CAUTION! Use protective glasses
for maintenance work.
Safe Handling of Gasoline
To avoid personal injury or property damage, use
much more care in handling gasoline. Gasoline is
very ammable and the vapors are explosive.
• Extinguish all cigarettes, cigars, pipes, and
other sources of ignition.
• Use only approved gasoline containers.
• Do not remove gas cap or add fuel with
the engine running. Let engine cool before
refueling.
• Do not fuel the machine indoors.
• Do not keep the machine or fuel container
where there is an open ame, spark or pilot light
such as on a water heater or other appliance.
• Before you begin refueling, minimize the risk
of static electricity
by touching a metal
surface.
• Do not ll containers
inside a vehicle or
on a truck or trailer
bed with plastic
liner. Always place
containers on the ground away from the vehicle
when lling.
• Do not overll fuel tank. Replace gas cap and
tighten securely.
• Remove gas-powered equipment from the truck
or trailer and refuel it on the ground. If this is not
possible, refuel such equipment with a portable
container, rather than from a gasoline dispenser
nozzle.

• Do not use the
machine indoors or
in spaces lacking
proper ventilation.
The exhaust
fumes contain
carbon monoxide,
an odorless and
poisonous lethal
gas.
• Make sure that the equipment is in good
condition and that all nuts and bolts, especially
those fastening the blade attachments, are
properly tightened and torqued.
• Maintain or replace safety and instruction labels
as necessary.
• Do not interfere with the intended function of a
safety device or reduce the protection provided
by a safety device. Check their proper operation
regularly. NEVER operate a machine with a
safety device that does not function properly.
• Check grass catcher components and the
discharge guard frequently and replace with
manufacturer’s recommended parts when
necessary.
• Do not change the settings of governors and
avoid running the engine with overly high
engine speeds. If you run the engine too fast,
machine components could be damaged.
• To reduce the risk of re, keep machine free of
grass, leaves or other debris buildup. Clean oil
or fuel spills and remove fuel-soaked debris. Let
machine cool before storing.

10
SAFETY
• Stop to inspect the equipment if you run over or
into anything. If necessary, make repairs before
starting.
• Do not make adjustments or repairs with the
engine running.
• The blades are sharp and can cause cuts and
gashes. Wrap blades or use protective gloves
when handling them.
• Check the park brake’s functionality regularly.
Adjust and service as necessary.
• Do not work with the starter circuit if there is
spilled fuel.
• Make sure that the fuel ller cap is mounted
tightly and no ammable substances are kept in
an open vessel.
• Sparking can occur when working with the
battery and the heavy cables of the starter
circuit. This can cause battery explosion, re
or eye injury. Sparking will not occur after the
grounding cable (normally negative, black) is
removed from the battery.
• Disconnect the grounding cable from the battery
rst and reconnect it last.
• Do not make a bridge short circuit across the
starter relay to run the starter.
• Be very careful when handling battery acid.
Acid on skin can cause serious corrosive burns.
If you spill battery acid on your skin, rinse
immediately with water.
• Acid in the eyes can cause blindness, contact a
doctor immediately.
• Be careful when servicing the battery. Explosive
gases form in the battery. Do not perform
maintenance on the battery when smoking or
near open ames or sparks. The battery can
explode and cause serious injury or damage.
• The machine
is tested and
approved only with
the equipment
originally provided
or recommended by
the manufacturer.
Only use approved
repair parts for the
machine.
• The mulch blades must only be used in familiar
areas when higher quality mowing is desired.
• Regularly clean deck and underside of
deck, avoid spraying engine and electrical
components with water.
IMPORTANT INFORMATION The park brake
is not sufcient to lock the machine in position
during transport. Make sure that the machine
is correctly fastened to the transport vehicle.
Always reverse the machine onto the transport
vehicle to avoid tipping it over.
WARNING! Use much more caution
when loading the machine into a truck or
trailer using ramps. There is the possibility of
dangerous injury or death if the machine falls
off the ramps.
Towing
If machine is equipped with a tow hitch, use much
more caution when towing. Do not let children or
others in or on towed equipment.
Make wide turns to avoid jack-kning. Travel
slowly and leave more distance to stop. Do not
tow on sloped ground. The weight of the towed
equipment may cause loss of traction and loss of
control.
Follow the manufacturer’s recommendation for
weight limits for towed equipment. Do not tow
near ditches, canals, and other hazards.
Spark Arrestor
This mower is equipped with an internal
combustion engine and must not be used on
or near unimproved forested, bush covered
or grassy lands unless the engine’s system is
equipped with a spark arrestor meeting applicable
local or state laws.
Federal laws apply on federal lands.
If a spark arrestor is used, it must be maintained
in effective working order by the operator.
A spark arrestor for the mufer is available
through your authorized Husqvarna dealer.
Transport
• The machine is heavy and can cause serious
crushing injuries. Be extra cautious when it is
loaded on or unloaded from a vehicle or trailer.
• Use full width ramps for loading machine into a
trailer or truck.
• Use an approved trailer to transport the
machine. Operate the park brake by securing
the steering controls in the outboard position
with elastic or ratcheting straps. Turn off the
fuel supply. Fasten the machine down with
approved devices such as bands, chains or
straps.
• Both front and rear tie down straps must be
used and directed down and out from the
machine.

