Personal protective equipment
Slope Operation
Slopes are a major factor related to loss of
control and tip-over accidents, which can
result in severe injury or death. Operation on
all slopes requires extra caution. If you
cannot back up the slope or if you feel uneasy
on it, do not mow it.
• Mow up and down slopes (10 degrees
maxium), not across.
• Watch for holes, ruts, bumps, rocks, or
other hidden objects. Uneven terrain
could overturn the machine. Tall grass
can hide obstacles.
• Choose a low ground speed so that you
will not have to stop while on the slope.
• Do not mow on wet grass. Tires may lose
traction.
• Avoid starting, stopping, or turning on a
slope. If the tires lose traction, disengage
the blades and proceed slowly straight
down the slope.
Mow up and down, not side-to-side
WARNING !
not drive up or down hills
Do
with slopes greater than 10
degrees. And do not drive
across any slopes.
6003-004
• Keep all movement on the slopes slow
and gradual. Do not make sudden
changes in speed or direction, which
could cause the machine to roll over.
English-9
SAFETY INSTRUCTIONS
• Use extra care while operating machine
with grass catchers or other attachments;
they can affect the stability of the
machine. Do not use on steep slopes.
• Do not try to stabilize the machine by
putting your foot on the ground.
• Do not mow near drop-offs, ditches, or
embankments. The machine could
suddenly roll over if a wheel is over the
edge or if the edge caves in.
Children
Tragic accidents can occur if the operator is
not alert to the presence of children. Children
are often attracted to the machine and the
mowing activity. Never assume that children
will remain where you last saw them.
• Keep children out of the mowing area
and in the watchful care of a responsible
adult other than the operator.
• Be alert and turn machine off if a child
enters the area.
• Before and while backing, look behind
and down for small children.
• Never carry children, even with the
blades shut off. They may fall off and be
seriously injured or interfere with safe
machine operation. Children who have
been given rides in the past may
suddenly appear in the mowing area for
another ride and be run over or backed
over by the machine.
• Never allow children to operate the
machine.
• Use extra care when approaching blind
corners, shrubs, trees, or other objects
that may block your view of a child.

Parking brake not activated
2. Motion Control Levers
The machine’s speed and direction are
continuously variable using the two steering
controls. The steering controls can be moved
forward or backward about a neutral position.
Furthermore, there is a neutral position,
which is locked if the steering controls are
moved outward.
When both controls are in the neutral position
(N), the machine stands still.
By moving both controls an equal amount
forward or backward, the machine moves in a
straight line forward or backward respectively.
In order, for example, to turn right while
moving forward, move the right control
towards the neutral position. The rotation of
the right wheel is reduced and the machine
turns to the right.
Zero turn can be achieved by moving one
control backward (behind the neutral position)
and carefully moving the other steering
control forward from its neutral position. The
rotation direction when zero turning is
determined by which steering control is
moved backward behind the neutral position.
If the left steering control is pulled backward,
the machine turns to the left. Use extra care
when using this maneuver.
8011-789

leads to separation and formation of
acids during storage. Acidic gas can
damage the fuel system of an engine
while in storage. To avoid engine
problems, the fuel system should be
emptied before storage of 30 days or
longer. Drain the gas tank, start the
engine and let it run until the fuel lines
and carburetor are empty. Use fresh fuel
the next season. See Storage
Instructions for additional information.
Never use engine or carburetor cleaners
in the fuel tank or permanent damage
may occur.
When operating in temperatures below 32° F.
(0° C.), use fresh, clean winter grade gasoline
to help insure good cold weather starting.

6. By pass linkage
When pushing or pulling the mower, be sure
to engage the IZT (Integraded Zeroturn
Transaxle) bypass linkages. The IZT bypass
linkages are located on the rear of the frame,
below the rear engine guard.
• Raise the deck into the highest cutting
position.
• Pull the IZT bypass linkages out and into
the slots and release so that it is held in
the bypass position.
• To reengage the IZT’s to drive, reverse
the above procedure.

