• The owner and operator of this equipment can prevent  
accidents and is responsible for accidents or injuries  
occurring to themselves, other people and/or property.  
• Do not put hands or feet near rotating parts or under the  
machine. Keep clear of the discharge opening at all times.  
IMPORTANT INFORMATION The American Academy of  
Pediatrics recommends that children be a minimum of 16  
years of age before operating a riding lawn mower.  
• Only allow responsible adults, who are familiar with the  
instructions, to operate the machine.  
Protecting 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.  
• Clear the area of objects  
such as rocks, toys, wire,  
etc., which could be picked  
up and thrown by the  
blades.  
• Be sure the area is clear  
of bystanders before  
operating. Stop machine if  
anyone enters the area.  
• Do not mow in reverse  
unless absolutely necessary. Always look down and behind  
before and while backing.  
• Never direct discharged material toward anyone. Avoid  
discharging material against a wall or obstruction. Material  
may ricochet back toward the operator. Stop the blades  
when crossing gravel surfaces.  
• Do not operate machine without the entire grass catcher,  
discharge guard, or other safety devices in place and  
working.  
• 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.  
• Slow down before turning.  
• Never leave a running machine unattended. Always turn off  
blades, move the steering control lever outward to the park  
brake position and stop the engine before dismounting.  
• Never carry passengers. The machine is only intended for  
use by one person.  
• Disengage blades when not mowing. Shut off engine and  
wait for all parts to come to a complete stop before cleaning  
the machine, removing the grass catcher or unclogging the  
discharge guard.  
• Never allow children to  
operate the machine.  
• Use extreme care when  
approaching blind corners,  
shrubs, trees, or other  
objects that may block your  
view of a child.  
• Operate the machine only in daylight or good artificial light.  
• Do not operate the machine while under the influence of  
alcohol or drugs.  
• Watch for traffic when operating near or crossing roadways.

SAFETY  
• Always wear eye protection when operating machine.  
• Wear proper Personal Protective Equipment (PPE) while  
operating this machine, including (at a minimum) sturdy  
footwear, eye protection, and hearing protection. Do not  
mow in shorts and/or footwear with open toes.  
WARNING! Do not drive up or down hills with slopes  
greater than 10 degrees. Do not drive across any slopes.  
• 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.  
WARNING! When using the machine, approved  
personal protective equipment should be used. Personal  
protective equipment cannot eliminate the risk of injury  
but it will reduce the degree of injury if an accident does  
happen. Ask your retailer for help in choosing the right  
equipment.  
• Avoid starting, stopping, or turning on a slope. If the tires  
lose traction, disengage the blades and proceed slowly  
straight down the slope.  
• Keep movement on the slopes slow and gradual. Do not  
make sudden changes in speed or direction, which could  
cause machine to roll over.  
• Use extra care while operating machine with grass catchers  
or other attachments; they can affect the stability of the  
machine.  
• Data indicates that operators age 60 years and above are  
involved in a large percentage of riding mower-related  
injuries. These operators should evaluate their ability  
to operate the riding mower safely enough to protect  
themselves and others from serious injury.  
• Do not use on steep slopes.  
• Do not try to stabilize the  
machine by putting a foot  
on the ground.

weights or counterweights.  
• Keep machine free of grass, leaves or other debris buildup  
which can touch hot exhaust or engine parts and burn. Do  
not allow the mower deck to plow leaves or other debris  
which can cause buildup to occur. Clean any oil or fuel  
spillage before operating or storing the machine.  
• Do not mow near drop-offs,  
ditches, or embankments.  
The machine could  
suddenly roll over if a wheel  
is over the edge or the edge  
caves in.  
• Allow machine to cool before storage.  
Safe Handling of Gasoline

SAFETY  
The motion control fault light will blink if the motion control  
levers are not in the neutral (outer) position.  
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 five 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.  
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  
(wilth blinks of a shorter duration) to warn the operator if the  
switch is faulty or has become disconnected.  
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.

