Safety
Safe Operation Practices for
Ride-on (riding) Rotary
• Keep in mind that the operator or user is responsible for
accidents or hazards occurring to other people or their
property.
• Do not carry passengers.
• All drivers should seek and obtain professional and
practical instruction. Such instruction should
emphasize:
– the need for care and concentration when working
with ride-on machines;
– 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 wheel grip;
• being driven too fast;
• inadequate braking;
• the type of machine is unsuitable for its task;
• lack of awareness of the effect of ground
conditions, especially slopes;
• incorrect hitching and load distribution.
Lawnmower Machines
This machine meets or exceeds European Standards in
effect at the time of production. However, improper use
or maintenance by the operator or owner can result in
injury. To reduce the potential for injury, comply with
these safety instructions and always pay attention to the
safety alert symbol, which means CAUTION,
WARNING, or DANGER—“personal safety
instruction.” Failure to comply with the instruction may
result in personal injury or death.
Safe Operating Practices
The following instructions are from the CEN standard EN
836:1997.
This product is capable of amputating hands and feet and
throwing objects. Always follow all safety instructions to
avoid serious injury or death.
Training
• Read the instructions carefully. Be familiar with the
controls and the proper use of the equipment.
Preparation
• While mowing, always wear substantial footwear and
long trousers. Do not operate the equipment when
barefoot or wearing open sandals.
• Thoroughly inspect the area where the equipment is to
be used and remove all objects which may be thrown by
the machine.
• Warning—Fuel is highly flammable.
– Store fuel in containers specifically designed for this
purpose.
– Refuel outdoors only and do not smoke while
refuelling.
– Add fuel before starting the engine. Never remove
the cap of the fuel tank or add fuel while the engine
is running or when the engine is hot.
– If fuel is spilled, do not attempt to start the engine
but move the machine away from the area of
spillage and avoid creating any source of ignition
until fuel vapors have dissipated.
– Replace all fuel tanks and container caps securely.
• Never allow children or people unfamiliar with these
instructions to use the lawnmower. Local regulations
can restrict the age of the operator.
• Never mow while people, especially children, or pets
are nearby.
• Replace faulty silencers.
• Before using, always visually inspect to see that the
blades, blade bolts and cutter assembly are not worn or
damaged. Replace worn or damaged blades and bolts in
sets to preserve balance.

Page 4
• On multi-bladed machines, take care as rotating one
blade can cause other blades to rotate.
Operation
• Do not operate the engine in a confined space where
dangerous carbon monoxide fumes can collect.
• Mow only in daylight or in good artificial light.
• Before attempting to start the engine, disengage all
blade attachment clutches and shift into neutral.
• Do not use on slopes of more than
–5 when mowing on side hills;
–10 when mowing uphill;
–15 when mowing downhill.
• Remember there is no such thing as a safe slope. Travel
on grass slopes requires particular care. To guard
against overturning:
– do not stop or start suddenly when going up or
downhill;
– engage clutch slowly, always keep machine in gear,
especially when travelling downhill;
– machine speeds should be kept low on slopes and
during tight turns;
– stay alert for humps and hollows and other hidden
hazards;
– never mow across the face of the slope, unless the
lawnmower is designed for this purpose.
• Before leaving the operator’s position:
– disengage the power take-off and lower the
attachments;
– change into neutral and set the parking brake;
– stop the engine and remove the key.
• Disengage drive to attachments, stop the engine, and
disconnect the spark plug wire(s) or remove the ignition
key
– before clearing blockages or unclogging chute;
– before checking, cleaning or working on the
lawnmower;
– after striking a foreign object. Inspect the
lawnmower for damage and make repairs before
restarting and operating the equipment;
– if the machine starts to vibrate abnormally (check
immediately).
• Disengage drive to attachments when transporting or
not in use.
• Stop the engine and disengage drive to attachment
– before refuelling;
– before removing the grass catcher;
– before making height adjustment unless adjustment
can be made from the operator’s position.
• Reduce the throttle setting during engine run-out and, if
the engine is provided with a shut-off valve, turn the
fuel off at the conclusion of mowing.
• Use care when pulling loads or using heavy equipment.
– Use only approved drawbar hitch points.
– Limit loads to those you can safely control.
– Do not turn sharply. Use care when reversing.
– Use counterweight(s) or wheel weights when
suggested in the instruction handbook.
• Watch out for traffic when crossing or near roadways.
• Stop the blades rotating before crossing surfaces other
than grass.
• When using any attachments, never direct discharge of
material toward bystanders nor allow anyone near the
machine while in operation.
• Never operate the machine with damaged guards or
without safety protective devices in place.
• Do not change the engine governor settings or
overspeed the engine. Operating the engine at excessive
speed can increase the hazard of personal injury.
Maintenance and Storage
• Keep all nuts, bolts and screws tight to be sure the
equipment is in safe working condition.
• Never store the equipment with fuel in the tank inside a
building where fumes can reach an open flame or spark.
• Allow the engine to cool before storing in any
enclosure.
• To reduce the fire hazard, keep the engine, silencer,
battery compartment and fuel storage area free of grass,
leaves, or excessive grease.
• Check the grass catcher frequently for wear or
deterioration.
• Replace worn or damaged parts for safety.
• If the fuel tank has to be drained, this should be done
outdoors.
• On multi-bladed machines, take care as rotating one
blade can cause other blades to rotate.