11
SAFETY
Safety System
The machine is equipped with a safety system
that prevents starting or driving under the
following conditions.
The engine can only be started when:
• The mower blades are disengaged.
• The motion control levers are in neutral.
After the machine is started, the engine will
continue to run for ve minutes if the operator
leaves the seat after putting the motion control
levers in neutral. The blades will be disengaged
by the safety system. This allows the operator
to leave the machine momentarily to remove
obstacles from the mowing path.
The blade switch light will blink until the blade
switch is disengaged. See Ignition System
Faults in the Operation section. When the
operator returns to the seat, the blade switch will
need to be reset (pushed down, pulled up ) to re-
engage the blades.
The motion control fault light will blink if the
motion control levers are not in the neutral (outer)
position.
NOTE: The motion control light may also blink
if mowing is done on uneven terrain and where
there is varied operator pressure on the seat.
The switch is also programmed to blink the
motion control light (with blinks of a shorter
duration) to warn the operator if the switch is
faulty or has become disconnected.
• Do not operate this machine on public
roadways.
• Check and abide by local trafc regulations
before transporting the machine on roads.
• Do not tow this machine, it may cause damage
to the drive system.
• Do not tow trailers, etc. with this mower. They
may jackknife or overturn, causing damage to
the mower and possible serious injury to the
operator.
• Load the unit onto truck or trailer by driving up
ramps of suitable strength using a slow speed.
Do not lift! The machine is not intended to be
lifted by hand.
• When loading or unloading this machine, do
not use more than the maximum recommended
operation angle of 10O.

CONTROLS
Forward

Reverse
Park
Brake
Steering 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.
There is a neutral position, which is locked if the
steering controls are moved out.
When both controls are in the neutral position (N),
the machine stands still.
By equally moving both controls forward or
backward, the machine moves in a straight line
forward or backward.
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 more
care when using this maneuver.
If the steering controls are in uneven positions
when standing still or do not t in the slots for
moving the controls out, they can be adjusted.
WARNING! The machine can turn very
rapidly if one steering control is moved much
further forward than the other.

IMPORTANT INFORMATION Failure to bring
the steering / park brake controls inward at the
same time will cause the unit's safety system to
shut the unit down.
The park brake is integrated with the steering
control levers. Move both levers out from the
neutral position to engage the park brake.
To release the park brake, pull both steering
control levers inwards to the neutral position at
the same time. Do not try to operate the unit
without both levers being inwards out of the
engaged position or machine components could
be damaged.
Ignition Switch
The ignition switch is placed on the control panel
and is used to start and stop the engine.

CONTROLS
Blade Switch
To engage the mower deck, pull the knob out;
mower blades are disengaged when the knob is
pressed down.
Service Meter
The service meter displays the total number of
hours the engine has run and indicates when the
engine and mower need servicing.
After every 50 hours of operation, an oil can icon
will appear and stay on for two hours, before an
automatic reset occurs. To service the engine and
mower, see the Service Journal of this manual.
Note: The service meter operates (clocks hours)
only when the engine is running or when the
smart switch is active (unlocked).
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.
To increase or decrease the engine speed, the
control is moved forward or back 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.
Cold Weather Control
In temperatures below 32OF, move the throttle
control forward past the start detent to the
snowake symbol. Once the engine has started,
slowly move the throttle control back to the full
throttle position.

