During this instruction, the user should be
made aware
– that the utmost care and concentration
are required for working with the
machine.
– that a ride-on mower which is sliding
down a slope cannot be brought under
control by applying the brake.
The main causes for the loss of control
over the ride-on mower include:
– inadequate adhesion of the wheels,
– driving too fast,
– inappropriate braking,
– incorrect use (sport events, etc.),
– inadequate knowledge of the effects
associated with ground conditions,
especially on slopes (see section "For
your safety", "Working on slopes"),
– incorrect attachment of loads and poor
load distribution.
4.3 Transporting the ride-on mower
On account of its own weight, the ride-on
mower can cause severe crush injuries.
Particular care must be taken when
loading or unloading the ride-on mower
onto/from a vehicle or trailer for transport
purposes.
This ride-on mower must not be towed. For
transporting on public roads, a suitable
vehicle or a suitable trailer must be used.
During transport, the ride-on mower must
be secured to a load floor as described in
this instruction manual. Furthermore, the
parking brake must be engaged. (Ö 15.)
Prior to transporting or storage, disengage
the drive to the mowing blades or
attachments.
When transporting the machine, always
observe regional legislation, especially
regarding load security and the transport
of objects on load floors.

4.4 Refilling the tank – handling petrol
Danger to life!
Petrol is poisonous and extremely
inflammable.
Petrol must only be stored in appropriate,
tested containers (canisters). Always
screw on the fuel tank and canister caps
properly and tightly. Defective caps must
be replaced for safety reasons.
Keep petrol away from sparks,
naked flames, pilot lights, heat
sources, and other ignition
sources. Do not smoke!
Refill the tank out-of-doors and do not
smoke during refilling.
Before refilling the tank, stop the engine
and allow it to cool.
Refilling with petrol must be performed
before the engine is started. When the
engine is running or is hot, the tank cap
must not be removed and the tank must
not be refilled with petrol.
Open the fuel tank cap slowly and
carefully. Wait for pressure compensation
and only then remove the tank cap
completely.
Use a suitable funnel or filling pipe for
refilling the tank, so that no fuel can spill
onto the engine and housing or the lawn.
Do not overfill the fuel tank!
To give the fuel room to expand,
never fill the fuel tank past the
lower edge of the filler neck.
Observe the additional
instructions in the engine
instruction manual.
If petrol is spilled, the engine
must only be started after the petrolcontaminated area has been cleaned. All
attempts at starting must be avoided until
the petrol fumes have dispersed (wipe
dry).
Any spilt fuel must be wiped up
immediately.
Clothing must be changed if it comes into
contact with petrol.
Following each refilling of the tank, the fuel
tank cap must be properly screwed on and
tightened. The machine must not be
operated without the original tank cap.
For safety reasons, the fuel line, fuel tank,
tank cap and connections must be
checked regularly for damage, ageing
(brittleness), firm seating and leaks.
Replace if necessary (consult a specialist
dealer; VIKING recommends VIKING
specialist dealers).
If it is necessary to drain the tank, this must
be done out of doors.
Never use beverage bottles or similar for
disposal or storage of fuels and lubricants.
Persons, particularly children, could be
tempted to drink out of them.
Never store the machine with petrol in the
tank inside a building. The resulting petrol
fumes could come into contact with naked
flames or sparks and could be ignited.
Do not leave the machine and the fuel tank
close to heating systems, radiant heaters,
welding equipment and other sources of
heat. Explosive hazard!
4.5 Clothing and equipment
Always wear sturdy footwear
with high-grip soles when
working. Never work barefoot
or, for example, in sandals.
Always wear long trousers and tight-fitting
clothing when operating the machine.
Never wear loose clothes which may
become caught on moving parts (control
levers) – do not wear jewellery, ties or
scarves.
Also always wear sturdy gloves
and tie up and secure long hair
(headscarf, cap, etc.) when
performing maintenance and
cleaning work or when transporting the
machine.
Wear suitable safety glasses
when sharpening the mowing
blades.
4.6 Before operation
Make sure that only persons who are
familiar with the instruction manual are
permitted to use the machine.
Check the fuel system (particularly visible
parts such as e.g. tank, tank cap, hose
connections) before operating the
machine. In the event of any leaks or
damage, do not start the engine – fire
hazard!
Have the machine repaired by a specialist
dealer prior to operation.
