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 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.
f
• 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.