CONTROLS
The 20 amp primary fuse is located on the left
hand side of the machine. It is accessed by tilting
the seat forward. The fuse is a at pin type used
in automobiles.
Fuse
Seat Adjustment Lever
The seat can be adjusted lengthways. When
making adjustments, the lever below the right side
of the seat is pulled up, after which the seat can
be moved backward or forward.
Fuel Shut Off Valve
The fuel shut off valve is located at the right rear
of the seat. The valve is off when the handle tab is
turned perpendicular to the fuel line.
Cutting Height Lever
IMPORTANT INFORMATION To obtain an
even cutting height, it is important that the air
pressure in all tires is 15 psi / 103 kPa / 1 bar.
IMPORTANT INFORMATION Always raise the
deck to the highest position for transport.
To set the deck cutting height, pull the cutting
height lever inwards and move it to the desired
height notch.

CONTROLS
Fuel Tank
WARNING! Fill to bottom of ller neck.
Do not overll. Clean off spilled oil or fuel. Do
not keep, spill or use gasoline near an open
ame.
Read the safety instructions before refueling. The
capacity for each tank is 3-1/2 gallons.
Regularly check the gas cap gasket for damage
and keep the cap correctly tightened.
The engine will operate on a minimum of
87-octane unleaded gasoline (no oil mix).
Environmentally adapted alkylate gasoline can
be used. See Technical Data concerning ethanol
fuel. Methanol fuel is not allowed. Do not use E85
alcohol based fuel. Damage to the engine and
components may occur.
When operating in temperatures below 32° F, use
fresh, clean winter grade gasoline to help insure
good cold weather starting.
WARNING! The engine and the exhaust
system, become very hot during operation.
There is a risk for burns if touched. Let engine
and exhaust system to cool before refueling.
IMPORTANT INFORMATION Experience
indicates that alcohol blended fuels (called
gasohol, ethanol or methanol) can attract
moisture which 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 operate until the fuel lines and
carburetor are empty. Use fresh fuel the next
season. See Storage for additional information.
Do not use engine or carburetor cleaners in the
fuel tank or permanent damage may occur.
Tracking
If the mower is not tracking straight, check the
air pressure in both rear tires. Recommended air
pressure for the rear tires is 15 psi (1 bar).
1. Tracking adjustments are made using the
tracking bolts. The tracking bolts limit the
motion control levers when in the full-forward
position.
2. For preliminary tracking adjustment, move
unit to an open, unobstructed area such as an
empty parking lot or open eld.
3. Using a 1/2" wrench, back the tracking bolts
out until ush with nut.
4. Test operate unit by driving it at full throttle
and the full forward position on both motion
control levers. Gradually turn in the tracking
bolt on the right hand side until the unit
noticeably starts drifting right.
5. Drive forward at full throttle with both motion
control levers in the full forward position.
Gradually turn in the left tracking bolt until unit
tracks straight.

