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 articulated steering. 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.  
This operator’s manual is a valuable document. 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 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.

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.  
This is what you do  
Remove obstacles such as stones, branches, etc.  
Mow upwards and downwards, not sideways.  
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.  
Do not use the machine on ground that slopes more than  
10°.  
!
Take extra care if any attachments are fitted that can  
change the stability of the machine.  
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.  
Use hearing protection to minimise the risk of hearing  
impairment.  
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.  
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.  
Make sure that you have first aid equipment close at hand  
when using 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.  
Do not try to stabilize the machine by putting your foot on  
the ground.  
Driving on slopes  
When cleaning the chassis, the machine may never be  
driven near verges or ditches.  
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.  
When mowing, keep away from bushes and other objects.  
IMPORTANT INFORMATION  
Do not drive down slopes with the unit raised.

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.  
IMPORTANT INFORMATION  
Never remove the fuel cap and fill the fuel tank when the  
engine is running.  
Wheel weights fitted on the rear wheels are recommended  
when driving on slopes for safer steering and improved  
manoeuvrability. Consult your dealer concerning the use of  
wheel weights if you are unsure. Wheel weights can not be  
used on AWD-machines. Use counterweights.  
Allow the engine to cool before refuelling. Do not smoke.  
Do not fill with fuel in the vicinity of sparks or naked  
flames.  
Handle oil, oil filters, fuel and the battery carefully, of  
environmental considerations. Follow the local recycling  
requirements.  
Children  
Electrical shocks can cause injuries. Do not touch cables  
when the engine is running. Do not test the ignition  
system with your fingers.  
Serious accidents may occur if you fail to be on your guard  
for children in the vicinity of the machine. Children are  
often attracted to the machine and mowing. Never  
assume that children will remain where you last saw them.  
WARNING! The engine and the exhaust  
system become very hot during operation.  
Risk of burn injuries if touched. When  
mowing, keep away from bushes and other  
materials in order to avoid a heating effect.  
Keep children away from the area to be mowed 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 reversing procedures, look behind you  
and down for small children.  
If leaks arise in the fuel system, the engine must not be  
started until the problem has been resolved.  
Never allow children to ride along. They can fall off and  
seriously injure themselves or be in the way for safe  
manoeuvring of the machine.  
Store the machine and fuel in such a way that there is no  
risk that leaking fuel or fumes can cause any damage.  
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.  
Never allow children to operate the machine.  
Avoid overfilling.If you spill petrol on the machine, wipe up  
the spill and wait until it has evaporated before starting the  
engine. If you spill on your clothing, change your clothing.  
Allow the machine to cool before performing any actions  
in the engine compartment.  
Take care with battery maintenance. 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.  
Be particularly careful near corners, bushes, trees or  
other objects that block your view.  
Maintenance  
Stop the engine. Prevent starting by removing the ignition  
cable from the spark plug or remove the ignition key  
before making any adjustments or carrying out  
maintenance.  
Never fill the fuel tank indoors.  
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 cowlings removed.

Presentation  
Congratulations on your choice of an excellent quality product  
that will give you great pleasure for many years. This  
operator’s manual describes Rider 318 and Rider 320 AWD.  
Cutting unit  
Rider 318 and Rider 320 AWD can be equipped with three  
different cutting units.  
Rider 320 AWD is equipped with all wheel drive.  
The power transmission from the engine is handled by a  
hydrostatic transmission, which allows variable variation of  
the speed by using the pedals.  
One pedal for driving forward and one for reverse.  
Throttle control/choke control  
The throttle control regulates the engine speed, and thereby  
also the rotation speed of the blades.  
Combi 94  
Combi 103  
Combi 112  
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 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).  
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.

Cutting tips  
Stop the engine  
Preferably allow the engine to idle for a minute to obtain  
normal working temperature before stopping it if it has been  
working hard. Avoid idling the engine for long periods, as  
there is a risk of carbon build-up on the spark plugs.  
1
Lift up the cutting unit by pulling the lever backwards to its  
locked 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.  
2
Move the throttle control to the MIN. position. Turn the  
ignition key to the ”STOP”.  
Start with a high cutting height and reduce down until the  
required mowing results are obtained.  
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.  
START  
START  
3
When the Rider is at a standstill, press down the parking  
brake and push in the locking button.  
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

