CHILDREN
Tragic accidents can occur if the operator is not alert to the
presence of children. Children are often attracted to the unit
and the mowing activity. Never assume that children will
remain where you last saw them.
1. Keep children out of the mowing area and under the
watchful care of another responsible adult.
2. Be alert and turn unit off if children enter the area.
3. Before and during reverse operation, look behind and
down for small children.
4. Never carry children, even with the blade(s) off. They
may fall off and be seriously injured or interfere with
safe unit operation. Children who have been given
rides in the past may suddenly appear in the mowing
area for another ride and be run over or backed over
by the machine.
5. Never allow children to operate the unit.
6. Use extra care when approaching blind corners,
shrubs, trees, or other objects that may obscure
vision.
EMISSIONS
1. Engine exhaust from this product contains chemicals
known, in certain quantities, to cause cancer, birth
defects, or other reproductive harm.
2. Look for the relevant Emissions Durability Period and
Air Index information on the engine emissions label.
IGNITION SYSTEM
1. This spark ignition system coplies with Canadian
ICES-002.
SLOPE OPERATION
Slopes are a major factor related to loss-of-control and tipover accidents, which can result in severe injury or death.
Operation on all slopes requires extra caution. If you cannot
back up the slope or if you feel uneasy on it, do not operate
on it.
Control of a walk-behind or ride-on machine sliding on a
slope will not be regained by the application of the brake.
The main reasons for loss of control are: insufficient tire
grip on the ground, speed too fast, inadequate braking, the
type of machine is unsuitable for its task, lack of awareness
of the ground conditions, incorrect hitching and load distribution.
1. Mow across the face of slopes, not up and down.
2. Watch for holes, ruts, or bumps. Uneven terrain could
overturn the unit. Tall grass can hide obstacles.
3. Choose a slow speed so that you will not have to stop
or change speeds while on the slope.
4. Do not mow on wet grass. Tires may loose traction.
5. Never mow down slopes.
6. Avoid starting, stopping, or turning on a slope. If tires
lose traction (i.e. machine stops forward motion on a
slope), disengage the blade(s) (PTO) and drive slow
off the slope.
7. Keep all movement on slopes slow and gradual. Do
not make sudden changes in speed or direction,
which could cause the machine to rollover.
8. Use extra care while operating machines with grass
catchers or other attachments; they can affect the
stability of the unit. Do not use on steeps slopes.
9. Do not try to stabilize the machine by putting your
foot on the ground (ride-on units).
10. 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.
11. Do not use grass catchers on steep slopes.
12. Do not mow slopes if you cannot back up them.
13. See your authorized dealer/retailer for recommendations of wheel weights or counterweights to improve
stability.
14. Remove obstacles such as rocks, tree limbs, etc.
15. Use slow speed. Tires may lose traction on slopes
even through the brakes are functioning properly.
16. Do not turn on slopes unless necessary, and then,
turn slowly and gradually uphill, if possible. Never
mow down slopes.
TOWED EQUIPMENT (RIDE-ON UNITS)
1. Tow only with a machine that has a hitch designed for
towing. Do not attach towed equipment except at the
hitch point.
2. Follow the manufacturer’s recommendations for
weight limit for towed equipment and towing on
slopes. See attaching a trailer under OPERATION.
3. Never allow children or others in or on towed equipment.
4. On slopes, the weight of the towed equipment may
cause loss of traction and loss of control.
5. Travel slowly and allow extra distance to stop.
6. Do not shift to neutral and coast down hill.
WARNING
Never operate on slopes greater than 17.6 percent
(10°) which is a rise of 3-1/2 feet (106 cm) vertically in
20 feet (607 cm) horizontally.
Select slow ground speed before driving onto slope.
Use extra caution when operating on slopes with rearmounted grass catchers.
Mow across the face of slopes, not up and down,use
caution when changing directions and DO NOT
START OR STOP ON SLOPE.

