English
SAFETY INSTRUCTIONS
• Avoid unnecessary turns on slopes, and if it proves
necessary, turn slowly and gradually downward, if
possible. Drive slowly. Do not turn the wheel sharply.
• Watch out for and avoid driving over furrows, holes, and
bumps. It is easier for the machine to ov erturn on uneven
ground. Tall grass can hide obstacles.
• Do not mow near verges, ditches, or banks. The machine
can suddenly overturn if one wheel comes over the edge
of a steep slope or a ditch, or if an edge gives way.
• Do not mow wet grass. It is slippery, and tyres can lose
their grip so that the machine skids.
• T ry not to stabilise the machine by putting your f oot on the
ground.
• When cleaning the chassis, the machine may never be
driven near verges or ditches.
• When mowing, keep away from b ushes and other objects.
• Follow the manufacturer’s recommendations regarding
wheel weights or counterbalance weights to increase
machine stability.

• Be particularly careful near corners, bushes, trees or
other objects that block your view.
Maintenance
• Stop the engine. Prevent the engine from starting by
removing the spark plug cables from the spark plugs or by
removing the ignition key bef ore making any adjustments
or performing maintenance.
• Never fill the fuel tank indoors.
Children
• Serious accidents may occur if you fail to be on guard for
children in the vicinity of the machine. Children are often
attracted to the machine and mowing. Ne v er assume that
children will stay put where you last saw them.
• Keep children away from the mowing area and under
close supervision by another adult.
• Keep an eye out and shut off the machine if children enter
the work area.
• Before and during a reversing manoeuvre, look backw ard
and downward for small children.
• Never allow a child to ride with you. They can fall off and
seriously injure themselves or be in the way for safe
manoeuvring of the machine.
• Petrol and petrol fumes are poisonous and extremely
flammable. Be especially careful when handling petrol, as
carelessness can result in personal injury or fire.
• Only store fuel in containers approved for the purpose.
• Never remove the fuel cap or fill the fuel tank while the
engine is running.
• Allow the engine to cool before refuelling. Do not fill petrol
in the vicinity of sparks or naked flames. Do not smoke.

SAFETY INSTRUCTIONS
• If leaks arise in the fuel system, the engine must not be
started until the problem has been resolved.
• Store the machine and fuel in such a way that there is no
risk of leaking fuel or fuel vapour leading to injury.
• Check the fuel level before each use and leave space for
the fuel to expand, because the heat from the engine and
the sun may otherwise cause the fuel to expand and
overflow.
• Avoid overfilling. If you spill petrol on the machine, wipe up the
spill and wait until it has evapor ated before starting the engine.
If you spill petrol on your clothing, change your clothing.
• Allow the machine to cool before taking any actions in the
engine room.
• Be careful when servicing the battery. Explosive gases
form in the battery. Never perform maintenance on the
battery while smoking or in the vicinity of open flames or
sparks. This can cause the battery to explode and cause
serious injuries.
• Stop and inspect the equipment if you run over or into
anything. If necessary, make repairs before starting.
• Never make adjustments with the engine running.
• The machine is tested and approved only with the
equipment originally provided or recommended by the
manufacturer.
• The blades are sharp and can cause cuts and gashes.
Wrap the blades or wear protective glo ves when handling
them.
• Check the parking brake’s functionality regularly. Adjust
and maintain as required.
• Reduce the risk of fire by removing grass, leaves and
other debris that may have f astened in the machine. Allow
the machine to cool before putting it in storage.
• Make sure all nuts and bolts are tightened correctly and
that the equipment is in good condition.
• Do not modify safety equipment. Check regularly to be
sure it works properly. The machine must not be driven if
protective plates, protective covers, safety switches or
other protective devices are not fitted or are defective.
• Observe the risk of injury caused by moving or hot parts if
the engine is started with the engine cover open or
protective covers removed.
• Do not change governor settings. If you run too fast, you
risk damaging the machine components, see “Technical
Data” on page 45 for highest permitted engine speed.
• Never use the machine indoors or in spaces lacking
proper ventilation. Exhaust fumes contain carbon
monoxide, an odourless, poisonous and highly dangerous
gas.
Transport
IMPORTANT!
The parking brake is not sufficient to lock the machine
during transport. Ensure you secure the machine firmly to
the transporting vehicle.
• 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 an approved trailer to transport the machine.
• To secure the machine on the trailer, two approved
tension belts and four wedge shaped wheel bloc ks should
be used.
Engage the parking brake and tie the tension belts around
stable parts on the machine, e.g. frame or rear wagon.
Secure the machine by tensioning the belts towards the
back and the front of the trailer respectively.

