MacDon 974 FlexDraper - Manual (Page 33)

Form # 147083 Issue 01/07 31
OPERATION
REEL POSITION (continued)
To adjust pick-up reel finger pitch:
If adjusting the reel fore-aft position does not provide proper feeding, the finger pitch can be adjusted by
repositioning bolt (B).
Slot 1: least aggressive (standing crop)
Slot 5: recommended starting position
Slot 9: most aggressive (down, tangled crop)
TIP: In bushy crop that sits high on drapers, try a
more aggressive finger pitch to reduce carryover.
The Trouble Shooting section includes other tips to
improve performance.
1. Loosen bolt (B) and disengage from current
position.
2. Install and tighten bolt (B) in desired position
in arm.
3. For split reels, repeat adjustment at R/H arm
by loosening bolts (C) and (D), moving bolt (C)
to same position as center arm and tightening
(C) and (D).
4. Check clearance to cutterbar:
When operating reel with an aggressive finger
pitch, be sure that fingers will not contact
sickle when flexed back by crop, as at (R).
Check all possible points of contact between
points (X). Depending on reel fore-aft position,
minimum clearance can occur at guard tine,
hold-down or 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.