Gasoline and Oil
Recommended Gasoline
Using Stabilizer/Conditioner
Use a fuel stabilizer/conditioner in the machine to provide
the following benefits:
Use UNLEADED Regular Gasoline suitable for automotive
use (85 pump octane minimum). Leaded regular gasoline
may be used if unleaded regular is not available.
Important Never use methanol, gasoline containing
methanol, or gasohol containing more than 10% ethanol
because the fuel system could be damaged. Do not mix oil
with gasoline.
Danger
In certain conditions, gasoline is extremely
flammable and highly explosive. A fire or
explosion from gasoline can burn you and others
and can damage property.
• Fill the fuel tank outdoors, in an open area,
when the engine is cold. Wipe up any gasoline
that spills.
• Do not fill the fuel tank completely full. Add
gasoline to the fuel tank until the level is 1/4 to
1/2 in. (6 to 13 mm) below the bottom of the
filler neck. This empty space in the tank allows
gasoline to expand.
• Never smoke when handling gasoline, and stay
away from an open flame or where gasoline
fumes may be ignited by a spark.
• Store gasoline in an approved container and
keep it out of the reach of children. Never buy
more than a 30-day supply of gasoline.
• Always place gasoline containers on the ground
away from your vehicle before filling.
• Do not fill gasoline containers inside a vehicle or
on a truck or trailer bed because interior
carpets or plastic truck bed liners may insulate
the container and slow the loss of any static
charge.
• When practical, remove gas-powered equipment
from the truck or trailer and refuel the
equipment with its wheels on the ground.
• If this is not possible, then refuel such
equipment on a truck or trailer from a portable
container, rather than from a gasoline dispenser
nozzle.
• If a gasoline dispenser nozzle must be used, keep
the nozzle in contact with the rim of the fuel
tank or container opening at all times until
fueling is complete.
• Keeps gasoline fresh during storage of 90 days or less.
For longer storage, drain the fuel tank.
• Cleans the engine while it runs
• Eliminates gum-like varnish buildup in the fuel system,
which causes hard starting
Important Do not use fuel additives containing
methanol or ethanol.
Add the correct amount of gas stabilizer/conditioner to the
gas.
Note: A fuel stabilizer/conditioner is most effective when
mixed with fresh gasoline. To minimize the chance of
varnish deposits in the fuel system, use fuel stabilizer at all
times.
Filling the Fuel Tank
1. Shut the engine off and set the parking brake.
2. Clean around the fuel tank cap and remove the cap. Add
unleaded regular gasoline to the fuel tank until the level
is 1/4 to 1/2 in. (6 to 13 mm) below the bottom of the
filler neck. This space in the tank allows gasoline to
expand. Do not fill the fuel tank completely full.
3. Install the fuel tank cap securely. Wipe up any gasoline
that may have spilled.
Checking the Engine Oil Level
Before you start the engine and use the machine, check the
oil level in the engine crankcase; refer to Checking the Oil
Level, page 20.

