Operator Safety

Operating Safety
Power equipment is only as safe as the operator. If it is misused, or
not properly maintained, it can be dangerous! Remember, you areresponsible 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 aprofessional: contact your local authorized dealer.

Read the Manual
The operator’s manual contains important safety information you need to beaware of BEFORE you operate your unit as well as DURING operation.

N
ep oro t fo

Safe operating techniques, an explanation of the product’s features andcontrols, and maintenance information is included to help you get themost out of your equipment investment.

RBe sure to completely read the Safety Rules and Information foundon the following pages. Also completely read the Operation section.

ChildrenReverseTragic 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 thatchildren will remain where you last saw them. If there is arisk 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 withthe mower blades disengaged.

DO NOT GIVE CHILDREN RIDES ON THIS UNIT! Thisencourages them to come near the unit in the future while itis running, and they could be seriously hurt. They may thenapproach the unit for a ride when you are not expecting it,
and you may run over them.

Operator Safety

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 ft (1,5 m) rise over a 20.0 ft (6,0 m) 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 PartsN
ep oro t fo
du r
ct
io
n

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, theunit 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 operatorpresent safety system. Do NOT attempt to alter or bypass the system. See yourdealer immediately if the system does not pass all the safety interlock systemtests 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.

R

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 MaintenanceGasoline is extremely flammable. Its vapors are also extremely flammable andcan 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.

Protection against Tipovers

Tragic accidents can occur if the operator is not alert to thepresence of children. Children are often attracted to themachine and the mowing activity. 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 themachine. Never assume that children will remain where you
last saw them.
1. KEEP children out of the mowing area and under thewatchful care of a responsible adult other than the operator.
2. DO NOT allow children in yard when machine is operated(even with the blade OFF).
3. DO NOT allow children or others to ride on machine,
attachments or towed equipment (even with the bladesOFF). They may fall and be seriously injured.
4. DO NOT allow pre-teenage children to operate machine.
5. ALLOW only responsible adults & teenagers with mature
judgment under close adult supervision to operate machine.
6. DO NOT operate blades in reverse. STOP BLADES. LOOK
and SEE behind and down for children, pets and hazards
before and while backing.
7. USE EXTRA CARE when approaching blind corners,
shrubs, trees, or other objects that may obscure vision.

(Continued From Previous Column)
6. KEEP A SAFE DISTANCE (at least 3 feet) away from edgeof ditches and other drop offs. The machine could turn over
if an edge caves in.
7. Always begin forward motion slowly and with caution.
8. Use weights or a weighted load carrier in accordancewith instructions supplied with a grass catcher. DO NOT
operate machine on slopes exceeding 10 degrees (18%
grade) when equipped with grass catcher.
9. DO NOT put your foot on the ground to try to stabilize
the machine.
10. DO NOT operate machine on wet grass. Reduced traction could cause sliding.

Reverse Lockout Mechanism
Data indicates that tragic back-over accidents occur eachyear. These accidents usually involve unsupervised children.
Many times these children have been given rides on themachine and have been trained to view this potentially dangerous piece of machinery as fun rather than being taught
how to avoid danger.

1. Stop the machine. Stop the blade.
2. Depress and hold the Override Lever.
3. Depress and hold the Blade Pedals. Release theOverride Lever.
4. Move the blade lever forward to “ON” position.

WARNINGLOOK and SEE behind and down for children, pets andhazards before and while backing.

We realize that this could cause a change to your previous
mowing method but we encourage you to adjust to this new
system. Do not defeat the Reverse Lockout Mechanism.

!

DANGER!

LOOK and SEE behind and down for children, pets andhazards before and while backing.
BLADES must be turned off before backing machine.
DO NOT allow children on machine (even with blades off)
or in yard when mowing.

R

If you operate your mower near roadways or use attachments that require quicker shifting to reverse, there is anoverride lever provided. This lever can be pushed and held
before starting the blade and will allow reverse operation
until the blade pedals are released, at which time the system
will return to its Reverse Lockout mode. This feature should
never be selected unless you are absolutely sure that no children or others are present in the mowing area and that all
children are away and supervised by a responsible adult.

!

IMPORTANT: DO NOT use the Reverse Lockout Mechanism
Override as the normal operating mode. To return to the
Reverse Lockout Mechanism mode, release blade pedals toturn blade off. The Override will reset to Reverse Lockout.
Check the Reverse Lockout Mechanism frequently for proper
function. With the blade pedals depressed, the shift levermust not go into reverse. DO NOT operate machine if
Reverse Lockout Mechanism is not functioning properly.
Contact your local Snapper dealer for assistance.

This riding mower has a Reverse Lockout Mechanism. Thismechanism prevents the mower from being shifted into
reverse with the blade running. To shift into reverse you
must first stop the blade by releasing the blade pedals andthen shift to reverse. It is our recommendation that thismechanism remain functional and the operator of this equipment develop the habit of never backing up with the blade
running. As the Safety Instructions Indicate, DO NOT operate blades in reverse. STOP BLADES, LOOK AND SEE
BEHIND AND DOWN for children, pets and hazards before

Product Specifications

R* Power Rating
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 inaccordance with SAE J1995 (Revision 2002-05). Torque values are derived at 3060 RPM; horsepower values are derived at
3600 RPM. The gross power curves can be viewed at www.BRIGGSandSTRATTON.COM. Net power values are taken withexhaust and air cleaner installed whereas gross power values are collected without these attachments. Actual gross engine
power will be higher than net engine power and is affected by, among other things, ambient operating conditions and engineto-engine variability. Given the wide array of products on which engines are placed, the gas engine may not develop the rated
gross power when used in a given piece of power equipment. This difference is due to a variety of factors including, but notlimited to, the variety of engine components (air cleaner, exhaust, charging, cooling, carburetor, fuel pump, etc.), application
limitations, ambient operating conditions (temperature, humidity, altitude), and engine-to-engine variability. Due to manufactur
ing and capacity limitations, Briggs & Stratton may substitute an engine of higher rated power for this Series engine.
