INTRODUCTION
Introduction
Congratulations
Thank you for purchasing a Husqvarna ride-on mower. This machine is built for the greatest efficiency and
rapid mowing primarily of large areas. Controls in one place and a hydrostatic transmission regulated by
steering controls also contribute to the machine’s 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 operator’s manual to the new owner.
The final chapter of this operator’s 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 machine’s resale value. Take the operator’s manual along when the machine is left to the
workshop for service.
General
In this operator’s manual, left and right, backward and forward are used in relation to the machine’s normal
driving direction.
Driving and Transport on Public Roads
Check applicable road traffic regulations before driving and transport on public roads. If the machine is
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 manufacturer’s 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
machine’s special characteristics and who are well versed in the safety instructions.
Accident prevention regulations, other general safety regulations, occupational safety rules, and traffic
regulations must be followed without fail.
Unauthorized modifications to the design of the machine may absolve the manufacturer from liability for any
resulting personal injury or property damage.

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
machine’s stability.
Be extra cautious when driving on slopes
•
•

Steering Controls
The machine’s 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 fit in
the slots for moving the controls outward,
they can be adjusted using the adjustment
screws, not the link system, for the controls.

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 fixed
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 finest 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

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 specified 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 refit 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 flames, sparks, or a pilot
light such as in a boiler, hot
water tank, clothes drier, etc.
Handle the fuel with care. It is
very flammable and careless
use can cause serious personal
injury and property damage.
Drain the fuel into an approved
container outdoors and far
away from open flame. 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.
