MOWER SAFETY

IMPORTANT SAFETY INFORM;ATION
Most accidents with riding mowers can be prevented if you
follow all instructions in this manual and on the riding
mower. The most common hazards, according to accident
statistics, are discussed below, along with the best way to
protect yourself and others.

Avoid Rotating Blades
A rotating blade can cause serious cuts and even amputate
fingers, hands, toes, or feet. Keep away from the mower
deck whenever the engine is running. If you need to work
around the deck to clear a grass accumulation or for any
other reason, always shut off the engine and remove the
key. Disconnect the spark plug cap, and wear heavy gloves
when you need to clean the mower deck or handle a blade.

Clear

Mowing

Area

A riding mower blade can throw rocks and other objects
with enough force to cause serious injury. Before mowing,
carefully inspect the area and remove all sticks, stones,
pieces of wire, and other loose objects. Never operate the
mower over gravel or any other loose objects.

Keep Shields in Place
Guards and shields are designed to protect you from being
hit by thrown objects and to keep you from touching hot
engine parts and moving components. For your safety and
the safety of others, keep all shields in place when the
engine is running.

MOWER SAFETY

Refuel with Care
Gasoline is extremely flammable, and gasoline vapor can
explode. Allow the engine to cool if the riding mower has
been in operation. Refuel only outdoors in a well-ventilated
area with the engine OFF. Never fill the fuel tank beyond the
maximum fill mark. Never smoke near gasoline, and keep
other flames and sparks away. Always store gasoline in an
approved container.

Wear Protective Clothing
Wearing protective clothing will reduce your risk of injury.
Long pants and eye protection reduce the risk of injuries
from thrown objects. Sturdy shoes with aggressive soles
provide

better traction

on the riding

mower’s

platform

and

pedals.

Turn Engine Off When Not Mowing
If you need to leave the mower for any reason, even just to
inspect the lawn ahead, always turn the engine off. And take
the key if you go farther away.

Operation on Slopes
This riding mower is intended for use on relatively flat
terrain. Operating the riding mower on slopes exceeding 10
degrees (17% grade) could cause the mower to tip over.
Always mow up and down slopes, never across. When
mowing up and down slopes, empty the optional grass bags
when they are half full. Never use the optional grass bags
without the front weight installed.

Mowing Conditions
Mow only in daylight or good artificial light. Do not drive the
riding mower at night or under poor light conditions.

Mowing Near Roads
Always watch for vehicle traffic when operating the riding
mower near roads and driveways. Never drive the riding
mower on public roads.

MOWER SAFETY

SAFETY LABEL LOCATIONS
These labels warn you of potential qazards that can cause
serious injury. Read them carefully. If a label comes off or
becomes hard to read, contact your Honda riding mower
dealer for a replacement.

MOWER SAFETY

CHILD SAFETY: A MESSAGE =ro PARENTS
YOUR CHILD’S SAFETY IS VERY IMPORTANT to Honda.
Read this message if you decide to permit your youngster to
operate this riding lawn mower. Riding lawn mowers are
tools, not toys. As with any equipment, bad judgments can
result in serious injuries. You can help prevent accidents by
making good decisions about if, when, and how your
youngster operates this equipment.
The first question you’ll need to ask. is whether your
youngster is capable of operating this riding mower safely.
Remember, young people vary widely, and AGE IS NOT
THE ONLY FACTOR. Physically, a youngster must be
LARGE ENOUGH AND STRONG EiNOUGH to easily start
the riding mower and control its direction. The youngster
also needs enough size, strength, and coordination to
comfortably reach and operate the controls.
Another, tougher question you need to ask is if your
youngster has enough MATURITY AND RESPONSIBILITY
to safely operate this riding mower. Does the young person
think through problems and come to logical solutions? Be
honest! Anyone who takes unnecessary risks and doesn’t
obey rules should not operate this riding lawn mower.
If you decide that your son or daugh:er can handle the riding
mower safely, CAREFULLY READ THE OWNER’S MANUAL
with your youngster. Make sure you both understand all
instructions and safety information. Also, be sure your
youngster wears sturdy shoes and other protective clothing
when operating or handling the riding mower.
SUPERVISION is important. Walk behind your youngster
during the first few minutes of mowing. Even after the
youngster is confident, do not let them use the mower
without supervision. An adult should also be present during
refueling and maintenance. Be sure the riding mower is
properly maintained and kept in sa’!e operating condition.
By always placing safety first, your youngster will acquire
useful skills and a sense of accomplishment. And you’ll both
get the best results from your riding lawn mower.

