7.9.8 Reel Height
Depending on crop height, adjust reel height to
carry material through the sickle onto the
drapers. Operate combine hydraulics as
required. Refer also to Section 7.9.9 Reel
Fore-Aft Position.

(Also Increase Reel Speed
and/or Cam Setting)
Bushy or Heavy Standing Up
Indications that reel may be too low are:
 crop loss over the header back tube,
 disturbance of crop on the drapers by
the reel fingers, or
 crop being pushed down by the tine
tubes.
IMPORTANT
Maintain adequate clearance to
prevent fingers contacting the knife
or the ground. Refer to Section
8.12.1 Reel Clearance to Cutterbar.
Refer to Section 7.8.1 Header Settings for
recommended reel height in specific crops and
crop conditions.
7.9.9 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 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.
Refer to Section 7.8.1 Header Settings for
recommended reel positions in specific crops
and crop conditions.
7.9.9.1 Hydraulic Adjustment: Fore-Aft
h. Select the fore-aft adjust mode on the selector
switch in the cab.
i. Operate the hydraulics to move the reel to the
desired position, again using the gauge as a
reference.
j. Check reel clearance to cutterbar after making
changes to cam setting. Refer to Section
8.12.1 Reel Clearance to Cutterbar for
measurements and adjustment procedures.
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.
