INSTALL FEED DRAPER ON COMBINE ADAPTER
1. Loosen nut (G), both sides, and pull up on idler
roller to rotate to position (A). Nut (G) must be
loose enough that idler arm easily passes by
adjusting rod (J).
NOTE: Rod (J) may come out of position when
lifting idler roller. It will return to proper position
when roller is moved to working position (B).
Try moving idler roller from position (A) back to
working position (B). If roller does not pivot
over, loosen bolt (G) further. When nut (G) is
properly loosened, pull roller up to position (A)
for installation of draper.
2. Install feed draper on adapter rollers, ensuring
belt on underside seats properly on left side of
both rollers.
3. Pre-install screws (F) in connector slat. Screws
fit tightly into slat holes. To install, support slat
on both sides of hole and hammer screw into
hole. Position connector slats (D) as shown
with heads leading in direction of travel.
4. Apply draper tension as follows:
a. With nut (G) loosened per step 1, swing roller
from position (A) to working position (B),
standing on ends of roller if necessary. Take
care not to damage roller or draper seal.
b. Back off nut (H) and adjust position of nut (C)
to align bracket with welded channel as shown.
This position provides proper spring tension.
Tighten nut (H) against nut (C) to secure the
position. Repeat at other side.
c. Tighten nut (G), both sides, ensuring that
formed end of adjusting rod seats properly in
pocket formed into idler arm and that rod is
positioned at bottom of cut-out in side of pan.

cutterbar as described on page 9.
NOTE: Plates are different depending on header
model (962 or 972).