Mounting and dismounting the machine
must be performed from the left-hand side
of the machine when the mowing deck is
installed. The deflector flap, which must
never be stood on, is located on the righthand side.
Observe the local regulations regarding
permitted operating times for gardening

Carefully inspect the complete area on
which the machine is to be used and
remove any stones, sticks, wires, bones
and other foreign objects which could be
thrown up by the machine. Obstacles (e.g.
tree stumps, roots) can be easily
overlooked in long grass.
For this reason, mark all foreign objects
(obstacles) which are hidden in the lawn
and cannot be removed before
commencing work with the machine.
Defective and all other worn or damaged
parts must be removed before using the
machine. Replace any illegible or
damaged danger signs and warnings on
the machine. Your VIKING specialist has a
supply of replacement stickers and all the
other spare parts.
Never use the machine with damaged
safety devices or with safety devices
removed.
The screwed-on discharge port (discharge
chute on mowing deck) must always be
securely fastened to the mowing deck. It
must not be damaged and, if necessary, it
must be replaced by a technician.
The braking function must be checked
before each use. (Ö 8.11)
Before each use, check whether:
– the cutting tool and the entire cutting
unit (mowing blade, blade clutch, blade
brake, retaining pin, mowing deck
housing) are in good condition.
Particularly check for secure fastening,
damage and wear.
– the tank cap is securely attached.
– the tank and fuel-carrying parts, as well
as the tank cap are in good condition.
– the safety devices are in good condition
and function correctly.
– the tyres (inflation pressure, damage,
wear) and frame are in good condition.
Check that all screw connections are
securely fastened. In particular, all
maintenance operations listed in the
maintenance schedule under the
heading “Before each use” must be
carried out. (Ö 14.1)
If necessary, consult a specialist dealer.
VIKING recommends VIKING specialist
dealers.
4.7 Working with your machine
Never work in the vicinity of
other persons, particularly
children, or animals. Ensure
that the grass is never
discharged in the direction of other
persons.
Do not operate the machine in the rain or
during thunder storms, particularly when
there is a risk of lightning strike.
Exhaust gases:
Danger to life through poisoning!
In the case of nausea, headache,
impaired vision (e.g. decreasing
field of view) hearing disorder,
dizziness, decreasing power of
concentration, stop working
immediately. These symptoms may
be caused by excessively high
exhaust gas concentrations.
The machine generates
poisonous exhaust gases when
the engine is running. The
gases contain poisonous
carbon monoxide, a colourless and
odourless gas, as well as other pollutants.
The engine must never be operated in
closed or poorly ventilated spaces.
The engine exhaust is released into the air
in a forward direction, between the two
front wheels. When working with the
machine, ensure that this area is always
kept clean and is never covered in order to
prevent the accumulation of exhaust
gasses.
Starting:
The machine must only be started from the
driver's seat.
Start the machine on level ground, not on
a slope.
The engine may only be started in a well
ventilated working area, sufficient
ventilation must be ensured, particularly in
garages.
Before starting the engine, disengage the
cutting tool, attachments and drive and
press down the brake pedal fully.
When starting, it must be ensured that
there is sufficient clearance between the
feet and the cutting tool.
Never start the engine by short-circuiting
the starter terminal. If the normal starter
circuit is bypassed, the ride-on mower may
suddenly be set in motion.
Never start the engine if the smell of petrol
can be detected – Explosive hazard!
10
0478 192 9804 B - EN
Working:
Warning – Risk of injury:
Observe the working
area of the mowing
blade. Never put hands
or feet on or underneath
rotating parts. Never touch the
rotating mowing blades. Always
keep away from the discharge
opening. An adequate safety
distance must always be
maintained.
Only work during the day or with good
artificial light.
When driving off the lawn or when not
mowing, the mowing blades must be
disengaged and the mowing deck must be
set to the highest cutting position.
Objects hidden in the turf (lawn sprinkler
systems, posts, water valves, foundations,
electrical wires, etc.) must be avoided.
Never run over any such foreign objects.
The mowing deck should be removed
when working with additional attachments
– observe instruction manual for the
attachments.
Always hold the steering wheel firmly with
both hands when driving.
Particular care must be taken when driving
on lawns and other uneven surfaces, as
the steering wheel can be made to turn
due to holes, mounds, impacts, etc.
Risk of injury to hands and fingers!
If, during operation, a defect in the tank,
tank cap or in the fuel-carrying
components (fuel lines) is detected, the
engine must be stopped immediately. A
specialist dealer must then be contacted.
