PJace gearshift lever in neutral (N) position,
Move attachment dutch to "DISENGAGED"
position.
o
Pull choke control out to choke
3osition for cold
engine start, For warm engine
not use choke
control.
o
Move throttle controJ to midway between fast (@) and
slow (_)
positions.

o
Allow engine to warm up for a few minutes before
engaging drive or attachments.
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 Adjust-
ments section of this manual.
MOWmNG TiPS
Tire chains cannot be used when the mower housing
is attached to tractor.
o
Mower should be properly leveled for best mowing
performance.
See "TO LEVEL MOWER HOUSING" in
the Service and Adjustments
section of this manual.
o
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
machine. This will result in a more even distribution of
clippings and more uniform cutting.
o
When mowing large areas, start by turning to the right
so that cJippings wilt 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. 10 ).
o
If grass is extremely tall, it should be mowed twice to
reduce toad and possible fire hazard from dried clip-
pings. Make first cut relatively high; the second to the
desired height°
o
Do not mow grass when it is wet. Wet grass will plug
mower and _eave undesirabb
clumps. AHow grass to
dry before mowing.
o
Always operate engine at full throttle when mowing to
assure be_er mowing performance
and proper dis °
charge of material.
Regulate ground speed by select o
ing a _ow enough
gear to give the mower cutting
performance as well as the quality of cut desired.

o
When operating attachments,
select a ground speed
that will suit the terrain and give best performance
of
the attachment being used.

pings 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.
AJso, the mulched grass will
biodegrade quickly to provide nutrients for the Jawn.
Always mulch with your highest engine (blade) speed
as this will provide the best recutting action of the
blades.
o
Avoid cutting your lawn when it is wet Wet grass tends
to form dumps and interferes with the mulching action.
The best time to mow your fawn is the early afternoon.
At this time the grass has dried and the newly cut area
wilJ not be exposed to the direct sun.
o
For best results, adjust the mower cutting height so that
the mower cuts off only the top oneothird of the grass
blades (See Fig tl}o For extremely heavy mulching,
reduce your width of cut on each pass and mow stowly.

o
Certain types of grass and grass conditions may re-
quire that an area be mu_ched a second time to com-
pletely hide the clippingso When doing a second cut,
mow across or 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 witl he_p prevent matting and graining
of the lawno
