6.16 MÄHWERK
6.16.1 Sicherheit
Um Unfälle bei Kollisionen zu vermeiden und 
wichtige Mähwerkskomponenten zu schützen, ist 
das Gerät mit einer Leistungsbegrenzung versehen 
(siehe unten).
 Brechbolzen zwischen Messern und Messerbal-
ken.
 Drehzahlbegrenzung zwischen Zahnrad und  Messerwelle.
 Möglichkeit für den Zahnriemen, vom Kunstst- offzahnrad zu rutschen.
6.16.2 Demontage
Bei bestimmten Wartungsarbeiten ist es am ein-
fachsten, wenn das Mähwerk vom Gerät abgenom-
men wird. Demontieren Sie das Mähwerk wie 
folgt:
1. Stellen Sie die maximale Schnitthöhe ein.
2. Ziehen Sie die Spannrolle (21:H) heraus und  führen Sie den Riemen (21:J) seitlich nach unt-
en um die Spannrolle, um die Riemenspannung 
zu lockern.
3. Ziehen Sie den Riemen von der Riemenscheibe  ab.
4. Heben Sie das Mähwerk an und lösen Sie die  Verbindung zur Feder des Hubseilzugs (22:K).

6.16.3 Montage
Montieren Sie das Mähwerk wie folgt:
1. Setzen Sie das Mähwerk auf die Vorderachsen. Siehe Abb. 24.
2. Montieren Sie auf beiden Seiten die  Sicherungsschrauben (23:L).
3. Stellen Sie die maximale Schnitthöhe ein.
4. Heben Sie das Mähwerk an und hängen Sie den  Hubseilzug (22:K) ein.
5. Legen Sie den Riemen (21:J) um die Riemen- scheibe.
6. Ziehen Sie die Spannrolle (21:H) heraus und  führen Sie sie um die Außenseite des Riemens, 
um diesen zu spannen.
6.16.4 Messerwechsel Tragen Sie beim Wechseln von Messern 
bzw. Klingen Schutzhandschuhe, um 
Schnittverletzungen auszuschließen.
Achten Sie stets darauf, dass die Messer scharf 
sind. So erzielen Sie optimale Mähergebnisse. Die 
Messer sind einmal pro Jahr zu wechseln.
Kontrollieren Sie nach einer Kollision stets den 
Zustand der Messer bzw. Klingen. Bei einer Be-
schädigung des Messersystems sind defekte Teile 
auszutauschen.
Verwenden Sie ausschließlich Original-
ersatzteile. Die Verwendung anderer 
Ersatzteile ist mit Risiken verbunden, 
auch wenn die Teile zum Gerät passen.
Die Messer sind austauschbar. Um ein gleich-
mäßiges Mähen zu gewährleisten, sind beide Klin-
gen am selben Messerbalken stets gleichzeitig zu 
wechseln.
Achtung!
Beachten Sie bei der Montage Folgendes:
 Messer und Messerbalken sind wie auf Abb. 25  zu montieren.
 Die Messer können in ihren Befestigungen um  120° gedreht werden. Richten Sie die Messer so 
aus, dass sie um 90° zueinander versetzt sind. 
Siehe “6.16.5” unten.
Anzugsdrehmoment: 
Schrauben (25:P) – 45 Nm
Brechbolzen (25:Q) – 9,8 Nm
Bei einer Kollision können die Brechbolzen 
(18:Q) abbrechen und die Klingen ausweichen. 
Montieren Sie in diesem Fall Original-Brech-
bolzen und ziehen Sie sie wie oben beschrieben 
fest. 6.16.5 Synchroni
sierung, Messer
Das Mähwerk besitzt synchronisierte Messer.
Wenn eines der Messer auf einen festen Gegen-
stand stößt (z.B. auf einen Stein), kann sich die 
Synchronisierung ändern. Dadurch besteht die Ge-
fahr, dass die Messer aufeinandertreffen.
Korrekt synchronisierte Messer müssen um 90° 
zueinander versetzt sein. Siehe Abb. 26.
Kontrollieren Sie nach einer Kollision stets die 
Synchronisierung.
Wenn die Messer nicht synchronisiert sind, kann 
im Mähwerk einer der folgenden Fehler vorliegen:
 Der Zahnriemen ist vom Zahnrad gerutscht.
 Die Drehzahlbegrenzung zwischen Zahnrad  und Messerwelle wurde ausgelöst. Die Pfeile 
auf Abb. 27 müssen bei einer intakten Einheit 
aufeinander weisen. Wenn die Drehzahlbegren-
zung ausgelöst wurde, weisen die Pfeile nicht  
aufeinander.
 Der Messerbalken ist falsch an der Messerwelle  befestigt. Eine Montage ist in drei Stellungen 
möglich. Siehe 25:R.
Liegt eine falsche Synchronisierung aufgrund der 
ersten beiden Fälle vor, wenden Sie sich zwecks 
Reparatur an eine autorisierte Werkstatt.
6.16.6 Reinigung
Reinigen Sie die Unterseite des Mähwerks nach 
jedem Gebrauch. 
Stellen Sie die maximale Schnitthöhe ein und brin-
gen Sie das Mähwerk in Transportstellung. Die 
Reinigung wird erleichtert, wenn das Gerät 
darüber hinaus mit den Vorderrädern auf eine Bret-
terschicht o.s.ä. gestellt wird.
Reinigen Sie die Mähwerkunterseite sorgfältig. 
Verwenden Sie dazu Wasser und eine Bürste.
Wenn die Oberflächen gänzlich sauber und 
trocken sind, ist der Lack auszubessern. Tragen 
Sie verschleißfeste Farbe auf, die für Metall 
und Außenbereiche ausgelegt ist.