CONTROLS

DESCRIPTION OF CONTROLS
You will use these controls every tirne you operate the
riding mower. The Hl 011 riding mower uses colors to
identify control types. Orange levers and knobs are used to
control the movement of the riding mower. For example, the
parking brake lever and shift lever are color coded orange.
Yellow controls identify attachment controls, such as the
hand grip on the PTO clutch lever that is used to start and
stop blade movement. Black is used for component lift
controls (for example, deck height adjustment).

Seat
The seat can be adjusted back and forth for operator
comfort and tilted forward for battery access on electric start
models. Refer to page 53 for instructions.

Fuel Valve
The fuel valve is located on
the carburetor, above the
right rear tire. Look
underneath the rear cover
to find the fuel valve. The
fuel valve must be ON to
start the engine and should
be OFF when the riding
mower is not in use.

Ignition Switch
The ignition switch is used
to start (electric start
models) and stop the
engine.
On the recoil start model,
this switch must be ON
before starting.
The key can only be
inserted and removed
when
14

the switch

is OFF.

CONTROLS

Height Adjustment Lever
This lever is used to raise
and lower the mower deck.
When the mower deck is
properly leveled, the
numbers near the height
adjustment lever indicate
the approximate number of
inches the forward blade tip
is from the ground.

Clutch Pedal (gear transmission models)
The clutch pedal is used when shifting between gears and
when stopping and starting the riding mower. Pressing the
clutch pedal all the way down disengages the engine from
the transmission and allows you to move the shift lever
smoothly between gears.

Brake Pedal (gear transmission models)
The brake pedal applies a brake to the rear wheels. The brake
pedal should only be used once the clutch pedal is pressed all
the way down, except when starting on a sloped surface.
lNoTlCEl
Partially pressing the brake pedal without first pressing the
clutch pedal all the way down can cause the drive belt to
wear prematurely.

Brake Pedal (hydrostatic transmission model)
The brake pedal is linked to both the shift lever and the rear
wheel brake. When the brake pedal is fully pressed, the shift
lever returns to NEUTRAL and a brake is applied to the rear
wheels.
When the shift lever is not in NEUTRAL and the brake pedal
is partially pressed, the shift lever moves toward NEUTRAL.

CONTROLS

Shift Lever (gear transmission miDdels)
This lever is used to select
one of the five forward
speeds, NEUTRAL, or
REVERSE. lst, 2nd and
3rd gears are recommended for varying
mowing conditions. 4th and
5th gears are used when
not mowing and greater
ground speed is desired
Cut quality will suffer if you attempt to mow using 4th or 5th
gear.
Moving the shift lever to NEUTRAL permits you to release
the clutch pedal when the riding mower is stopped and the
engine is running.
REVERSE is used to back up the riding mower.
You can damage the transmission of the riding mower if you
move the shift lever between REVERSE and any forward
gear without coming to a full stop. F’ress on the brake pedal
(if needed) to bring the riding mower to a full stop before
moving the shift lever.

Shift Lever (hydrostatic transmission

model)

This lever is used to select
the travel (ground) speed
of the riding mower.
Moving the shift lever out
of NEUTRAL wil! cause the
riding mower to move.
Small movements of the
shift lever will in turn cause
small changes in travel
speed.
The MOWING range is for mowing, REVERSE is used to
backup and TRANSPORT offers faster travel speeds when
driving the riding mower to and from the mowing area. Cut
quality will suffer if you attempt to mow in the TRANSPORT
range.

CONTROLS

Throttle
The throttle lever controls
engine speed. Push the
throttle down to the SLOW
position for idle. Pull it up to
the FAST position for
mowing. Pulling the throttle
upward past the detent near
FAST to the CHOKE position
applies the choke for starting
a cold engine.

PTO Clutch Lever
PTO stands for Power Takeoffand refers to the part of your
riding mower where engine power is applied to the mower
deck.
The forward position is ON;
this starts the mower blade
spinning. The rear position is
OFF, and this stops the
mower blade from spinning.
When the PTO is moved to
ON, you’ll notice a temporary
drop in engine speed.
The PTO clutch lever should
always be engaged with a
smooth and quick motion.
You should always
disengage the PTO when not
actually mowing.

PTOON

PTO OFF

The riding mower will not
start if the PTO is ON. The
engine will stop if you rise off
the seat when the PTO lever
is ON.

CONTROLS

Parking Brake Lever
This lever is used to prevent movement of the riding mower
when it is parked. You should always set the parking brake
lever ON before getting off the riding mower. Release the
parking brake lever before moving the shift lever into any gear.
The parking brake is set by
pressing and holding the brake
and clutch pedals (gear
transmission models) or just
the brake pedal (hydrostatic
transmission model) all the way
down, then moving the parking
brake lever down. The
pedal(s), remain locked down
by the parking brake lever.
To release the parking brake, press down and hold the brake
and clutch pedals (gear transmission models) or just the brake
pedal (hydrostatic transmission model), then move the parking
brake lever up. You can then gently release the pedal(s). The
engine will stop if you rise off the seal without the parking
brake engaged. You should always move the shift lever to
NEUTRAL before setting the parking brake.

