LAWN TRACTOR SAFETY IMPORTANT SAFETY INFORMATION
Most accidents with lawn tractors can be prevented if you follow all instructions in this manual and on the lawn tractor. 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 lawn tractor blade can throw rocks and other objects with enough force to cause serious injury. Before mowing, carefully inspect the area and remove all stones, sticks, bones, nails, pieces of wire, and other loose objects. Never operate the lawn tractor over gravel or any other loose objects. Be aware if children are in the area; stop the lawn tractor and remove the ignition key to prevent accidental starting.
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.
6
LAWN TRACTOR SAFETY
Refuel with Care
Gasoline is extremely flammable, and gasoline vapor can explode. Allow the engine to cool if the lawn tractor 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 lawn
tractor’s platform and pedals.
Turn Engine Off When Not Operating the Lawn Tractor
If you need to leave the lawn tractor 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 lawn tractor is intended for use on relatively flat terrain. Operating
the lawn tractor on slopes exceeding 10 degrees (17% grade) could
cause the lawn tractor 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.
Mowing Conditions
Mow only in daylight or good artificial light. Do not drive the lawn trac-
tor at night or under poor light conditions.
Mowing Near Roads
Always watch for vehicle traffic when operating the lawn tractor near roads and driveways. Never drive the lawn tractor on public roads.
LAWN TRACTOR SAFETY

SAFETY LABEL LOCATIONS

These labels warn you of potential hazards that can cause serious
injury. Read them carefully. If a label comes off or becomes hard to read, contact your Honda lawn tractor dealer for a replacement.
Stay away if engine has been running.

LAWN TRACTOR SAFETY IMPORTANT MESSAGE TO PARENTS
YOUR CHILD’S SAFETY IS VERY IMPORTANT to Honda. Read this
message if you decide to permit your youngster to operate this lawn tractor. Lawn tractors 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 ster operates this equipment.
The first question you’ll need to ask is whether your youngster is capa­ble of operating this lawn tractor safely. Remember, young people vary widely, and AGE IS NOT THE ONLY FACTOR.
Physically, a youngster must be LARGE ENOUGH AND STRONG
ENOUGH to easily start the lawn tractor 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
lawn tractor. 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 lawn tractor.
If you decide that your son or daughter can handle the lawn tractor
safely, CAREFULLY READ THE OWNER’S MANUAL with your young-
ster. Make sure you both understand all instructions and safety infor-
mation. Also, be sure your youngster wears sturdy shoes and other
protective clothing when operating or handling the lawn tractor.
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 lawn tractor without supervision. An adult should
also be present during refueling and maintenance. Be sure the lawn
tractor is properly maintained and kept in safe 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 lawn tractor.

Instead use the forward or reverse travel pedal.
The choke knob should be pulled out completely when starting a cold
engine and gradually pushed in as the engine warms.
16

PTO Knob

PTO stands for Power Takeoff.
The PTO knob is used to apply
power.to the mower deck (or other attachment). The PTO knob has three positions: OFF, ON and REVERSE IMPLEMENT. ON and OFF are used for normal operation when moving forward.
The spring-loaded REVERSE
IMPLEMENT position allows the mower deck to work when the lawn tractor is operated with the
reverse travel pedal.
Lift Lever
TRANSPORT
Raises mower for transport. FLOAT
Mower should drop to
desired cutting height by
itself. Under normal conditions, mow with lever in FLOAT position.
LOCKOUT
This position locks out the

BEFORE OPERATION
There are three areas to be checked before using the lawn tractor:
l

Check your lawn

l
Check your lawn tractor
l
Are you ready to mow?
These are described in the following sections.
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 blades and thrown is a
potential hazard to you and others. Look for things like stones, sticks, bones, nails, 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 lawn tractor.
20
BEFORE OPERATION

CHECK YOUR LAWN TRACTOR

For your safety and the service life of your equipment, always inspect your lawn tractor before using it. Before beginning your pre-operation checks, be sure:
l
