performance.

section
of this
manual.
°
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 resuIt in a more even distri_
bution 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 (See Fig_ 11).

(
if grass is extremely tall, it should be mowed twice
to reduce load and possibFe fire hazard from dried
clippings° Make first cut relatively high; the second
to the desired heighL
°
Do not mow grass when it is weL
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 attachment being used.
MULCHING
MOWING TIPS
IMPORTANT:
FOR BEST PERFORMANCE,
KEEP
MOWER HOUSING FREE OF BUILT-UP GRASS AND
TRASH., CLEAN AFTER EACH USE.
=
The special mulching blade will recut the grass clip-
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_ Also, the mulched grass will
biodegrade quickly to provide nutrients for the lawn.
Always mulch with your highest engine (blade) speed
as this will provide the best recutting action of the
blades.
=
Avoid cutting your lawn when it is wet, Wet grass tends
to form clumps and interferes with the mulching action.
The best time to mow your' lawn is the early afternoon.
At this time the grass has dried and the newly cut area
will not be exposed to the direct sun1,
°
For best results, adjust the mower cutting height so that
the mower cuts off only the top one-third of the grass
blades (See Fig, 12). For extremely heavy mulching,
reduce your width of cut on each pass and mow slowly.

MAX 1/3
.
Certain types of grass and grass conditions may re-
quire that an area be mulched a second time to com-
pletely hide the clippings. When doing a second cut,
mow across or perpendicular to tile first cut path.
o
Change your cutting pattern from week to week° Mow
north to south one week then change to east to west the
next week. This will help prevent matting and grairiing
of the lawn.