VIKING recommends VIKING specialist
dealers.
Beware of depressions (holes) in the
terrain and other invisible points of danger.
Obstacles can be easily overlooked in long
grass.
Always drive at a reasonable speed.
Use the machine with great care when
working near slopes, terraces, ditches and
embankments. In particular, ensure that
you maintain sufficient distance to such
danger areas.
Particular care must be taken at points of
poor visibility, bushes, trees and other
obstacles, behind which persons,
especially children, or animals may be
hidden.
Bring the ride-on mower to a standstill
immediately and stop the mowing blade if
someone moves into the area to be mown.
Always monitor the area in front of the
vehicle. Beware of obstacles, in order to
be able to evade them in time.
Before reversing, always check the area
behind the ride-on mower and, if present,
disengage the attachment. Never mow in
reverse, if it is not absolutely necessary.
When mowing in reverse, take particular
care and before beginning to mow,
thoroughly check the entire area behind
the ride-on mower.
When working together in a group, always
inform the others in advance of what you
intend to do. Maintain a safety distance!
The vehicle speed must be reduced before
each change of direction, so that the user
retains control of the machine at all times
and also that the ride-on mower cannot tip
over.
When operating near to roads and when
crossing roads, other road users must be
taken into account.
Take particular care when mowing near
roads, cycle paths and footpaths. Objects
which are thrown up by the mower can
cause severe injury and damage.
When operating the ride-on mower with
attachments, always follow the
instructions and safety regulations
supplied with the attachments.
Switch off the drive, stop the engine and
wait until the mowing blades have come to
a complete standstill, engage the parking
brake and remove the ignition key:
– before removing blockages.
– before checking, cleaning or working on
the ride-on mower,
– if a mowing blade has hit an obstacle.
Inspect the machine and the cutting tool
for damage and have any necessary
repairs performed before re-starting.
– if the machine begins to vibrate
excessively. It must be checked
immediately.
– when abandoning or when transporting
the machine.
Stop the engine and wait until the mowing
blades have come to a complete standstill:
– Before filling with fuel.
Working on slopes:
Slopes are one of the major causes of
accidents in which control over the ride-on
mower is lost causing it to tip over, which
can result in severe or even fatal injuries.
There is no "safe" slope! Driving on grassy
slopes requires special concentration.
For safety reasons, the machine must not
be used on slopes with an inclination of
more than 10° (17.6 %). Risk of injury!
ENNO
SVFIDAPL
0478 192 9804 B - EN
11
A slope inclination of 10° corresponds to a
vertical height increase of 17.6 cm for a
100 cm horizontal distance.
In order to ensure an adequate oil supply
for the engine, the information in the
accompanying engine instruction manual
must be additionally observed when using
the machine on slopes.
If you cannot drive up the slope in reverse
or if you have doubts regarding safety, you
should not drive on the slope.
Starting off or stopping on a gradient must
be avoided.
Do not use the machine in places (slopes,
ditches, etc.) where the ride-on mower can
tip over or slide. The danger of tipping over
or sliding increases if the ground is soft or
damp.
Slopes must be driven on in a longitudinal
direction. Driving transversely increases
the danger of tipping over.
Do not change speed or direction abruptly
when driving on slopes. Work in this type
of situation requires calm, cautious and
even operation of the ride-on mower.
Changes of direction on slopes must be
avoided. Only turn on slopes if this is
unavoidable. If possible, drive slowly and
in a large curve in the down-slope
direction.
Do not mow wet grass, particularly on
slopes, as wheel grip is reduced on wet
grass. The ride-on mower could slide and
become uncontrollable for the user.
The gearbox must never be disengaged
via the gearbox freewheel when driving on
slopes.
Special care must be taken when
operating attachments on slopes (altered
weight distribution of the machine).
Never try to stabilise the ride-on mower by
pressing on the ground with your foot.
If the wheels should start to slip or if the
vehicle becomes stuck in the up-slope
direction when driving on an incline, the
mowing blades or the attachment must be
disengaged. Then leave the slope by
driving slowly downhill in a straight line.
Pulling loads:
Particular care must be taken when pulling
loads, in order to prevent the risk of severe
or even fatal injuries due to the ride-on
mower tipping over.
Only use accessories approved by VIKING
for transporting objects. Transportation on
the ride-on mower is not permitted.
For pulling loads, use only the trailer hitch.
Loads must never be attached to the axle
housing or to another point above the
trailer hitch.