CONTROLS  
Steering Control Levers  
WARNING! The machine can turn very rapidly if one  
steering control is moved much further forward than the  
other.  
Park Brake  
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.  
The park brake is integrated with the steering control levers.  
Move the levers outward from the neutral position to engage  
the park brake.  
To release the park brake, rotate both steering control levers  
inwards to the neutral position. Do not attempt to operate the  
unit without both levers being inwards out of the engaged  
position or machine components could be damaged.  
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.  
IMPORTANT INFORMATION The machine must stand  
absolutely still when applying the park brake. Always set  
the park brake before dismounting. Release the park brake  
before moving the mower.  
If the steering controls are in uneven positions when standing  
still or do not fit in the slots for moving the controls outward,  
they can be adjusted.  
Ignition Switch  
The ignition switch is placed on the control panel and is used  
to start and stop the engine.

rotation of the blades, assuming the blade switch is pulled out.  
See Blade Switch.  
The service meter displays the total number of hours the  
engine has run and indicates when the engine and mower  
need servicing.  
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.  
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 minder operates (clocks hours) only when the  
engine is running or when the SmartSwitch is active (unlocked).  
Cold Weather Control  
In temperatures below 32OF, move the throttle control forward  
past the start detent to the snowflake symbol. Once the engine  
has started, slowly move the throttle control back to the full  
throttle position.  
Blade Switch  
To engage the mower deck, pull the knob out; mower blades  
are disengaged when the knob is pressed down.

CONTROLS  
Fuse  
Cutting Height Lever  
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 flat pin type used in automobiles.  
To set the deck cutting height, pull the cutting height lever  
inwards and move it to the desired height notch.  
IMPORTANT INFORMATION Always raise the deck to the  
highest position for transport.  
Seat Adjustment 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.  
Bypass Linkages  
The seat can be adjusted lengthways. When making  
adjustments, the lever under the right side of the seat is pulled  
up, after which the seat can be moved backward or forward.  
Fuel Shut Off Valve  
Transaxle bypass linkages must be engaged when pushing or  
pulling the mower. The release levers are located on each side  
of the rear of the unit below the rear engine guard. See Moving  
Machine By Hand in the Operation section.  
WARNING! Bypass linkages are located close to  
the muffler. To prevent burns, the engine should be shut off  
and allowed to cool before the bypass linkage levers are  
handled.  
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.

CONTROLS  
Fuel Tank  
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 run until the fuel lines and carburetor are  
empty. Use fresh fuel the next season. See Storage for  
additional information. Never use engine or carburetor  
cleaners in the fuel tank or permanent damage may occur.  
Tracking  
WARNING! Gasoline is highly flammable.  
Observe caution and fill the tank outdoors (see the safety  
instruction).  
WARNING! The engine and the exhaust system,  
become very hot during operation. There is a risk for burns  
if touched. Allow engine and exhaust system to cool before  
refueling.  
WARNING! Fill to bottom of filler neck. Do not  
overfill. Wipe off any spilled oil or fuel. Do not store, spill or  
use gasoline near an open flame.  
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 act as limiting devices for 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  
field.  
Read the safety instructions before refueling. The machine has  
one fuel tank, just behind the console. The tank capacity is 3½  
gallons (13.25 litres).  
Regularly check the gas cap gasket for damage and keep the  
cap properly tightened.  
The engine will run on a minimum of 85-octane unleaded  
gasoline (no oil mix). Environmentally adapted alkylate  
gasoline can be used. See also Technical Data concerning  
ethanol fuel. Methanol fuel is not allowed. Do not use E85  
alcohol based fuel. Damage to engine and components may  
occur.  
3. Using a ½" wrench, back the tracking bolts out until flush  
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.  
When operating in temperatures below 32° F. (0° C.), use  
fresh, clean winter grade gasoline to insure good cold weather  
starting.  
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.

OPERATION  
Read the Safety section and following pages, if you are  
unfamiliar with the machine.  
SmartSwitch Ignition  
NOTES: The default passcode [321] is preset at the factory. For  
safety and security, the passcode should be changed prior to  
use.  
Training  
Due to unique steering capabilities, zero turn mowers are far  
more maneuverable than typical riding mowers.  
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 then be lit continuously, signalling the system  
is ready to accept a new code.  
This section should be reviewed in its entirety prior to  
attempting to move the mower under its own power. When  
first 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 should become familiar with the mower’s  
movement on a hard surface, such as concrete or blacktop  
PRIOR to attempting to operate on turf. Until the operator  
becomes comfortable with the mower controls and zero turning  
capability, overly aggressive maneuvers may damage turf.  
Steering  
1
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.  
2
First time users should push the mower (see Moving the  
Machine By Hand in the Operation section) to an open, flat  
area without other people, 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 and disengage the  
park brake by moving the steering control levers inward. Do  
not engage the blades. As long as the control levers have not  
been moved forward or backwards, the mower will not move.  
Slowly move both control levers slightly forward. This will allow  
the mower to move forward in a straight line. Pull the control  
levers back to the neutral position and the mower should stop  
moving.  
3. Using the lower buttons, enter a desired code of numbers  
from one to five 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.  
Pull back slightly on control levers, allowing the mower to  
move backwards. Push the control levers forward 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, complete the turn.