PRESENTATION
Presentation
Congratulations on your choice of an excellent quality product
that will give you great pleasure for many years. This
operator's manual describes P524. The machines are
equipped with a four-stroke V-Twin engine from Kawasaki.
The four-wheel drive machine is equipped with servo steering
and hydraulic lifts.
The power transmission from the engine is handled by a
hydrostatic gearbox, which allows variable variation of the
speed by using the pedals. One pedal to drive forwards and
one pedal to reverse.
Choke Lever
The choke lev er is used f or cold starts in order to provide the
engine with a richer fuel mixture.
For cold starts, the lever shall be moved backwards to its
endpoint.
IMPORTANT! If the temperature is below 0
must be warmed up for at least 10 minutes to heat up the
hydraulic oil and the transmission. Otherwise there is a risk
that the transmission breaks and the service life is reduced.
°
C the machine
Speed control
Throttle control
The throttle is used to control the speed of the engine and
thereby also the rotation speed of the blades.
In order to increase or decrease the engine speed, the control
is moved forwards or backwards respectively.
Avoid idling the engine for long periods, as there is a risk of
carbon build-up on the spark plugs.
The speed of the machine is variably controlled using two
pedals. Pedal (1) is used to travel forwards and pedal (2) to
reverse.

PRESENTATION
Chronometer
The chronometer shows how many hours the engine has
been running.
Any time when the engine is not running but the ignition is
switched on is not registered. The last digit sho ws tenths of an
hour (6 minutes).
Parking brake
The parking brake is activated as follows:
Cutting deck
P524 can be fitted with the Combi 112 and Combi 122 cutting
decks.
The Combi-unit, equipped with a CombiClip plug, finely chops
the cuttings to fertiliser. Without the CombiClip plug the unit
works in the same way as a rear ejection unit. The rear ejector
ejects the clippings behind the unit without finely chopping them.
Lever for h ydraulic lift of attachments
The lifting lever is used to put the cutting deck in either the
transport or mowing position when hydraulic pressure is
available.

seconds after the cutting deck has hit the ground.
English
PRESENTATION
PTO blades on/off
To make the cutters rotate the cutting deck must be lowered
in the mowing position and the “PTO” button activated
(pulled up).
Cutting height adjustment lever
Using the lever, the cutting height can be adjusted to
6 different positions.
The seat springs can be adjusted by moving the rubber blocks
in their brackets on the underside of the seat. Set both b locks
in the front, centre or rear positions.
Refuelling
The engine should be run on 95-octane unleaded petrol (not
mixed with oil). It can be beneficial to use environmentally
adapted alkylate petrol. (max. methanol 5%, max. ethanol
10%, max. MTBE 15%)
Do not fill the tank completely, leave an expansion area of at
least 2.5 cm (1“).
In order to obtain an equal cutting height, it is important that
the air pressure is the same in both front wheels.
Seat
The seat has a hinged mounting on the front edge and can be
folded forwards.
The seat can also be adjusted lengthways.
When making adjustments, the lever under the front edge of
the seat is moved to the left, after which the seat can be
moved backwards or forwards to the desired position.
WARNING!
Petrol is highly flammable. Exercise care
!
and refuel outdoors (see safety
instructions).

DRIVING
Mowing Tips
WARNING!
Clear the lawn of stones and other objects
!
that can be thrown out by the blades.
• Localise and mark large rocks and other fixed objects in
order to avoid collisions.
• Begin with a high cutting height and reduce it until the
desired mowing result is attained.
• The mowing result will be best with the highest permitted
engine speed, see technical data, (the blades rotate
rapidly) and low speed (the Rider moves slowly). If the
grass is not too high and thick, the driving speed can be
increased without noticeably depreciating the mowing
result.
• The finest lawns are obtained by mowing often. Mowing
will be more even and the clippings will be more evenly
distributed across the area. The overall mowing time will
not be longer as higher driving speeds can be selected
without impairing the mowing result.
• Avoid mowing wet la wns. The mo wing result will be poorer
as the wheels will sink into the soft lawn.
• Hose down the cutting deck with water underneath each
time it is used. The cutting deck should then be put in the
service position.
• When the BioClip function is used, it is very important that
the mowing interval is not too long.
Before Starting
• Read the safety instructions and information concerning
the placement of controls and functions before starting.
• Perform daily maintenance before starting as set out in
the Maintenance schedule.
IMPORTANT!
The air intake grille in the engine cover behind the driver’s
seat must not be blocked by, for example, clothing, leaves,
grass or dirt. Impaired cooling of the engine. Risk of major
engine damage.
Starting the engine
1 Make sure the bypass valves are closed on each axle.
2 Engage the parking brake.