Please refer to the section "Pulling loads"
for information on pulled and coupling
loads. (Ö 12.8)
Exceeding the specified pulled load is
dangerous and may result in damage to
the machine (engine, gearbox, etc.).
When transporting on slopes, the loads
must be adapted so that safe handling of
the ride-on mower (e.g. braking, change of
direction, starting off) is ensured at all
times.
Check whether loads are properly and
securely fastened. Use lashing straps for
securing loads.
Ensure balanced load distribution.
Use suitable additional weights
(accessories) if this is described in the
instruction manual for the attachment.
Do not execute tight curves. Particular
care must be taken when reversing.
Do not change speed or direction abruptly.
Stopping and parking:
The ride-on mower must only be parked on
a level surface.
Make sure that the ride-on mower has
come to a complete standstill before you
dismount.
Beware of the cutting tool
running on for several seconds
before coming to a standstill.
Before leaving the driver’s seat,
disengage the mowing blades
or the drive to the attachments, lower the
mowing deck and all attachments, set all
control levers to the neutral position,
engage the parking brake, stop the engine
and remove the ignition key.
Keep the ignition key in a place where only
authorised persons can access it.
12
0478 192 9804 B - EN
4.8 Maintenance and repairs
Before beginning cleaning,
adjustment, repair and
maintenance operations, park
the machine on firm, level ground, engage
the parking brake, stop the engine, allow it
to cool down and remove the ignition key.
Be aware that moving one cutting tool
results in the turning of the other cutting
tools.
Allow the machine to cool down before
working on or around the engine, exhaust
manifold or muffler; this also applies in
particular to all maintenance operations on
the mowing deck. Temperatures of 80 °C
and above can be reached. Danger of
burns:
Cleaning:
Following operation, the entire ride-on
mower and the attachments must be
cleaned. In particular, all grass residues
must be removed because the moisture
these contain leads to damage in the long
term.
VIKING does not recommend the use of
high pressure cleaners. (Ö 14.2)
Remove the mowing deck for cleaning
operations. Never clean the mowing deck
using water under high pressure (e.g.
garden hose) or by engaging the mowing
deck in puddles of water.
Never drive close to an edge or a ditch for
the purpose of cleaning (e.g. the frame of)
the ride-on mower.
In order to prevent fire hazards, keep the
engine, cooling ribs, battery compartment,
area around the fuel tank and exhaust free
from grass, leaves or escaping oil (or
grease).
Maintenance operations:
Only maintenance operations described in
this instruction manual may be carried out.

● Turn the ignition key to the "engine off"
position. (Ö 8.1)
● Check the polarity of the battery
connections and connect the wiring
correctly if necessary. (Ö 14.18)
● Repeat self-diagnosis.
If the continuous beep continues to
sound even after the battery is correctly
connected, an electronic fault is
present. Consult a specialist dealer;
VIKING recommends VIKING specialist
dealers.
Three successive beeps signal a fault in
the electrics (short circuit) or in the seat
switch. It is not possible to start the engine.
● Turn the ignition key to the "engine off"
position. (Ö 8.1)
● Have a detailed diagnosis carried out
by a specialist dealer. VIKING

10. Notes on working with the machine
Warning:
Risk of injury.
Before each use, observe all
information regarding safe
operation of the machine.
Working on slopes requires special
concentration and care.
Note
Check the mowing deck for correct
installation position before starting
work.
Select a flat, even area for initial
use of your machine and mow in
straight and slightly overlapping
strips for practising purposes.
Grass should always be mowed
when dry.
10.1 Mowing operation General information:
Caution - fire hazard!
Avoid overloading the mowing deck
drive. Overloading may lead to
constant slipping of the V-belt and
consequently to a fire hazard due to
overheating.
Unusual running noise, e.g. a
"squealing" (slipping noise) of the
V-belt, indicates overloading.
For this reason, never mow in high
grass when the discharge chute is
blocked; use a mulching kit (special
accessory) if necessary.
The mowing deck, particularly the
V-belt area, must always be kept
free of combustible material (grass,
leaves, etc.). It should also be
cleaned regularly to prevent a fire
hazard.
During the mowing operation, the clippings
are ejected over a wide area to the side of
the mowing deck, where they remain on
the ground.
The following points must be observed so
that the clippings are ejected over a wide
area:
● Take account of the driving direction.
