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.
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.
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.
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.
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.
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.
SLOPE OPERATION
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 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 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 lose traction.
5. Always keep unit in gear especially when traveling down
slopes. Do not shift to neutral and coast downhill.
6. Avoid starting, stopping, or turning on a slope. If tires
lose traction, disengage the blade(s) and proceed slowly
straight down 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 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.
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 downhill, if possible.

WARNING
If the unit does not pass a safety test, do not operate it.
See an authorized dealer.
Safety Interlock System Tests
This unit is equipped with a Safety Interlock System. Do not
attempt to bypass or tamper with the switches/devices.
Test 1 — Engine should NOT crank if:
• PTO switch is ON, OR
• Brake pedal is NOT fully depressed (parking brake OFF),
OR
• Operator is NOT in seat.
Test 2 — Engine SHOULD crank and start if:
• Operator is sitting in seat, AND.
• PTO switch is OFF, AND
• Brake pedal is fully depressed (parking brake ON).
Test 3 — Engine should SHUT OFF if:
• Operator rises off seat.
Test 4 — Check Mower Blade Stopping Time
Mower blades and mower drive belt should come to a
complete stop within five seconds after electric PTO switch
is turned OFF. If mower drive belt does not stop within five
seconds, see an authorized dealer.
Test 5 — Reverse Mow Option (RMO) Check
• Engine should shut off if reverse travel is attempted if
the PTO has been switched on and RMO has not been
activated.
• RMO light should illuminate when RMO has been
activated.
WARNING
Mowing in reverse can be hazardous to bystanders.
Tragic accidents can occur if the operator is not alert
to the presence of children. Never activate the RMO if
children are present. Children are often attracted to the
unit and the mowing activity.
Check Tire Pressure
Tires should be checked periodically to provide the
optimum traction and to guarantee the best cut (see Figure
7).
NOTE: These pressures may dier slightly from the “Maxi-
mum Ination” stamped on the side walls of the tires.
Oil Recommendations
We recommend the use of Briggs & Stratton Warranty
Certified oils for best performance. Other high-quality
detergent oils are acceptable if classified for service SF,
SG, SH, SJ or higher. Do not use special additives.
Outdoor temperatures determine the proper oil viscosity for
the engine. Use the chart to select the best viscosity for the
outdoor temperature range expected.
* Below 40°F (4°C) the use of SAE 30 will result in hard starting.
** Above 80°F (27°C) the use of 10W-30 may cause increased oil
consumption. Check oil level more frequently.

Check or Add Oil
Before adding or checking the oil
• Place the tractor on a level surface (see Figure 8).
• Clean the oil fill area of any debris.
1. Remove the dipstick (A, Figure 9) and wipe with a clean
cloth.
2. Insert and tighten the dipstick.
3. Remove the dipstick and check the oil level. It should be
at the FULL mark (B) on the dipstick.
4. If low, add oil slowly into the engine oil fill (C). Do not
overfill. After adding oil, wait one minute and then
recheck the oil level.
NOTE: Do not add oil at the quick oil drain (if equipped).
5. Replace and tighten the dipstick.
Oil Pressure
If the oil pressure is too low, a pressure switch (if equipped)
will either stop the engine or activate a warning device on
the equipment. If this occurs, stop the engine and check the
oil level with the dipstick.
If the oil level is below the ADD mark, add oil until it reaches
the FULL mark. Start the engine and check for proper
pressure before continuing to operate.
If the oil level is between the ADD and FULL marks, do not
start the engine. Contact an authorized dealer to have the
oil pressure problem corrected.
Fuel Recommendations
Fuel must meet these requirements:
• Clean, fresh, unleaded gasoline.
• A minimum of 87 octane/87 AKI (91 RON). High altitude
use, see below.
• Gasoline with up to 10% ethanol (gasohol) is acceptable.
NOTICE: Do not use unapproved gasolines, such as E15
and E85. Do not mix oil in gasoline or modify the engine to
run on alternate fuels. Use of unapproved fuels will damage
the engine components and void the engine warranty.
To protect the fuel system from gum formation, mix a fuel
stabilizer into the fuel. See Storage. All fuel is not the
same. If starting or performance problems occur, change
fuel providers or change brands. This engine is certified to
operate on gasoline. The emissions control system for this
engine is EM (Engine Modifications)
High Altitude
At altitudes over 5,000 feet (1524 meters), a minimum 85
octane/85 AKI (89 RON) gasoline is acceptable. To remain
emissions compliant, high altitude adjustment is required.
Operation without this adjustment will cause decreased
performance, increased fuel consumption, and increased
emissions. See an authorized Briggs & Stratton Dealer for
high altitude adjustment information.
Operation of the engine at altitudes below 2,500 feet
(762 meters) with the high altitude adjustment is not
recommended.

deck is not level. See an authorized dealer.
Storage
WARNING
Never store the unit (with fuel) in an enclosed,
unventilated 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.
When Storing Fuel Or Equipment With Fuel in Tank
• Store away from furnaces, stoves, water heaters, or other
appliances that have pilot lights or other ignition sources
because they can ignite fuel vapors.
Equipment
Disengage the PTO, set the parking brake, and remove the
ignition key.
Store battery in a cool, dry place and keep fully charged
during storage. If the battery is left in the unit, disconnect
the negative cable.
Fuel System
Fuel can become stale when stored over 30 days. Stale
fuel causes acid and gum deposits to form in the fuel
system or on essential carburetor parts. To keep fuel
fresh, use Briggs & Stratton® Advanced Formula Fuel
Treatment & Stabilizer, available wherever Briggs &
Stratton genuine service parts are sold.
There is no need to drain gasoline from the engine if a
fuel stabilizer is added according to instructions. Run the
engine for 2 minutes to circulate the stabilizer throughout
the fuel system before storage.
Engine Oil
While the engine is still warm, change the engine oil. See
Changing the Engine Oil section.
Before starting the unit after it has been stored:

Specifications
Power Ratings
The gross power rating for individual gasoline engine models is labeled in accordance with SAE (Society of Automotive
Engineers) code J1940 Small Engine Power & Torque Rating Procedure, and is rated in accordance with SAE J1995.
Torque values are derived at 2600 RPM for those engines with “rpm” called out on the label and 3060 RPM for all others;
horsepower values are derived at 3600 RPM. The gross power curves can be viewed at www.BRIGGSandSTRATTON.
COM. Net power values are taken with exhaust 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 engine-to-engine variability. Given the wide array of products on which engines are
placed, the gasoline 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 not limited 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 manufacturing and capacity limitations, Briggs & Stratton may substitute
an engine of higher rated power for this engine.
