Safety Rules & Information  
Operating Safety  
Congratulations on purchasing a superior-quality piece of lawn and  
garden equipment. Our products are designed and manufactured to  
meet or exceed all industry standards for safety.  
Power equipment is only as safe as the operator. If it is misused, or  
not properly maintained, it can be dangerous! Remember, you are  
responsible for your safety and that of those around you.  
Use common sense, and think through what you are doing. If you  
are not sure that the task you are about to perform can be safely  
done with the equipment you have chosen, ask a  
professional: contact your local authorized dealer.  
Read the Manual  
The operator’s manual contains important safety information you need to be aware of  
BEFORE you operate your unit as well as DURING operation.  
Safe operating techniques, an explanation of the product’s features and  
controls, and maintenance information is included to help you get the  
most out of your equipment investment.  
Be sure to completely read the Safety Rules and Information found on  
the following pages. Also completely read the Operation section.  
Children  
Reverse  
Tragic accidents can occur with children. Do not allow  
them anywhere near the area of operation. Children are  
often attracted to the unit and mowing activity. Never  
assume that children will remain where you last saw them.  
If there is a risk that children may enter the area where you  
are mowing, have another responsible adult watch them.  
Do not mow in reverse unless  
absolutely necessary. Always look  
down and behind before and  
while traveling in reverse  
even with the mower  
blades disengaged.  
DO NOT GIVE CHILDREN RIDES ON THIS UNIT! This  
encourages them to come near the unit in the future while it  
is running, and they could be seriously hurt. They may then  
approach the unit for a ride when you are not expecting it,  
and you may run over them.  
TP 600-2459-08-UV-SMA

Safety Rules and Information  
Slope Operation  
You could be seriously injured or even killed if you use this unit on too  
steep an incline. Using the unit on a slope that is too steep or where  
you don’t have adequate traction can cause you to lose control or roll  
over.  
A good rule of thumb is to not operate on any slope you cannot back up  
(in 2-wheel drive mode). You should not operate on inclines with a  
slope greater than a 3.5 foot rise over a 20 foot length. Always drive up  
and down slopes: never cross the face.  
Also note that the surface you are driving on can greatly impact stability  
and control. Wet grass or icy pavement can seriously affect your ability  
to control the unit.  
If you feel unsure about operating the unit on an incline, don’t do it. It’s  
not worth the risk.  
Moving Parts  
This equipment has many moving parts that can injure you or someone else.  
However, if you are seated in the seat properly, and follow all the rules in this  
book, the unit is safe to operate.  
The mower deck has spinning mower blades that can amputate hands and feet.  
Do not allow anyone near the equipment while it is running!  
To help you, the operator, use this equipment safely, it is equipped with an  
operator-present safety system. Do NOT attempt to alter or bypass the system.  
See your dealer immediately if the system does not pass all the safety interlock  
system tests found in this manual.  
Thrown Objects  
This unit has spinning mower blades. These blades can pick up and throw  
debris that could seriously injure a bystander. Be sure to clean up the area to  
be mowed BEFORE you start mowing.  
Do not operate this unit without the entire grass catcher or discharge guard  
(deflector) in place.  
Also, do not allow anyone in the area while the unit is running! If someone  
does enter the area, shut the unit off immediately until they leave.  
Fuel and Maintenance  
Gasoline is extremely flammable. Its vapors are also extremely flammable  
and can travel to distant ignition sources. Gasoline must only be used as a  
fuel, not as a solvent or cleaner. It should never be stored any place where  
its vapors can build up or travel to an ignition source like a pilot light. Fuel  
belongs in an approved, plastic, sealed gas can, or in the tractor fuel tank  
with the cap securely closed. Spilled fuel needs to be cleaned up immedi-  
ately.  
Proper maintenance is critical to the safety and performance of your unit.  
Be sure to perform the maintenance procedures listed in this manual, espe-  
cially periodically testing the safety system.

