7.1.4 CR

Feeder

Deflectors

For New Holland CR 960, 9070, and 9080
combines, feeder kits have been installed on the
adapter at the factory to improve feeding into the
feeder house.

They may also have been installed as an option
on older machines. If necessary, they can be
removed.

CA20 adapters for the CR Models listed have
short feeder kits installed at the factory. Long
feeder kits are provided for narrow feeder house
combines, and are dealer-installed to replace the
short feeder kits.

If required, replace the feeder deflectors as
follows:

a. Determine position of existing deflector (A) by

measuring gap “X” between deflector forward
edge and pan.

b. Remove two bolts (B), and nuts securing

deflector (A) to adapter frame and remove
deflector.

c. Position replacement deflector, and secure with

bolts (B) and nuts. Maintain dimension “X” from
existing deflector for replacement deflector.

d. Repeat for opposite deflector.

e. After attaching header to combine, extend

center-link fully, and check gap “X” between
deflector and pan.

Maintain 7/8 in. (22 mm) +/- 1/8 in. (3 mm).

7.1.5 Auger

Drive

The adapter auger is chain driven from a sprocket
that is mounted on the input shaft from the
combine, and which is enclosed in the drive
gearbox.

The speed is determined by the combine input
shaft, and is matched to each particular combine,
so no adjustment is necessary.

However, optional drive sprockets are available to
change the auger speed to optimize auger
performance. See your MacDon Dealer.

NOTE

For special conditions, 20T, 22T, and
26T sprockets are available to change
adapter feed auger speed. Consult with
your MacDon Dealer.
