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
cuL 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 operatingattachments, select a
ground speed that will suit the terrain
and give best performance of the at-
tachment being used.
