SAFETY INFORMATION
For your safety and the safety of others, pay special attention to these
precautions:
Operator Responsibility
Keep the lawn tractor in good operating condition. Operating a lawn
tractor that is in poor, or questionable condition could result in serious
injury.
Be sure all safety devices are in working order and that warning labels
are in place, these items are installed for your safety.
Know how to stop the engine and blades quickly in case of emergency.
Understand the use of all controls.
Allowing anyone to operate this lawn tractor without proper instruction
may result in injury.
Allowing passengers to ride on the tractor or any of its attachments
may cause the tractor to tip over.
Wear sturdy, full coverage footwear. Operating this tractor with bare
feet, or with open toe shoes or sandals increases your risk of injury.
Dress sensibly. Loose clothing may get caught in moving parts, increasing your risk of injury.
Be alert. Operating this lawn tractor when you are tired, ill or under the
influence of alcohol or drugs may result in serious injury.
Keep all persons and pets away from the mowing area.
Child Safety
Serious injury or death can occur if a child falls off the tractor or runs into
the tractor’s path and is run over by the machine.
l Allowing children to ride as passengers on the lawn tractor can be
dangerous.
l Keep children indoors and supervised at all times when any outdoor
power equipment is being used nearby. Young children move quickly
and are attracted to the tractor and the mowing activity especially if
they have been given rides before.
l Never assume that children will remain where you last saw them.
Be alert, and turn the mower off if children enter the area. Use extreme
care when backing up, and when approaching corners, shrubs, trees,
and other obstructions that might hide children from sight.
l Children should never be allowed to operate the lawn tractor, even
under adult supervision.
5
Cutting Blade Hazard
The cutting blades are sharp, and they turn at high speed. Accidental contact can cause serious injury.
l Keep your hands and feet away from the mower deck while the engine
is running.
l Stop the engine, disengage the Power Take Off (P.T.O.) clutch and
remove the key before inspection or maintenance of the deck or blades.
l Disconnect the spark plug cap to prevent any possibility of accidental
starting. Wear heavy gloves to protect your hands from the blades
when cleaning out the mower deck, or when inspecting or replacing the
blades.
Thrown Object Hazard
Objects hit by the cutting blades can be thrown from the tractor with great
force, and may cause serious injury.
l Before mowing, clear the mowing area of sticks, stones, dog bones,
and other litter and loose objects. Mow only in daylight, or in well-lit
areas at night, so you can see and avoid objects in the grass.
l Before operating the tractor, be sure the side discharge guard is down,
or that the optional grass catcher bags and discharge chute are in place.
l Disengage the Power Take Off (P.T.0.) lever to stop the blades before
crossing a gravel driveway or any other area with loose stones.
l Always inspect the mower for damage after striking a foreign object.
Repair or replace any damaged parts before continued use.
l Broken pieces thrown from a worn or damaged blade can cause serious
injury. Always inspect the blades before using the tractor.
Fire and Burn Hazard
Gasoline is extremely flammable, and gasoline vapor can explode.
Use extreme care when handling gasoline. Keep gasoline out of reach of
children.
l Refuel in a well ventilated area with the engine stopped.
l Allowed the engine to cool before refueling. Fuel vapor or spilled fuel
may ignite.
l Dry grass and leaves may ignite if they are allowed to accumulate
around the engine, the exhaust system, or on top of the cutter deck
(especially around the pulleys).
l It is illegal in some areas to operate an engine without a USDA qualified
spark arrester. Periodic maintenance is required to keep a spark arrester
functioning as designed.
6
The engine and exhaust system become very hot during operation and re-
main hot for a while after stopping. Contact with hot engine components
can cause burn injuries and can ignite some materials.
. Avoid touching a hot engine or exhaust system.
l
Allow the engine to cool before performing maintenance or storing the
lawn tractor indoors.
Carbon Monoxide Poisoning Hazard
Exhaust contains poisonous carbon monoxide, a colorless and odorless
gas. Breathing exhaust can cause loss of consciousness and may lead to
death.
l
If you run the engine in an area that is confined, or even partially enclosed, the air you breathe could contain a dangerous amount of exhaust
gas. To keep exhaust gas from building up, provide adequate ventila-
tion.
Towing Hazard
Towing trailers, garden carts, etc. will affect the stability of the tractor.
Use the proper type of hitch, and never exceed the recommended load
limit and tongue weight. Refer to the recommendations on pages 42 and
43 of this manual.
Operation on Slopes
This lawn tractor is intended for use on relatively flat terrain.
Operating the lawn tractor on slopes exceeding IO degrees (I 7% grade)
could cause the mower to tip over.
NOTE: If you feel that you canndt accurately judge the angle of the grade
to be mowed, we suggest that you obtain an inclinometer.
These slope gauges are available at most hardware stores.
l
When mowing on slopes, empty the grass bags when they are half full.
The weight of full grass bags may cause the lawn tractor to tip over.

trol which could lead to injury. See page 38.
IMPORTANT NoTlCE 1 Improper shift lever operation can damage the
transmission.
Bring the lawn tractor to a complete stop before shifting from a forward
speed to reverse, or from reverse to forward speed. Shifting between forward and reverse speeds while the tractor is moving can cause transmission damage.
When shifting from one forward speed range to another while moving, do
not force the shift lever and do not shift up or down more than one slot at a
time.
NOTE: The lawn tractor will pull away from a stop in any speed range. No
shifting is necessary.
Be sure that the shift lever is in the MOWING range whenever mowing.
Mowing in the 5th or 4th speed range is not recommended; as this will af-
fect cut quality. 5th and 4th speed range should only be used to drive to
and from the mowing area.
NOTE: An interlock switch prevents the engine from starting unless the
shift lever is in the N (neutral) position.

