understood by all who operate it.
Never allow children or young teen-
agers to operate the tractor and snow
blower.
Be sure you know how to stop the trac-
tor and auger at a moment's notice.
Instruct children to keep away from the
area of operation at all times.
Check the tractor and blower to make
certain both are in good operating con-
dition"

OPERATING TIPS
A
5.
1. Whenever possible, discharge snow down
wind.
Do not attempt to remove ice or hard
packed frozen snow.
Always overlap each pass slightly to as-
sure complete snow removal.
Use extreme care when freeing a frozen
or stuck auger or chute. Always turn
off the tractor first.
If tractor is equipped with Hydraulls T,iff,
operate with the lift lever in the "float"
(full forward) position. Never apply down
pressure to the snow blower. With the
hydraulic lift lever in the ?'floatrr posi-
tion, the skid shoes will remain on the
surface even though operating on uneven
terrain.

METHODS OF SNOW REMOVAL
Fisure 2
A definite pattern of operation is required
to thoroughly clean the snow area. This
pattern wiII avoid a second removal of snow
and avoid blowing snow in unwanted places.
Where it is possible to blow snow to right
and left, as on a long driveway, it is ad-
vantageous to start in the middle. See
Figure 2. Work from one end to the oppo-
site end blowing snow to both sides without
NO SNOW PILED ON IEFT SIDE
Figure 3
changing direction of discharge chute. If
snow can only be blown to one side of the
driveway, start on the opposite side. See
Figure 3. At the end of each pass, rotate
chute to opposite side for the return pass.
At the end of each succeeding pass, rotate
chute to opposite side to maintain direction
of throw into the same area.
TIRE CHAINS AND WHEEL WEIGHTS
The use of tire chains anC r,vheel weights,
Figure 4, is recommended for snow re-
moval operation. The extra traction re-
sulting gives the tractor operator maneu-
verability in handling heavy snow removal
jobs. These accessories are sold by your
dealer and are not included with the snow
blower.
The same wheel weights can also be attached
to the front of thetractorwhengardenplowing
or tilling by adding the Model H18 Front
Weight Bracket Kit.

PREPARING FOR SNOW REMOVAL
Disengage the attachment drive
clutch when starting engine and
when transporting the snow
blower. Before the first snow-
fall, the area in which snow re-
moval is to take place should
be cleared of all stones, sticks,
etc., which might be picked up
by the snowblower. OBSTACLES
SUCH AS DRTVEWAY MARKERS,
WATER OR GAS SHUT OFFS,
ETC" SHOULD BE MARKED SO THEIR LO-
CATIONS UNDER THE SNOW ARE VERY
OBVIOUS.
To become familiar with the controls, op-
erate the tractor and snow blower in a clear
area before removing snow. The more
familiar you become with the snow blower,
the better results you wiil have in its use.
SNOW CONDITIONS
Snow removal conditions vary so greatly
from the first light fiuffy snowfall to wet
or heavy snow that operating instructions
must be flexible. The operator must op-
erate according to depth of snow, wind di-
rection, temperature, and surface conditions.
The auger speed and blowing distance are
directly related to the engine speed. For
maximum removal volume and distance,
maintain high engine RPM (three -quarters
to fuII governed throttte). Operatingatlower
throttle settings will reduce the blowing dis-
tance and increase fuel economy. Always
operate the tractor in low range for safe and
efficient snow removal. The speed control
lever should be operated to provide a ground
speed most compatible with the snow re-
moval conditions.
In extremely deep snow, raise snow blower
into transport and remove top layer first.
Lower the snow blower to the ground and
repeat process to remove the balance of
snow. Working with repeated passes into
and out of drifts will eventually move even
the deepest of snow piles.
A light coat of wax applied to the inside
surfaces of the discharge chute anddeflector
wiII help to prevent snow and slush from
sticking. The inside of chute and deflector
should be waxed several times during the
snow removal season. Use any good com-
mercial grade of paste wax or spray sili-
cone which is available from your dealer
or from your local hardware store.
Allow ample engine warm up time before
starting snow removal.
Best results are obtained when snow is re-
moved as soon as possible aJter it falls.
Check each item covered in the "ADJUST-
MENTS" and "MAINTENANCE" sections of
this manual before operating the snow blower.

