Adapter Mounting Instructions
for John Deere Combines
PREPARING THE COMBINE
1. For 7720, 9500 and CTS combines, check with
Combine dealer to ensure combine is equipped
with tire size, rear ballast etc. to carry larger
headers.
2. IMPORTANT: To prevent damage to feeder
house and/or adapter feed auger, remove
feeder house dust shields (A).
NOTE: Contour master shields are not
removable. The adapter feed auger has been
moved forward to compensate for this.
3. Lock pin (B) both sides must be in retracted
position before attaching adapter.
4. If combine is equipped with variable speed
header drive, set header drive speed to 520
RPM.
5. Set feeder chain to high speed. Additional
chain links will be required. Refer to Combine
Operator’s Manual.
6. Move front drum back to the mid-position or
further to loosen feeder chain. After adapter is
attached to combine, tighten feeder chain. If
there is interference with the feed auger,
remove a link from the feeder chain. Recheck
clearance when the front drum of the feeder
house is floated fully up.

Attach spline shaft provided with adapter to
feeder house L/H output drive as follows:
7720, 9500, 9510 & CTS
a. Remove existing sprocket coupler.

just tight enough to eliminate gaps between

shaft and tighten the two 4-½ inch long bolts
(D) evenly to 80 ft.lbs. (110 N·m).