ENGINE OIL
IMPORTANT NOTICE
1 Running the engine with low oil level will cause
serious engine damage.
1. Place the lawn tractor on a level surface.
2. Open the engine hood, wipe dust and dirt from around the oil filler cap,
remove the cap and wipe the dipstick clean.
3. Insert the dipstick into the oil filler neck, but do not screw it in.
4. If the level is low, add the recommended oil to the upper mark on the
dipstick. Do not overfill.
Use high-detergent, premium quality 4-stroke engine oil, certified to meet
or exceed U.S. automobile manufacturer’s requirements for API Service
Classification SG, SF/CC, CD.
IMPORTANT NoTlCE Using nondetergent oil or 2-stroke engine oil could
shorten the engine’s service life.
SAE low-30 is recommended for general, all-temperature use. Other
viscosities shown in the following chart may be used when the average

GASOLINE
Remove the gas cap and check the fuel level. Refill the tank if the level is
low.
If the low fuel indicator lamp glows, it means you have about 1 .O P (0.26
US gal) or less remaining and should refuel.
Gas
tank capacity: 9.0 P (2.38 US gal, 1.98 lmp gal)
Gasoline is extremely flammable, and gasoline vapor can explode. Use ex-
treme care when handling gasoline. Keep gasoline out of reach of children.
l Refuel in a well ventilated area with the engine stopped. Keep flames
and sparks away, and do not smoke in the area.
l Gasoline vapors or spilled gasoline may ignite.
l Refuel carefully to avoid spilling gasoline. Avoid overfilling the fuel tank
(there should be no gas in the filler neck). After refueling, tighten the
gas cap securely. If any gasoline was spilled, make sure the area is dry
before starting the engine.
l After use, park the lawn tractor on a level surface. Be sure the storage
area is well ventilated, do not allow flames or sparks in the storage area.
After refueling, be sure to tighten the gas cap firmly.
UPPER LEVEL
Gasoline Recommendation
Pump octane rating: 86 or higher
We recommend unleaded gasoline because it produces fewer engine and
spark plug deposits and extends the exhaust system life.
If “spark knock” (metallic rapping noise) or persistent “pinging” occurs at
a steady engine speed under normal load, change brands of gasoline. If
spark knock or pinging persists, see an authorized Honda lawn tractor
dealer.
1 IMPORTANT NOTICE 1
pinging can cause engine damage.
Running the engine with persistent spark knock or pinging is considered
misuse, and the Distributor’s Limited Warranty does not cover parts
damaged by misuse.
Occasionally you may hear light spark knock while operating under heavy
loads. This is no cause for concern. It simply means your engine is
operating efficiently.
Never use stale or contaminated gasoline or an oil/gasoline mixture. Avoid
getting dirt or water in the gas tank.
R
unning the engine with persistent spark knock or
18
GASOLINES CONTAINING ALCOHOL
If you decide to use a gasoline containing alcohol (gasohol), be sure its octane rating is at least as high as that recommended by Honda (see
Gasoline Recommendation on page 18). There are two types of
“gasohol”:
one containing ethanol, and the other containing methanol.
1 IMPORTANT NOTICE 1
u
sing gasohol that contains more than 10% ethanol,
- -
or gasoline containing methanol (methyl or wood alcohol) that does not
also contain cosolvents and corrosion inhibitors for methanol, can cause
serious fuel system damage and poor engine performance.
Never use gasoline containing more than 5% methanol, even if it has
cosolvents and corrosion inhibitors.
Honda cannot endorse the use of gasoline containing methanol since
evidence of its suitability is as yet incomplete.
NOTE: Fuel system damage or engine performance problems resulting
from the use of gasoline that contains alcohol is not covered under the
warranty.
Before buying gasoline from an unfamiliar station, first determine if the
gasoline contains alcohol; if it does, find out the type and percentage of
alcohol used.
NOTE: If you notice any undesirable operating symptoms while using a
gasoline that contains alcohol, or one that you think contains alcohol,
switch to a gasoline that you know does not contain alcohol.
19
Air cleaner
Check that the air cleaner elements are clean and in good condition. A dir-
ty air cleaner will restrict air flow to the carburetor, reducing engine perfor-
mance. A damaged air cleaner will allow dirt to enter the engine, causing rapid engine wear.
1. Open the engine hood, and remove the wing nut to remove the air
cleaner cover and air cleaner elements.
2. Inspect the air cleaner elements.
Clean or replace the elements if
necessary. If the air cleaner elements need cleaning, follow the procedure described on page 47.
3. Reinstall the air cleaner elements and air cleaner cover. Tighten the
wing nut.