By angling the deflector upwardr the snow
will be cast higher and further from the
tractor. When angled downward, the de-
flector wili direct the snow closer to the
ground and it will be cast a shorter dis-
tance. Tighten the locking levers when
the deflector is adjusted to the desired
angle"

3. Skid Shoes - See Figure 6. Slotted
mounting holes are provided to obtain
the oesired clearance between the base
of the auger housing and the surface of
the area to be cleared. When operating
on a smooth surface such as cement or
asphalt, the skid shoes can be set at
the lower end of the slots. ff operating
on a rough surface such as gravel or
earth, the skid shoes should be set at
the upper end of the slots to prevent
foreign material from entering and
possibly damaging the snow blower.
4" Auger Drive Chain - The chain slack at
the lower section should be held to be-
tween 3/8" and 1/2" under normal finger
pressure midway between the drive
sprockets. Adjust the idler block bolt
on the upper chain section, up or down,
as necessary to maintain proper slack.
Should the available adjustment for the
idler block be used up, the overall chain
Iength can be decreased by removing one
Iink and adding the offset link furnished
with snow blower. The idler block can
also be rotated or turned around if the
chain wears in excessively.
MAINTENANCE
Never attempt to service or make
adjustments while the snow
blower or tractor is running.
Grease the discharge chute control crank,
chute guides and the chute base ring. Figure
1, daily to keep the crank turning freely.
Once a month during season or every 25
operating hours, lubricate the auger drive
chain with Case Heavy Duty Chain and Cable
Lubricant available through your Case Com-
oact Tractor Dealer.

In order to reduce thesizeof theshipping
carton and hold transportation costs to a
minimum the Mounting Bracket is de-
tached from the Auger Assembly.
Position the Mounting Bracket between
the Auger Adapter P1ates as shown in
Figure 10. hsert a spacer in eachof the
Adapter Plates. Bolt the Mounting
Bracket to the Adapter Plates with the
plain washers to the outside and lock
nuts at the inside.
Three round head bolts are furnished to
attach the chute guides to the discharge
spout instead of two as shown in Figure
14. InstaII the bolts at the two side
guides with the round heads to the in-
side. For ease of assembly, install the
front guide boit with the nut and lock-
washer to the inside.
The heavy duty skid shoes can be rotated
from one side of the blower to the other
for increased life when the leading edges
wear down.
The shoes can be installed with the skids
facing either inward or outward. If the
skids are installed inward they wiII pro-
tect the cutting edge by keeping it 3/16"
higher than the skids when they are ad-
justed to the "minimum" clearance po-
sition" If the skids are installed inward
the nuts and lockwashers must be to the
inside to provide a "smooth" outside
suriace.
If the shoes are installed with the skids
to the outside they can be adjusted fur-
ther upward if desired to place the cut-
ting e$ge in direct contact with a hard
level surface such as a concrete or as-
phalt driveway. If installed in this man-
ner the nuts andlockwashers canbetothe
outside. This installation is not recom-
mended when operating on dirtrgravelor
uneven surfaces.
The replaceable cutting edge can also be
reversed for increased life when the
leading side_ wears down.
Auger Drive Chain Adjustment -- The
idler block described on page 6, para-
graph 4, has been eliminated. The two
auger mounting hubs have four holes in an
eccentric circle around the auger mount-
ing shaft. The hubs also have an ori-
entation hole near the shaft. Chainslack
at the lower section should be heldtobe-
tween 3/8" and lf 2" under normalfinger
pressure midway between the drive
sprockets.
When adjustment is necessary, remove
the two bolts from the right hand mount-
ing hub and rotate the hub in either di-
rection until correct chain tension is
obtained and reinstall the two bolts. lm-
portant - To keep the ehain in line with
the auger sprocket, rotate the left hand
mounting hub to locate the orientation
hole in the same position as the right
hand hub.
Turn the auger to make certain there is
no interference with the housing. If
interference is encountered, remove the
two bolts from the right hand mounting
hub and rotate the hub in the opposite
direction until correct tension is obtain-
ed. Reset the left hand hub to place
the orientation hole in the same location
as the right hand hub.
Should the available adjustment on
the auger mounting hubs be used
up, the overall chain length can be
decreased by removing the offset
(half) lirk from the chain.