3 DESCRIPTION
3.1 TRANSMISSIONThe machine is 2-wheel drive and is driven by the 
rear-wheels.
The rear axle has a differential, which distributes 
the power equally to the rear wheels. So that the 
machine can be steered by the rear wheels they are 
equipped with CV joints that give a very smooth 
rotational transfer.
So that drive works optimally over uneven ground, 
the front axle is flexibly suspended and can move 
+/-4.5° in relation to the rear axle.
The cutting deck is driven via drive belts. 
3.2 STEERINGThe machine has rear-wheel steering. The rear-
wheel steering means that the machine can easily 
turn around trees and other obstacles. The steering 
force is transferred via a cable. 
						

							54
ENGLISHEN
3.3 SAFETY SYSTEM The machine is equipped with an electric safety 
system. The safety system stops certain activities 
that may be hazardous in the event of incorrect op-
eration. 
E.g. The engine can only be started if the cutting 
deck is deactivated.The safety system’s function must al-
ways be checked before use.
3.4 CONTROLS
3.4.1 Steering wheel (1:B)
The steering wheel is used to steer the machine. 
Only use the steering wheel when the machine is 
moving.Never turn the steering wheel when the 
machine is stationary with the cutting 
deck lowered. Risk of abnormal loads 
and damage to the steering mechanism.
3.4.2 Clutch - brake (1:D)

 Clutch
 Service brake
 Parking brake
The pedal has three positions: 1. Released  – forward drive en-
gaged. The machine will move if 
a gear is engaged. Service brake 
not activated.
2.  Depressed halfway  – forward 
drive disengaged, gear shifting can be per-
formed. Service brake not activated.
3.  Fully depressed – forward drive disengaged. 
Service brake fully activated. Also see “Parking 
brake” below.
NOTE! You must never regulate the operating 
speed by slipping the clutch. Use a suitable gear 
instead, so that the right speed is obtained.

A control for setting the engine speed and to choke 
the engine when starting from cold. 
If the engine runs unevenly there is a 
risk that the control is too far forward 
so that the choke is activated. This dam-
ages the engine, increases fuel con-
sumption and is harmful to the 
environment.
1. Choke – for starting a cold engine. The 
choke is located in the top of the groove. 
Do not drive in this mode when the en-
gine is hot.
2. Full throttle – when the machine is in 
operation, full throttle should always be 
used. 
Full throttle is approximately 2 cm behind 
the choke position.
3. Idling.
3.4.4 Ignition lock (1:M)
Ignition lock used for starting and stopping the en-
gine.  Do not leave the machine with the key 
in position 2 or 3. There is a risk of dis-
charging the battery and causing dam-
age to it.
Four positions: 1. Stop position – the engine is short-
circuited. The key can be removed.
2 and 3. Operating position 
4. Start position – the electric start motor 
is activated when the key is turned to the 
spring-loaded start position. Once the en-
gine has started, allow the key to return to 
operating position 2 or 3. 
3.4.5 Gear lever (1:J) Never shift gears whilst driving. The 
machine must be stationary with the 
service brake depressed before shifting.
The gear lever is used to select one of the three for-
ward gears in the gearbox (1-2-3), neutral (N) or 
reverse (R).

less the engine casing is closed. Risk of 
burns and crushing injuries.
5.1 TRANSPORTATION
Never drive the machine off a trailer 
with the engine running. Risk of the 
machine tipping over and causing ma-
terial damage or fatal injury. 
If the machine is transported on a flatbed or trailer, 
the machine must be pushed or lifted off/on. The 
machine must never be driven off/on with the en-
gine running as driving on slopes requires great 
care and the maximum permitted incline can easily 
be exceeded. Also see “5.5.2” and “5.5.3”.
5.2 FILLING THE FUEL TANKAlways use lead-free petrol. You must  never use 
2-stroke petrol mixed with oil.
NOTE! Normal unleaded petrol is perishable and 
must not be stored longer than 30 days.
Environmental petrol can be used, i.e. alkylate pet-
rol. This type of petrol has a composition that is 
less harmful for people and nature.
Petrol is highly inflammable. Always 
store fuel in containers that are made 
especially for this purpose. 
Only fill or top up with petrol outdoors, 
and never smoke when filling or top-
ping up. Fill up with fuel before starting 
the engine. Never remove the filler cap 
or fill with petrol while the engine is 
running or still warm.
Fill with petrol as follows:
1. Fold the seat up.
2. Open the fuel cap (6:R).
3. Fill with petrol carefully.
4. Reinstall the fuel cap and fold the seat down. 
						

