This manual identifies potential hazards and has special
safety messages that help you and others avoid personal
injury and even death. Danger, Warning, and Caution are
signal words used to identify the level of hazard. However,
regardless of the hazard, be extremely careful.
Danger signals an extreme hazard that will cause serious
injury or death if you do not follow the recommended
precautions.
Warning signals a hazard that may cause serious injury or
death if you do not follow the recommended precautions.
Caution signals a hazard that may cause minor or moderate
injury if you do not follow the recommended precautions.
This manual uses 2 other words to highlight information.
Important calls attention to special mechanical
information and Note: emphasizes general information
worthy of special attention.
• 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.

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). You may use leaded regular
gasoline 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 6 to
13 mm below the bottom of the filler neck. This
empty space in the tank allows the gasoline to
expand.
• Never smoke when handling gasoline, and stay
away from an open flame or where a spark may
ignite the gasoline fumes.
• 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, refuel such equipment on
a truck or trailer from a portable container, not
from a gasoline dispenser nozzle.
• If you must use a gasoline dispenser, keep the
nozzle in contact with the rim of the fuel tank or
container opening at all times until fueling is
complete.
• It keeps gasoline fresh during storage for up to 90 days.
For longer storage, drain the fuel tank.
• It cleans the engine while it runs.
• It 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 fuel stabilizer/conditioner to the
gasoline.
Note: A fuel stabilizer/conditioner is most effective when it
is mixed with fresh gasoline. To minimize the chance of
varnish deposits in the fuel system, use a fuel
stabilizer/conditioner at all times.
Filling the Fuel Tank
1. Stop the engine and wait for all moving parts to stop.
2. Set the parking brake.
3. Clean around the fuel tank cap and remove the cap.
4. Add unleaded regular gasoline to the fuel tank until the
level is 6 to 13 mm below the bottom of the filler neck.
Do not fill the fuel tank completely full.
Note: This space in the tank allows gasoline to expand.
5. Install the fuel tank cap securely.
6. Wipe up any gasoline that spills.
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 on page 21.

Understanding the Safety Interlock
System
The safety interlock system is designed to prevent the
engine from starting unless:
• You are sitting on the seat.
Caution
Children or bystanders may be injured if they
move or attempt to operate the machine while it is
unattended.
Always remove the ignition key and set the
parking brake when leaving the machine
unattended, even if just for a few minutes.
Important To prevent excessive wear, do not “ride the
brakes.” Shift the ground speed lever to a lower speed so
that you will not have to stop or shift while on the slope.
Pushing the Machine Manually
Important Always push the machine manually. Never
tow the machine because transaxle damage may occur.
1. Shift the ground speed lever to Neutral.
2. Disengage the blade (PTO).
3. Stop the engine and wait for all moving parts to stop.
4. Remove the ignition key.
5. Disengage the parking brake.
• The brake pedal is depressed.
• The blade control (PTO) lever is in the Disengage
position.
The safety interlock system is designed to stop the engine if
you do the following:
• You rise from the seat when the clutch/brake pedal is
released.
• You rise from the seat when the blade control (PTO)
lever is in the Engage position.
• You shift into reverse while the blade control (PTO)
lever is in the Engage position and the
operating-in-reverse interlock is not deactivated.
Setting the KeyChoice Switch to
Operate in Reverse
An interlock feature on the machine prevents the power
take-off (PTO) from operating when you back up the
machine. If you shift the ground speed lever 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 it is absolutely necessary.
If you need to use the blade control (PTO) while backing
up, turn off the interlock feature using the KeyChoice
switch located near the seat bracket (Fig. 10).
Using the Safety Interlock
System
Caution
If the 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.
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 blade (PTO).
2. Insert the KeyChoice key into the switch (Fig. 10).
A red light on the front console (Fig. 11) turns on,

Operating Tips
• For the best performance, operate the engine at the
maximum speed. The mower requires air to thoroughly
cut grass clippings, so do not set the height-of-cut too
low or completely surround the mower in uncut grass.
Always leave one side of the mower free from uncut
grass to allow the air to be drawn into the mower.
• Cut the grass slightly longer than normal to ensure that
the cutting height of the mower does not scalp any
uneven ground. When cutting grass longer than 15 cm
tall, cut the lawn twice to ensure an acceptable
appearance.
• It is best to cut only about 1/3 of the grass blade. Do not
cut more than that unless the grass is sparse or it is late
fall when grass grows more slowly.
• Alternate the mowing direction to keep the grass
standing straight. This also helps disperse clippings and
enhances decomposition and fertilization.
• Grass grows at different rates at different times of the
season. 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.
4. Set the parking brake.
5. Stop the engine and wait for all moving parts to stop.
6. Remove the ignition key.
7. Raise the grass collector and remove the hairpin and
clevis pin that secure the discharge tube to the rear plate
(Fig 13).
8. Move the height of cut lever to the lowest position.
9. Remove the bolt, washer, and nut that secure the 2 strap
ends together (Fig. 15).
10.Move the straps away from the the discharge chute.
Note: Do not remove the straps from the mower
housing.
11. Remove the Recycler cover from the mower housing.
12.Install the discharge chute onto the mower.
13.Raise the grass collector and install the clevis pin and
hairpin to secure the discharge tube to the rear plate
(Fig 13).
14.Install the nut and outer washer that secure the
discharge chute to the discharge tube (Fig. 14).
• If the grass is longer than normal, or if it contains a high
degree of moisture, raise the cutting height higher than
usual, cut the grass at that setting, and then cut the grass
again at the lower, normal setting.
• If you must stop the machine while mowing, you may
leave a clump of grass clippings on your lawn. To avoid
this, do the following:
– Engage the blade and move to a previously cut area.
– Disperse the clippings evenly by raising the mower
1 or 2 height-of-cut settings while driving forward
with the blade engaged.
• 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, the cutting quality will
eventually become unsatisfactory.
• Maintain a sharp blade throughout the season. A sharp
blade cuts grass cleanly without tearing or shredding the
grass blades. Tearing and shredding the grass turns it
brown at the edges, which slows its growth and
increases the chance of disease. Every 30 days, check
the blade for sharpness and file down any nicks.

10.When storing the machine for over 30 days, prepare it
as follows:
A. Add a petroleum based stabilizer/conditioner to the
fuel in the tank according to the instructions from
the stabilizer manufacturer. Do not use an alcohol
based stabilizer (ethanol or methanol).
Note: A fuel stabilizer/conditioner is most effective
when mixed with fresh gasoline and used at all times.
B. Run the engine for 5 minutes to distribute
conditioned fuel through the fuel system.
C. Stop the engine, allow it to cool, and drain the fuel
tank; refer to Draining the Fuel Tank on page 27.
D. Start the engine and run it until it stops.
E. Choke or prime the engine.
F. Start and run the engine until it will not start again.
G. Recycle the old fuel according to local codes.
Important Do not store stabilizer/conditioned gasoline
over 90 days.
11. Remove and inspect the spark plug; refer to Servicing
the Spark Plug on page 25. With the spark plug
removed from the engine, pour 2 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, but do not connect the
wire to the spark plug.
12.Disconnect the negative battery cable. Clean the battery
and battery terminals. Check the electrolyte level and
charge it fully; refer to Servicing the Battery on
page 22. 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