practical instruction.  
22. Always wear substantial footwear and trousers.  
Never operate when barefoot or wearing sandals.  
23. Before using, always visually check that the blades  
and blade hardware are present, intact, and secure.  
Replace worn or damaged parts.  
24. Disengage attachments before: refueling, removing  
an attachment, making adjustments (unless the  
adjustment can be made from the operator’s posi-  
tion).  
25. When the machine is parked, stored, or left unattend-  
ed, lower the cutting means unless a positive  
mechanical lock is used.  
26. Before leaving the operator’s position for any reason,  
engage the parking brake (if equipped), disengage  
the PTO, stop the engine, and remove the key.  
27. To reduce fire hazard, keep the unit free of grass,  
leaves, & excess oil. Do not stop or park over dry  
leaves, grass, or combustible materials.  
28. It is a violation of California Public Resource Code  
Section 4442 to use or operate the engine on or near  
any forest-covered, brush-covered, or grass-covered  
land unless the exhaust system is equipped with a  
spark arrester meeting any applicable local or state  
laws. Other states or federal areas may have similar  
laws.  
8. Never direct discharge material toward anyone.  
Avoid discharging material against a wall or obstruc-  
tion. Material may ricochet back toward the operator.  
Stop the blade(s) when crossing gravel surfaces.  
9. Do not operate the machine without the entire grass  
catcher, discharge guard (deflector), or other safety  
devices in place.  
10. Slow down before turning.  
11. Never leave a running unit unattended. Always disen-  
gage the PTO, set parking brake, stop engine, and  
remove keys before dismounting.

storage preparations before storing the unit for both  
short and long term periods.  
5. Always follow the engine manual instructions for  
proper start-up procedures when returning the unit to  
service.  
6. Never store the unit or fuel container inside where  
there is an open flame or pilot light, such as in a  
water heater. Allow unit to cool before storing.  
1. When transporting the unit on an open trailer, make  
sure it is facing forward, in the direction of travel. If  
the unit is facing backwards, wind lift could damage  
the unit.  
2. Always observe safe refueling and fuel handling prac-  
tices when refueling the unit after transportation or  
storage.  
3. 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. Fuel vapor is also toxic to  
humans and animals.

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 can-  
not 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 distrib-  
ution.  
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.  
When operating on slopes use additional wheel  
weights or counterweights. See your dealer/retailer  
to determine which weights are available and  
appropriate for your unit.  
Select slow ground speed before driving onto slope.  
In addition to front weights, use extra caution when  
operating on slopes with rear-mounted grass  
catchers.  
Mow UP and DOWN the slope, never across the  
face, use caution when changing directions and DO  
NOT START OR STOP ON SLOPE.  
1. Mow up and down slopes, not across.  
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. Always keep unit in gear especially when traveling  
down slopes. Do not shift to neutral and coast down-  
hill.  
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.  
6. Avoid starting, stopping, or turning on a slope. If tires  
lose traction, disengage the blade(s) and proceed  
slowly straight down the slope.  
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.  
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 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 downhill, if possible.  
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.  
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.  
IGNITION SYSTEM  
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.  
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.

removed for clarity  
Please take a moment and  
familiarize yourself with  
the name, location, and  
function of these controls  
so that you will better  
12V  
understand the safety and  
operating instructions pro-  
vided in this manual.  
CONTROL FUNCTIONS  
The information below briefly describes the func-  
tion of individual controls. Starting, stopping, dri-  
ving, and mowing require the combined use of sev-  
eral controls applied in specific sequences. To  
learn what combination and sequence of controls  
to use for various tasks see the OPERATION sec-  
tion.  
Choke  
Throttle/Choke Control  
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.  
(Single Lever Models)  
The throttle/choke lever controls engine speed and  
choke. Move the throttle forward to increase engine  
speed and back to decrease engine speed. Always  
operate at FULL throttle. Move the control fully forward  
(past the detent) to close the choke. Close the choke for  
cold starting. Open the choke once the engine starts. A  
warm engine may not require choking.  
Headlights  
The light switch turns the tractor headlights on and off.  
Hour Meter (Optional)  
The hour meter registers hours of use.  
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.

