Adapter Mounting Instructions
for John Deere Combines
PREPARING THE COMBINE
1. 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 drum, remove all feeder house
dust shields (A), closure panels etc. that are
removable.
NOTE: Contour master dust shield is not
removable. The adapter feed drum must be moved
forward to compensate for this. See page 34.
Contour master filler plates (G) should be removed.
3. Lock pin (B) both sides must be in retracted position
before attaching adapter.
4. For models with variable speed feeder house drive,
set header output shaft speed to 520 rpm.
5. Set feeder chain to high speed. For older combines,
additional chain links will be required to move chain
to larger sprocket at (E). On newer combines the
adjustment range allows for this repositioning. Refer
to Combine Operator’s Manual.
6. Contour Master: To improve performance, move
feeder chain as far forward as possible by adding
links.
7. Adjust combine feed drum height to GRAIN position.
Refer to Combine Operator’s Manual.

spline shaft provided with adapter to feeder house
L/H output drive as follows:
7720, 9500, 9510 & CTS
a. Remove existing sprocket coupler.
b. Ensure that the three 3 inch long bolts (C) are just
tight enough to eliminate gaps between parts, but
no tighter.

and tighten the two 4-½ inch long bolts (D) evenly to
80 ft.lbs. (110 N·m).
d. Tighten the three 3 inch long bolts (C) to 80 ft.lbs.
(110 N·m).