Transmission Release Lever
(hydrostatic transmission model)
This lever is used to
engage or disengage the
hydrostatic transmission.
When operating the riding
mower under its own
power, leave the lever in
the ENGAGED position.
Should you need to push
the riding mower, move
the lever to DISENGAGED.

BEFORE MOWING

CHECK YOUR LAWN
For your safety and the safety of others, always inspect the
area before mowing.
Objects
Anything which can be picked up by the blade and thrown is
a potential hazard to you and others. Look for things like
stones, sticks, bones, and wire, and remove them from the
mowing area.
People and Pets
People and animals near the mowing area can move into
your mowing path or into a position where they could be
struck by thrown objects. Clear the area of people,
especially children and pets. Their safety is your
responsibility.
Lawn
.Check the length and condition of the grass. Adjust your
mowing speed and cutting height accordingly.
Avoid mowing wet grass. Not only does mowing wet grass
result in poor cut quality, it also affords poor traction,
increasing the risk of loss of control of your riding mower.

BEFORE MOWING

CHECK YOUR RIDING LAWN MOWER
For your safety and the service life of your equipment,
always inspect your riding mower before using it. Before
beginning your pre-operation checks, be sure:
l

The riding mower is parked on a level surface.
The PTO clutch lever is OFF and the shift lever is in
NEUTRAL.

The ignition switch is OFF and the key is removed.

The parking brake is ON.

General Items
Walk around the riding mower and check its general
condition. Look around and underneath it for signs of fluid
leaks.
Remove any excessive dirt and debris, especially around
the engine, mower deck, and moving components. Look for
signs of damage. Check nuts, bolts, screws, and pins for
tightness.
Keep all shields and covers in place while operating the
riding mower. If you find any problems, have them repaired
before mowing.

THE MOWER

MOWING PRECAUTIONS
Before operating the riding mower for the first time, please
review the IMPORTANT SAFETY INFORMATION
beginning on page 6 and the previous section, titled
BEFORE MOWING.
Even if you have operated other riding mowers, take time to
become familiar with how this riding mower works, and
practice in a safe area until you build up your skills.
Never tamper with, or alter any of the controls or safety
devices on the riding mower.
For your safety, avoid operating the engine in an enclosed
area such as a garage. Your riding mower’s exhaust
contains poisonous carbon monoxide gas which can collect
rapidly in an enclosed area and cause illness or death.
The Honda Hl 011 riding mower is easy to operate and
highly maneuverable. You need a complete understanding
of its operation and a certain amount of practice with its
controls to safely realize the full potential of this riding
mower.
Read this section completely before operating the riding
mower. Take time to familiarize yourself with the controls
and how they operate.
The small amount of time spent in familiarization
you with greater efficiency and reduced risk.

will reward

OPERATING

THE MOWER

Starting the Engine
Start the engine outside in an
open area with good
ventilation.

Locate the fuel valve on the
carburetor, just above the
right rear tire. Move the fuel
valve to the ON position.
Pushing the fuel valve handle
toward the engine to ON
allows fuel to flow.

Make sure the PTO lever is
OFF (disengaged), the
parking brake is set ON, and
the shift lever is in NEUTRAL.

I\ON

The engine will not start
unless these controls are
properly set.

To start a cold engine, move
the throttle lever to FAST,
then press the lever
outward, slightly past a
detent to CHOKE. To
restart a warm engine,
move the throttle lever to
the FAST position.

OPERATING
4.

THE MOWER

(electric start) Insert the
ignition key into the
ignition switch. Turn the
key clockwise to START
and hold it there briefly
until the engine starts.
When it does, let the key
return to the ON position.

4a. (recoilstart) Insert the key
into the ignition switch and
turn it to ON. Grasp the
handle on the pull rope
and slowly pull until
resistance is felt, then pull
it briskly. Do not allow the
rope to snap back toward
the engine.

INOTICEI
(electric start models) Holding the ignition key in the START
position for more than five seconds may damage the starter.
5.

If the engine fails to stat-t, wait at least ten seconds before
trying again. If you can’t get the engine to start after multiple
tries, refer to “Troubleshooting”
on page 103.

After the engine has started,
slowly move the throttle
lever from CHOKE to a
point halfway between
SLOW and FAST while
the engine warms up.

Once the engine has warn led,
you should keep the
throttle in the FAST
position while mowing.
This keeps the mower
blade spinning at the
proper speed (when the
PTO is ON) and provides
the best cut quality.

