OPERATION
REEL POSITION
IMPORTANT:
When difficulty is encountered picking up down crop, start by adjusting header angle to a
steeper position. This tilts the entire reel/sickle/draper combination and is often all that is required. See
"Header Angle" in Combine Adapter Operator's Manual for adjustment details. Adjust reel position only if
header angle adjustments are not satisfactory.
Reel fore-aft position can be adjusted mechanically
(973) or hydraulically (974) to suit various crop
conditions. A gauge decal is provided on the left reel
support arm for identifying a preferred position. The
back edge of the reel end shield is the gauge indicator
(A). For units with hydraulic header tilt as well as
hydraulic reel fore-aft, use the selector switch in the
cab to choose the desired function.
•
For straight standing crop, center the reel over the
cutterbar (4 or 5 on gauge).
•
For crops that are down, tangled, or leaning, it
may be required to move reel ahead of cutterbar
(to a higher number on the gauge).
After adjusting reel fore-aft position, check reel
clearance to cutterbar. Minimum finger to
guard/cutterbar clearance is as follows:
For 973 Headers: 5/8 inch (15 mm).
For 30’ 974 Headers: 1-3/4” (45mm) at each end and 2-1/4” (58mm) at center.
For 36’ 974 Headers: 1-3/4” (45mm) at left end, 1” (25mm) at right end and 2-3/8” (60mm) at center.
NOTE:
Reel clearance to cutterbar is factory set as above. Adjustment should not normally be required. If
required, refer to Maintenance/Service section for adjustment procedure.
To adjust reel fore-aft position (mechanical):
1. Lower reel so support arms are horizontal.
2. Remove bolt (A) at each support arm.
3. Using a 15/16” wrench on sprocket inside
reel arm, slide reel to the desired position.
If reel binds on arms from misalignment,
move in smaller increments (two holes at
a time).
4. Install and tighten bolt (A). Be sure the
same hole is used at each arm.
5. Check reel clearance to cutterbar. See
measurements above.
NOTE:
For 973 Headers, a kit is available
to provide hydraulic reel fore-aft adjustment.
See Options and Attachments section.