● Only mow at the maximum engine
speed. (Ö 8.2), (Ö 8.3)
● The lawn should be dry. Owing to their
higher weight, wet clippings lead to the
formation of swathes.
● The mowing blades must be in proper
condition (sharp, undamaged).
(Ö 14.6)
● Adjust the driving speed to the condition
of the lawn. (Ö 8.10)
● Select an appropriate cutting level – do
not mow too low. (Ö 12.6)
Driving direction when mowing:
During the mowing operation, an
appropriate driving direction must be
observed.
Always select the mowing direction so that
the clippings are ejected onto the already
mown lawn area. This ensures that the
clippings are ejected and distributed
evenly. Moreover, overloading of the
machine owing to excessive quantities of
grass is prevented.
Example:
Mowing in spiral pattern
The mowing operation is performed
anti-clockwise, from the outside
inwards. This ensures that the
clippings are ejected onto the
already mown lawn area.
● Begin from the outer edge of the lawn
and work you way inwards.
● Select an anti-clockwise driving
direction.
ENNO
SVFIDAPL
0478 192 9804 B - EN
23
Preventing blockage of the mowing
deck / of the discharge opening:
In order to prevent blockage of the mowing
deck discharge opening, it should be
regularly checked visually during mowing
and cleaned if necessary.
If the mowing deck discharge opening
frequently becomes blocked with grass,
reduce the driving speed or select a higher
cutting level.
If the problem persists, the probable cause
is blunt mowing blades or damaged or
worn wings on the mowing blades.
Sharpen or replace the mowing blades.
Furthermore, the inside of the mowing
deck, the mowing deck discharge opening
and the mowing blades should be carefully
cleaned after each use to prevent the
accumulation of grass deposits.
Fertilising:
Mowing the grass deprives the ground of
permanent nutrients, which can be
returned by using a high-grade, long-term
lawn fertiliser. Usually, fertilising three
times per mowing season is necessary.
For this purpose, the lawn should be dry,
so that the fertiliser does not stick to the
grass blades and burns them. It is then
better to water the lawn, which results in
the fertiliser being flushed off the grass
blades. (observe manufacturer's
instructions for use.)
Ground-conserving working:
The most important factors for groundconserving working are operating
technique and ground moisture.
In order to achieve clean mowing results,
the driving speed must be adapted to the
condition of the grass to be mowed (to the
height and density) and to the moisture of
the lawn.
Executing curves that are too tight
increases the loading on the turf and leads
to poor mowing results, particularly on wet
grass, as the wheels sink into the soft
grass.
11. Safety devices
The machine is equipped with several
safety devices for safe operation and for
the prevention of improper use.
Risk of injury!
If a safety device is found to be
defective, the machine must not be
operated. Consult a specialist
dealer; VIKING recommends
VIKING specialist dealers.
To start the engine, the following
conditions must always be fulfilled:
– the mowing deck must be disengaged,
– the brake pedal must be pressed or the
parking brake engaged.
The engine stops if the user:
– leaves the driver’s seat with the mowing
deck engaged,
– leaves the driver's seat without
engaging the parking brake.
Integrated blade run-down brake:
Following disengagement, the mowing
blades come to a standstill after
5 seconds at the latest.
Note
Following engagement of the
mowing deck, the mowing blades
turn and a wind noise is audible.
The run-on time corresponds to the
duration of the wind noise following
disengagement. This can be
measured using a stopwatch.
12. Operating the machine
● Carefully read and observe the section
entitled "For your safety". (Ö 4.)
● Ensure that you are familiar with the
controls of the machine. (Ö 8.)
● Before operating the machine, inspect
the maintenance schedule and carry
out all relevant maintenance
instructions. (Ö 14.1)
● Before each use, check that all safety
devices are operating correctly.
No safety devices must be missing,
overridden, modified or damaged.
(Ö 11.)
Risk of injury:
For safety reasons, the machine
must not be used on slopes with an
inclination of more than 10°
(17.6 %).
A slope inclination of 17.6 %
corresponds to a vertical height
increase of 17.6 cm for a 100 cm
horizontal distance.
12.1 Filling the fuel tank
Maximum tank capacity:
9litres
Recommendation:
Fresh good quality fuel, please
refer to the engine instruction manual for
information on fuel grade (octane rating).
– Unleaded petrol.
Filling procedure:
● Stop the engine and allow it to cool
down (warm to the touch). (Ö 12.3)
● Engage the parking brake. (Ö 8.12)
24
0478 192 9804 B - EN
To prevent fuel spillage, use a
suitable funnel (not included in
standard equipment) when filling
up.
