel position has been found to be a critical
factor in achieving good results in adverse
conditions.
The reel position is factory-set for average
straight standing crop, and can be adjusted
forward and backward for different crop
conditions.
A gauge decal is provided on the reel right
support arm for identifying a preferred position.
The back edge of the reel cam disc is the gauge
indicator.
 For straight standing crop, center the reel
over the cutterbar (4 - 5 on gauge).
 For crops that are down, tangled, or leaning,
it may be required to move reel ahead of
cutterbar (to a lower number on the gauge).
IMPORTANT
When difficulty is encountered picking
up flattened crop, adjust header angle
to a steeper position. This tilts the entire
reel/sickle/draper combination and is
often all that is required.
Refer to “Header Angle” section in
Combine Operator’s Manual for
adjustment details.
Adjust reel position only if header angle
adjustments are not satisfactory.
NOTE
In difficult to pick up crops such as rice
or severely lodged crops that require
full forward positioning of the reel, the
reel tine pitch can be set to provide
proper placement of the crop onto the
drapers.
Refer to Section 9.11.11 Reel Tine
Pitch for adjustment details.
IMPORTANT
Operating with the reel too far forward
can cause the fingers to contact the
ground before the Cutterbar.
Lower the skid shoes or adjust header
tilt as required when operating with the
reel in this position, otherwise, damage
to the fingers will occur.
9.11.10.1 Mechanical Adjustment: Fore-Aft
WARNING
Stop combine engine, and remove key before
making adjustments to machine. A child or
even a pet could engage the drive.
a. Lower or raise reel so support arms are
horizontal.
b. Remove pin (A) at each support arm.
c. Using a 15/16 in. wrench on bolt (B) turn sprocket
inside reel arm to slide reel to the desired
position. If reel binds on arms from misalignment,
move in smaller increments (two holes at a time).
d. Re-install pin (A). Be sure the same hole is used
at each arm.
e. Check that the reel is evenly adjusted.
f. Check reel clearance to cutterbar after making
changes to cam setting. Refer to Section 10.14.1
(D50, D60) or 10.14.2 (FD70) Reel Clearance to
Cutterbar for measurements and adjustment
procedures.