The hour meter displays the total operating
time.
It will flash CHG OIL (Change Oil) at 50 hour
intervals. The flash duration is one hour
before and one hour after the interval. The
CHG OIL icon will come on and shut off
automatically. The hour meter can not be
manually reset.
9. Choke Control
The choke control is used for cold starts in order
to provide the engine with a richer fuel mixture.

11. Throttle Control
The throttle control regulates the engine
speed and thereby the rate of rotation of the
blades, assuming the blade switch is pulled
out, see Engaging the Mower Deck.
In order to increase or decrease the engine
speed, the control is moved forward or
backward respectively.
Avoid idling the engine for long periods, as
there is a risk of fouling the spark plugs.
USE FULL THROTTLE WHEN MOWING, for
best mower performance and battery
charging.
12. Blade switch
In order to engage the mower deck, pull the
knob out; the mower blades are disengaged
when the knob is depressed.

13. Cutting height pedal
The cutting deck height is obtained by
pressing the foot pedal lift arm forward and
releasing the transport latch. Then lower the
deck to the preset height. To raise the deck
push forward on the foot pedal lift arm until
the transport latch locks. The cutting height
range is from 1 1/2" (38 mm) to 4 1/2"
(114 mm) in 1/4" (6.4 mm) increments. The
heights are measured from the ground up to
the blade tip with the engine not running.
To change cutting heights move the pin on
the cutting height plates to the desired height
of cut.
IMPORTANT INFORMATION
In order to obtain an even cutting height it
is important that the air pressure in all
four tires is the same 15 psi (1 bar).

OPERATION
Operation
Read "Safety Instructions" section and following pages, if you are unfamiliar with the machine.
Training
Zero turn mowers are far more manueverable than typical riding mowers due to their unique steering
capabilities.
We suggest when first operating the mower, use a reduced throttle speed and reduced ground speed by
NOT moving control levers to the furthest forward or reverse positions during initial operation, or until
operator becomes comfortable with controls. We also suggest first time users, or new users to ZeroTurn
mowers to become familiar with the mowers movement on a hard surface, such as concrete or blacktop
PRIOR to attempting to operate on turf. Until operator becomes comfortable with mower controls and zero
turning capability, they may damage turf due to over aggressive maneuvers.
To move forward and backward
The direction and speed of the mowers movements is effected by the movement of the control lever(s) on
each side of mower. The left control lever controls the left wheel. The right control lever controls the right
wheel.
IMPORTANT INFORMATION
When control levers are in the reverse
position they return to neutral when
released. This may cause the mower to
suddenly stop.
First time users should push mower (see "Moving by Hand" in the "Operation" section) to an open, flat area,
without other people or vehicles/obstacles near by. In order to move unit under its own power, the operator
must be in the seat, start engine (see " Before Starting" in "Operation" section), adjust engine speed to idle,
disengage park brake, do not engage blades at this time, rotate control levers inward. As long as the
control levers have not been moved forward or backwards, mower will not move. Slowly move both control
levers forward slightly, this will allow mower to start moving forward in a straight line. Pull back on control
levers to the neutral position and mower should stop moving. Pull back slightly on control levers, this will
allow mower to start moving backwards. Push forward on control levers to the neutral position and mower
should stop moving.
To turn to the right
While moving in a forward direction, pull the right lever back towards the neutral position while maintaining
the position of the left lever, this will slow the rotation of the right wheel and cause the machine to turn in
that direction.
To turn to the left
While moving in a forward direction pull the left lever back towards the neutral position while maintaining
the position of the right lever, this will slow the rotation of the left wheel and cause the machine to turn in
that direction.
To zero turn
While moving in a forward direction, first pull both control levers back until the mower stops or slows
dramatically. Then by alternating one lever slightly to the forward position and the other in the reverse
position.
