COLD WEATHER STARTiNG ( 50° F and
beiow)
6. When engine starts, leave throttle
control in choke position until engine
warms up and begins to run roughly.
Once rough running begins, imme­
diately 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
• Mower should be properly leveled for
best mowing performance. See “TO
LEVEL MOWER HOUSING” in the
Service and Adjustments section of this
manual.
• The ¡eft 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 gear 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.
MULCHING MOWING TIPS
IMPORTANT: For best performance, keep
mower housing free of built-up grass and
trash. Clean after each use.
® The special mulching blade will recut
the grass clippings many times and
reduce them in size so that as they fall
onto the lawn they will disperse into
the grass and not be noticed. Also, the
mulched grass will biodegrade quickly
to provide nutrients for the lawn. Always
mulch with your highest engine (blade)
speed as this will provide the best recut­
ting action of the blades.
<» Avoid cutting your lawn when it is wet.
Wet grass tends to form clumps and
interferes with the mulching action. The
best time to mow your lawn is the early
afternoon. At this time the grass has
dried, the newly cut area will not be
exposed to direct sunlight.
• For best results, adjust the mower
cutting height so that the mower cuts
off only the top one-third of the grass
blades. For extremely heavy grass, re­
duce your width of cut on each pass and
mow slowly.

Certain types of grass and grass
conditions may require that an area be
mulched a second time to completely
hide the clippings. When doing a sec­
ond cut, mow across (perpendicular) to
the first cut path.
Change your cutting pattern from week
to week. Mow north to south one week
then change to east to west the next
week. This will help prevent matting and
graining of the lawn.
