SAFE OPERATION PRACTICES FOR RIDING VEHICLES
1. Know the controls and how to stop quickly—
READ THE OWNER’S MANUAL.
2. Do not allow children to operate vehicle. Do
not allow adults to operate it without proper

allowed to use your mower.
3. Do not carry passengers.
4. Keep the area of operation clear of all
persons, particularly small children and pets.
Stop engine when they are in the vicinity of
your mower. Although the area of operation
should be completely cleared of foreign
objects, a small object may have been over
looked and could be accidently thrown by the
mower in any direction.
5. Clear work area of objects which might be
picked up and thrown by the mower in any
direction.
6. Disengage all attachment clutches and shift
into neutral before attempting to start engine.
7. Disengage power to attachment(s) and stop
engine before leaving operator position.
8. Disengage power to attachment(s) and stop
engine before making any repairs or adjust
ments. Disconnect the spark plug wire and
keep the wire away from the plug to prevent
accidental starting.
9. Before attempting to unclog the mower or
discharge chute, stop the engine and be sure
the blade(s) have stopped completely. Dis
connect the spark plug wire and keep the wire
away from the plug to prevent accidental
starting.
10. Disengage power to attachment(s) when
transporting or not in use.
11. Take all possible precautions when leaving
vehicle unattended such as disengaging
power-take-off, lowering attachments, shift
ing into neutral, setting parking brake,
stopping engine and removing key.
12. Do not stop or start suddenly when going
uphill or downhill. Mow up and down face of
steep slopes; never across the face.
13. Reduce speed on slopes and in sharp turns to
prevent tipping or loss of control. Exercise
extreme caution when changing direction on
slopes.
14. Stay alert for holes in terrain and other hidden
hazards.
15. Use care when pulling loads or using heavy
equipment.
A. Use only approved drawbar hitch points.
B. Limit loads to those you can safely
control.
C. Do not turn sharply. Use care when
backing.
D. Use counterweight(s) or wheel weights
when suggested in owner’s manual.
16. Watch out for traffic when crossing or near

17. When using any attachments never direct dis
charge of material toward bystanders nor
allow anyone near vehicle while in operation.
18. Handle gasoline with care—it is highly
flammable.
A. Use approved gasoline container.
B. Never remove cap or add gasoline to a
running or hot engine or fill fuel tank
indoors. Wipe up spilled gasoline.
C. Open doors if engine is run in garage-
exhaust fumes are dangerous. Do not run
engine indoors.
19. Keep the vehicle and attachments in good
operating condition, and keep safety devices
in place. Use guards as instructed in owner’s

20. Keep all nuts, bolts, and screws tight to be
sure the equipment is in safe working condi
tion.
21. Never store the equipment with gasoline in
the tank inside a building where fumes may
reach an open flame or spark. Allow engine to
cool before storing in any enclosure.
22. To reduce fire hazard keep engine free of
grass, leaves or excessive grease.
23. The vehicle and attachments should be
stopped and inspected for damage after
striking a foreign object, and the damage
should be repaired before restarting and
operating the equipment.
24. Do not change the engine governor settings or
overspeed the engine.
25. When using the vehicle with mower, proceed
as follows:
(1) Mow only in daylight or in good artificial
light.
(2) Never make a cutting height adjustment
while engine is running if operator must
dismount to do so.
(3) Shut the engine off and wait until the
blade comes to a complete stop before
removing the grass catcher.
(4) Check blade mounting bolts for proper
tightness at frequent intervals.
26. Check grass catcher bags frequently for wear
or deterioration. For safety protection replace
only with new bag meeting original equip
ment specifications.
27. Look behind to make sure the area is clear

MAINTENANCE
CRANKCASE OIL
I WARNING \
Remove the spark plug lead before
performing any maintenance on the
machine.
a. Oil Check
Check the oil level in the crankcase before each
use of the machine and after every two hours of
operation. Keep the oil level to the overflovving
point. See figure 16.
Step 1. With the machine on level ground, place a
suitable metal container under the oil
drain plug located on the front of the
engine. See figure 17.
Step 2. After the oil has been drained completely
from the crankcase, replace the drain plug
and tighten.
Step 3. With the machine on level ground, remove
the oil filler plug. See figure 16. Fill the
crankcase until the oil overflows from the
oil fill hole. Fill slowly to avoid air locks.
The crankcase holds approximately 1 %
pints of good quality SAE 30 type MS
engine oil. Replace the oil filler plug.
b. Oil Change
After the first two hours of operating a new
engine, drain the oil from the crankcase while the
engine is stili hot and refiil the crankcase with
new oil; thereafter, change the oil after every 25
hours of operation. This procedure ensures for
minimum wear of engine parts and provides for
virtually trouble-free operation. To change the oil,
proceed as follows:
FIGURE 17. OIL DRAIN
a. Steering Gears. Lubricate with multi-purpose
automotive type grease once a season.
b. Front Wheel Bearings. Remove the front axle
bolts and coat the axle with a multi-purpose
automotive type grease and reassemble once a
season. See figure 18.
c. King Pins. Lubricate the king pins after every
25 hours of operation with SAE 30 oil. Wipe up
excessive oil with a rag. See figure 18.
d. Rear Axle Bearings. Lubricate the rear axle
bearings after every 25 hours of operation with
SAE 30 oil. Wipe up excessive oil with a rag.
See figure 19.
e. Chain. Remove thé chain once each season,
clean in kerosene, dry and lubricate with a rag
saturated in SAE 30 ojl. See figure 19.
f. Transmission. The transmission has been lu
bricated at the factory and does not need to be
checked.