cancer, birth defects or other reproductive system damage.  
The engine exhaust contains carbon monoxide, which is a  
odorless, colorless, poisonous gas. Do not use the machine  
in enclosed spaces.  
5. Move the throttle lever to the full throttle position.  
NOTE: There is a detent at the full throttle position to aid in  
setting the control.  
Starting the Engine  
1. Sit on the seat.  
2. Raise the mower deck to the highest position.  
If the temperature is below 32OF, move the throttle lever  
up to the cold weather (snowflake) 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.  
3. Disengage the mower blades by pressing the blade  
switch downwards.  
IMPORTANT INFORMATION Under normal starting  
conditions, use a press and release method for the ignition  
start/stop switch. Do not press and hold.

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 first start after the unit has sat idle for an  
extended period of time, 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 five seconds),  
allowing time for fuel to be pulled into the engine.

OPERATION  
Mowing Tips  
• Observe and flag rocks and other fixed objects to avoid  
Headlights  
Use Button 2 to turn on/off the headlights. When the  
engine is in start mode, press the button to turn the  
headlights on. A blinking Button 2 light signals that one  
or both headlights are not working.  
The headlights can also be used when the ignition  
switch is not activated or the unit is not running. Press  
Button 2 and the headlights will stay lit for one minute.  
For a longer headlight mode, press and hold the button  
for five seconds. The headlights will flash twice to  
acknowledge and will stay on for five minutes.  
collisions.  
• Begin with a high cutting height and reduce it until the  
desired mowing result is attained. The average lawn should  
be cut to 2½" during the cool season and over 3" during the  
hot months. For healthier and better looking lawns, mow  
often after moderate growth. For best cutting performance,  
grass over 6" in height should be mowed twice. Make the  
first cut relatively high, the second to the desired height.  
• The mowing result will be best with a high engine speed  
(blades rotate rapidly) and low speed (rider moves slowly).  
If the grass is not too long and dense, the driving speed  
can be increased without negatively affecting the mowing  
result.  
• The finest lawns are obtained by mowing often. The lawn  
becomes more even and the grass clippings more evenly  
distributed over the mown area. The total time taken is not  
increased as a higher operating speed can be used without  
poor mowing results.  
• When mowing large areas, start by turning to the right so  
that clippings will discharge away from shrubs, fences,  
driveways, etc. After one or two rounds, mow in the  
opposite direction making left hand turns until finished.  
Operating On Hills  
Read the Safety Instructions Driving on Slopes in the Safety  
section.  
• The slowest speed possible should be used before starting  
up or down hills.  
• Avoid stopping or changing speed on hills and make all  
turns slowly.  
• If stopping is absolutely necessary, pull steering controls  
into the neutral position and the push to the outside of the  
unit to engage the park brake.  
To restart movement, move the steering controls back to the  
neutral position.  
• Avoid mowing wet lawns. The mowing result is poorer  
because the wheels sink into the soft lawn, clumps build,  
and grass clippings fasten under the cowling.  
• Hose the mower deck underside with water after each use.  
When cleaning, the mower deck shall be raised into the  
transport position. Make sure the mower is cooled and the  
engine is off.  
• Press forward to regain forward motion.  
• Use compressed air to clean top surface of the deck.  
Avoid flooding water on top surface, engine and electrical  
components.  
• When the mulching kit is used, it is important that the  
mowing interval is frequent.  
WARNING! Do not drive up or down hills with slopes  
greater than 10 degrees. Do not drive across slopes.  
Never drive the rider on terrain that slopes more than 10  
degrees. Mow slopes up and down, never side to side.  
Avoid sudden directional changes.

