2. Look for the relevant Emissions Durability Period and
Air Index information on the engine emissions label.
IGNITION SYSTEM
1. This spark ignition system complies 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 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.

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.

speed control levers is in
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.

Figure 8. Executing an End-Of-Row Turn
Practice Turning In Place
To turn in place, “zero turn,” gradually move one ground
speed control lever forward from neutral and one lever
back from neutral simultaneously. Repeat several times.
NOTE: Changing the amount each lever is pulled—forward or back, changes the “pivot point” you turn on.

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 that 10 degrees. See SLOPE OPERATION and
TOWED EQUIPMENT in the safety section of this manual for additional safety information.

CHECK TIRE PRESSURES
Tire pressure should be checked periodically, and maintained at the levels shown in the chart. Note that these
pressures may differ slightly from the “Max Inflation”
stamped on the side-wall of the tires. The pressures
shown provide proper traction, improve cut quality, and
extend tire life.
CHECKING / ADDING FUEL
To add fuel:
1. Remove the fuel cap (see A, Figure 18).
2. Fill the tank to the bottom of the filler neck. This will
allow for fuel expansion.
NOTE: Do not overfill. Refer to your engine manual for
specific fuel recommendations.
3. Install and hand tighten the fuel cap.
FUEL FILTER
The fuel filter is located in the fuel line between fuel tank
and fuel pump. If the filter is dirty or clogged, replace as
follows:
1. Disconnect the negative battery cable.
2. Place a container below the filter to catch spilled fuel.
3. Using a pliers, open and slide hose clamps from fuel
filter (C, Figure 18).
4. Remove hoses from filter.
5. Install new filter in proper flow direction in fuel line.
6. Secure with hose clamps.
7. Reconnect the negative battery cable when finished.
ENGINE MAINTENANCE
Refer to engine owners manual for all engine maintenance procedures and recommendations.
CHECK /FILL TRANSMISSION OIL
Oil Type: Mobil 1™ 15W-50 synthetic oil, Castrol
Syntec™ 5W-50 oil, or 20W-50 conventional detergent
motor oil.
1. Check the oil level when the unit is cold. The inspection port is located on the inside of the right tank
cover. The oil level should be within 1/2” (1.3 cm) of
the horizontal level mark (D, Figure 19). If the oil is
below this level, proceed to step 2.
2. Before removing the reservoir cap, make sure the
area around the reservoir cap and fill neck of the
reservoir is free of dust, dirt, or other debris. Loosen
the locking capscrew (E, Figure 18) securing the locking tab (D), slide the lock tab back, and remove the
cap (B).
3. Add oil up to the full mark (D, Figure 19).
WARNING
Gasoline is highly flammable and must be
handled with care. Never fill the tank when the
engine is still hot from recent operation. Do not
allow open flame, smoking or matches in the area.
Avoid over-filling and wipe up any spills.
Do not remove fuel filter when engine is hot, as
spilled gasoline may ignite. DO NOT spread hose
clamps further than necessary. Ensure clamps
grip hoses firmly over filter after installation.
Do not use gasoline containing METHANOL,
gasohol containing more than 10% ethanol,
gasoline additives, premium gasoline, or white

PTO CLUTCH ADJUSTMENT
Check the PTO clutch adjustment after the initial 25 hour
break-in period and then after every 100 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 (5) 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 (5) 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 (5)
seconds, perform the PTO Clutch Adjustment. If the
belt still does not stop within five (5) seconds, see
your dealer.

MOWER DECK LEVELING
Perform these adjustments on a flat level surface.
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 (see insert, 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 links (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. To adjust the pitch of the mower deck, adjust the
front leveling nuts only.
9. Loosen the front lock nuts (E, Figure 29).
10. Turn the leveling nuts (A, Figure 29) counterclockwise to lower the front of mower deck. Turn the
nuts clockwise to raise the front of the mower. Make
adjustments in small increments, trying to keep tension on both leveling nuts.
11. Tighten the front lock nuts (E).
12. Re-check the blade measurement then repeat steps
7-11 as necessary.

BATTERY CHARGING
A dead battery or one too weak to start the engine may
be the result of a defect in the charging system or other
electrical component. If there is any doubt about the
cause of the problem, see your dealer. If you need to
replace the battery, follow the steps under Cleaning the
Battery & Cables in the Regular Maintenance Section.
To charge the battery, follow the instructions provided by
the battery charger manufacturer as well as all warnings
included in the safety rules sections of this book. Charge
the battery until fully charged (until the specific gravity of
the electrolyte is 1.250 or higher and the electrolyte temperature is at least 60° F). Do not charge at a rate higher
than 10 amps.
WARNING
Keep open flames and sparks away from the
battery; the gasses coming from it are highly
explosive. Ventilate the battery well during
charging.
