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  
immediately.  
Proper maintenance is critical to the safety and performance of your unit.  
Be sure to perform the maintenance procedures listed in this manual,  
especially periodically testing the safety system.

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.  
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

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.  
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.  
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  
downhill.  
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 steep 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.  
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.  
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  
recommendations of wheel weights or  
counterweights to improve stability.  
EMISSIONS  
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.  
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  
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.

mower cutting height. The mower cutting height can be  
set to one of seven positions between 1-1/4” and 4.”  
The Reverse Mowing Option allows for mowing (or use  
of other PTO driven attachments) while traveling in  
reverse. If you choose to mow in reverse, turn the RMO  
key after the PTO is engaged. The L.E.D. light will  
illuminate, and the operator can then mow in reverse.  
Each time the PTO is engaged the RMO needs to be  
reactivated if desired.  
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.

Troubleshooting,  
Adjustment, & Service  
Troubleshooting  
WARNING  
To avoid serious injury, perform maintenance on  
the tractor or mower only when the engine is  
stopped and the parking brake engaged.  
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.  
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  
instructions on how to perform most of these minor  
adjustments and service repairs yourself. If you prefer,

*Briggs & Stratton Models: The gross power rating for individual gas engine models is labeled in accordance with  
SAE (Society of Automotive Engineers) code J1940 (Small Engine Power & Torque Rating Procedure), and rating  
performance has been obtained and corrected in accordance with SAE J1995 (Revision 2002-05). Torque values are  
derived at 3060 RPM; horsepower values are derived at 3600 RPM. Actual gross engine power will be lower and is  
affected by, among other things, ambient operating conditions and engine-to-engine variability. Given both the wide  
array of products on which engines are placed and the variety of environmental issues applicable to operating the  
equipment, the gas engine will not develop the rated gross power when used in a given piece of power equipment  
(actual "on-site" or net horsepower). This difference is due to a variety of factors including, but not limited to,  
accessories (air cleaner, exhaust, charging, cooling, carburetor, fuel pump, etc.), application limitations, ambient  
operating conditions (temperature, humidity, altitude), and engine-to-engine variability. Due to manufacturing and  
capacity limitations, Briggs & Stratton may substitute an engine of higher rated power for this Series engine.