The Safety Interlock System
Caution
If safety interlock switches are disconnected or
damaged the machine could operate unexpectedly
causing personal injury.
• Do not tamper with the interlock switches.
• Check the operation of the interlock switches
daily and replace any damaged switches before
operating the machine.
Understanding the Safety Interlock
System
The safety interlock system is designed to prevent the
engine from starting unless:
• The power-take-off (PTO) is Off.
• The operator is seated.
• The brake pedal is depressed.
The safety system is designed to stop the engine if:
• You rise from the seat when the clutch/brake pedal is
released.
• You rise from the seat when the PTO is Engaged.
• You shift into reverse with the PTO engaged and the
operating-in-reverse interlock not deactivated.

Setting the KeyChoice Switch to
Operate in Reverse
An interlock feature on the tractor prevents the power take
off (PTO) from operating when backing up. If you shift into
reverse with the PTO engaged (i.e., with mower blades or
other attachment running), the engine will stop. Do not
mow in reverse unless absolutely necessary.
If you need to use the PTO while backing up, you can turn
off this interlock feature using the KeyChoice switch
located near the seat bracket (Fig. 9).

Page 15
Danger
You could back over a child or bystander while the
mower blade or other attachment is engaged and
cause serious injury or death.
• Do not mow in reverse unless absolutely
necessary.
• Do not insert the KeyChoice key unless it is
absolutely necessary.
• Always look backward and down before
backing up.
• Use the KeyChoice switch only if you are certain
no children or other bystanders will enter the
mowing area.
• Be very observant after deactivating the
interlock because the sound of the engine may
prevent you from noticing that a child or
bystander has entered the work area.
• Always remove both the ignition and KeyChoice
keys and put them in a safe place out of the
reach of children or unauthorized users when
leaving the unit unattended.
1. Engage the PTO.
2. Insert the KeyChoice key into the switch (Fig. 9).

described below, have an Authorized Service Dealer repair
the safety system immediately.
1. Move the PTO lever to Engage. Sit on the seat and
rotate the ignition key to Start; the engine should not
crank. If it does, the interlock system is malfunctioning,
and it must be repaired by an Authorized Service
Dealer. If the engine does not crank, proceed to step 2.
2. Move the PTO lever to Disengage. Sit on the seat, and
release the parking brake. Rotate the ignition key to
Start; the engine should not crank. If it does, the
interlock system is malfunctioning and must be repaired
by an Authorized Service Dealer. If the engine does not
crank, proceed to step 3.
3. Sit on the seat, put the PTO lever in the Disengage
position, and the traction control pedal in neutral.
Ensure that the parking brake is engaged. Rotate the
ignition key to Start; the engine should start and
continue to run. Then engage the PTO lever and
carefully rise from the seat; the engine should stop. If
the engine does not stop running, shut the engine off
and have the interlock system repaired by an
Authorized Service Dealer. If the engine shuts off when
you rise from the seat, the interlock system is
functioning correctly and the tractor can be operated
safely.

4. Put the PTO lever in the Disengage position and the
traction control pedal in neutral. Start the engine. While
the engine is running, move the PTO lever to the
Engage position and move the traction control pedal to
reverse. The engine should stop.
5. Put the PTO lever in the Disengage position. Start the
engine. Move the PTO lever to the Engage position and
turn the KeyChoice key and release it. The KeyChoice
warning light should illuminate. Move the PTO lever to
the Disengage position and the KeyChoice warning
light should turn off.
Driving Forward or Backward
The throttle control regulates the engine speed as measured
in RPM (revolutions per minute).
To go forward or backward, release the parking brake; refer
to Releasing the Parking Brake, page 12. Place your foot on
the traction control pedal and slowly press on the top of the
traction control pedal to move forward or on the bottom of
the traction control pedal to move backward. The farther
you move the traction control pedal in either direction, the
faster the machine will move in that direction.
To slow down, release the pressure on the traction control
pedal.
Important To avoid transmission damage, always
release the parking brake before moving the traction control
pedal.
Stopping the Machine
To stop the machine, release the traction control pedal,
disengage the PTO, and turn the ignition key to Off to stop

