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  
This is what you do  
use of the machine to use or service it. Local laws may  
regulate the age of the user.  
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°.  
!
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.  
Use hearing protection to minimise the risk of hearing  
impairment.  
Avoid unnecessary turns on slopes, if necessary, turn  
slowly and gradually downwards if possible. Drive slowly.  
Do not turn the wheel sharply. Rider 11: Select a low gear  
so that you will not need to stop to change gear. The  
machine engine-brakes even better in low gear.  
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.  
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.  
Driving on slopes  
Do not try to stabilize the machine by putting your foot on  
the ground.  
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 cleaning the chassis, the machine may never be  
driven near verges or ditches.  
IMPORTANT INFORMATION  
Do not drive down slopes with the unit raised.

and down for small children.  
Store the machine and fuel in such a way that there is no  
risk that leaking fuel or fumes can cause any damage.  
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.  
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.

lead pollutants, chemicals that are  
considered to cause cancer, birth defects or  
other reproductive impairment. Wash your  
hands after touching the battery.  
!
Be particularly careful near corners, bushes, trees or  
other objects that block your view.  
Be especially careful when handling battery acid. Acid on  
the skin can cause serious corrosive injuries. In the event  
of spillage on the skin wash immediately with water.  
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.

engage reverse gear.  
- Gears 1-4 are used for mowing  
- Gears 4-5 are used for transporting  
WARNING! Clear the lawn from stones and  
other objects which can be thrown out by  
the blades.  
Starting can take place independent of which gear is  
engaged.

not be made while the machine is moving.  
collision.  
Start with a high cutting height and reduce down until the  
required mowing results are obtained.  
The engine must be disengaged during each gear change.  
Stop the machine before changing between forward and  
reverse gears, otherwise this may result in damage to the  
gearbox.  
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.  
Never use force to engage a gear.If a gear does not engage  
immediately, release the clutch pedal and press it down  
again. Now try to engage the gear again.

For Rider 11 C Pull back the throttle and move the gear  
shift lever to the neutral position ”N”, without pressing in  
the reversing lock button. Turn the ignition key to the  
”STOP”.  
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.  
For Rider 13 C, Rider 16 AWD and Rider 16 C Pull back

Storage  
Always use genuine parts.  
Winter storage  
Annual inspection or tuning by an authorised service  
workshop is a good way of getting the best out of your  
machine the next season.  
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.  
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.  
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
4
Change the engine oil, and take care of the waste oil.  
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
7
Grease all grease nipples, joints and axles.  
Remove the battery. Clean it, charge it, and store it in a  
cool place.  
8
Store the machine in a clean and dry place and cover it  
over for extra protection.  
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.
