OPERATION

TO START ENGINE (See Fig. 11)

When starting the engine for the first time or if the engine

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

fuel from the tank to the engine.

Sit on seat in operating position, depress clutch/brake

pedal and set parking brake.

• Place gear shift lever in neutral position.
• Move attachment clutch to “DISENGAGED” position.
• Move throttle control to choke position.
NOTE: Before starting, read the warm and cold starting

procedures below.

Insert key into ignition and turn key clockwise to “START”

position and release key as soon as engine starts.

Do not run starter continuously for more than fifteen

sec onds per minute. If the engine does not start after

several attempts, move throttle control to fast position,

wait a few minutes and try again. If engine still does

not start, move the throttle control back to the choke

position and retry.

WARM WEATHER STARTING (50° F and above)

• When engine starts, move the throttle control to the

fast position.

The attachments and ground drive can now be used. If

the engine does not accept the load, restart the engine

and allow it to warm up for one minute using the choke

as described above.

COLD WEATHER STARTING (50° F and below)
• When engine starts, allow engine to run with the

throttle control in the choke position until the engine

runs roughly, then move throttle control to fast posi-

tion. This may require an engine warm-up period from

several seconds to several minutes, depending on the

tem per a ture.

• The attachments can also be used during the engine

warm-up period.

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 hous ing

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.

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 dis tri bu 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. 11).

FIG. 11

• If grass is extremely tall, it should be mowed twice to

reduce load and possible fire hazard from dried clip-

pings. Make first cut relatively high; the second to the

desired height.

• Do not mow grass when it is wet. Wet grass will plug

mower and leave undesirable clumps. Allow grass to

dry before mowing.

Always operate engine at full throttle when mow-

ing to assure better mowing performance and proper

dis charge of material. Regulate ground speed by

se lect ing a low enough gear to give the mower cut ting

per for mance as well as the quality of cut desired.

• When operating attachments, select a ground speed

that will suit the terrain and give best performance of

the at tach ment being used.
