Safety Rules and Information  
SLOPE OPERATION  
WARNING  
Slopes are a major factor related to loss-of-control and tip-  
over 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.  
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 rear-  
mounted 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.  
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 distri-  
bution.  
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.  
CHILDREN  
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.  
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.  
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 embank-  
ments. 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 recommenda-  
tions 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.  
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.  
TOWED EQUIPMENT (RIDE-ON UNITS)  
IGNITION SYSTEM  
1. Tow only with a machine that has a hitch designed for  
towing. Do not attach towed equipment except at the  
hitch point.  
1. This spark ignition system complies with Canadian  
ICES-002.  
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 equip-  
ment.  
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.

with a plastic bed liner. Always place containers on  
the ground away from your vehicle before filling.  
7. Remove gas-powered equipment from the truck or  
trailer and refuel it on the ground. If this is not possi-  
ble, then refuel such equipment on a trailer with a  
portable container, rather than from a gasoline dis-  
penser nozzle.  
8. Keep nozzle in contact with the rim of the fuel tank or  
container opening at all times until fueling is com-  
plete. Do not use a nozzle lock-open device.  
9. If fuel is spilled on clothing, change clothing immedi-  
ately.  
10. Never over-fill the fuel tank. Replace gas cap and  
tighten securely.

unit vibrates abnormally. After striking an object,  
inspect the machine for damage and make repairs  
before restarting and operating the equipment.  
23. Never place hands near the moving parts, such as a  
hydro pump cooling fan, when the tractor is running.  
(Hydro pump cooling fans are typically located on top  
of the transaxle).  
11. Use extra care in handling gasoline and other fuels.  
They are flammable and vapors are explosive.  
12. If fuel is spilled, do not attempt to start the engine but  
move the machine away from the area of spillage and  
avoid creating any source of ignition until fuel vapors  
have dissipated.  
24. Units with hydraulic pumps, hoses, or motors: WARN-  
ING: Hydraulic fluid escaping under pressure may  
have sufficient force to penetrate skin and cause seri-  
ous injury. If foreign fluid is injected into the skin it  
must be surgically removed within a few hours by a  
doctor familiar with this form of injury or gangrene  
may result. Keep body and hands away from pin  
holes or nozzles that eject hydraulic fluid under high  
pressure. Use paper or cardboard, and not hands, to  
search for leaks. Make sure all hydraulic fluid con-  
nections are tight and all hydraulic hoses and lines  
are in good condition before applying pressure to the  
system. If leaks occur, have the unit serviced imme-  
diately by your authorized dealer.  
25. WARNING: Stored energy device. Improper release  
of springs can result in serious personal injury.  
Springs should be removed by an authorized techni-  
cian.  
26. Models equipped with an engine radiator: WARNING:  
Stored energy device. To prevent serious bodily injury  
from hot coolant or steam blow-out, never attempt to  
remove the radiator cap while the engine is running.  
Stop the engine and wait until it is cool. Even then,  
use extreme care when removing the cap.  
13. Replace all fuel tank caps and fuel container caps  
securely.

Features & Controls  
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.  
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.  
Throttle Control  
The throttle controls engine speed. Move the throttle for-  
ward to increase engine speed and back to decrease  
engine speed. Always operate at FULL throttle.  
Moving a lever forward increases the FORWARD speed  
of the associated wheel, and pulling back on a lever  
increases the REVERSE speed.  
Choke  
Close the choke for cold starting. Open the choke once  
the engine starts. A warm engine may not require chok-  
ing. Move the lever forward to close the choke. Move the  
lever back to open the choke.  
The further a lever is moved away from the neutral posi-  
tion the faster the drive wheel will turn.  
See the OPERATION section for steering instructions.

