NOTE: TIRE CHAINS CANNOT BE USED WiTH THE
MOWER HOUSING ATTACHED.
BEFORE OPERATING YOUR MOWER.
REFER TO PAGE 2.
a. Use the runner on the R.H. side as a guide; the blade
cuts approximately an inch outside the runner (Fig.
t8).
b. Drive so that clippings are discharged onto the area
that has been cut. Have the cut area to the right of
the machine. This wit/ result in a more even distri-
bution of clippings and more uniform cutting.

\OPERA TtON
c . When mowing large areas (Fig. 79), start by turning
to the right so that the chppings w/// discharge away
from shrubs, fences driveways, etc. After one or
two rounds, mow in the opposite direction making
!eft hand turns until finished.
d. If grass is extremely taft, it should be mowed twice.
The first time cut relatively high; the second time
to the desired height.
e. The left hand side of mower should be used for
trimming.
r, Do not mow tall, dry grass over 6 inches tall. It is a fire
hazard

With Every Mowing
1. Make sure a// nuts on bolts are tight and cotter
pins and retainer springs are secure.
2. Observe a// safety precautions.
3. Keep tractor we//lubricated (refer to page 20).
First 2 Hours (Two Mowings)
!. Change Engine Oil
Changing off after the first two hours (or two mow-
ings) will help eliminate break-in residue which might
be damaging to your engine.
NOTE: BE CAREFUL NOT TO ALLOW DIRT TO ENTER
THE ENGINE WHEN CHANGING OIL.
a. Drain oil with engine warm,
b Loosen oil drain wing nut (Fig, 20) and remove
dipstick.
c Catch oil ma suitable container.
d Tighten off drain wing nut.
e Refill engine oil (See below). Refill capacity is
1-1/2 quarts. NOTE: DO NOT OVERFILL.
f Replace dipstick.

7. Brake Adjustment
This tractor is equipped with an adjustable brake
system mounted on the right side of the transaxle
(Fig. 22),
IF TRACTOR REQUIRES MORE THAN
SiX FEET STOPPING DISTANCE IN
HIGHEST GEAR, THEN BRAKE MUST
BE ADJUSTED,
tNTENANCE
2,
a. Depress clutch/brake pedal and engage parking
brake,
b. Measure distance between brake operating arm
and nut "'A" on brake rod.
c . If distance is other than 1- !/2", loosen jam nut
(Fig. 22) and turn nut "A'" until distance becomes
1-1/2". Retighten jam nut against Nut "A",
Road test tractor for proper stopping distance as
stated above. Readjust if necessary,
Tire Care
Maintain tire pressure in front at I4 PSI and rear tires
at 12 PS!.
Blade Sharpening
For best results mower blades must be kept sharp. The
blades can be sharpened with a few strokes of a file or
on a grinding wheel. We suggest they be sharpened
after every 25 hours of mowing. Do not attempt to
sharpen while on mower. If you mow in sandy soil
check the blades after each two mowings. The sand
wears the blades away rapidly,

When grinding, care should be taken to maintain
blade balance and the blade should be checked
for proper balance before remstaflation on mower.
Unbalanced or bent blade will cause excessive
vibration when running, and eventual damage to
mower or engine. Replace bent or damaged
blades.
To check blade balance, drive a nail into a beam
or watt. Leave about one inch of the straight nail
exposed. Place center hole of clean blade over the
head of the nail (Fig. 23). NOTE: CENTER HOLE
OF BLADE ON NAIL. IF BLADE iS PROPERLY
BALANCED, BLADE SHOULD REMAIN IN POSI-
TION SHOWN IN FIG. 23. IF EITHER END OF THE
BLADE MOVES DOWNWARD, BLADE tS NOT
BALANCED. SHARPEN THE HEAVY END UNTIL
BLADE tS BALANCED.

NOTE: DO NOT OVERFILL,
b. Keep battery and terminals clean.
c. Keep battery bolts tight.

3. Change Engine Oil
The best time to change engine oil is at ":he end of
aday's operation when all dirt and foreign materials
are suspended in the hot oil. See chart, page !6,
(OPERATING IN DUSTY CONDITIONS MAY REQUIRE
MORE FREQUENT SERVICING)

5. Lubricato Steering And Front Wheels
There is a grease fitting on each front wheel Use
a grease gun to give each grease fitting two shots
of extreme press ure lubricating grease Amdex No. 1
or equivalent [available through your Sears Service
Center). Use 30 weight oil to lubricate front spind-
les (Fig. 26).
6. Oil Pivot Points
Place several drops of SAE 30 oil at points where
parts move against each o ther, especially:
a. Front wheel spindles.
b. Hood hinges.
c. Foot peda/ shaft (both ends).
d. Lift shaft (both ends).
SEE L UBRtCA T/ON CHART, PAGE 20.