OPERATING

THE MOWER

Do not use the throttle to adjust the riding mower ground
speed. Use the shift lever to select a different speed
instead. Slowing the riding mower’s ground speed with the
throttle causes the blade to spin slower, and cut quality will
suffer.

Driving the Riding Mower
Once the riding mower is moving forward, you’ll need to
know how to steer correctly, shift gears to adjust speed,
begin mowing, and how to stop.

Steering
To make it easier to cut various lawns, the HlOl 1 riding
mower is very maneuverable and can turn quickly.

Turning sharply when using higher
ground speeds can cause the riding
mower to lose traction.
The riding mower can tip over and you
can be injured or killed.
Avoid sharp turns when using higher
gears.
After using the riding mower for a while, you’ll get a better
feel for how much effort to use on the steering wheel for a
particular turn.
The speed of the riding mower greatly affects how the
steering responds. For this reason, you should shift the
transmission to a lower ground speed before entering sharp
turns.
Avoid turning the riding mower when operating on a sloped
surface. See “Mowing on Slopes” (page 38) for more details.

Selecting the Right Speed
Your Honda riding mower is equipped with a transmission
that offers multiple ground speeds. The shift lever is used to
select the appropriate ground speed for the task at hand.

OPERATING

THE MOWER

For the best cut quality, the engine should always be
operated with the throttle set in the FAST position. When
you need to speed up or slow down the riding mower, use
the shift lever (not the throttle) to change the ground speed.
.
Gear Transmission MQ&& : 1st - 3rd gears work best for
most mowing jobs. 4th and 5th gears should be used only
for transporting the mower (when the PTO is OFF) and are
not recommended for mowing.
Hydrostatic Transmission Model: Keep the shift lever in the
MOWING range. The TRANSPORT range should only be
used for transporting the mower (when the PTO is OFF)
and is not recommended for mowing.
On slopes or hills, use a slower shi,ft lever setting to
maintain a controllable, steady speed. Also, use slower
ground speeds under the following conditions:

REVERSE is used to back up the riding mower. Before
traveling in REVERSE, make sure the PTO is off and the
path is clear of people, pets and obstructions.

Mowing
When ready to begin mowing, approach the mowing area at
a reduced ground speed. Bring the riding mower to a full
stop, and check the position of the height adjustment lever.
You may have to make some trial cuts to determine which
setting is best for the lawn.
To begin mowing, make sure the throttle is set to FAST,
then move the PTO clutch lever to ON with a smooth, quick
motion. When you do, the blade starts to turn. To stop the
blade from turning, move the PTO to OFF.
piq
Do not operate the PTO clutch lever in an attempt to clear a
clogged mower deck. Doing so can damage the mower belt.

OPERATING

THE MOWER

See the “Mowing Tips” section later in this chapter for
details on getting the best cut possible from the riding
mower.

Braking (gear transmission models)
For best control, avoid stopping the riding mower on sloped
surfaces.
1.

When approaching the area where you wish to stop,
smoothly press the clutch pedal all the way down and hold it
there. If necessary, press the brake pedal down, but only do
this when the clutch pedal is pressed first.

Once the riding mower has fully stopped, hold the clutch
and brake pedals down and move the shift lever to
NEUTRAL.

If this is an extended stop, set the parking brake ON, then
release the pedals.
p?iq
Partially pressing the brake pedal without first pressing the
clutch pedal can cause the drive belt to wear prematurely.
When using the brake pedal, press the brake pedal all the
way down and only when the clutch pedal is pressed first.

Braking (hydrostatic transmission model)
For best control, avoid stopping the riding mower on sloped
surfaces. The hydrostatic transmission on the HlOl 1 H
allows you two options for braking. You can either move the
shift lever or the brake pedal to slow down or stop the riding
mower.
Using the shift lever: To reduce the ground speed of the
riding mower, move the shift lever toward NEUTRAL.
Moving the shift lever fully into NEUTRAL will bring the
riding mower to a full stop as long as the ground is level. If
the riding mower is on a slope, you must press and hold the
brake pedal to completely stop the riding mower.

OPERATING

THE MOWER

Using the brake pedal: Partially pressing the brake pedal
causes the shift lever to move toward NEUTRAL. This
action causes the hydrostatic transmission to act as a
hydraulic brake and the riding mower slows down. Pressing
the brake pedal all the way down moves the shift lever fully
into the NEUTRAL position and applies a mechanical brake
to the rear wheels.

Adjusting Speeds (gear transmission models)
Always use the clutch pedal before moving the shift lever
between any forward gears. If shifting between any forward
gear and REVERSE, use the clutch and brake pedals to
bring the riding mower to a full and complete stop.