WARNING!
Never run the engine indoors, in enc losed or
!
badly ventilated areas. Engine exhaust
fumes contain poisonous carbon monoxide.
DRIVING
IMPORTANT! If the temperature is below 0° C the machine
must be warmed upp for at least 10 minutes to heat up the
hydraulic oil and the transmission. Otherwise there is a risk
that the transmission breaks and the service life is reduced.
Starting the engine with a weak
battery
WARNING!
Lead-acid batteries produce explosive
!
gases. Avoid sparks, open flames and
smoking close to batteries. Always wear
protective glasses in the vicinity of batteries.
If the battery is too weak to start the engine, it should be
recharged.
When jump leads are used for emergency starting, follow the
procedure below:
IMPORTANT!
Your Rider is equipped with a 12-volt system with negative
earth. The other vehicle must also have a 12-volt system
with negative earth. Do not use your Rider battery to start
other vehicles.

English – 19
DRIVING
4 Select the required cutting height (1-6) using the cutting
height lever.
5 Start the blades by activating the PTO button.
Stopping the Engine
If the engine has been worked hard, it is preferab le to let the
engine idle for a minute so it is running at its normal working
temperature when it is stopped. Avoid idling the engine for
long periods, as there is a risk of carbon build-up on the spark
plugs.
1 Shut off the blades with the PTO button
2 Lift the cutting deck using the lifting lever.
In order to obtain an equal cutting height, it is important
that the air pressure is the same in both front wheels.
IMPORTANT!
The life span of the drive belts is increased significantly if
the engine runs at a low speed when the blades are
engaged. Therefore apply full throttle first when the cutting
deck has been moved to the mowing position and the
blades are engaged.
IMPORTANT! If the temperature is below 0° C the machine
must be warmed upp for at least 10 minutes to heat up the
hydraulic oil and the transmission. Otherwise there is a risk
that the transmission breaks and the service life is reduced.
Braking
Release the drive pedals. The machine slows and is stopped
by the drive system. Do not use the parking brake as the drive
brake.

must be 0,75 mm/ 0.030". Adjust as necessary by bending
the side electrode.
5 Reinsert the spark plug, turning by hand to avoid
damaging the threads.
6 Tighten the spark plug, once it touches the seating, with
the spark plug spanner. Tighten the spark plug so that the
washer is compressed. A used spark plug should be
turned 1/8 of a turn from the seated position. A new spark
plug should be turned a 1/4 turn from the seated position.
7 Replace the ignition cable shoe.
Checking the safety system
The rider is equipped with a safety system that prevents
starting or driving under the following conditions.
The engine must only be possible to start when the following
conditions are met:
• Blades shut off, PTO not activated.
• The parking brake is applied.
The engine must stop under any of the following conditions:
• The cutting deck is lowered and the driver stands up.
• The cutting deck is raised, the parking brake is not
engaged and the driver stands up.
Check daily to ensure that the safety system works by
attempting to start the engine when one of the conditions
above is not met. Change the conditions and try again.
Replacing the light bulbs
For information about the bulb type, see “Technical Data” on
page 45.
1 Unscrew the four screws holding the front cover of the

