PRINCIPAL COMPONENTS
The snow blower has three main operating compo-
nents. An auger dislodges the snow and carries it to a
central fan. The snow is then discharged by the fan and
directed away from the blower through a controllable
chute.
The snow blower is mounted on a tractor 3-point hitch
and driven by the tractor PTO. A centrally located gear-
box directs power to the fan and auger.
TRACTOR REQUIREMENTS
3-Point Hitch
The SB54.30 and SB64.30 snow blowers require the
tractor to be equipped with a Category 1 three-point
hitch. The SB74.30 and SB84.30 snow blowers re-
quire the tractor to be equipped with a Category 1 or
Category 2 three-point hitch.
Hydraulic Circuit
Either closed-center or open-center systems can be
used for the optional hydraulic spout control.
Tire Configuration
For best results, the tractor wheels should be set nar-
rower than the cutting width of the snow blower. Wider
wheel settings will cause snow to be pulled under the
tractor and may require additional passes.
PTO Shaft
The tractor must be configured to accept a 1-3/8" 6-
spline 540 RPM system and must meet horsepower
specifications. See specifications, page 4.
Tractor Stability
■ A minimum 20% of tractor and equipment weight
must be on the tractor front wheels when attach-
ments are in transport position. Without this
weight, front tractor wheels could raise up re-
sulting in loss of steering. The weight may be
attained with front wheel weights, ballast in
tires, front tractor weights or front loader. Weigh
the tractor and equipment. Do not estimate.

ATTACHING SNOW BLOWER TO
TRACTOR WITH A 3-POINT HITCH
Figure 2
1. Make sure the parking stand is lowered. To do this,
remove the round wire lock pin (item 9) from the
parking stand (item 8), lower the parking stand and
insert the round wire lock pin (item 9) under the
snow blower attachment tube.
2. Move the tractor into position in front of the snow
blower. Move back slowly and carefully, not allowing
anyone to be between the tractor and the snow blower.
3. Turn off the tractor engine.
4. Attach the tractor lower arms (item 2) with the two
pins (item 1) and secure in place with the 7/16 "ring
pins (item 3) in the upper holes (item 10) for small
tractors and in the lower or middle holes (item 4) for
larger tractors.
5. Attach the tractor center link (item 5) between the
upper attachment plates of the snow blower (item 7)
with the pin and the ring pin (item 6) provided with
the tractor.
6. Adjust the snow blower using the center link of the
tractor (item 5) so that the snow blower is perpen-
dicular to the ground.
7. Adjust the anti-sway devices of the tractor to pre-
vent lateral swinging of the snow blower. Make sure
there is no contact with the tires.
8. Raise the parking stand. To do this, remove the
round wire lock pin (item 9) from the parking stand
(item 8), raise the parking stand and insert the
round wire lock pin (item 9) over the snow blower
attachment tube.
9. Go to Driveline Attachment section for further
instructions.
■ Before connecting the snow blower driveline to
tractor drive shaft, make sure driveline is not
too long in raised, lowered and middle position.
If the driveline is too long it must be shortened,
to avoid damaged to tractor. See pages 13 to 15
for instructions.
