INTRODUCTION
Dear Customer,
Thank you for choosing a Husqvarna Rider. Husqvarna Riders are built to a unique design with a front-mounted cutting unit and a
patented rear-wheel steering system. Riders are designed for maximum efficiency even in small or confined areas. The closely
grouped controls and pedal-operated hydrostatic transmission also contribute to the performance of this machine.
We hope you will find this operator’s manual very useful. By following its instructions (on operation, service, maintenance, etc.) you
will significantly extend the life of the machine and even its second-hand value.
When you sell your Rider, make sure you pass on the operator’s manual to the new owner.
The last chapter in the operator’s manual consists of a Service Journal. Make sure that all service work and repairs are recorded.
A well-documented service history reduces the costs of seasonal maintenance and influences the second-hand value of the
machine. Bring the operator’s manual with the Rider when bringing it to a workshop for service procedures.

Driving and transport on public roads
Check the relevant road traffic regulations before driving the machine on a public road. If transporting the machine on another
vehicle always use approved securing devices and make sure that the machine is securely held.

Towing
When your machine is equipped with a hydrostatic transmission you should, if necessary, 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 the instructions under the heading Clutch control.

Use
This machine is designed solely for cutting grass on conventional lawns and other cleared and leveled ground without obstacles,
as rocks, stumps etc., and, in conjunction with accessories supplied by the manufacturer even for other special tasks for which
instructions are delivered with the accessory. Use in any other way is considered as contrary to the intended use. Compliance with
and strict adherence to the conditions of operation, service and repair as specified by the manufacturer also constitute essential
elements of the intended use.
This machine should be operated, serviced and repaired only by persons who are familiar with its particular characteristics and
who are acquainted with the relevant safety procedures.
Accident prevention regulations, all other generally recognised regulations on safety and occupational medicine, and all road traffic
regulations must be observed at all times.
Any arbitrary modifications carried out to this machine may relieve the manufacturer of liability for any resulting damage or injury.

SAFETY INSTRUCTIONS
•

Never allow children or other persons not trained in the
use of the machine to use or service it. Local laws may
regulate the age of the user.

Driving on slopes
Driving on slopes is one of the operations where the risk of
the driver losing control of the machine or of it overturning is
the greatest; this can result in serious injury or death. All
slopes demand extra care. If you cannot reverse up a slope or
if you feel unsure, do not mow it.
IMPORTANT INFORMATION
Do not drive down slopes with the unit raised.

This is what you do

!

WARNING! You must use approved personal
protective equipment whenever you use the
machine. Personal protective equipment
cannot eliminate the risk of injury but it will
reduce the degree of injury if an accident
does happen. Ask your dealer for help in
choosing the right equipment.

•

Use hearing protection to minimise the risk of hearing
impairment.

•

Wear approved protective glasses or full-face visor during
assembly and when operating.

•
•

•

Never wear loose fitting clothes that can catch in moving
parts.
Never use the machine when barefoot. Always wear
protective shoes or protective boots, preferably with steel
toes.

•

Remove obstacles such as stones, branches, etc.

•

Mow upwards and downwards, not sideways.

•

Do not use the machine on ground that slopes more than
10°.

•

Avoid starting or stopping on a slope. If the tyres start to
slip, stop the blades and drive slowly down the slope.

•

Always drive smoothly and slowly on slopes.

•

Do not make any sudden changes in speed or direction.

•

Avoid unnecessary turns on slopes, if necessary, turn
slowly and gradually downwards 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 overturn on uneven
ground. Tall grass can hide obstacles.

•

Take extra care if any attachments are fitted that can
change the stability of the machine.

•

Do not mow too close to edges, 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.

Make sure that you have first aid equipment close at hand
when using the machine.

Parking brake

Congratulations on your choice of an excellent quality product
that will give you great pleasure for many years. This
operator’s manual describes Rider 175 and Rider 175 AWD.

