OPERATION

ADD GASOUNE

• Fill fuel tank. Use fresh, clean, regular unleaded

gasoline. (Use of leaded gasoline will increase carbon

and lead oxide deposits and reduce valve life).

IMPORTANT: WHEN OPERATING ¡N TEMPERATURES
BELOW 32“F(0°C), USE FRESH, CLEAN WINTER GRADE
GASOLINE TO HELP INSURE GOOD COLD WEATHER
STARTING.
WARNING; Experience indicates that alcohol blended
fuels (called gasohol or using ethanol or methanol) can

attract moisture which leads to separation and formation of

acids during storage. Acidic gas can damage the fuel
system of an engine while in storage. To avoid engine
probiems, the fuel system should be emptied before stor­
age of 30 days or longer. Drain the gas tank, start the

engine and let it run until the fuel lines and carburetor are
empty. Use fresh fuel next season. See Storage Instruc­
tions for additional information. Never use engine or
carburetor cleaner products in the fuel tank or permanent
damage may occur.

TO START ENGINE (See Fig. 11)

When starting engine for the first time or if engine has

run out of fuel, it will take extra cranking time to move

fuel from the tank to the engine.

Depress the clutch/brake pedal and set the parking

brake,

Place gearshift lever in “NEUTRAL” position.

®

Move attachment clutch to

“DISENGAGED” position.

® Pull choke control out to “CHOKE” position for cold

engine start. For warm engine start do not use choke
control.

® Move throttle control to midway between “FAST” and

“SLOW” positions.

® Turn ignition key clockwise to “START” position and

release key as soon as engine starts. Do not run

starter continuously for more than fifteen seconds
per minute, if engine does not start after several
attempts, move throttle control to “FAST" position,
wait a few minutes and try again.

When engine starts, slowly push choke control in.

® Move throttle control to “FAST” position.

® Allow engine to warm up for a few minutes before

engaging clutch/brake pedal or attachment clutch
switch.

NOTE: If at a high altitude (above 3000 feet) or in cold

temperatures (below 32° 'F), the carburetor fuel mixture

may need to be adjusted for best engine performance.
See ‘TO ADJUST CARBURETOR” in the Service and

Adjustments section of this manual.

MOWING TIPS

® Tire chains cannot be used when the mower housing

is attached to tractor.

Mower should be properly leveled for best mowing

performance. See ‘TO LEVEL MOWER HOUSING”
in the Service and Adjustments section of this
manual.

Use the runner on the right hand side of mower as

a guide. The blade cuts approximately an inch out­
side the runner (See Fig. 12).

« The left hand side of mower should be used for trim­

ming.

® Drive so that clippings are discharged onto the area

that has been cut. Have the cut area to the right of
the tractor. This will result in a more even distribu­
tion of clippings and more uniform cutting.

When mowing large areas, start by turning to the

right so that clippings will discharge away from

shrubs, fences, driveways, etc. After one or two

rounds, mow in the opposite direction making left
hand turns until finished (See Fig. 14).

® If grass is extremely tall, it should be mowed twice

to reduce load and possible fire hazard from dried
clippings. Make first cut relatively high; the second
to the desired height.

Do not mow grass when it is wet. Wei grass will

plug mower and leave undesirable clumps. Allow
grass to dry before mov/ing.

® Always operate engine at full throttle when mowing

to assure better mowing performance and proper
discharge of material. Regulate ground speed by
selecting a tow enough gear to give the mower cut­
ting performance as well as the quality of cut de­
sired.

When operating attachments, select a ground speed

that will suit the terrain and give best performance of
the attachment being used.
