SNOWBLOWERS
Before attempting to operate the Snowblower, be sure to read the
section entitled I'SAFE SNOW REMOVAL IS NO ACCIDENTT'.
A11 major bearings of the MA 210, MA 211, and MA 212 Snowblower
tlat require lubricant are permanently lubricated, or are lubricated
from the tractor transmission. Holever, the operator should check the
oil level in- the gear box by removing the upper pipe p1ug. Oil should
come up to the bottom of this ho1e. If the oil level should ever be low,
add worm type gear lubrieant as recommended for truck worm-gear
axles in your atea.
The Snowblower Drive housing mounts to the front of the tractor with
four bolts, the same as other Gravely power Attachments. When attach-
ing to the Model rl,r Tractor, tJre chute control crank should be attached
to the top sprocket housing shaft of the Snowblower with the rubber con-
nector and two (2) clamps which are provided. See Figure 1.
The crank
with the crank

should then be mounted to
support and crank support the tractor left-driving handle clamp as shown in Figure 2.

ADJUSTMENTS:

Figure 2
When attaching the 34!t Snowblower to the Westchester Tractor, con-
nect the control rod to the top sprocket-housing shaft with one of the two
rubber connectors provided, and use two of the four elamps provided.
Mount the control crank support bracket to the Westchester left side body
hinge pivot point by removing the body hinge pivot bolt and installing the
special locking bolt included with the Snowblower. Include the spacer be-
hveen the crank support bracket and the Westchester body. Pass the crank
through the crank support bracket and mount the crank to the control rod
with the second rubber connector and the remaining two clamps.
NOTE: If the Snowblower is uneven with the ground after mounting on
traetar, check the air pressure in the ttactor tires.
Discharge Chute
To position the Discharge Chute, turn the control crank. The Dis-
charge Chute will rotate approximately 165 degrees from extreme left,
through the vertical position, to the extreme right. As the crank is turned,
the deflector opening is also rotated from the extreme }eft position through
a forward position approximately 180 degrees to the extreme right position.
Deflector
To provide accwate placement of the blown snow near the blower on

-3-
either side or forward throw, loosen the large wing nut on the deflector
and adjust the deflector position.
Skids
To raise or lower the Snowblower cutting edge, first disengage the
power take-off and stop the tractor engine. Then loosen the skid mount-
ing bolts and slide the skids up or down as desired, and tighten the skid
mounting bolts securely. This adjustment can be made more accurately
if the cutting edge is placed on blocks while the adjustment is made.
ReeI Clutch
The ReeI Clutch is properly adjusted at the factory. If it should be-
come necessary to tighten the protective friction clutch in the reels, turn
off the traetor engine, disengage the power take-off, and block the rota-
tion of the fan. Now tighten the large nut on the left end of the reel shaft
(as viewed from the rear of the Snowblower).
The nut shor.rld be tightened to 85 to 95 Ib. feet of torque. This would

ACCESSORIES:
-A-

Control Shaft C1utch
The fan housing is prevented from rotating by a small friction clutch
on the top sprocket housing shaft, except when the control crank is turned
by the operator. The resistance of the clutch may be varied by adjusting
the nut on the top sprocket housing shaft. Adjust the nut so that it is just
tight enough to prevent the fan housing from rotating during operation of
the Snowblower except when the fan housing is rotated by the control erank.
A special Accessory Kit is available which includes:
Drift Cutters
Figure 4
Two Drift Cutters are provided. These mount inside the reel housing
ends and extend upward to slice through snow up to B0r? deep. The Drift
cutters are flared to assist in turning in deep snows. No adjustment is
necessary.
Casters
Two caster weldments and mounting brackets are included. These
bolt to the inner sides of the frame and may be used in place of the skids.

OPERATTNG HINTS:

Figure 5
The caster bracket holes are slotted, and three (3) pairs of holes are pro-
vided in the frame for height adjustment.
Model No. Decal
This decal is shipped with the accessory kit, and is to be installed
in a proteeted location on the easter mounting bracket or drift cutters.
Keep the engine under full load when using the Snowblower. With the
Swiftamatic Transmission, use low axle range which slows ground speed
to a virtual crawl, but permits the Snowblower to run fast in direct rela-
tion to the engine revolutions per minute.
If you have standard transmission, you will have to shift between high
and low in keeping with snow depth and density. For extended operation in
heavy slrows, we recommend use of the Gravely gear-reduction wheels.
If the tractor stops suddenly while operating the Snowblower, check
the vent in the fuel tank cap. Sometimes snow will clog this small open-
ing, especially on older tractors with hoods that do not cover the fuel tanL.
We recommend use of anti-ice fuel additives, dnd keeping the fuel tank as
full as possible at aLL times to minimize condensation, and subsequent fuel
line or carburetor freezing.

CAUTION:
*6-
When blowing sno\M into the wind, the diseharge chute shouLd be ad-
justed to blow the snow }ow, and just over the top of unmoved snow.
There are several silicon-base products avaiSahle thrat you can use to
coat the working surfaces of the Snowblower, making it more difficuLt for
snow and ice to adhere to these parts. Regular floor or ski wax is also
effective.
When blowing Snow from gravel or other non-paved surfaces, the
Snowblower should be raised by adjusting the skids or casters. This will
minimize chances of rocks and other objects being picked up and thrown
by the blower.
With the Deluxe Snowfulower, only one adiustment can be made safely
with the attachment running. The discharge spout can be adiusted hori-
zontally by turning the control crank rod at the rear of the tractor.
To adjust the discharge spout vertically (on both the Deluxe and earlier
models), disengage the attachment, and wait until the fan and reel both are
fully stopped.
For any other adjustment or repair, disengage the Snowblower and
stop the txactar engine. Be sure the Snowblower has stopped completely.
Use extreme caution when operating on gravel and other non-paved
surfaces. The Snowblower can pick up and expel heavy objects with suf-
ficient velocity to injure pelsons or damage property. Skids should
always be used for work on non-paved surfaces, and care should be used
in selecting the direction of the discharge spout.

Safe Snow Removal
Is No Accident
Improper use of snow removal equipment on the part of the operator can re-
sult in injury. To reduce this possibility, give complete and undivided attention to the
job at hand.
Protect yourself and others by following these safety tips:
1. Stop motor before cleaning discharge, removing obstacles, making
adjustments (except with the control crank or when adjusting the
deflector), or when leaving the operating position.
2. Disengage the power take-off and wait till the fan stops before ad-
justing the deflector. Never direct discharge at bystanders, or
allow anyone in front of machine -- debris may be hidden in the
snow.
3. Keep children and pets a safe distance away.
4. Do not allow children to operate machine, nor allow adults to
operate it without proper instruction.
5. Adjust height to clear gravel or crushed rock surface.
6. Exercise caution to avoid slipping or falling, expecially when
operating in reverse.
7. Know the controls and how to stop quickly -- read the Ownerrs
Manual.
8. Hand1e gasoline with care. It is highly flammable.
A. Use approved gasoline container.
B. Never add gasoline to a running engine. FilI the
tank outdoors, and wipe r:p spilled gasoline.
C. Replace gasoline cap securely.
D. Open doors if engine is rtm in garage. Exhaust
fumes are dangerous.
9. Disengage all elutches and power take-off before starting motor. Keep
hands, feet, and clothing away from power driven parts.
10. Keep machine in good operating condition, and keep safety devices in
p1ace.