The parking brake is applied as follows:

The machines are equipped with a 17,5 horse power engine
from Briggs & Stratton.
Rider 175 AWD is equipped with all wheel drive.
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 for driving forward and one for reverse.

Throttle control/choke control

1

Press down the parking brake pedal (1).

The throttle control regulates the engine speed, and thereby
also the rotation speed of the blades.

2

Press in the lock button (2) on the steering column.

3

Release the parking brake pedal while keeping the button
pressed in.

The control is also used to activate the choke. When the
choke is engaged a richer fuel and air mixture is fed to the
engine, which facilitates starting in the cold.

The parking brake lock disengages automatically when the
brake pedal is pressed.

Cutting unit
Rider 175 and 175 AWD can be equipped with two different
cutting units.

Speed limiter
The speed of the machine is steplessly regulated with two
pedals. Pedal (1) is used to drive forwards, and pedal (2) to
drive backwards.

Combi 1120 mm/44”

The Combi-unit, equipped with a BioClip-plug, finely chops
the cuttings to fertiliser. Without the BioClip-plug the unit
works in the same way as a rear ejection unit.

Lifting lever for the cutting unit
The lift lever is used to set the cutting unit in transport or
mowing position.
If the lever is pulled backwards the unit is raised and the
blades automatically stop rotating (transport position).

WARNING! Clear the lawn from stones and
other objects which can be thrown out by
the blades.

•

Localise and mark stones and other fixed objects to avoid
collision.

•

Start with a high cutting height and reduce down until the
required mowing results are obtained.

•

The mowing results are best with a high engine speed
(fast rotating blades) and low driving speed (slow moving
machine). If the grass is not too high and thick, the driving
speed can be increased without noticeably depreciating
the mowing result.

•

The best lawns are achieved if the grass is cut often.
Mowing becomes more uniform and the grass cuttings
become more evenly distributed over the surface. The
total time consumption is not greater since it is possible to
select a higher driving speed without inferior mowing
results.

•

Avoid mowing a wet lawn. The mowing results are inferior
since the wheels sink down into the soft lawn.

•

Hose down the cutting unit with water underneath each
time it is used. The cutting unit 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.

!

WARNING! Do not use the machine on
ground that slopes more than 10°°. Mow
slopes upwards and downwards, never
across. Avoid sudden changes in direction.

Clean the air intake grille in the engine cover behind the
driver’s seat.

Do not use any other type of fuse when replacing.

Open the engine cover.

A blown fuse is indicated by a burnt connector. Pull the fuse
from the holder when replacing.

Check that the cooling intake is free from leaves, grass and
dirt.

The fuse is there to protect the electrical system. If it blows
again shortly after replacement, it is due to a short circuit,
which must be fixed before the machine can be put into
operation again.

Check the air duct, located on the inside of the engine cover,
ensure it is clean and does not rub against the cooling air
intake.
A blocked cooling intake will interfere with the cooling of the
engine, which can damage the engine.

Checking the tyre pressure
The tyre pressure should be 60 kPa (0.6 kp/cm2/8.5 PSI) all
round. To improve driving the pressure on the rear tyres can
be reduced to 40 kPa (0.4 kp/cm2/5.6 PSI). The maximum
tyre pressure is 100 kPa (1,0 kp/cm2/14 PSI).

IMPORTANT INFORMATION
Used engine oil is a health hazard and must not be
disposed of on the ground or in nature; it should always be
disposed of at a workshop or appropriate disposal location.
Avoid skin contact; wash with soap and water in case of
spills.

ADD

FULL

Changing the oil filter
The oil is topped up through the hole the dipstick sits in. Fill
the oil slowly.
Tighten the dipstick correctly before starting the engine. Start
and run the engine at idling speed for approx. 30 seconds.
Turn off the engine. Wait 30 seconds and check the oil level.
If necessary fill so that the oil comes up to the FULL mark on
the dipstick.

The oil filter must be replaced after every 200 hours running
time. Turn the old oil filter anti-clockwise to remove. If
necessary, use a filter remover.