Ground Speed Levers
These levers control the ground speed of the rider. The
left lever controls the left rear drive wheel and the right
controls the right rear drive wheel.
Moving a lever forward increases the FORWARD speed
of the associated wheel, and pulling back on a lever
increases the REVERSE speed.
The further a lever is moved away from the neutral position the faster the drive wheel will turn.
See the OPERATION section for steering instructions.
Throttle Control
The throttle controls engine speed. Move the throttle forward to increase engine speed and back to decrease
engine speed. Always operate at FULL throttle.
Choke
Close the choke for cold starting. Open the choke once
the engine starts. A warm engine may not require choking. Move the lever forward to close the choke. Move the
lever back to open the choke.
CONTROL FUNCTIONS
The information below briefly describes the function of individual controls. Starting, stopping, driving, and mowing
require the combined use of several controls applied in specific sequences. To learn what combination and sequence
of controls to use for various tasks see the OPERATION section.

ZERO TURN
DRIVING PRACTICE
The lever controls of the zero turn rider are responsive,
and learning to gain a smooth and efficient control of the
rider’s forward, reverse, and turning movements will take
some practice.
Spending some time going through the maneuvers
shown and becoming familiar with how the unit accelerates, travels, and steers — before you begin mowing —is
absolutely essential to getting the most out of the zero
turn rider.
Locate a smooth, flat area of your lawn — one with
plenty of room to maneuver. (Clear the area of objects,
people and animals before you begin.) Operate the unit
at mid-throttle during this practice session (ALWAYS
operate at full throttle when mowing), and turn slowly to
prevent tire slippage and damage to your lawn.
We suggest you begin with the Smooth Travel procedure
to the right, and then advance through the forward,
reverse, and turning maneuvers.
You must release the parking brake prior to moving the
control levers inward.
BASIC DRIVING
Forward Travel Practice
Gradually move both ground speed control levers —
evenly FORWARD from neutral. Slow down and repeat.
NOTE: Straight forward travel takes practice. If necessary, top speed can be balance-adjusted — see the
Speed Balancing Adjustment in the Adjustments section
near the back of this manual.
Reverse Travel Practice
LOOK DOWN & BEHIND, then gradually move both
ground speed control levers evenly BACK from neutral.
Slow down and repeat.
NOTE: Practice backing up for several minutes before
attempting to do so near objects. The rider turns as
sharply in reverse as when going forward, and backing
up straight takes practice.

three steps — as shown
in Figure 3.
FIRST place your hands
onto the levers as
shown.
SECOND, to go forward
gradually push the levers
forward with your palms.
THIRD, to speed up
move the levers farther
forward. To slow down
smoothly, slowly move
the levers toward neutral.

ADVANCED DRIVING
Executing an End-Of-Row Zero
Turn
Your zero turn rider’s unique ability to turn in
place allows you to turn around at the end of
a cutting row rather than having to stop and Yturn before starting a new row.
For example, to execute a right end-of row
zero turn:
1. Slow down at the end of the row.
2. Move the LEFT ground speed control
lever forward slightly while moving the
RIGHT ground speed control lever back to
center and then slightly back from center.
3. Begin mowing forward again.
This technique turns the rider RIGHT and
slightly overlaps the row just cut —eliminating
the need to back up and re-cut missed grass.
As you become more familiar and experienced with operating the zero turn rider, you
will learn more maneuvers that will make your
mowing time easier and more enjoyable.
Remember, the more you practice, the better your control of the rider will be!
Practice Turning Around a Corner
While traveling forward allow one handle to gradually
return back toward neutral. Repeat several times.
NOTE: To prevent pivoting directly on the tire tread, it is
best to keep both wheels going at least slightly forward.

ATTACHING A TRAILER
The maximum weight of a towed trailer should be less
than 200 lbs (91kg). Secure the trailer with an appropriately sized clevis pin (A, Figure 9) and clip (B).
Excessive towed loads can cause loss of traction and
loss of control on slopes. Reduce towed weight when
operating on slopes. The surface being driven on greatly
impacts traction and stability. Wet or slippery surfaces
can greatly reduce traction and the ability to stop or turn.
Carefully evaluate the surface conditions before operating the unit and trailer, and never operate on slopes
greater than 10°. See SLOPE OPERATION and TOWED
EQUIPMENT in the safety section of this manual for
additional safety information.

