O UNAM AAA NENA
As a general rule, never cut more than 1/3 off the
height of the grass. If you want the grass shorter,
~ wait a few days then recut to the lower height. If cut
the grass will use more energy for
too “short,
development of new leaf structure and less for a
. healthy root system and will be more subject to bur- -
ning. On the other hand, if allowed to grow too long,
the lower portion will be shaded and, as a result will
discolor. In dry periods, allow the grass to grow
longer than you normally would. Change your mow-
ing pattern from time to time for a smoother cut
lawn.
‘CUTTING HEIG HT ADJUSTMENT
Positioning the axles in the lowest of the four adjust-
ment positions in the wheel brackets raises the cut-
ting deck to the highest cutting height which is
about 3”. The top position provides the lowest cut of
about 1”. Repositioning into the next height of cut
position changes cutting height about 2/3rds of an
inch. '
Readjust cutting height with engine shut off as
follows: To reposition front axle, push down on
mower handles to raise front wheels off the ground
“then pull in on one of the spring loaded bushings un-
til it clears the bracket, move to the desired height of
cut position and release the bushing. Repeat pro-
cedure on bushing on other side of axle. When
repositioning rear axle, lift handles to raise one of
the rear wheels off ground then change axle position
using same procedure as used on front axle. Repeat
~ same procedure on other rear wheel. NOTE: Make
sure axle bushings are firmly engaged and in the
same height of cut position in the brackets on both
‘sides of axle.

RECYCLING MOWER OPERATION
For best results when recycling, set the cutting
height in notch 5 (highest blade setting) or notch 4°
and mow with the engine speed control In fastest
speed setting. Operate the mower at slowest ground
. speed to allow fine chopping of the clippings or
leaves. The grass must be dry. If the grass 'Is ex-
- tremely dense, set the front height adjusters one
: notch lower than the rear adjusters to ralse the front
of the deck. Experiment with deck settings to
_achleve best recycling.
“WARNING: DO NOT operate mower without the
recycling cover installed on the mower deck! If the
cover ls removed for side discharging or bagging,
always install the proper side discharge chute or

cumulations of grass with putty knife and/or wire
brush first, then wash down with water from a hose.
CAUTION: Avoid spraying water into exhaust or air
intake of engine while washing deck - tape openings
closed to prevent this. Clean external surfaces of
mower and allow to dry, then lubricate all exposed
metal surfaces with a light coat of oil to prevent cor-
rosion. Make sure grass bag is completely emptied

SERVICE a
~The mower itself requires very little service, however, it is very important that the engine be serviced at the inter-
vals specified. in the engine manual furnished with your mower. When performing any service on the mower, —
always disconnect the spark plug wire from the spark plug to prevent unintentional starting. When tipping the
mower to work on the underside, always tilt with spark plug up to prevent flooding the engine with gasoline or oil
which would cause hard starting after servicing. NOTE: If engine will not start, check bag adapter or side chute to
determine that either item is properly positioned on mower. = ~ ВЕ | | В i