First and foremost use synthetic engine oil class SJ-CF 5W/
30 or 10W/30 for all temperature ranges. Mineral oil SAE30,
class SF–CC can be used at temperatures > +5 °C (40 °F)
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
The engine oil should be changed the first time after 5 hours
running time. It should then be changed after every 50 hours
of running time. When operating with a heavy load or at high
ambient temperatures, replace every 25 hours.

!

WARNING! Engine oil can be very hot if it is
drained directly after stopping the engine.
Allow the engine to cool somewhat first.

30 – English

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.
Fill with new oil according to Checking the engine’s oil level.
Start the engine and let it idle for about 3 minutes. Now stop
it and check for signs of leakage. Fill with oil to compensate
for the oil held in the new oil filter.

Lubrication
Checking the transmission oil level

General lubrication

1

All joints and bearings are lubricated using molybdenum
disulphide grease during manufacture. Continue to lubricate
using the same type of grease *. Lubricate the steering and
control wires using engine oil.

Remove the transmission cover. Undo the two screws
(one on each side) and lift off the transmission cover.

Carry out this lubrication regularly; with daily use, the
machine should be lubricated twice weekly.
*Grease from well-known brand names (petrochemical
companies, etc.) usually maintains a good quality. The most
important property is that the grease provides good
protection against corrosion.

2

Check that there is oil in the transmission’s oil tank.

Rider 175 Fill if necessary with engine oil SAE 10W/30
(class SF–CC).
Rider 175 AWD Fill if necessary with engine oil SAE 10W/
40 (class SF–CC).
The oil and filter should be changed by an authorised service
representative, as described in the Workshop Manual.
Work on the system entails particular demands on
cleanliness and the system must be vented before the
machine is used.

Lubricating the belt adjuster
The belt adjuster should be lubricated regularly using good
quality molybdenum disulphide grease*.
Lubricate using a grease gun, 1 nipple from the right-hand
side under the engine’s lower belt pulley, until grease is forced
out.

With daily use, lubrication should be carried out twice weekly.

Storage
Winter storage

Guard

At the end of the season, or if the machine is going to stand
idle for more than 30 days, it should immediately be made
ready for storage. Fuel which is left to stand for long periods
(30 days or more) can leave tacky deposits which can block
the carburettor and interfere with the engine.

There is a cover to protect your machine during storage or
transport. Contact your dealer for a demonstration

Fuel stabiliser is an acceptable alternative to avoid tacky
deposits during storage. If alkylate petrol (Aspen) is used
stabiliser is not necessary since this fuel is stable. However,
one should avoid changing from standard to alkylate petrol
since sensitive rubber parts can harden. Add stabiliser to the
fuel in the tank or the storage container. Always use the
mixing ratios indicated by the manufacturer. 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
carburettor if stabiliser has been added.

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.

!

Service

When ordering spare parts state your machine’s purchase
year, model, type, and serial number.
Always use genuine parts.
Annual inspection or tuning by an authorised service
workshop is a good way of getting the best out of your
machine the next season.

WARNING! Never place an engine with fuel
in the tank indoors or in poorly ventilated
areas where petrol fumes can come into
contact with naked flames, sparks or pilot
flames in boilers, hot water heaters, drying
cabinets, etc. Exercise caution when
handling fuel. It is highly inflammable, and
careless use can cause serious injury and
damage to property. Drain off the fuel in an
approved container outdoors and well clear
of naked flames. Never use petrol for
cleaning purposes. Use degreasing agents
and hot water instead.

To prepare the machine for storage follow these instructions:
1

Carefully clean the machine, especially under the cutting
unit. Touch-up paint damage to avoid rust.

2

Inspect the machine for worn or damaged parts and
tighten loose screws and nuts.

3

Change the engine oil, and take care of the waste oil.

4

Empty the fuel tank. Start the engine and run it until the
carburettor is emptied of fuel.

5

Remove the plugs and pour about a tablespoon of engine
oil into each cylinder. Pull round the engine to distribute
the oil and screw the plugs back on.

6