OPERATION  
Battery Voltage Light  
A battery voltage light can indicate that voltage is below  
the normal operating power.  
CAUTION! Lead-acid batteries generate explosive  
gases. Keep sparks, flame and smoking materials away  
from batteries. Wear eye protection when around batteries.  
If the battery is low when a start attempt is made, the  
battery indicator button will light up. This is an indication  
the battery should be charged. It will not prevent  
additional start attempts as long as remaining charge  
is capable of cranking the engine. The button can also  
indicate a charge system failure if it lights up during  
operation.  
Weak Battery  
If the battery is too weak to start the engine, it should be  
recharged. (See Battery in the Maintenance section.)  
For emergency starting:  
Jumper Cable Use  
Checking Battery Charge System  
1. Connect each end of the RED cable to the POSITIVE (+)  
terminal on each battery, taking care not to short against  
chassis.  
2. Connect one end of the BLACK cable to the NEGATIVE (-)  
terminal of the fully charged battery.  
3. Connect the other end of the BLACK cable to a good  
CHASSIS GROUND on the mower with the discharged  
battery, away from the fuel tank and battery.  
When unit is in ready mode (blinking green), press  
and hold the battery button for three seconds. The S/S  
button indicator will show red (battery charge level is  
low), multi-colored (battery charge is marginal) or green  
(battery level is good) until the battery button is pressed  
again or is allowed to reset after ten seconds.  
To remove cables, reverse order  
1. Remove BLACK cable first from chassis and then from the  
fully charged battery.  
2. Remove RED cable last from both batteries.  
IMPORTANT INFORMATION The mower is equipped  
with a 12-volt negative grounded system. The other vehicle  
must also be a 12-volt negative grounded system. Do not  
use your mower to start other vehicles.

MAINTENANCE  
Safety System  
Park Brake  
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 deck is disengaged.  
• the steering / park brake controls are in the outer, locked  
neutral position.  
Visually check that no damage is found on the steering control  
levers, links or switches belonging to the park brake. Perform a  
standstill test and check that there is sufficient braking action.  
To adjust the park brake, contact the Husqvarna service  
workshop.  
IMPORTANT INFORMATION The machine must be  
absolutely standing still when applying the park brake.  
WARNING! Faulty adjustment will result in reduced  
braking ability and can cause an accident.  
Tire Pressures  
All tires should be at 15 psi / 103 kPa / 1 bar.  
Make daily inspections to ensure that the safety system works  
by attempting to start the engine when one of the conditions is  
not met. Change the conditions and try again.  
If the machine starts when one of these conditions is not met,  
turn the machine off and repair the safety system before using  
the machine again.  
Make sure the engine stops when the park brake is not  
engaged and the operator leaves the seated position.  
Check that the engine stops if the mower blades are engaged  
and the driver temporarily moves off the drivers seat.  
IMPORTANT INFORMATION DO NOT add any type of  
tire liner or foam fill material to the tires. Excessive loads  
created by foam filled tires will cause premature failures.  
IMPORTANT INFORMATION To be able to drive, the  
driver must sit in the seat and the steering / park brake  
controls must be moved into the engaged (outer) position.  
Otherwise the engine will stop.  
Only use O.E.M. specified tires.

Caster Wheels  
V-belts  
Check every 200 hours. Check that wheels rotate freely. If  
wheels do not rotate freely take the unit to your dealer for  
service.  
Check every 100 hours of operation. Check for severe  
cracking and large nicks.  
NOTE: The belt will show some small cracks in normal  
operation.  
Foam filled tires or solid tires will void the warranty.  
The belts are not adjustable. Replace belts if they begin to slip  
from wear.  
Removal and installation  
Remove nut and caster bolt. Pull the wheel out of the yoke and  
take care of the spacers. Install in reverse order. Tighten caster  
bolt.  
Deck Belt Removal  
1. Park on a level surface. Apply park brake.  
2. Lower the deck into the lowest cutting position.  
3. Remove bolts from belt shields and remove shields.  
4. Remove any dirt or grass that may have accumulated  
around the cutter housings and entire deck surface.  
5. Loosen the nut securing the belt guide. Note the position  
of the belt guide for reinstallation.  
6. Push inward on the idler arm to release the tension on the  
belt.  
Anti-scalp Rollers  
Anti-scalp rollers are properly adjusted when they are just  
slightly off of the ground when the deck is at the desired  
cutting height in the operating position. Anti-scalp rollers then  
keep the deck in the proper position to help prevent scalping  
in most terrain conditions.  
Anti-scalp rollers can be set in four positions. The rollers  
should be approximately ¼" (6.5 mm) from the ground. Do not  
adjust the rollers to support the deck.  
7. Carefully lift the belt over the top of the cutter housing  
pulleys and remove belt from the deck.  
Deck Belt Installation  
NOTE: For ease in installing the deck belt, refer to the  
routing decal on the top of the deck.  
1. Wrap the deck belt around the electric clutch pulley  
located on the engine shaft.  
2. Route the belt forward and up onto the deck.  
3. Place belt around spring loaded idler pulley.  
4. Wrap the belt around the stationary idler pulley and  
around the mandrel housings.  
5. Push inward on the idler arm and carefully route belt over  
stationary idler pulley. Once the belt is properly routed,  
slowly release the idler arm to tension belt.  
6. Double check belt routing to make sure it matches the  
decal affixed to the deck, and the belt does not have any  
twist. Correct if needed.  
IMPORTANT INFORMATION Adjust anti-scalp rollers with  
the mower on a flat level surface.  
7. Tighten the belt guide and replace belt shields on both  
mandrel housings and secure with fasteners.  
NOTE: The belt guide should be perpendicular to the belt  
when installation is complete.  
To avoid deck damage, the anti-scalp rollers must not be  
adjusted to support the deck.