Operating the shift lever on ;a sloped
surface can cause the riding mower to
lose traction.
The riding mower can tip over and you
can be killed or seriously injured.
Do not operate the shift lever while the
riding mower is on a sloped surface.
When shifting between forward speleds, always use the
clutch pedal and move to the next higher or lower gear. You
can start off from a complete stop when any gear is
selected.

Safe Mowing Practices
For your safety, keep all four wheels on the ground, and
avoid losing control of the riding mower.
Keep a firm grip on the steering wheel. Be very careful when
mowing uneven or rough ground.
Do not operate the riding mower near embankments, drop
offs or ditches. The riding mower could suddenly turn over if
a wheel is near the edge and it caves in or gives way.
Do not attempt to stabilize the riding mower by putting your
foot on the ground. Keep your feet on the platform and near
the pedals.
Take extra care when mowing near blind corners, shrubs,
trees or any other objects that may obscure your vision. If
you do strike an object, set the parking break, remove the
ignition key and inspect the riding mower for damage.
Repair any damage before any further operation.

The blades are sharp and spin at high
speed.
A spinning blade can cut you severely
and can amputate fingers and toes.
l
l

Wear protective footwear.
Keep your hands and feet away
from the mower deck while the
engine is running.

Stop the engine before performing any
adjustment, inspection, or maintenance.

OPERATING

THE MOWER

Mowing on Slopes
Never mow on a sloped surface greater than 10 degrees
(17% grade), since this can cause the riding mower to tip
over. Use a lower gear for better control and avoid sudden
stops or starts when on a sloped surface. If you are unsure
of the grade, obtain an inclinometer from a hardware store
to measure the area in question.

10 DEGREES
(17 % GRADE)
MAXIMUM

Always mow up and down a sloped surface, never across.
When mowing on slopes, empty the optional grass bags
when they are half full. Never operate the shift lever when
mowing on a sloped surface. Never mow a sloped surface
when the grass is wet. Avoid stopping on a sloped surface.
If it becomes necessary to stop on a sloped surface, use the
following special procedure when restarting the riding
mower.
Starting on a Sloped Surface

Obstacles
Use the side of the mower deck to cut close to large
obstacles, such as fences or walls.
Be careful when mowing over obstacles embedded in the
lawn, such as sprinkler heads, paving, edging, etc. Avoid
anything that sticks up above the surface of the lawn.
If a blade hits something, or if any part of the riding mower
starts to vibrate, stop the engine immediately and check for
damage. Striking objects may damage a belt, blade, and/or
break the mower deck or other components. Vibration
usually indicates serious trouble.

A worn, cracked or damaged blade can
break, and pieces of the damaged
blade can become projectiles.

Thrown obiects can cause serious
injury.
-

Inspect the blade regularly, and do not
operate the riding mower with a worn
1 or damaged blade.
The distributors limited warranty does not cover parts
damaged by accident or collision.

OPERATING

THE MOWER

Gravel and Loose Objects
Gravel, loose stones, and landscaping material can be
picked up by the riding mower and thrown many feet with
enough force to cause serious personal injury and/or
property damage. The best way to prevent potential injury
from thrown objects is to move the PTO lever to OFF prior
to reaching areas with gravel, loose stones, or landscaping
material.

Mowing Tips
In this section, you’ll learn some tips to getting a high quality
cut with your Honda riding mower.

General Tips
The mower blade must spin very fast for a good quality cut.
Keep the throttle in the FAST position when mowing. In
general, a slower ground speed produces a better quality
cut.
Try to maintain a constant travel speed when possible.
Changing speeds can produce an uneven finish.

Grass Condition
Mow when the grass is dry. Mowing wet grass does not
produce a neat finish. The inside of the mowing deck or
bagging chute may clog when mowing wet grass. Clumps of
wet grass will collect on the lawn and can create harmful
thatch.
A wet lawn reduces traction and braking performance of
your riding mower. Further, the tires may leave marks on
wet soil softened by moisture. This can detract from the
overall appearance.

How Often?
A well-groomed lawn requires mowing at short, regular
intervals. During the growing season, a lawn may require
mowing twice a week.

The mowing deck can be positioned in a range of equally
spaced heights: 1.0, 1.5, 2.0, 2.5, 3.0 and 3.5. These
numbers indicate the approximate cutting height in inches.
To prevent possible damage to the mower deck, always
raise it fully (3.5) when driving the riding mower to and from
the mowing area; this provides maximum ground clearance.
To avoid damaging or disabling the mower deck height
adjustment lever, never attempt to move the lever when the
riding mower is moving.
A higher cut may be needed to protect the lawn during the
hotter summer months. Consult a local nursery or lawn and
garden center for advice about specific types of grasses and
growing conditions in your area.
Most grasses should be cut when they have grown l/2 to 1
inch above the recommended height. If your grass grows
too tall, cut it back a little at a time, allowing a few days for
the grass to recover between mowings. Avoid cutting more
than one third of the total grass height in any one mowing.