CUTTING HEIGHT ADJUSTMENT
The cutting height adjustment pin (A, Figure 22) controls
the mower cutting height. The cutting height is
adjustable between 1-1/2” (3,8 cm) and 4-1/2” (11,4cm).
Pulling the lever back fully locks the control in transport
position.
To adjust cutting height:
1. Pull the adjustment lever (B, Figure 22) back fully
until it locks in transport position.
2. Remove the cutting height adjustment pin (A) and
insert it into the desired hole.
3. Pull back on the adjustment lever (B), squeeze the
smaller transport release lever (C), and allow the
lever to move forward until it is supported by the cutting height adjustment pin (A).
ROLLER BAR ADJUSTMENT
The rollers on this Zero Turn unit are not intended to ride
on the ground. DO NOT adjust rollers to ride on the
ground. Rollers riding on the ground will damage turf and
or unit.
NEUTRAL ADJUSTMENT
If the unit creeps forward or backward with the control
levers in their neutral positions, see your dealer.

FRONT SUSPENSION ADJUSTMENT
(SELECT MODELS)
The shock assembly can be adjusted to vary the amount
of pre-load applied to the springs. This allows the operator to customize the ride according to operator’s weight
and operating conditions.
LESS PRE-LOAD:
• Light operator weight
• Softer, more cushioned ride
• Best for relatively flat terrain
MORE PRE-LOAD:
• Heavy operator weight
• Stiffer, more rigid ride
• Better handling and greater stability on hilly terrain
TO ADJUST THE SPRING PRE-LOAD:
1. Park machine on a flat, level surface. Disengage the
PTO, stop the engine and engage the parking brake.
2. See Figure 24. Turn the pre-load adjustment collar
(A) CLOCKWISE to increase the pre-load, turn
COUNTER-CLOCKWISE to decrease the pre-load.
Make sure both shocks are set to the same amount
of pre-load.

PTO CLUTCH ADJUSTMENT
Check the PTO clutch adjustment after the initial 25 hour
break-in period and then after every 250 hours of operation. Also perform the following procedure if the clutch is
slipping or will not engage, or if a new clutch has been
installed.
1. Remove key from ignition switch and disconnect
spark plug wires to prevent the possibility of accidental starting while the PTO is being adjusted.
2. See Figure 25. Note the position of the 3 adjustment
windows (A) in the side of the brake plate and the
nylock adjustment nuts (B).
3. Insert a .016”-.018” (0,40-0,45mm) feeler gauge (C)
through each window, positioning the gauge between
the rotor face and the armature face as shown in
Figure 26.
4. Alternately tighten the adjustment nuts (B, Figure 25)
until the rotor face and armature face just contacts
the gauge.
5. Check the windows for an equal amount of tension
when the gauge is inserted and removed, and make
any necessary adjustments by tightening or loosening the adjustment nuts.
NOTE: The actual air gap between the rotor and armature may vary even after performing the adjustment procedure. This is due to dimensional variations on component parts, and is an acceptable condition.
6. Check the mower blade stopping time. The mower
blades and mower drive belt should come to a complete stop within five seconds after the electric PTO
switch is turned off.
BLADE BRAKE CHECK
Mower blades and mower drive belt should come to a
complete stop within five seconds after electric PTO
switch is turned off.
1. With parking brake engaged, PTO disengaged and
an operator in the seat, start the engine engine.
2. Have an assistant observe the mower drive belt
through the opening between the frame and top of
mower deck. Engage the PTO and wait several seconds. Disengage the PTO and check the amount of
time it takes for the mower drive belt to stop.
3. If the mower drive belt does not stop within five seconds, perform the PTO Clutch Adjustment. If the belt
still does not stop within 5 seconds, see your dealer.

MOWER DECK LEVELING
Perform these adjustments on a flat level surface.
Note: Do not adjust the mower lift height rod (H, Figure
29) as it will effect the mower deck lift height.
SIDE-TO-SIDE LEVELING
1. With the mower installed, place the rider on a
smooth, level surface such as a concrete floor. Turn
the front wheels so they are straight.
2. Check for bent blades and replace if necessary.
3. Place the mower cutting height pin in the 4th hole
from the bottom (C, Figure 29). Arrange the
outside mower blades so that they are pointing from
side-to-side (Figure 27).
4. Measure the distance between the outside tips of
each blade and the ground (Figures 27 & 28). If there
is more than 1/8” (3mm) difference between the
measurements on each side, proceed to step 5. If the
difference is 1/8” (3mm) or less, proceed to step 6.
5. Use the rear leveling rods (B, Figure 29) to adjust the
side-to-side leveling of the deck. Repeat step 4 if
necessary.
FRONT-TO-BACK LEVELING
6. Arrange the blades so they face front-to-back (Figure
30).
7. Measure the distance from the ground to the front tip
of the center blade, and from the ground to rear tips
of left-hand and right-hand blades (Figures 28 & 30).
The front tip of the center blade should be 1/4" (6mm)
higher than rear tips of left-hand and right-hand
blades. If not, proceed with steps 8 - 11.
8. Check the length of the hanging rods: the rear (D,
Figure 29) should be 15” (38,1cm) and is not adjusted. The front rods (E) should be initially adjusted to
14-3/4” (37,5cm). To adjust the pitch of the mower
deck, adjust the front pitch rods only.
9. To lower the front of mower deck, loosen the set collars (F, Figure 29) and slide towards the mower deck,
loosen the jam nuts (A) and adjust the clevises out.
Reverse this to raise the front of the mower. Be sure
to raise or lower both clevis the same amount.

