MOWINGTIPS
Mower should be propedy leveled for
best mowingperformance. 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 been cut. Have
the cut area to the right of the tractor.
This will result in a more even distribu-
tion of clippingsand more uniform
cutting.
When mowing large areas, start by
turningto the right sothat clippingswill
discharge away from shrubs,fences,
driveways, etc. After one ortwo
rounds, mow in the opposite direction
making left hand turns untilfinished.
If grass is extremely tall, it should be
mowed twice to reduce load and
possible fire hazard from dried clip-
pings. Make firstcut relativelyhigh; the
second to the desired height.
, Do not mow grass when it iswet. Wet
grass will plug mower and leave
undesirable clumps. Allow grass to dry
before mowing.

when mowing to assure bettermowing
performance and proper discharge of
material. Regalate 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
attachment being used.