Pour in the fuel slowly and carefully. In
order to prevent the fuel from overflowing,
filling should be performed in several
stages.
Remove the funnel between the individual
filling operations in order to visually check
the filling level in the tank.
The more fuel has already been filled into
the tank, the smaller the filling quantities
should be for each filling operation. To give
the fuel room to expand, never fill the fuel
tank past the lower edge of the filler neck.
Tank cap:
Unscrew the tank cap (1) (note direction of
arrow) and remove.
● Fill the fuel into the tank using a suitable
funnel (not included in standard
equipment) (see Filling procedure).
Fit and screw on the tank cap (1) (note
direction of arrow). Then tighten the tank
cap (1) hand-tight.
● Wipe away any spilled fuel and allow it
to evaporate before starting the engine.
12.2 Starting the engine
Risk of injury:
Before starting, carefully read and
observe the section "For your
safety". (Ö 4.)
Only start the machine when the
user is sitting on the driver's seat.
When operating (e.g. mowing), the
throttle lever should always be in

● Lock the cutting height adjustment
lever. (Ö 8.13)
Cutting level 1:
Cutting height 35 mm
Cutting level 7:
Cutting height 90 mm
12.7 Mowing
If the mowing deck is engaged
when driving, the engine speed is
briefly reduced due to the additional
load (mowing blades starting to
rotate).
Before mowing:
● Read and observe the section "Notes
on working with the machine". (Ö 10.)
● Always set the maximum engine speed
during mowing. The mowing blades are
optimised for this speed – it produces
the best cutting pattern as well as the
best cutting performance.
Engage the mowing deck in the
following sequence:
● Start the engine. (Ö 12.2)
● Set the throttle lever to the MAX
position. (Ö 8.2), (Ö 8.3)
● Drive the ride-on mower onto the lawn.
Do not engage the mowing deck in tall
grass or when set to the lowest cutting
level. Only engage the mowing deck
when the machine is already on the
area to be worked.
● Forward mowing:
Select the forward driving direction
(Ö 8.7), then engage the mowing deck
by pressing the mowing deck switch.
(Ö 8.5)
Reverse mowing:
Select the reverse driving direction
(Ö 8.7) and briefly press the reverse
mowing safety switch (Ö 8.6) once,
then engage the mowing deck by
pressing the mowing deck switch within
6 seconds. (Ö 8.5)
During mowing:
● Set the throttle lever to the MAX
position. (Ö 8.2), (Ö 8.3)
● Always adapt the driving speed to the
grass height/cutting level.
A low driving speed should be selected
when mowing tall grass/at a low cutting
level.
Changing the driving direction with the
mowing deck engaged:
● For reverse mowing, briefly press the
reverse mowing safety switch once
within the designated time window
(5 seconds/1 second after switching).
(Ö 8.6)
● Bring the machine to a standstill on the
lawn and set the required driving
direction using the driving direction
selector lever. (Ö 8.7)
● Continue mowing.
Disengage the mowing blade in the
following sequence:
● Drive onto an area of grass which has
already been mown or select the
highest mowing deck cutting level.
(Ö 8.13)
● Disengage the mowing deck by
pressing the mowing deck switch.
(Ö 8.5)
Risk of injury!

12.8 Pulling loads Risk of injury:
Before attaching loads, always
check the braking function. (Ö 8.11)
The driving characteristics of the
machine are changed when
transporting loads (longer braking
distances, select lower driving
speed when changing direction,
etc.). The heavier the load, the
more the driving characteristics are
changed.
Avoid damage to the machine.
The maximum pulled load is
decreased on inclines.
Maximum trailer weight on a level
surface = 250 kg
Maximum trailer weight on a maximum 10°
inclination = 100 kg
Maximum coupling load = 40 kg
Maximum pulled load = 40 kg
A pulled load of 40 kg at the trailer
coupling is achieved when pulling a
trailer with a weight of 250 kg on a
level surface.
12.9 Operating on slopes
● Check the braking function before
operating the mower on slopes.
(Ö 12.5)
● Drive slopes in a longitudinal direction.
Driving transversely increases the
danger of tipping over – note the
maximum slope inclination. (Ö 4.7)
● Avoid changes of direction on slopes –
if changes of direction cannot be
avoided, they must be executed with
particular care.
13. Mowing deck
