when driving.
Safety Instructions
• 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.
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.
16
WARNING:
Do not drive down slopes with the unit raised.
Control can be reduced due to the changed centre of
gravity.
Do as follows
• Remove obstacles such as stones, tree branches, etc.
• Mow up and down, not side-to-side.
Mow upwards and downwards on slopes, not sideways.
• The differential lock should also be used on
Be extra cautious when driving on slopes
slopes.
• Never drive the machine on terrain 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 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. It is easier for the machine to
overturn on uneven ground. Tall grass can hide
obstacles.
• Drive slowly. Do not turn the wheel sharply.
• Be extra cautious with any additional equipment,
which can alter the machine’s stability.
• Do not mow near verges, 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.
17
Safety Instructions
Safety Instructions
• Try not to stabilise the machine by putting a foot on
the ground.
• When cleaning under the machine, it may never be
driven near verges or ditches.
Children
• Serious accidents may occur if you fail to be on
guard for children in the vicinity of the machine.
Children are often attracted to the machine and
mowing. Never assume that children will stay put
where you last saw them.
• Keep children away from the mowing area 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 a reversing manoeuvre, look
backward and downward for small children.
• Never allow a child to ride with you. They can fall
off and seriously injure themselves or be in the
way for safe manoeuvring of the machine.
• Never allow children to operate the machine.
• Be particularly careful near corners, bushes, trees
or other objects that block your view.

21
Safety Instructions
• Sparking can occur when working with the battery
and the thick cables in the starter motor circuit.
This can cause the battery to explode, fire or eye
injuries.
Sparking in the circuit can not occur once the
battery's power connection cable (usually the
black negative cable) has been disconnected.
Safety Instructions
IMPORTANT INFORMATION:
Avoid sparking and its consequences by:
Wearing protective glasses.
Make sure that the fuel cap is fitted and that no
flammable liquids are stored in an open container.
Do not work on the starter motor circuit in the vicinity of
spilt fuel.
Disconnect the battery's power connection cable (usually
the black negative cable) first and connect it last.
Exercise care with tools so that short circuiting does
not occur.
Do not short circuit across the starter relay's
connections to run the starter motor.
• 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.
22

Safety Instructions
Transport
IMPORTANT INFORMATION:
The parking brake is not sufficient to lock the
machine during transport. Ensure you secure the
machine firmly to the transporting vehicle.
The machine is heavy and can cause serious crushing
injuries. Be extra cautious when it is loaded on or
unloaded from a vehicle or trailer.
• Use an approved trailer to transport the machine.
Activate the parking brake and secure the machine
using approved fasteners, such as straps, chains
or ropes when transporting.
• Check and comply with laws and regulations when
driving on public roads, a traffic kit is available as
an option. This can be retrofitted on PT 26D.
Safety Instructions
Environment protection
Take care of the environment, there are numerous
environmental risks especially when performing
maintenance on the machine. This particularly applies
when dealing with engine oil, hydraulic oil, fuel, oil
filters, hydraulic filters and fuel filters. You must be
attentive to ensure spillage does not occur when you
open a system that contains oil or fuel.
• Always wipe up spillage. When using cloths,
sawdust or oil absorbents, these should be treated
as environmental hazardous waste. Follow local
regulations.
• Choose an area, preferably with a concrete floor,
when you handle or store oils and fuel so that you
can clear up any spillage without it penetrating into
the ground.
• Avoid spillage, use a funnel and fill carefully.
• When draining, ensure that a suitably sized
container is placed correctly. Remember that the
oil does not always run straight down.
• Transfer the waste oil into a sealed container and
hand in for destruction. Remember to follow local
regulations. Generally you can deposit waste oil at
workshops or petrol stations that handle waste oil.
26
• Replaced oil and fuel filters are environmental
hazardous waste, handle them as waste oil.
• Do not spill fuel when refuelling. One litre of diesel
fuel can, according to the Swedish Rescue
Services Agency, destroy up to one million litres of
drinking water. Spilt fuel is a fire risk.
• Wash your hands thoroughly when the job is done.
• Coolant is poisonous and sweet. Ensure that
animals do not come into contact with open
containers or pools of fluid.
• Bear in mind the risk of grass fire when working in
dry vegetation. Never operate a machine with a
modified or damaged muffler, as sparks from the
exhaust fumes can set dry grass on fire.

Presentation
Chapter 4: Presentation
Congratulations on your choice of an exceptionally
high quality product. This operator's manual describes
Husqvarna PT 26D.
It is fitted with a Perkins 3 cylinder diesel engine
developing 26 horse power.
PT 26D is equipped with hydraulic steering and
attachment lift. They are supplied with pressure from a
pump on the engine.
The machine is all wheel drive in low speed mode.
The power transmission from the engine is hydrostatic.
It is supplied with pressure by a pump under the
driver’s seat. A shaft with two flexible couplings
powers the pump. Flow and direction are regulated
with the pedals, so that forward and reversing speeds
are variably controlled. One pedal to drive forwards (1)
and one pedal to reverse (2). The pump drives four
hydraulic motors in parallel, one for each wheel.
The power transmission is also used as service brake.
There are low and high speeds for driving. High or low
speed is selected using a switch.
