INTRODUCTION  
Introduction  
Congratulations  
Thank you for purchasing a Husqvarna ride-on mower. This machine is built for the greatest efciency and  
rapid mowing primarily of large areas. Controls in one place and a hydrostatic transmission regulated by  
steering controls also contribute to the machines performance.  
This manual is a valuable document. Following the instructions (use, service, maintenance, etc.)  
can considerably increase the lifespan of your machine and even increase its resale value.  
If you sell your machine, be sure to give the operators manual to the new owner.  
The nal chapter of this operators 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 machines resale value. Take the operators manual along when the machine is left to the  
workshop for service.  
General  
In this operators manual, left and right, backward and forward are used in relation to the machines normal  
driving direction.  
Driving and Transport on Public Roads

transported, you shall always use approved fastening equipment and ensure that the machine is well  
anchored.  
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.  
Operating  
This machine is constructed only for mowing grass on lawns and other free and even ground without  
obstacles such as stones, tree stubs, etc. The machine can also be used for other tasks when equipped  
with special accessories provided by the manufacturer, for which the operating instructions are provided in  
conjunction with delivery. All other types of use are incorrect. The manufacturers directions concerning  
operation, maintenance, and repairs must be carefully followed.  
The machine must only be operated, maintained, and repaired by persons that are familiar with the  
machines special characteristics and who are well versed in the safety instructions.

SAFETY INSTRUCTIONS  
Driving on Slopes  
Driving on slopes is one of the operations  
where the risk is greatest that the driver will  
lose control or the machine will tip over, which  
can result in serious injury or death. All  
slopes require extra caution. If you cannot  
reverse up a slope or if you feel unsure,  
do not mow the slope.  
Do as follows  
Remove obstacles such as stones,  
tree branches, etc.  
Mow up and down, not side-to-side.  
Never drive the rider on terrain that  
slopes more than 15°.  
6003-004  
Avoid starting or stopping on a slope. If  
the tires begin to slip, shut down the  
blades and drive slowly down the slope.  
Mow up and down, not side-to-side  
Always drive evenly and slowly on  
slopes.  
Make no sudden changes in speed or  
direction.  
Avoid unnecessary turns on slopes, and  
if it proves necessary, turn slowly and  
gradually downward, if possible.  
Watch out for and avoid driving over  
furrows, holes, and bumps. On uneven  
terrain, the machine can tip more easily.  
Long grass can hide obstacles.  
Drive slowly. Use small movements of  
the steering controls.  
8011-519  
Be extra cautious with any additional  
equipment, which can alter the  
machines stability.  
Be extra cautious when driving on slopes  
Do not mow near verges, ditches, or  
banks. The machine can suddenly spin  
around if a wheel goes over the edge of a  
drop or ditch, or if an edge gives way.  
Do not mow wet grass. It is slippery, and  
the tires can lose their grip, so that the  
machine slides.  
Try not to stabilize the machine by  
putting a foot on the ground.  
When cleaning the chassis, the machine  
may never be driven near verges or  
ditches.

edge of the seat is moved to the left (as seen  
by the driver in the seat), after which the seat  
can be moved backward or forward.  
8011-562  
Lengthways adjustment  
Steering Controls  
The machines speed and direction are  
continuously variable using the two steering  
controls. The steering controls can be moved  
forward or backward about a neutral position.  
Furthermore, there is a neutral position,  
which is locked if the steering controls are  
moved outward.  
When both controls are in the neutral position  
(N), the machine stands still.  
By moving both controls an equal amount  
forward or backward, the machine moves in a  
straight line forward or backward respectively.  
8011-522  
In order, for example, to turn right while moving  
forward, move the right control towards the  
neutral position.The rotation of the right wheel  
is reduced and the machine turns to the right.  
Steering controls  
Turning on the spot can be achieved by  
moving one control backward (behind the  
neutral position) and carefully moving the  
other steering control forward from its neutral  
position. The rotation direction when turning  
on the spot is determined by which steering  
control is moved backward behind the neutral  
position. If the left steering control is pulled  
backward, the machine turns to the left.  
WARNING!  
The machine can turn very  
rapidly if one steering control  
is moved much further forward  
than the other.  
If the steering controls are in uneven  
positions when standing still or do not t in  
the slots for moving the controls outward,  
they can be adjusted using the adjustment  
screws, not the link system, for the controls.

