B. SLOPE OPERATION
Slopes are a major factor related to loss of control and tip-over accidents, which can result in
severe injur y or death.
All
slopes require extra
caution. If you cannot back up the slope
or if you feel uneasy on it, do not mow it.
For your safety, use the slope gauge included as
a part of this manual (see pg. 27) to measure
slopes before operating this unit on a sloped or
hilly area. If the slope is greater than 15 degrees
as shown on the slope gauge, do not operate this
unit on that area or serious injury could result.
DO:
• Mow across slopes, not up and down.
• Remove obstacles such as rocks, limbs, etc.
• Watch for holes , ruts or bumps. Uneven terrain
could overturn the machine.
T all grass can hide
obstacles.
• Use slow speed. Choose a low enough speed
so that you will not have to stop while on the
slope.
• Follow the manufacture’s recommendat ion s for
counterweights with attachments to improve stability.
• Use extra care with grass catchers or other
attachments. These can change the stability of
the machine.
• Keep all movement on the slopes
slow
and
gradual.
Do not make sudden changes in speed
or direction. Rapid acceleration or deceleration
could cause the front of the machine to lift and
rapidly flip over backwards, which could cause
serious injury.
• Avoid starting or stopping on a slope. If the
tires lose traction, disengage the blades and proceed slowly
straight
down the slope.
DO NOT :
•
Do not
turn on slopes unless necessar y ; then,
turn slowly and use extra care.
• Do not
mow near drop-offs, ditches or embankments. The mower could suddenly turn over if a
wheel is over the edge of a cliff or ditch, or if an
edge caves in.
•
Do not
mow on wet grass. Reduced traction
could cause sliding.
• Do not
try to stabilize the machine by putting
your foot on the ground.
• Do not
use the grass catcher on steep slopes.
C. CHILDREN
Tragic accidents can occur if the operator is not
alert to the presence of children. Children are
often attracted to the machine and the mowing
activity.
Never
assume that children will
remain where you last saw them.
1. Keep children out of the mowing area
and in wat chf ul care o f a n adul t other t ha n the
operator.
2. Be alert and turn the machine off if children
ente r the area.
3. Befor e and whe n bac k ing up , look beh ind a nd
down
for small children.
4. Nev er c arry chi ldre n, even with the blades of f .
They may fall of f and be seriously injured or
may interfere with safe machine operation.
5. Never allow children under 14 years old to
operate the machine. Children 14 years and
over should only op erate th e m achine under
close pare ntal supervision and p roper instruction.
6. Use e xt ra care when approaching blind corners, shrub s, trees or othe r objects that may
obscure your vision of a chi l d or ot her hazard.

OPE RATING IN ST R U CT ION S
A. General
1. When Mo wi n g:
a. Keep adults, children, and pets away from
the area to be mowed.
b. When operating this mower, in the forward
direction, do not allow the steering levers
to return to neutral on their own. Always
maintain a firm grip on the lev ers, operate
them smoothly and avoid any sudden
movements of the lev ers when s tarting and
stopping.
c. If the mower is equipped for side dis-
charge, never use the mower without the
discharge chute installed and placed in the
down position.
d. Always remove debris and other objects
from the area to be mowed (Note: debris
and loose grass will reduce traction).
e. Mow only in daylight or good ar t ificial light.
f. Watch f or holes, sprinkler heads, and other
hidden hazards.
g. Avoid driving too close to trees, creeks,
ditches, sand traps, and other obstacles.
h. Before backing up, check behind and
watch where you are going.
i. Always reduce speed when making a turn,
and when grass is wet.
j. Always mow across slopes, never up and
down the slope. Do not operate on steep
slopes and slow down before turning.
Avoid tur ning downhill if possible, start at
the bottom and work up to the top. Use
extra care and go slowly when turning
downhill. Control the speed and direction
of the zero turn machine “primarily” with
the speed/directional control (lap bar) of
the down hill s id e o f the machine...I .E.,
maintain the uphill side lap bar “essentially” in a fixed position.
k. Be careful when crossing gravel paths or
roadways. Always turn off the blade clutch
switch and wait until the blades stop rotating and raise the cutting deck to the transport position. Always allow other vehicles
to have the right of way.
l. If you hit a solid object while mowing, turn
off the blade clutch switch, place the steering levers in the neutral, opened-out position, move the throttle to slow, set the
parking brake, shut off the engine, and
take the key from the ignition switch.
Inspect for damage. Repair the damage.
Make sure the blades are in good condition
and that the blade bolts are tight before
restarting the engine.
m. Nev er leave t he mower unattended without
performing the following: turn off the blade
clutch switch, placing the steering levers i n
the neutral open-out position, moving the
throttle to slow, setting the parking brake,
shutting off the engine and taking the key
from the ignition switch.
n. Never walk or stand on the discharge side
of the mower when the engine is running.
Tur n off the blade clutch switch if another
person approaches while you are operating the mower.
o. Never attempt to operate the traction unit
without having the mowing deck attached.
p. Keep the mower and especially the engine
and hydraulic components clean and free
of grease, grass, and leaves to reduce the
chance of fire and permit proper cooling.

2. Safety Awareness when M owing
a. Do not operate on steep slopes, those
above 15 degrees (27% slope).
b. Avoid turning downhill if possible, use extra
care and go slowly .
c. Avoid turning when going downhill, traction
is at a minimum going downhill.
d. Do not operate with discharge side of the
mowe r toward streets, bu i l ding s , play-
grounds, parking lots, other machines, ani-
mals, and other people.
e. Avoid operation or use extreme care if the
traction surface is wet, unstable, or slip-
pery.
f. Use extra care when grass clippings,
leaves, pine needles, or debris are present
as traction can be reduced.
g. Slow-down before turn ing and come to a
complete stop before any zero t urn maneu-
ver.
h. Do not stop machine or park machine over
combustible materials such as dry grass,
leaves, debris, etc.
3. To Mow Grass and Produce a Striped P attern
a. Pick a point on the opposite side of the
area to be mowed (post, tree, shrub, etc.).
b. I f on a h ills i d e, sta rt at the bott om so that
the turns are uphill rather than downhill.
c. Align the mower so as to head directly
toward the object on the far side.
d. Slowly increase the speed of the machine
to match cutting conditions, terrain, and
operator familiarity with the controls and
keep the machine headed directly toward
the alignment object. Do not go fast as to
reduce cut quality or to be uncomfortable
in controlling the speed and direction of the
machine.
e. When approaching the other end of a strip,
slow down or stop before turning. A U-turn
is recommended unless a zero turn is
required. The speed of a U-turn that will
allow for machine controllability and minimal turf defacement will be dependent on
several factors including: the speed during
turning, the radius of the turn, the tire tread
pattern, the traction coefficient of the tire to
the traction surface, the slope of the traction surface.
f. Remem ber, a zero turn requires that the
forward or reverse travel of the machine be
stopped prior to the initiation of the turn or
severe turf defacement can occur.
g. To prevent rutting or grooving of the turf,
change the direction that the strips are
mowed by approximately 45 degrees the
next and each subsequent time that the
area is mowed.
B. Controls