Read the Safety section and following pages, if
you are unfamiliar with the machine.
Training
Due to unique steering capabilities, zero turn
mowers are far more maneuverable than typical
riding mowers.
Review this section fully prior to trying to move the
mower under its own power. When rst operating
the mower or until becoming comfortable with
controls, use a reduced throttle speed and
reduced ground speed. DO NOT move control
levers to the furthest forward or reverse positions
during initial operation.
First time users must become familiar with the
mower’s movement on a hard surface, such as
concrete or blacktop PRIOR to trying to operate
on turf. Until the operator becomes comfortable
with the mower controls and zero turning
capability, overly aggressive maneuvers may
damage turf.
Steering
To move forward and backward
The direction and speed of the mower’s
movements are 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.
First time users must push the mower (see
Moving Machine By Hand in the Operation
section) to an open, at area without other
persons, vehicles or obstacles nearby. To move
the unit under its own power, the operator must
sit in the seat and start the engine (see Before
Starting in the Operation section). Adjust the
engine speed to idle, disengage the park brake
but do not engage the blades at this time. Pull
control levers inward. As long as the control levers
have not been moved forward or backwards, the
mower will not move.
Slowly move both control levers forward slightly.
This will let the mower start moving forward in a
straight line. Pull the control levers back to the
neutral position and stop the mower from moving.
Pull back slightly on control levers, allowing the
mower to move backwards. Push the control
levers forward to the neutral position to stop the
mower from 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, rst 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, complete the turn.
Before Starting
1. Read the sections on Safety and Controls
before starting the machine.
2. Do the daily maintenance before starting (see
Maintenance Schedule in the Maintenance
section).
3. Check that there is sufcient fuel in the fuel
tank.
4. Adjust the seat to the desired position.
The following conditions must be fullled before
the engine can be started:
• The blade switch must be pressed down into
the disengaged position.
• Both steering / park brake controls must be in
the locked (outer) position.
SmartSwitch Ignition
NOTE: The default passcode [321] is preset at
the factory. For safety and security, the passcode
should be changed prior to use.
Resetting ignition system passcode
1. To initialize the ignition system, press the
START/STOP (S/S) button on the ignition
switch or sit on the seat. The blue indicator
will blink, showing the system is operational.
2. Using the lower buttons, press and hold
the (1) and (3) buttons at the same time for
three seconds. The blue indicator will be lit
continuously, signaling the system is ready to

3. Disengage the mower blades by pressing the
blade switch downwards.
4. Move the steering / park brake controls rmly
out to the locked position.
5. Move the throttle lever to the middle throttle
position.
NOTE: There is a detent at the full throttle
position to aid in setting the control.
6. Press and release the S/S button to activate
the ignition switch. Check that the indicator is
blinking blue.
Starting the Engine
1. Sit on the seat.
2. Raise the mower deck to the highest position.
3. Using the lower buttons, enter a desired
code of numbers from one to ve digits and
then press the S/S button. The indicator will
blink green to signal the passcode has been
accepted.
4. If the S/S button blinks red, the passcode
reset has not been accepted. Wait for the S/S
button to return to blinking blue and retry the
programming, starting at Step 1.
If the temperature is below 32OF, move the
throttle lever up to the cold weather (snowake)
starting position.
When the engine has started, move the throttle
lever back to full throttle detent and allow the
engine to warm up for a short period before
operating the unit. Failure to move the throttle
from the cold weather starting position will
result in poor engine performance, smoke and
spark plug fouling.
IMPORTANT INFORMATION Under normal
starting conditions, use a press and release
method for the ignition start/stop switch. Do not
press and hold.
IMPORTANT INFORMATION Either of two
actions will wake up the ignition switch—either
the operator sitting on the seat or pressing the
S/S button.
WARNING! The engine exhaust contains
carbon monoxide, which is a odorless,
colorless, poisonous gas. Do not use the
machine in enclosed spaces.

OPERATION
Running
1. Release the park brake by pulling the steering
/ park brake controls inwards to the neutral
position at the same time.
NOTE: The mower is equipped with an
operator presence system. If the operator
tries to leave the seat with the engine running,
without rst setting the park brake, the engine
will shut off.
2. Lower the mower deck to the desired cutting
height.
Ignition System Faults
The SmartSwitch Ignition is programmed to warn
when any part of the safety system is not being
followed and will not allow the unit to be started
until all system faults are resolved.
7. Enter the pass code and press the S/S button.
The S/S button will flash one slow green blink
if the code is accepted and will change to a
rapid green blink.
If the S/S button has accepted the code but
does not stay lit with a rapid green blink, see
Ignition System Faults.
When the S/S button displays a rapid green
blink, press and release the button once more
to start the engine.
Allow the engine to run at a moderate speed,
approximately mid throttle, for a short time
before use.
NOTE: For the rst start after the unit has been
idle for an extended period, or has been refueled
after being run out of gas, the engine may require
an extended start attempt to reprime the fuel
system. Press and hold down the S/S switch for
three seconds and then release. This will prompt
the engine starter to attempt starting the engine
for up to ten seconds (instead of the normal ve
seconds), allowing time for fuel to be pulled into
the engine.
The blade switch fault light will blink if the blade
control switch has not been disengaged (down
position) or is disconnected.
The motion control fault light will blink if the
motion control levers are not in the neutral (outer)
position.
