Safety regulations
General instructions
The workshop handbook is written for personnel who
are assumed to have general ride-on mower repara-
tion and service know-how.
The workshop where the ride-on mower is repaired
should be equipped with safety devices in
accordance with local regulations.
No-one should attempt to repair the ride-on mower
without having first read and understood the contents
of this handbook.
The machine is tested and approved only with the
equipment originally provided or recommended by
the manufacturer.
The below-mentioned boxes are included in this
workshop handbook, as is appropriate.
Special instructions
The fuel used in the ride-on mower has the
following hazardous characteristics:
• Toxic fluid and fumes
• Can cause eye and skin complaints
• Can cause breathing difficulties
• Highly flammable
When using compressed air, do not direct the
compressed air stream towards your, or anybody
else's, body. Air can be forced into the blood
stream, thereby constituting a danger to life.
Use eye protection when working with tensioned
springs.
Use hearing protectors when test driving.
After test driving, do not touch the silencer before it
has cooled down. Risk of burn injuries. This
especially applies if the ride-on mower is equipped
with a catalytic converter. If consumed, the lining on
and in the catalytic converter element is dangerous
to health. Use protective gloves when working with
the catalytic converter/silencer.
The blades are sharp and can cause cutting
injuries. Always use protective gloves when you are
handling the blades.
Use protective glasses when working with the
mowing deck. If the belt's tension spring comes off
and flies upwards, this can cause injury to persons.
Use eye protection when working with the battery
with the plugs removed.
Be extra careful when handling battery acid. Spilling
acid on the skin can cause severe burn injuries. If
acid is spilt on the skin, rinse immediately with
water. If acid gets into the eyes, this can cause
blindness. Contact a doctor.
Be careful with the maintenance of the battery.
Explosive gas is formed in the battery. Never
handle the battery when smoking or in the vicinity of
naked flames or sparks. Otherwise, the battery can
explode and cause severe injuries.
IMPORTANT INFORMATION
This box indicates a risk of damage to the
material if the instructions are not
followed.
WARNING!
The warning box indicates a risk
of injury to persons if the
instructions are not followed.
IMPORTANT INFORMATION
Waste oil and old filters should be handled
as hazardous waste.

in everybody’s interest:
•The customer is satisfied with their Rider. He/she
knows where to go to get help if problems occur.
•You have a regular customer, who recommends
you and your company to other potential
customers.
•In this way we build our trademark together, and
take joint responsibility for our products and
customers.
Make sure the paper work is in good order.

make sure that the customer gets the right
Operating Instructions for their machine.
Keep a customer register so that in future you can
see which machines customers have, including all
the serial numbers. This register will benefit you
when ordering spare parts and for future marketing.
In conjunction with the delivery you should also
give the customer the information required to
ensure the safe handling and care of their machine.
Pay special attention to informing the customer
about:
•Safety instructions.
•Controls. Emphasise that one does not push in
the reversing lock on Rider 11 when engaging
the neutral position (start lock function).
•Checking of oil levels. Replenishing of oil, and
which type of oil is required.
•First oil change after the running-in period.
•The need for, and advantages of, following the
service schedule and regularly handing in their
Rider for service.
•Which fuel should be used.
•Mowing tips to get good results. Applications for
BioClip.
•Which accessories are available for the type of
Rider in question.
•Warranty regulations.
•Your company, and who the customer can turn to
if problems occur.
Packaging and unpacking
On delivery from the factory the Rider is normally
packed in special packaging. This consists of a
wooden bottom board with a top part consisting of
heavy-duty cardboard held together by plastic film.
The bottom board is provided with pallet feet and
the goods can be handled with a normal fork-lift
truck from the long side. To keep the goods as level
as possible, two men should help the truck driver.
Lift the machine and drive the truck carefully.
Undo the plastic film and lift off the cardboard
sections. The Rider is placed on the bottom board,
braked and secured with wooden blocks.
Check that there is no transport damage after
removing the packaging. Report any damage to the
transport company in accordance with the standard
routines.
The packaging should not be returned.

Delivery measures
Check that there is oil in the transmission’s oil tank.
Fill if necessary with engine oil SAE 10W/30 (class
SF–CC).
Wheels
Fit the wheels (certain markets). The tyre pressures
should be 60 kPa (0.6 kp/cm2)/8,5 PSI) on all the
wheels.
To improve the driving capacity the pressure in the
back tyres can be reduced to 40 kPa (0.4 kp/cm2)/
5,6 PSI).
Maximum permitted pressure is 100 kPa (1.0 kp/cm2)/14
PSI).
Checking the oil level in the
transmission
Remove the transmission cover. Loosen both
screws (one on each side) and lift off the
transmission cover.
Checking and adjusting of the mowing
deck’s ground pressure and parallelism
Carried out after checking the tyre pressures. See
respective sections in this Workshop Manual.
IMPORTANT INFORMATION
Check and top up with oil after each test
drive. The oil level will drop if there are air
pockets in the transmission.
IMPORTANT INFORMATION
Different pressures in the front tyres will
cause the blades to cut the grass at
different heights.

overhead valve engines with pressure lubrication
and separate oil filters. Engines that are equipped
with catalytic converters reduce hydrocarbon and
nitrogen oxide emissions by up to 65% and carbon
monoxide emissions by up to 45%.
Engine
New Husqvarna Rider professional machines have
two-cylinder, air-cooled engines from Kawasaki.
Major engine repairs are not described in this
workshop manual. This information can be read in
Kawasaki’s own manuals, which contain detailed
information on the adjustment and repair of the
engines. The manuals can be ordered at an
authorised service workshop.

Design and function
Steering
All ride-on lawn mowers in the Rider series have articulated steering. The steering force from the steering
wheel is transferred to the rear section via wires and a chain. This ensures that the ride-on mower is easy to
manoeuvre, as well as having high-precision steering. A Rider easily cuts around all obstacles that may be
found on the lawn.
Thanks to the articulated steering there is a very small turning radius and the uncut circle with a fully turned
wheel is only 20-30 cm, depending on the model.
Rider Pro 18 is fitted with servo steering. Other machines only have the mechanical steering system, as
illustrated below.
Illustration of the mechanical function of the articulated steering.
The illustration shows Pro 18, other machines do not have the power steering in the steering column.
Illustration of the hydraulic function of the articulated steering on Pro 18.
The servo steering obtains its pressure from the pump in the hydrostatic transmission. The power steering is
mounted in the steering column and its stator section is fitted in the power steering housing, which is the
front section of the machine’s frame.
The power steering is, in principle, a hydraulic torque motor controlled by the steering wheel. When there is
no hydraulic pressure, the machine can still be steered, as the steering shaft is mechanically attached to the
sprocket wheel on the power steering’s outgoing shaft (the rotor section).