OPERATING

THE MOWER

Mowing Patterns
The mowing pattern you use on the lawn can greatly affect
the overall quality of the finished cut.
Side-Discharge

Mowing

Start mowing from the outside edge of the mowing area and
work toward the center. Avoid mowing patterns that cause
clippings to be discharged onto uncut grass and cause
clumping. Typically, a counterclockwise
pattern is a good
choice and provides a smooth, even finish. However, you
may wish to alter the pattern to prevent clippings from
accumulating in areas such as a nearby patio or driveway.

Overlapping

Your Path

Allow an adequate amount
of overlap in the cutting
path when mowing. Four to
six inches is
recommended; this is
roughly the same width as
a front tire.

When overlapping in a
curve, shift to a lower
speed and overlap the
previous cut by 50%, or
approximately half the
width of the mower deck. In
extremely tall or thick
grass, you may have to cut
a larger overlap.

After Mowing
Always take a few moments to inspect the riding mower
when you’ve finished mowing. A few simple steps done now
can greatly prolong the life of your riding mower and make it
easier to use the next time.
Under most conditions, the riding mower accumulates
clippings, mud, dirt and other debris on the mower deck and
other areas. Frequently, such debris contains moisture and
if allowed to remain on the mower frame, mower deck or
other metal parts, rust can form. Regular cleaning not only
helps prevent such rusting, but also makes the riding mower
operate better. Also, it is much easier to clean these parts
when the debris or clippings are fresh rather than stuck on
the riding mower for days or weeks at a time.

OPERATING

THE MOWER

Mower Deck Cleaning
After each use, allow the engine and exhaust areas to cool.
Inspect, then clear and clean the mower deck of debris. A
good spraying of water can clear most clippings, dirt and
mud.
Wash the mower deck only when the riding mower is cool.
The bearings on the blade pulley shaft expand as they heat
up. Cooling rapidly with water can allow moisture to be
trapped inside the bearings. This can cause rust to form on
the bearing surfaces and shorten bearing life.
Clean both the top and bottom of the mower deck and also
the area around the discharge chute. Operate the engine
and mower for a few minutes after washing to dry moving
parts.
Cleaning

Other Areas

Certain

parts other than the mower

deck can accumulate

clippings and other debris. When the riding’mower is cool,
you should inspect these areas and brush or wipe off any
debris with a soft brush or slightly damp rag. Specifically,
remove the rear cover and look around the top of the
engine, exhaust area and muffler and by the rear axle near
the frame. Do not spray water directly on the engine.
Check and clean (if needed) the footwells, lower and upper
chutes (when the optional grass balg kit is used), engine
cooling fan screen and air intake path behind the seat.

High Altitude Operation
At high altitude, the standard carburetor air-fuel mixture will
be too rich. Performance will decrease, and fuel
consumption will increase. A very rich mixture will also foul
the spark plug and cause hard starting.
High altitude performance can be improved by installing a
smaller diameter main fuel jet in the carburetor. If you
always operate the mower at altitudes higher than 1,800
meters (6,000 feet) above sea level, have an authorized
Honda riding mower dealer perform this carburetor
modification.

OPERATING

THE MOWER

Even with carburetor modification, engine horsepower will
decrease about 3.5% for each 300 meter (1,000 foot )
increase in altitude. The effect of altitude on horsepower will
be greater than this if no carburetor modification is made. A
reduction in engine horsepower will reduce mowing
performance.
When the carburetor is modified for high altitude operation,
the air-fuel mixture will be too lean for low altitude use.
INOTICEI
Operation at altitudes below 1,800 meters (6,000 feet), with
high altitude carburetor modifications, may cause the engine
to overheat and result in serious engine damage.
For low altitude use, reinstall the standard main fuel jet.

THE IMPORTANCE OF MAINTENANCE
Good maintenance is essential for safe, economical, and
trouble free operation. It will also help reduce air pollution.

Improper maintenance, or failure to correct a problem before operation, can
cause a malfunction in which you can
be seriously hurt or killed.
Always follow the inspection and maintenance recommendations and schedules in this owner’s manual.
To help you properly care for your riding mower, the
following pages include a maintenance schedule, routine
inspection procedures, and simple maintenance procedures
using basic hand tools. Other service tasks that are more
difficult, or require special tools, are best handled by
professionals and are normally performed by a Honda
technician or other qualified mechanic.
The maintenance schedule applies to normal operating
conditions. If you operate your riding mower under unusual
conditions, consult you servicing dealer for
recommendations
applicable to your individual needs and
use.
Remember that your servicing dealer knows your riding
mower best and is fully equipped to maintain and repair it.