simultaneously, and lower the mower into cutting posi-  
tion.  
START  
Cranks the engine for starting.  
NOTE: Never leave the ignition switch in the RUN posi-  
tion with the engine stopped–this drains the battery.  
Hour Meter / Maintenance Reminder  
The hour meter measures the number of hours the key  
has been in the RUN position. The hour meter will flash  
an initial oil change indicator at 5 hours, and a lubrication  
reminder every 50 hours. These reminders display for  
approximately two hours and will automatically reset  
themselves.  
For attachment transport lift, pull the large lift lever back  
fully to lock the control in the attachment raised transport  
position.  
Parking Brake  
Note: The hour meter will register the passage of time  
when the key is in the RUN position, even if the engine is  
not running. The hour meter has a self contained power  
source so the total hours are always visible.

gages attachments that use the PTO. To engage the  
PTO, pull UP on the switch. Push DOWN to disengage.  
Note that the operator must be seated firmly in the rider  
seat for the PTO to function.  
Transmission Oil Fill  
Transmission oil is added through the transmission oil  
expansion chamber. It also serves as extra holding  
capacity for oil as the transmission heats up and the oil  
expands. See CHECK TRANSMISSION OIL LEVEL for  
oil level check and fill procedures.  
Transmission Release Valves  
The transmission release valves deactivate the transmis-  
sions so that the unit can be pushed by hand. See  
PUSHING THE UNIT BY HAND for operational informa-  
tion.  
Seat Adjustment Lever  
The seat can be adjusted forward and backward. Move  
the adjustment lever towards the left, slide the seat to the  
desired position, and release the lever.

rider’s forward, reverse, and turning movements will take  
some practice.  
The BEST method of  
handling the ground  
speed control levers is in  
three steps — as shown  
in Figure 3.  
Spending some time going through the maneuvers  
shown and becoming familiar with how the unit acceler-  
ates, travels, and steers — before you begin mowing —is  
absolutely essential to getting the most out of the zero  
turn rider.  
FIRST place your hands  
onto the levers as  
shown.  
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.  
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.  
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.  
Figure 3. Move Control  
Levers Gradually  
BASIC DRIVING  
Forward Travel Practice  
Reverse Travel Practice  
Gradually move both ground speed control levers —  
evenly FORWARD from neutral. Slow down and repeat.  
LOOK DOWN & BEHIND, then gradually move both  
ground speed control levers evenly BACK from neutral.  
Slow down and repeat.  
NOTE: Straight forward travel takes practice. If neces-  
sary, top speed can be balance-adjusted — see the  
Speed Balancing Adjustment in the Adjustments section  
near the back of this manual.  
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.

Practice Turning Around a Corner  
Practice Turning In Place  
While traveling forward allow one handle to gradually  
return back toward neutral. Repeat several times.  
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: To prevent pivoting directly on the tire tread, it is  
best to keep both wheels going at least slightly forward.  
NOTE: Changing the amount each lever is pulled—for-  
ward or back, changes the “pivot point” you turn on.

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 Y-  
turn 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 experi-  
enced 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 bet-  
ter your control of the rider will be!

ATTACHING A TRAILER  
The maximum weight of a towed trailer should be less  
than 200 lbs (91kg). Secure the trailer with an appropri-  
ately sized clevis pin (A, Figure 9) and clip (B).  
A
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 operat-  
ing 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 manu-  
al for additional safety information.

CHECK TIRE PRESSURES  
Tire pressure should be checked periodically, and main-  
tained 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:

Pressure  
40 psi (2,76 bar)  
15 psi (1,03 bar)  
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.  
Figure 17. Checking Tire Pressure  
NOTE: Do not overfill. Refer to your engine manual for  
specific fuel recommendations.  
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.  
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).  
Do not use gasoline containing METHANOL,  
gasohol containing more than 10% ethanol,  
gasoline additives, premium gasoline, or white  
gas because engine/fuel system damage  
could result.  
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.