Ensure that no one is near the  
machine when engaging the  
mower deck.  
5. Engage the mower deck by pulling out  
the lever.  
6. The machines speed and direction are  
continuously variable using the two  
steering controls.When both controls are  
in the neutral position, the machine  
stands still.  
By moving both controls an equal  
amount forward or backward, the  
machine moves in a straight line forward  
or backward respectively.  
8011-510  
In order, for example, to turn right while  
moving forward, move the right control  
towards the neutral position.The rotation  
of the right wheel is reduced and the  
machine turns to the right.  
Engaging the mower deck  
Turning on the spot can be achieved by  
moving one control backward (behind the  
neutral position) and carefully moving the  
other steering control forward from its  
neutral position.

Mowing Tips  
WARNING!  
Clear the lawn of stones and  
other objects that can be  
thrown out by the blades.  
Localise and mark rocks and other xed  
objects in order to avoid collisions.  
Begin with a high cutting height and  
reduce it until the desired mowing result  
is attained.  
The mowing result will be best with a  
high engine speed (the blades rotate  
rapidly) and low speed (the rider moves  
slowly). If the grass is not too long and  
dense, the driving speed can be  
increased without noticeably  
depreciating the mowing result.  
The nest lawns are obtained by mowing  
often. The mowing becomes more even  
and the grass clippings more evenly  
distributed over the mown area.The total  
time taken is not increased as a higher  
driving speed can be used without  
poorer mowing results.  
8011-603  
Mowing patterns  
Avoid mowing wet lawns. The mowing  
result is poorer because the wheels sink  
into the soft lawn, clumps build, and the  
grass clippings fasten under the cowling.  
Hose beneath the mower deck with water  
after each use. When cleaning, the  
mower deck shall be raised into the  
transport position.  
When the BioClip deck is used, it is extra  
important that the mowing interval is not  
too long.  
WARNING!  
Never drive the rider on terrain  
that slopes more than 15°.  
Mow slopes up and down,  
never side-to-side. Avoid  
sudden directional changes.

STORAGE  
To ready the machine for storage, follow these  
steps:  
Storage  
1. Thoroughly clean the machine, especially  
under the mower deck. Touch up damage to  
the paint and spray a thin layer of oil on the  
underside of the mower deck in order to avoid  
corrosion.  
Winter Storage  
At the end of the mowing season, the machine  
should be readied for storage (or if it will not be in  
use for longer than 30 days). Fuel allowed to  
stand for long periods of time (30 days or more)  
can leave sticky residues that can plug the  
carburetor and disrupt engine function.  
2. Inspect the machine for worn or damaged  
parts and tighten any nuts or screws that may  
have become loose.  
Fuel stabilizers are an acceptable option as  
regards sticky residues during storage. If alkylate  
gasoline (Aspen) is used, stabilizers are  
3. Change the engine oil; dispose of properly.  
4. Empty the fuel tanks or add a fuel stabilizer.  
Start the engine and allow it to run until even  
the carburetor is drained of fuel or the  
unnecessary because this fuel is stable. However,  
you should avoid switching between regular and  
alkylate gasoline as sensitive rubber components  
can harden. Add stabilizer to the fuel in the tank or  
in the storage container. Always use the mixing  
ratios specied by the manufacturer of the  
stabilizer. Run the engine for at least 10 minutes  
after adding the stabilizer so that it reaches the  
carburetor. Do not empty the fuel tank and the  
carburetor if you have added stabilizer.  
stabilizer has reached the carburetor.  
5. Remove the spark plugs and pour about a  
tablespoon of engine oil into each cylinder.  
Turn over the engine so that the oil is evenly  
distributed and then ret the spark plugs.  
6. Lubricate all grease nipples, joints, and axles.  
7. Remove the battery. Clean, charge, and store  
the battery in a cool place, but protect it from  
direct cold.  
WARNING!  
8. Store the machine in a clean, dry place and  
cover it for extra protection.  
Never store an engine with fuel  
in the tank indoors or in poorly  
ventilated spaces where fuel  
vapor can come in contact with  
open ames, sparks, or a pilot  
light such as in a boiler, hot  
water tank, clothes drier, etc.  
Handle the fuel with care. It is  
very ammable and careless  
use can cause serious personal  
injury and property damage.  
Drain the fuel into an approved  
container outdoors and far  
away from open ame. Never  
use gasoline for cleaning. Use  
a degreaser and warm water  
instead.  
Service  
When ordering spare parts, please specify the  
purchase year, model, type, and serial number.  
Always use genuine Husqvarna spare parts.  
An annual check-up at an authorized service  
workshop is a good way to ensure that your  
machine performs its best the following season.
