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.
