PREPARING THE ADAPTER

1. Level Land Prior to 50 series Feeder House:

Install pump torque arm support (A) to bolt
welded to R/H frame member of adapter using
3/4” locknut at (K). Orient support as shown.

Contour Master and 50 series Level Land
Feeder House: Install pump torque arm
support (B) to bolt welded to R/H frame
member of adapter using 3/4” locknut at (L).
Orient support as shown.
NOTE: For 9650 Combine, bolt torque arm (C)
(with two bends) to existing torque arm using
three M12 x 30 bolts.

2. Attach locking channels (H) to adapter frame,

using locking bar (J) between channel and lock
nuts. Install channels with single-hole leg
outboard and narrower clearance to bottom on
two-hole leg as shown.
NOTE: Lock pins at bottom of combine feeder
house engage these channels. Adjust position
of channels (H) by loosening hardware and
sliding channels up and down for proper
alignment.

3. Level Land Prior to 50 series Feeder House:

Attach shield (D) to left side of adapter frame
with 5/16 x 3/4” flange bolt and nut.

NOTE: Install nut “upside down”, that is, with
serrated flange down, so flats of hex engage in
slot in adapter frame.
NOTE: For 9600 and 8820 combines, shield
(G) is not required. Remove prior to installation
of shield (D). Swing shield (D) forward for end
transport situations.

Level Land Prior to 50 series Feeder House:

Place feed auger in position (F), the most
forward of two positions.

50 series Level Land Feeder House: Place

feed auger in position (M), the middle of three
positions. Combine dust shields must be
removed. See “Preparing the Combine”, next
page.

Contour Master Feeder House: Place feed

auger in position (L), the most forward of three
positions.

To adjust:

a. Loosen bolts at (E) and (K).
b. Remove bolts at (F) (L) or (M) and swing auger

to desired position.