For certain operations, the riding mower must be raised off the
ground. Be sure the riding mower is solidly supported before
you put any part of your body under the riding mower.

MAINTENANCE
l

& ADJUSTMENTS

Disconnect the spark plug cap and wear heavy gloves
when working near the mower deck, belts, or blades.
Never support or stand the riding mower on either side
or end. Fuel, oil, or battery electrolyte can leak out.

EMISSION CONTROL SYSTIEMI
Source of Emissions
The combustion process produces carbon monoxide, oxides
of nitrogen, and hydrocarbons. Control of hydrocarbons and
oxides of nitrogen is very important because, under certain
conditions, they react to form photochemical smog when
subjected to sunlight. Carbon monoxide does not react the
same way, but it is toxic.
Honda utilizes lean carburetor settings and other systems to
reduce the emissions of carbon monoxide, oxides of nitrogen,
and hydrocarbons.

The U.S. and California Clean Air Acts
EPA and California regulations require all manufacturers
furnish written instruction describing the operation and
maintenance of emission control systems.

The following instructions and procedures must be followed to
keep the Honda engine emissions within the emission
standards.

Tampering and Altering
Tampering with or altering the emission control system may
increase emissions beyond the legal limit. Among those acts
that constitute tampering are:

Replacement Parts
The emission control systems on your new Honda engine were
designed,

built, and certified

to conform

with EPA and California

emission regulations. We recommend the use of genuine Honda
parts whenever you have maintenance done. These
original-design replacement parts are manufactured to the same
standards as the original parts, so you can be confident of their
performance. The use of replacement parts that are not of the
original design and quality may impair the effectiveness of your
emission control system.
A manufacturer of an aftermarket part assumes the responsibility
that the part will not adversely affect emission performance. The
manufacturer or rebuilder of the part must certify that the use of
the part will not result in a failure of the engine to comply with
emission regulations.

Maintenance
Follow the Maintenance Schedule on page 52. Remember that
this schedule is based on the assumption that your machine will
be used for its designed purpose. Sustained high-load or
high-temperature

To access the battery compartment or to adjust the seat
position, you must raise and lock the seat.
Raising and Locking the Seat
1.

On the left side of the riding mower, just below the seat
cushion, there is a spring loaded, U-shaped pin used to lock
the seat in either a raised or lowered position. Pull the pin
outward and away from the seat, then raise the seat up.

With the seat in the fully
raised position, allow the
pin to slide back toward the
seat bracket to lock it in the
up position.

Verify the seat is locked in
the upright position by
pressing down on the seat.

Adjusting

the Seat Position

Locate and loosen (don’t
remove) the four hex bolts
used to attach the seat to
the seat bracket.

Move the seat back and forth to obtain the desired position.

Securely tighten the four hex bolts, then lower and lock the
seat.

Lowering and Locking the Seat
1.

To lower the seat, slightly move the seat upward, to take
pressure off the locking pin.

While grasping the seat with one hand, use your other hand
to pull the locking pin away from the seat bracket.

Lower the seat all the way down, then release the locking
pin, so it locks into the hole on the side of the seat bracket.
Verify that the seat is locked down by trying to lift the seat.

& ADJUSTMENTS

Rear Cover
The rear cover must be removed to perform some
maintenance procedures. It must also be removed prior to
transporting the riding mower.
To Remove the Rear Cover
1.

Stand behind the riding
mower and grasp the
edge underneath the rear
cover.

Pull upward, then lift the rear
cover away from the riding
mower.

To Reattach the Rear Cover
1.

There are square tabs molded into the front edge of the rear
cover, near the air intake area. Insert these tabs into the
riding mower rear body, just behind the seat.

Lower the rear cover so the rounded edge aligns with the
clips in the rear body.

The two posts on the lower edges of the rear cover should
be carefully pressed into the rubber grommets on the rear
body.

Air Clearier
Check that the air cleaner elements are clean and in good
condition. A dirty air cleaner assembly restricts air flow to
the engine, reducing performance. A damaged element
allows dirt to enter the engine, causing rapid engine wear.
1.

Remove the rear cover. As you face the rear part of the
exposed engine, the air cleaner is located on the right rear
side of the engine. Remove the wing nut from the top of the

the engine has been running, allow it to cool. Avoid
overfilling the tank or spilling fuel.

MAINTENANCE

& ADJUSTMENTS

Spilled fuel not only creates a fire hazard, it can cause
environmental damage. Wipe up spills immediately. Dispose
of gasoline properly.

