TO START ENGINE
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.
1. Sit on seat in operating position,
depress clutch/brake pedal and set
parking brake.
2. Place gear shift lever in neutral posi­
tion.
3. Move attachment clutch to disengaged
position.
4. Move throttle control to choke position.
NOTE: Before starting, read the warm
and cold starting procedures below.
5. 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 seconds 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 /10°
C and above)
6. 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 /10°
C and below)
7. When engine starts, leave throttle
control in choke position until engine
warms up and begins to run roughly.
Once rough running begins, immedi­
ately move the throttle control to the
fast position. Engine warm-up may
take from several seconds to several
minutes (the colder the temperature,
the longer the warm-up).
• The attachments can also be used dur­
ing 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 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.
• The left hand side of mower should be
used for trimming.
• Drive so that clippings are discharged
onto the area that has already been
cut. Have the cut area to the right of
the tractor. This will result in a more
even distribution 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.

If grass is extremely tall, it should be
mowed twice to reduce load and pos­
sible fire hazard from dried clippings.
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 mowing to
assure better mowing
performance and proper discharge of
material. Regulate ground speed by
selecting a low enough speed to give
the mower cutting performance 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
tachment being used.