Left-hand fender  
Oily dirt can be removed using a cold degreasing agent.  
Spray on a thin layer.  
Loosen the screws holding the wing cover and lift off the  
cover.  
Rinse at normal water pressure.  
Do not direct the jet towards electrical components or  
bearings.  
Do not rinse hot surfaces such as the engine and exhaust  
system.  
It is recommended that you start the engine and run the  
mower for a short period after cleaning, so that any remaining  
water is blown off.  
Checking and adjusting the steering  
wires  
Lubricate the machine if necessary after cleaning. Carry out  
extra lubrication when the bearings have been exposed to a  
degreaser or a water jet.  
The steering is controlled by means of wires.  
These can in time become slack, which implies that the  
adjustment of the steering becomes altered.  
IMPORTANT INFORMATION  
Check and adjust the steering as follows:  
Avoid using a high pressure washer or a steam cleaner.  
Remove the frame plate by loosening the two screws.  
There is a major risk of water penetrating into bearings and  
electrical connections. Corrosion attack can result, which will  
lead to running problems. Cleaning additives generally  
aggravate the damage.  
Removing of the machine hoods  
Engine cover  
The engine becomes accessible for service when the engine  
cover is opened.  
Check the tension of the steering wires by squeezing  
them together by the arrows as illustrated. It should be  
possible to push them together so that the distance  
between them is half as much, without using unnecessary  
force.  
Fold the seat forward, loosen the snap lock under the seat  
and fold the cover backwards.

3
Remove the ignition cable shoe and clean around the  
spark plug.  
Do not use any other type of fuse when replacing.  
Remove the spark plug with a 3/4” (19 mm) spark plug  
socket wrench.  
A blown fuse is indicated by a burnt connector. Pull the fuse  
from the holder when replacing.  
Check the spark plug. Replace the spark plug if the  
electrodes are burned or if the insulation is cracked or  
damaged. Clean the spark plug with a steel brush if it is to  
be reused.  
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.  
4
Measure the electrode gap with a gapping tool. The gap  
should be 0.75 mm/0.030”. Adjust as necessary by  
bending the side electrode.  
Checking the tyre pressure  
5
6
Reinsert the spark plug, turning by hand to avoid  
damaging the threads.  
The tyre pressure should be 60 kPa (0.6 bar / 9 PSI) all round.  
To improve driving the pressure on the rear tyres can be  
reduced to 40 kPa (0.4 bar/5.6 PSI). The maximum tyre  
pressure is 100 kPa (1,0 bar/14 PSI).  
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.  
IMPORTANT INFORMATION  
Inadequately tightened spark plugs can cause overheating  
and damage the engine. Tightening the spark plug too  
much can damage the threads in the cylinder head.  
IMPORTANT INFORMATION  
Do not turn over the engine if the spark plug or ignition cable  
has been removed.  
Different tyre pressures on the front tyres will result in the  
blades cutting the grass at different heights. Having the  
same air pressure in the tyres is important in order to  
achieve the best possible performance as well as to avoid  
damage to the machine  
Check the safety system  
The Rider is equipped with a safety system that requires the  
following conditions.  
The engine can only be started when:  
The cutting deck is raised and the parking brake is  
applied.  
The engine should stop when:  
The cutting deck is lowered and the driver rises from the  
seat.  
The cutting deck is in its raised position, the parking brake  
is not applied and the driver rises from the seat.  
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.

Remove the dipstick. Remove the drain plug from the  
engine’s left side.  
Open the engine cover.  
Loosen the dipstick, pull it up and wipe it off.  
3
4
5
Let the oil run out into the container.  
Fit the drain plug and tighten it.  
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. See Checking the engine’s oil level for  
filling instructions. The engine holds 1.4 litres (1.5 USqt)  
when the oil filter is not replaced and 1.6 litres (1.7 USqt)  
of oil when the oil filter is replaced.  
Now insert the dipstick again. The dipstick should be  
completely screwed down  
Pull the dipstick out again and read the oil level.  
6
Run the engine warm, then check that there is no leakage  
from the oil plug.  
The oil level should be between the markings on the dipstick.  
If the level is approaching the ADD mark, top up the oil to the  
FULL mark on the dipstick.  
IMPORTANT INFORMATION  
Used engine oil, antifreeze etc. 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.  
ADD  
FULL  
Avoid skin contact; wash with soap and water in case of  
spills.  
ADD

Changing the oil filter  
The oil is topped up through the hole the dipstick sits in. Fill  
the oil slowly.  
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.  
Tighten the dipstick correctly before starting the engine. Start  
and run the engine at idling speed for approx. 30 seconds.  
Turn off the motor. Wait 30 seconds and check the oil level. If  
necessary fill so that the oil comes up to the FULL mark on  
the dipstick.  
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.  
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.  
Replacing the engine oil  
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.  
The engine oil should be changed the first time after 8 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.

Lubrication  
Checking the transmission oil level  
General lubrication  
1
Remove the transmission cover. Undo the two screws  
(one on each side) and lift off the transmission cover.  
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.  
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 318 Fill if necessary with engine oil SAE 10W/40  
(class SF–CC).  
Rider 320 AWD Fill if necessary with oil Synthetic 10W/50  
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  
Service  
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.  
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.  
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.  
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.