Leveling deck  
Adjust the deck while the mower is on a level surface.  
Make sure the tires are inflated to the correct pressure. See  
Technical Data / Transmission. If tires are under or over  
inflated, the deck cannot be properly adjusted. Raise the deck  
to the highest (transport) position.  
front blade tip does not measure 1/8" to ½" higher in the  
rear—with a 5/8 or adjustable wrench, turn the nuts on the  
front suspension linkage. Clockwise raises the front of the  
mower, counter clockwise will lower the front. Adjust nuts  
until rear of mower deck is positioned level to 1/8" higher in  
the rear than the side-to-side measurement.  
NOTE: For illustration, the front foot rest has been  
removed. The adjustment can be made without removal.  
The deck should be adjusted slightly higher in the rear.  
NOTE: To insure accuracy of leveling procedure, mower deck  
drive belt must be installed prior to leveling deck.  
1. Wear heavy gloves. Turn each blade tip to align front to  
rear with the deck side-to-side.  
NOTE: This will place the mower deck in a standard  
measurement position. Depending on the type of grass  
being mowed or environmental conditions, additional  
adjustments may be required to achieve the desired cut.  
2. Measure from the floor surface up to the bottom of the  
blade tip on the discharge side of the mower deck.  
Record the measurement.  
3. Move to the opposite side, check that measurement is the  
same. If adjustment is required—with a ¾" or adjustable  
wrench, turn the lift link adjustment nuts on either side  
counter clockwise to lower or clockwise to raise. Adjust  
until both measurements are equal.

MAINTENANCE  
Cutting Blades  
Cleaning  
For the best mowing results, it is important that blades are well  
sharpened and not damaged.  
Replace blades that have been bent or cracked when hitting  
obstacles.  
Regular cleaning, especially under the mower deck, will  
increase the machine’s life-span. Make it a habit to clean the  
machine directly after use (after it is cooled), before the debris  
sticks.  
Do not spray water on the top of the mower deck. Use  
compressed air to clean the top side of mower deck. Regularly  
clean the underside of the deck with normal water pressure.  
Do not use a high pressure washer or steam cleaner. Avoid  
spraying engine and electrical components with water.  
Let the service workshop decide whether a blade with large  
nicks can be repaired/ground or must be replaced. Balance  
the blades after sharpening.  
Check the blade mounts.  
For models fitted with a cleanout port, attach the quick connect  
(from the accessory packet) to any garden hose. After mowing,  
snap the hose to the cleanout port and turn on water supply.  
CAUTION! Blades are sharp. Protect your hands  
with gloves and/or wrap blades with a heavy cloth  
when handling.  
The sharpening of blades should be carried out by  
an authorized service workshop.  
Blade replacement  
1. Remove blade bolt by turning counter clockwise.  
2. Install new or resharpened blade with stamped GRASS  
SIDE facing towards ground/grass (down) or THIS SIDE  
UP facing deck and cutter housing.  
3. Seat the blade's opening firmly onto the cutter housing.  
4. Tighten blade bolt securely.  
5. Torque blade bolt to 45-60 ft/lbs (60-81 Nm).  
Restart the mower and engage the blades to use the spinning  
action to wash away debris. Make sure the hose is away from  
the mower blades.  
Do not rinse hot surfaces with cold water. Let unit cool before  
washing.  
CAUTION! Use protective glasses when cleaning  
and washing.  
Hardware  
Check daily. Inspect the entire machine for loose or missing  
hardware.  
IMPORTANT INFORMATION Special blade bolt is heat  
treated. Replace with a Husqvarna bolt if required. Do not  
use lower grade hardware than specified.

