INTRODUCTION
Dear Customer!
Thank you for purchasing a Husqvarna Rider. Husqvarna Riders have been designed according to a unique concept with a front
mounted cutting deck and patented rear wheel steering. The Rider is built to give maxim um efficiency even in small and confined
areas. Collected controls and a hydrostatic transmission controlled by pedals also contribute to the machine’s performance.
This Operator’s Manual is a valuable document. Following the instructions (use, service, maintenance, etc.) can considerably
increase the life span of your machine and even increase its resale value.
When you sell your Rider, make sure to give the operator’s manual to the new owner.
The final chapter of this operator’s manual comprises a Service Journal. Ensure that service and repair work is documented.
A well-kept service journal reduces service costs for the season-based maintenance and affects the machine’s resale value.
Take the operator’s manual along when the Rider is left to the workshop for service.
Driving and Transport on Public Roads
Check applicable road traffic regulations before driving and transport on public roads. You should always use approved load
retainers during transport and ensure that the machine is well secured.
Towing
When your machine is equipped with a hydrostatic transmission you should only tow the machine over short distances and at a
low speed, otherwise there is a risk of damaging the transmission.
The power transmission must be disengaged when towing, see “Bypass valves” on page 16.
Use
This ride-on mower is designed to mow grass on open and level ground surfaces. In addition, there is a number of accessories
recommended by the manufacturer that broadens the application area. Please contact your dealer for more information about
which accessories are available. The machine may only be used with the equipment recommended by the manufacturer. All other
types of use are incorrect. The manufacturer’s instructions with regard to driving, maintenance, and repair must be followed
precisely.
IMPORTANT!
The transmission/gearbox guarantee is only valid if the
synchronisation of the front and rear wheels has been
checked and adjusted in compliance with the service
schedule. The system will be damaged if synchronisation
is not carried out.
The machine may only be operated, maintained, and repaired by persons that are fully conversant with the machine’s special
characteristics and safety regulations.
Accident prevention regulations, other general safety regulations, occupational safety rules, and traffic regulations must be
observed.
Unauthorised modifications to the design of the machine may absolve the manufacturer from liability for any resulting personal
injury or property damage.

10 –
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.
• Never allow children to operate the machine.
• 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.
• Handle oil, oil filters, fuel and the battery with care, of
concern for the environment. Follow the local recycling
requirements.
• Electrical shocks can cause injuries. Do not touch cables
when the engine is running. Do not test the ignition
system with your fingers.
WARNING!
The engine and the exhaust system become

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.
Place the wheel blocks in front of and behind the rear
wheels.
• Check and abide by local traffic regulations before
transporting or driving the machine on any road.

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.

In order to ensure that the hydraulic cylinder is in the outer
position, hold the lever in the forward position for one to two
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).
IMPORTANT!
Do not use the fuel tank as a support area.