the system.  
WARNING  
Be careful when handling the battery. Avoid  
spilling electrolyte. Keep flames and sparks away  
from the battery.  
When removing or installing battery cables,  
disconnect the negative cable FIRST and reconnect  
it LAST. If not done in this order, the positive  
terminal can be shorted to the frame by a tool.  
BATTERY MAINTENANCE  
Cleaning the Battery and Cables  
1. Disconnect the cables from the battery, negative  
cable first (B, Figure 19).  
2. Clean the battery terminals and cable ends with a  
wire brush until shiny.  
3. Reinstall the battery and reattach the battery cables,  
positive cable first (see A, Figure 19)  
WARNING  
Never store the unit (with fuel) in an enclosed,  
poorly ventilated structure. Fuel vapors can  
travel to an ignition source (such as a furnace,  
water heater, etc.) and cause an explosion.  
4. Coat the cable ends and battery terminals with petro-  
leum jelly or non-conducting grease.  
STORAGE  
Before you store your unit for the off-season, read the  
Maintenance and Storage instructions in the Safety  
Rules section, then perform the following steps:  
Fuel vapor is also toxic to humans and animals.  
• Battery life will be increased if it is removed, put in a  
cool, dry place and fully charged about once a  
month. If the battery is left in the unit, disconnect the  
negative cable.  
• Disengage the PTO, set the parking brake, & remove  
the key.  
• Perform engine maintenance and storage measures  
listed in the engine owner’s manual. This includes  
draining the fuel system, or adding stabilizer to the  
fuel (do not store a fueled unit in an enclosed struc-  
ture - see warning).  
Before starting the unit after it has been stored:  
• Check all fluid levels. Check all maintenance items.  
• Perform all recommended checks and procedures  
found in the engine owner’s manual.  
• Allow the engine to warm up for several minutes  
before use.

Troubleshooting,  
Adjustments, & Service  
TROUBLESHOOTING  
While normal care and regular maintenance will extend  
the life of your equipment, prolonged or constant use  
may eventually require that service be performed to allow  
it to continue operating properly.  
WARNING  
To avoid serious injury, perform maintenance on  
the rider or mower only when the engine is  
stopped and the parking brake engaged.  
Always remove the ignition key, disconnect the  
spark plug wire and fasten it away from the plug  
before beginning the maintenance, to prevent  
accidental starting of the engine.  
The troubleshooting guide below lists the most common  
problems, their causes and remedies.

3. Check the brake spring (A, Figure 24) length (both  
wheels). With the brake engaged the compressed  
spring length should be 2” (5 cm). If not, adjust the  
locknut (C, Figure 24) to achieve the compressed  
spring length of 2” (5 cm).

4. After achieving the correct spring compression, check  
the set collar gap (B, Figure 24). With the parking  
brake engaged, the set collar gap should be 3/16"  
(5 mm). If not, loosen the set collar screw and move  
the collar to the correct position.

PTO CLUTCH ADJUSTMENT  
WARNING  
To avoid serious injury, perform adjustments only  
with engine stopped, key removed and rider on  
level ground.  
Check the PTO clutch adjustment after the initial 25 hour  
break-in period and then after every 100 hours of opera-  
tion. 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 acciden-  
tal starting while the PTO is being adjusted.  
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.  
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).  
1. With parking brake engaged, PTO disengaged and  
an operator in the seat, start the engine engine.  
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.  
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 sec-  
onds. Disengage the PTO and check the amount of  
time it takes for the mower drive belt to stop.  
4. Alternately tighten the adjustment nuts (B, Figure 25)  
until the rotor face and armature face just contacts  
the gauge.  
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.  
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 loosen-  
ing the adjustment nuts.  
NOTE: The actual air gap between the rotor and arma-  
ture may vary even after performing the adjustment pro-  
cedure. This is due to dimensional variations on compo-  
nent parts, and is an acceptable condition.  
6. Check the mower blade stopping time. The mower  
blades and mower drive belt should come to a com-  
plete stop within five (5) seconds after the electric  
PTO switch is turned off.

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).  
Figure 27. Orient Blades Side-to-Side  
A
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.

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.  
B
C
8. Check the length of the hanging rods. The rear (D,  
Figure 29) should be 15” (38,1cm) and is not adjust-  
ed. 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) counter-  
clockwise 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 ten-  
sion on both leveling nuts.