Fuel Recommendation
Honda recommends unleaded fuel (86 pump octane)
because it produces fewer engine and spark plug deposits
and extends exhaust system life.
Be sure the gasoline you use is as fresh as possible. Stale
or contaminated gasoline or an oil/gasoline mixture can
damage the engine or its fuel system. Avojd getting dirt or
water in the fuel tank.
When the engine speed drops under heavy loads, you may
hear light “spark knock” or “pinging” (a metallic rapping
noise). This is no cause for concern.
However, if this spark knock or pinging occurs at a steady
engine speed, under a normal load, the engine can be
damaged. Try using fresh gasoline in the tank or change
brands of gasoline. If spark knock or pinging persists,
contact your authorized Honda riding mower dealer.
Running the engine with persistent spark knock or pinging
can cause engine damage. This type of damage is not

Battery Service (electric start models)
The riding mower charging system charges the battery while
the engine is running. However, if the riding mower is only
used periodically, the battery must be charged monthly to
maintain the battery service life.
A lead-acid battery self-discharges at a rate of 0.5 - 1 .O %
per day. If the riding mower is not operated for a month, the
battery can discharge as much as 30%. This could cause
the engine not to start or shorten the service life of the
battery. To charge the battery, follow the procedures below.
Removal
1.

Raise and lock the seat (see page 53).

Remove the negative (-) cable from the battery negative (-)
terminal; then remove the positive (+) cable from the battery
positive (+) terminal.

Remove the battery from the battery tray.

MAINTENANCE

& ADJUSTMENTS

Inspection
1.

Remove the battery cell caps.

Inspect the electrolyte level of each cell. The electrolyte
level must be maintained between the upper and lower level
indicators.

If the electrolyte level is below the lower indicator, add
distilled water as necessary.

Emergency Procedures
Eyes - Flush with water from as cup or other container for
at least fifteen minutes. (Water uncler pressure can damage
the eye.) Immediately call 911 (USA only) or a physician
immediately.
Skin - Remove contaminated clothing. Flush the skin with
large quantities of water. Call a physician immediately.
Swallowing - Drink water or milk. Call your local Poison
Control Center (USA only) or a physician immediately.

The battery contains sulfuric acid (electrolyte) which is highly corrosive and
poisonous.
Getting electrolyte in your eyes or on
your skin can cause serious burns.
Wear protective clothing and eye protection when working near the battery.

The battery is rated at 14Ah (ampere-hours). 10% of the
ampere-hour rating should be used as the charging current.
A battery charger should be used that can be adjusted to
deliver 1.4 amperes.

The battery gives off explosive hydrogen gas during normal operation.
A spark or flame can cause the battery
to explode with enough force to kill or
seriously hurt you.
Wear protective clothing and a face
shield, or have a skilled mechanic do
the battery maintenance.

Charging the Battery
1. Remove the battery cell caps.
2.

Connect the battery charger following the manufacturer’s
instructions, then charge the battery 3-4 hours.

After the battery is charged, inspect the electrolyte level in
each of the cells. Add distilled water as necessary, then
install the battery caps.

Clean the outside of the battery and the battery
compartment with a solution of baking soda and water.
Don’t allow any of the solution to drip down the vent caps
into the battery cells.

Installation
1.

From the right side of the riding mower, locate where the
rear deck mounting plate attaches to a flat, black link.
Halfway up this link is a rod attached to the height
adjustment lever.

The end of the link pivots on the frame. Where the rod and
link attach, there is a threaded section of the rod where two
locknuts hold a mounting pin in position. The position of this
mounting pin on the rod determines how high the mower
deck is in relation to the height adjustment lever.

If the front blade tip is
measuring too high off the
ground, loosen the lower
self-locking nut and allow
the mower deck to drop
enough to obtain a correct
height measurement.
Tighten the upper locknut
to hold the mounting pin in
this position.

If the front blade tip is measuring too low, loosen the upper
lock nut and thread it upward about 13 mm (l/2 inch), then
use a wrench to turn the lower self-locking nut upward and
raise the mower deck. Continue turning the lower
self-locking nut until a correct height measurement is
obtained. Turn the upper lock nut back down toward the
mounting pin, then tighten it securely.

Sharpening Guidelines
l

Maintain the original angle of the blade (about 30’).
Leave a blunt edge of 0.8 - 1.5 mm (l/32 to l/16 inch).
Do not sharpen to a knife edge, as service life will be
reduced.
Remove an equal amount of material from each end of
the blade to maintain balance.
Do not remove material from the inner area of the
cutting edge. If you need to remove material to restore
the cutting edge, taper the edge toward the tip. Do not
taper beyond l/3 of the blade width.
Do not grind the back side of the blade.
Check the balance of the blade by placing a dowel
through the center hole. Should one end of the blade
drop, remove additional materiall from that end of the
blade to achieve balance.
