Reel Clearance From Cutterbar
The bat reel should be adjusted to provide 2 inches (50
mm) clearance above cutterbar and/or drapers with
reel fully lowered. For pick-up reel clearances, see
Reel Operator's Manual.
Check reel clearance whenever the reel fore-aft
position is changed.
To increase reel clearance from cutterbar:
1. Lower header and reel fully.
2. At both ends of header: loosen nut (A) and turn
adjuster nut (C) clockwise to achieve proper and
consistent clearance across cutterbar. Tighten nut
(A) against nut (C) to secure the position.
NOTE: For 36' header, in addition to adjusting at
each end: At center reel arm, loosen nut (B) and
turn nut (D) clockwise. Tighten nut (B) to secure the
position.
To decrease reel clearance, loosen nuts (A) and turn
nuts (C) counter-clockwise and at 36' center arm,
loosen nut (D) and turn nut (B) clockwise.
Centering the Reel
Center the reel between the header end sheets by
adjusting the reel support arm brace (A).
To adjust:
1. Remove nut and offset washer at (E), rear of brace.
2. Position brace (A) as required to center reel.
3. Replace offset washer and nut at (E). Tighten nut to
160 ft.lbs. (215 N ⋅ m).