To Push the Machine
1. Disengage the PTO, stop the engine, and remove the
ignition key.
2. Raise the grass collector to access the drive control rod.
3. Push the drive control rod in and slide it to the left to
lock it in place (Fig. 12). This disengages the drive
system and allows the wheels to turn freely.
4. Lower the grass collector.
5. Disengage the parking brake to push the machine.
To Operate the Machine
1. Raise the grass collector.
2. Slide the drive control rod to the right and pull it out
(Fig. 12). This engages the drive system.
3. Lower the grass collector.
A Recycler cover is included with the tractor. It is used
when you do not wish to bag grass clippings.
Danger
Without the grass deflector, discharge cover, or
complete grass catcher assembly mounted in place,
you and others are exposed to blade contact and
thrown debris. Contact with the rotating mower
blade(s) and thrown debris will cause injury or
death.
• Never remove the grass deflector from the
mower because the grass deflector routes
material down toward the turf. If the grass
deflector is ever damaged, replace it
immediately.
• Never put your hands or feet under the mower.
• Never try to clear the discharge area or mower
blades unless you move the power take off
(PTO) to Off and rotate the ignition key to Off.
Also remove the key and pull the wire off of the
spark plug(s).

Long Grass
If the grass is ever allowed to grow slightly longer than
normal, or if it contains a high degree of moisture, raise the
cutting height higher than usual and cut the grass at this
setting. Then cut the grass again using the lower, normal
setting.
Tips for Mowing Grass
Fast Throttle Setting
For best mowing and maximum air circulation, operate the
engine at Fast. Air is required to thoroughly cut grass
clippings, so do not set the height-of-cut too low or totally
surround the mower by uncut grass. Always try to have one
side of the mower free from uncut grass, which allows air
to be drawn into the mower.
Using the Mower for the First Time
Cut the grass slightly longer than normal to ensure that the
cutting height of the mower does not scalp any uneven
ground. However, the cutting height used in the past is
generally the best one to use. When cutting grass longer
than 15 cm tall, you may want to cut the lawn twice to
ensure an acceptable quality of cut.
Cut 1/3 of the Grass Blade
It is best to cut only about 1/3 of the grass blade. Cutting
more than that is not recommended, unless grass is sparse
or it is late fall when grass grows more slowly.
When Stopping
If the machine must be stopped while mowing, a clump of
grass clippings may drop onto your lawn. To avoid this:
1. With the blade Engaged, move onto a previously cut
area.
2. To disperse the clippings evenly, raise the mower one or
two height-of-cut settings while driving forward with
the blade Engaged.
Keep the Underside of the Mower Clean
Use the washout port to clean clippings and dirt from the
underside of the mower after each use. If grass and dirt
build up inside the mower, cutting quality will eventually
become unsatisfactory.
Blade Maintenance
Maintain a sharp blade throughout the cutting season
because a sharp blade cuts cleanly without tearing or
shredding the grass blades. Tearing and shredding turns
grass brown at the edges, which slows growth and increases
the chance of disease. Every 30 days, check the cutter blade
for sharpness and file down any nicks.
Mowing Direction
Alternate mowing direction to keep the grass standing
straight. This also helps disperse clippings which enhances
decomposition and fertilization.
Mow at Correct Intervals
Normally, mow every 4 days. But remember, grass grows at
different rates at different times. So to maintain the same
cutting height, which is a good practice, mow more often in
early spring. As the grass growth rate slows in mid summer,
mow less frequently. If you cannot mow for an extended
period, first mow at a high cutting height; then mow again
2 days later at a lower height setting.
Avoid Cutting Too Low
If the cutting width of the mower is wider than the mower
you previously used, raise the cutting height one notch to
ensure uneven turf is not cut too short.

through the fuel system (5 minutes).
C. Stop the engine, allow it to cool, and drain the fuel
tank; refer to Draining the Fuel Tank, page 26.

Important Do not store stabilizer/conditioned gasoline
over 90 days.
8. Remove the spark plug(s) and check its condition; refer
to Servicing the Spark Plug, page 25. With the spark
plug(s) removed from the engine, pour two tablespoons
of engine oil into the spark plug hole. Use the electric
starter to crank the engine and distribute the oil inside
the cylinder. Install the spark plug(s); refer to Spark
Plug, page 25. Do not install the wire on the spark

Leave the negative battery cable disconnected from the
battery during storage.
Important The battery must be fully charged to prevent
it from freezing and being damaged at temperatures below
32°F (0°C). A fully charged battery can be stored one
winter season without recharging.