LUBRICATION  
Wheel and Deck Zerks  
Use only good quality bearing grease.  
Grease from well-known brand names (petrochemical  
companies, etc.) usually maintains a good quality.  
Front Wheel Mount  
Lubricate 3-4 strokes with a grease gun on each set of wheel  
bearings.  
Front Wheel Bearings  
Lubricate 3-4 strokes with a grease gun on each set of wheel  
bearings.  
12/12 Every year  
1/52 Every Week  
Lubricate with  
grease gun  
Filter change  
Oil change  
Level check  
1/365 Every day  
General  
When lubricating with an oil can, it must be filled with engine  
oil.  
When lubricating with grease, unless otherwise stated, use a  
high grade molybdenum disulphide grease.  
For daily use, the machine should be lubricated twice weekly.  
Wipe away excess grease after lubrication.  
Deck Spindles  
Lower the cutting deck completely.  
Lubricate with a grease gun, 2-3 strokes per spindle.  
It is important to avoid getting lubricant on the belts or  
the drive surfaces of the belt pulleys. Should this happen,  
attempt to clean them with spirits. If the belt continues to slip  
after cleaning, the belt must be replaced. Gasoline or other  
petroleum products must not be used to clean belts.  
IMPORTANT INFORMATION Use minimal lubrication  
and remove excess lubricant so that is does not come into  
contact with belts or belt pulley drive surfaces.  
Transmission  
The transmission is maintenance free with no need for level  
checks or oil changes. If a leak occurs, replace the unit or  
contact your Husqvarna dealer.

STORAGE  
To ready the machine for storage:  
Winter Storage  
1. Thoroughly clean the machine, especially under the  
mower deck. Touch up damage to the paint and spray  
a thin layer of oil on the underside of the mower deck to  
avoid corrosion.  
2. Inspect the machine for worn or damaged parts and  
tighten any nuts or screws that may have become loose.  
The machine should be readied for storage at the end of the  
mowing season or if it will not be in use for more than 30 days.  
Fuel allowed to stand for long periods of time (30 days or  
more) can leave sticky residues that can plug the carburetor  
and disrupt engine function.  
Fuel stabilizers are an acceptable option to prevent the sticky  
residues that can occur during storage.  
3. Change the engine oil; dispose of properly.  
Add stabilizer to the fuel in the tank or in the storage container.  
Always use the mixing ratios specified by the manufacturer  
of the stabilizer. Run the engine for at least ten minutes after  
adding the stabilizer so that it reaches the carburetor. Do not  
empty the fuel tank and the carburetor if stabilizer has been  
added.  
4. Empty the fuel tanks or add a fuel stabilizer. Start the  
engine and allow it to run until the carburetor is drained of  
fuel or the stabilizer has reached the carburetor.  
5. Remove the spark plug and pour about a tablespoon of  
engine oil into the cylinder. Turn over the engine so that  
the oil is evenly distributed and then refit the spark plug.  
6. Lubricate all grease zerks, joints and axles.  
7. Remove the battery. Clean, charge and store the battery in  
a cool place, but protect it from direct cold.  
8. Store the machine in a clean, dry place and cover it for  
extra protection.  
WARNING! Never store an engine with fuel in the  
tank indoors or in poorly ventilated spaces where fuel vapor  
can come in contact with open flames, sparks, or a pilot  
light such as in a boiler, hot water tank, clothes dryer, etc.  
Handle the fuel with care. It is very flammable and can  
cause serious personal injury and property damage. Drain  
the fuel into an approved container outdoors and store far  
away from open flame or sources of ignition. Never use  
gasoline for cleaning. Use a degreaser and warm water.  
Service  
When ordering spare parts, please specify the purchase year,  
model, type, and serial number.  
Always use genuine Husqvarna spare parts.  
An annual check-up at an authorized service workshop is a  
good way to ensure that your machine performs its best the  
following season.
