best performance is obtained with the trans-
mission in 'Iowtt range and the engine run-
ning approximately 3/4 throttle. The throttle
should be set as low as practical to obtain
maximum fuel economy but high enough to
prevent engine lug-down or laborwhichcould
cause overheating and poor mowing. Ad-

LOOK FOR THIS SYMBOL
TO POINT OUT IMPORTANT
SAFETY PRECAUTIONS
Regard your rotary mower as a piece of
power equipment and be surethismanual
is read and understood by all who op-

Clear the lawn or area to be mowed of
sticks, stones or any hard objects which
could come in contact with the blades
and be hurled out the discharge opening.
Do not permit children or pets in the
area while mowing.
KEEP FEET AND HANDS AWAY FROM
DISCHARGE OPENING AND MAKE NO
REPAIRS UNLESS BOTH THE TRACTOR
ENGINE AND PTO ARE SHUT OFF.
Fill gas tank out of doors and avoid

OPERATING METHODS AND TIPS
1.
2
Keep mower blades sharp andbalanced as
covered in Adjustments and Maintenance
Section.
Operate engine at approximately 3/4
throttle and regulate the ground speed
Travel Lever according to mowing con-
ditions. As a general rule, set the
throttle as low as practical to obtain
maximum fuel economy but high enough
to avoid engine lug-down or labor which
could cause overheating. Unless grass
is unusually light, always operate in
rrl€w?? speed range.
If grass is heavy and higherthannormal,
results can be improvedby mowing twice.
Make the first cut with the mower set
higher than normal; then repeat with the
mower set at desired finished cutheight.
When mowing heavy grass, always dis-
charge clippings away from the uncut
area.
Figures 2 and 3 illustrate two systems
for mowing. If the grass is high or
heavy, always mow to throw the clip-
pings away from the uncut area, Figure
2. If the grass is tight and more thor-
ough mulching is desired, discharge the
clippings toward the center of the uncut
area, Figure 3. When mowing in this
manner, a final strip of mulched clip-
pings about three to four feet wide wiII
remain near the center of the lawn. This
can be easily raked up to leave a weII
groomed appearance.
Trimming will be neater and closer by
using the right side of the mower since
the clippings will be discharged away
from the object. Also the safety shield
over the discharge opening prevents
mowing as close to objects.
Do not step on the mower deck when
getting on or off the tractor. If mounting
the tractor from the right side, place
your right foot on the right foot rest,
your right hand on steering wheel and
left hand on the seat back and step onto
the tractor, swinging your left foot
through between the steering wheel and
seal"
When mounting from the left side, start
with your left foot on the left foot rest,
your left hand on steering wheel and
right hand on seat back and step onto
tractor swinging your right foot through
between steering wheel and seat.