HOW AND WHEN TO
WATER, FERTILIZE &
AERATE
Most lawns are watered too often,
but with too little water. However
too much water can allow development of diseases with your lawn. It is
best to water the lawn only when
necessary, and then to water it
slowly, evenly, and deeply—imitating a slow, soaking rain.
WHEN TO WATER YOUR LAWN
When the lawn begins to wilt, the grass’s color dulls, or
footprints stay compressed for more than a few seconds,
the lawn is beginning to dry out, and needs additional
moisture. The best time to water is early morning to allow
the water to soak deeply into the lawn and reduce the
amount that evaporates in the hot afternoon sun.
HOW TO WATER YOUR LAWN
The best method of watering a lawn
is to imitate a slow, soaking rain,
applying about 1 inch of water.
HOW TO FERTILIZE YOUR LAWN
Fertilizing with a slow-release fertilizer provides missing nutrients which
help create slow, even growth.
Remember that over-fertilizing can
cause harm, and that most fertilizing
should be applied in the spring so
that it will release into the lawn
through the summer.
AERATING YOUR LAWN
Consider aerating your lawn in spring. Using an aerator
to remove cores of soil from the lawn increases the
speed of clipping decomposition and encourages deeper
root growth by opening up the soil and permitting greater
movement of water, fertilizer and air.
TP 600-2136-03-UV-SMA
HOW HIGH TO MOW THE GRASS
Cutting the grass too short causes weak, thin
grass plants, which are easily damaged by dry
periods and pests.
Letting grass grow a bit longer—especially when it
is hot and dry—reduces heat build-up, preserves
needed moisture and protects the grass from heat
damage and other problems.
Cutting off too much at one time shocks the plant’s
growth system and weakens the grass plants. A
good rule of thumb is the 1/3 rule: to cut no
more than one third of the grass height, and
never more than 1 inch at a time.

Tall Grass Requires Incremental Cutting
For extremely tall grass, set the cutting height at maximum for the first pass, and then reset it to the desired
height and mow a second or third time.
Don’t cover the grass surface with a heavy layer of
clippings.

area contributes to

Lawn Care & Mowing Information
WHEN AND HOW OFTEN TO MOW
The time of day and condition of the grass greatly affect the results you’ll
get when mowing. For the best results, follow these guidelines:
● Mow when the grass is between 3”-4” (7,5-10 cm) high.
● Mow with sharp blades. Short clippings of grass one inch or shorter
decompose more quickly than longer blades. Sharp mower blades cut
grass cleanly and efficiently, preventing frayed edges which harm the
grass.
● Mow at time of day when the grass is cool and dry. Late afternoon or
early evening often provide these ideal mowing conditions.
● Avoid mowing after rain or even heavy dew, and never mulch when the
grass is wet (moist grass does not mulch well, and clumps beneath the
mower deck).
Note: Always operate the engine at full throttle when mowing.
PROPER MOWING SPEED
ENGINE SPEED & GROUND SPEED
Always operate the engine at full throttle when mowing.
If you hear the engine slowing down, you are mowing too
fast—maintaining a slower ground speed will improve the
cutting efficiency of the blades and prevents many common cutting problems.
Select an appropriate ground speed for the thickness
and height of the grass you are cutting (3rd gear or slower for manual gear models, or mid-range or slower for
hydro models). If you hear the engine slowing down you
are mowing too fast, use a slower ground speed.
HOW MUCH GRASS TO CUT OFF
Mow when the grass is 3”-4” inches (7,5-10cm) long. Do
not cut off more that 1” (2.5cm) of grass in a single pass.