Features & Controls  
PTO Switch  
Catcher Removal Lock  
After depressing the catcher dump lock pedal, pull this  
knob forward to release the catcher for removal.  
The PTO (Power Take-Off) switch engages and disen-  
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 trac-  
tor seat for the PTO to function.  
Cruise Control (Optional)  
The cruise control is used to lock the ground speed con-  
trol in forward. Move the lever forward until the desired  
ground speed is reached. To disengage the cruise con-  
trol move the lever back. In the event you need to stop  
quickly, depressing the brake pedal will also return the  
cruise control to neutral.  
Ignition Switch  
The ignition switch starts and stops the engine, it has  
three positions:  
OFF  
Stops the engine and shuts off the  
electrical system.  
Seat Adjustment Lever  
The seat can be adjusted forward and back. Move the  
lever, position the seat as desired, and release the lever  
to lock the seat into position.  
RUN  
Allows the engine to run and powers the  
electrical system.  
START

NOTE: Never leave the ignition switch in the RUN posi-  
tion with the engine stopped–this drains the battery.  
Transmission Release Valve Lever  
The transmission release valve lever deactivates the  
transmission so that the tractor can be pushed by hand.  
See PUSHING THE TRACTOR BY HAND for opera-  
tional information.  
Ground Speed Pedals  
The tractor’s forward ground speed is controlled by the  
forward ground speed control pedal. The tractor’s  
reverse ground speed is controlled by the reverse  
ground speed control pedal.  
Catcher-Full Alarm  
The “catcher full” alarm sounds when the grass catcher  
has been filled with cut grass. When the alarm sounds,  
disengage the PTO, travel to the area in which you  
desire to dump the grass, then empty the catcher. Note:  
When using the unit for leaf collection, the alarm may not  
be activated by dry leaves.  
Depressing either pedal will increase ground speed.  
Note that the further down the pedal is depressed, the  
faster the tractor will travel.  
Mower Height of Cut Adjustment  
The cutting height adjustment knob controls the mower  
cutting height. The cutting height is infinitely adjustable  
between 1” and 3-3/4” (2.5cm-9.5cm).  
Fuel Tank / Fuel Gauge  
The fuel gage indicates the amount of fuel in the fuel  
tank. To add fuel, remove the filler cap. Be sure to  
leave room for heat expansion.  
Cutting Height Fine Tuning Adjustment  
The cutting height fine tuning adjustment is used to set  
the mower cutting height between two of the preset cut-  
ting positions.  
Parking Brake  
The parking brake knob is used to lock the parking brake  
when the tractor is stopped. Fully depressing the brake  
pedal and pulling up on the knob engages the parking  
brake. Refer to page 12 for a full explanation of parking  
brake functions.  
Attachment Lift Control Lever

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 tractor 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.  
See the information on the following pages for instruc-  
tions on how to perform most of these minor adjustments  
and service repairs yourself. If you prefer, all of these  
procedures can be performed for you by your local

Specifications  
NOTE: Specifications are correct at time of printing and are subject to change without notice.  
* The power ratings for an individual engine model are initially developed by starting with SAE (Society of Automotive  
Engineers) code J1940 (Small Engine Power & Torque Rating Procedure) (Revision 2002–05). Given both the wide  
array of products on which our engines are placed, and the variety of environmental issues applicable to operating  
the equipment, it may be that the engine you have purchased will not develop the rated horsepower when used in a  
piece of power equipment (actual “on–site” power). This difference is due to a variety of factors including, but not lim-  
ited to, the following: differences in altitude, temperature, barometric pressure, humidity, fuel, engine lubrication, max-  
imum governed engine speed, individual engine to engine variability, design of the particular piece of power equip-  
ment, the manner in which the engine is operated, engine run–in to reduce friction and clean out of combustion  
chambers, adjustments to the valves and carburetor, and other factors. The power ratings may also be adjusted  
based on comparisons to other similar engines utilized in similar applications, and will therefore not necessarily match  
the values derived using the foregoing codes.