Do not mix different types of oil.
Caution when using oils such as 5W-20, 10W -30 and 10W-40
the engine's oil consumption increases. If these oils must be
used, check the oil level frequently.
Replacing the engine oil
Open the engine cover.
The engine oil should be changed the first time after 8 hours
running time. It should then be changed after e very 100 hours
of running time.
When operating with a heavy load or at high ambient
temperatures, replace every 50 hours.
WARNING!
Engine oil can be very hot if it is drained
!
directly after stopping the engine. Allow the
engine to cool somewhat first.
1 Place a container underneath the engine’s left oil drain
plug.
Check the oil level in the engine, top up if necessary.
IMPORTANT!
Used engine oil is a health hazard and must not be
disposed of on the ground or in nature; it should alw a ys be
disposed of at a workshop or appropriate disposal location.
Avoid skin contact; wash with soap and water in case of
spills.
Changing the oil filter
WARNING!
Engine oil can be very hot if it is drained
!
directly after stopping the engine. Allow the
engine to cool somewhat first.
Open the engine cover.
• Turn the old oil filter anti-clockwise to remove. If
necessary, use a filter remover.
• Lightly lubricate the rubber seal on the new oil filter using
new oil.
• Fit the oil filter by turning clockwise. Turn by hand until the
rubber seal is seated. Now tighten a further half turn.
• Start the engine and let it idle for about 3 minutes. Now
stop it and check for signs of leakage.
• Check the oil level in the engine, top up if necessary.
2 Remove the dipstick. Remove the drain plug from the
engine’s left side.
3 Let the oil run out into the container.
4 Fit the drain plug and tighten it.
5 If necessary fill so that the oil comes up to the FULL mark
on the dipstick. The oil is topped up through the hole the
dipstick sits in.
6 Run the engine warm, then check that there is no leakage
from the oil plug.
IMPORTANT!
Used engine and transmission oil is health-impairing and
must not be disposed of in the ground or in nature.
Replaced filters must be handed in to the workshop or other
allotted place for disposal.
Avoid skin contact; wash with soap and water in case of
spills.

ELECTRICAL AND HYDRAULIC SYSTEMS
Hydraulic System
Keep the hydraulic system clean. Remember to:
• Thoroughly clean before the top-up cap is opened or any connector loosened.
• Use clean containers when topping up the oil.
• Only use pure oil that has been stored in a sealed container.
• Do not reuse drained oil.
• Change the oil and filter according to the intervals specified in Maintenance Schedule.
In order for a hydraulic system to function without problem, it must be free from foreign objects. When used, the system produces
particles, which can cause both wear and abnormal function. In order to remove these particles, the system contains filters. The
filters are sized so as to capture the produced particles, but if contaminants are introduced from outside the system, the filters can
quickly become clogged and fail to function as intended. If there are contaminants in the system, further contamination will be
produced in a self-propagating cycle. The result will be operating disruptions and much work to clean the system.
English – 43
STORAGE
Winter storage
At the end of the mowing season, the Rider should be readied
for storage, likewise 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 clog the
carburettor and disrupt engine function.
Fuel stabilizers are an acceptable option as regards sticky
residues during storage. If alkylate petrol is used, stabilisers
are unnecessary because this fuel is stable. However, you
should avoid s witching between standard and alkylate petrol
as sensitive rubber components can harden. Add stabiliser to
the fuel in the tank or in the storage container. Alw ays use the
mixing ratios specified by the manufacturer of the stabiliser.
Run the engine for at least 10 minutes after adding the
stabiliser so that it will reach the carburettor. Do not empty the
fuel tank and the carburettor if you have added stabiliser.
WARNING!
Never store an engine with fuel in the tank
!
indoors or in poorly ventilated spaces where
fuel vapour can come in contact with open
flames, sparks, or a pilot light such as in a
boiler, hot water tank, clothes drier, etc.
Handle the fuel with care. It is very
flammable and careless use can cause
serious personal injury and property
damage. Drain the fuel into an approved
container outdoors and far away from open
flames. Never use petrol for cleaning. Use a
degreaser and warm water instead.
Guard
There is a cover to protect your machine during storage or
transport. Contact your dealer for a demonstration.
Service
Low season is the most suitable time to perform a service or
overhaul of the machine in order to ensure high function
safety during high season.
When ordering spare parts state your machine’s purchase
year, model, type, and serial number.
Always use genuine Husqvarna spare parts.
An annual check-up or trimming at an authorised service
representative is a good way to ensure that your Rider
performs at its best the following season.
To ready the Rider for storage, follow these steps:
1 Clean the Rider carefully, especially under the cutting
deck. Touch up damaged paint to prevent rust.
2 Inspect the machine for worn or damaged parts and
tighten loose screws and nuts.
3 Change the engine oil; dispose of properly.
4 Empty the fuel tank. Start the engine and let it run so that
even the petrol in the carburettor is emptied.
5 Remove the plugs and pour about a tablespoon of engine
oil into each cylinder. Turn over the engine so that the oil
is evenly distributed and then refit the spark plugs.
6 Lubricate all grease nipples, joints and shafts.
7 Remove the battery. Clean, charge, and store in a cool
place.
8 Store the Rider in a clean, dry place and cover it for extr a
protection.