							56
ENGLISHEN
Never completely fill the petrol tank. Leave an 
empty space (= at least the entire filler tube plus 1 
- 2 cm at the top of the tank) to allow the petrol to 
expand when it warms up without overflowing.
5.3 LEVEL CHECK, ENGINE OIL On delivery, the crankcase is filled with 
SAE 10W-30 oil.
Check the oil level every time before using to 
ensure it is correct. The machine should be 
standing on level ground.Wipe clean around the oil dipstick (7:S). 
Unscrew and pull it up. 
Wipe the dipstick. 
Slide the dipstick down completely and tighten it.
Pull up the dipstick again. Read off the oil level. 
Top up with oil to the “FULL” mark (7:T) if the oil 
level is below this mark.
The oil level must never exceed the “FULL” mark. 
This can cause the engine to overheat. Drain the oil 
to the correct level if the oil level exceeds the 
“FULL” mark.
5.4 SAFETY CHECKSCheck that the results of the safety checks below 
are met when testing the relevant machine.
The safety checks must always be car-
ried out before use.
If any of the results below are not met, 
the machine must not be used. Take the 
machine to a service workshop for re-
pair.

ENGLISHEN
Reduce the speed on slopes and when 
making sharp turns to prevent the ma-
chine from tipping over or you losing 
control.
Do not turn the steering wheel to full 
lock when driving in top gear and at full 
throttle. The machine can easily topple 
over.
Never drive with the engine casing 
open.
Never drive with the deck connected in 
the transport position. This will damage 
the deck’s drive belt.
5.6 CUTTING
5.6.1 Cutting height
The best cutting results are achieved when the 
when the top third of the grass is cut off. I.e. 2/3 of 
the length of the grass remains.
If the grass is long and has to be cut significantly, 
cut twice using different cutting heights.
Do not use the lowest cutting heights if the lawn 
surface is uneven. This would entail a risk of the 
blades being damaged against the surface and the 
lawn’s top layer of soil being removed.
5.6.2 Composting/rear ejection
The deck can cut grass in two ways:
 Compost the grass into the lawn.
 Eject the grass behind the deck.
The deck is set for composting on delivery. In or-
der to eject the grass behind the deck, the plug 
(16:P) must be removed. 
See “6.16.2” and “6.16.3” on how to dismantle and 
assemble the cutting deck.
5.6.3 Mowing advice
In order to achieve optimum mowing results, fol-
low the advice below:
 Cut frequently.
 Run the engine at full throttle.
 The grass should be dry.
 Use sharp blades.
 Keep the underside of the cutting deck clean.
5.7 STOP
If the machine is left unattended, re-
move the ignition key.
The engine may be very warm immedi-
ately after it is shut off. Do not touch the 
silencer, cylinder or cooling fins. This 
can cause burn injuries.
1. Depress the clutch – brake pedal fully.
2. Set the gear control to neutral (N). 3. Disengage the cutting deck.
4. Allow the engine to idle 1 - 2 minutes. Then 
turn the ignition key to the stop position so that 
the engine stops.
5. Lock the parking brake.
5.8 CLEANING
To reduce the risk of fire, keep the en-
gine, silencer, battery and fuel tank free 
from grass, leaves and oil.
To reduce the risk of fire, regularly 
check the machine for oil and/or fuel 
leakage. 
Never use high-pressure water. This can 
damage shaft seals, electrical compo-
nents or hydraulic valves.
Never use high-pressure air against the 
radiator fins. This will damage the fin 
structure. 
Clean the machine after use. The following in-
structions apply to cleaning:
 Do not point jets of water directly at the engine. 
 Clean the engine with a brush and/or com- pressed air.
 Clean the engine’s cooling air intake (7:U).
 After cleaning with water, start the machine and  any cutting deck to remove the water that may 
otherwise penetrate bearings and cause damage .
6 MAINTENANCE 
6.1 SERVICINGIn order to keep the machine in good condition, as 
regards reliability and operational safety as well as 
from an environmental perspective, the mainte-
nance work described in this chapter must be fol-
lowed according o the instructions and at the stated 
intervals.
This work should be carried out by an authorised 
workshop, but can also be carried out by the user. 
Service, carried out by authorised workshops, 
guarantees a professional job with original re-
placement parts.
We recommend taking the machine to an author-
ised workshop after each season before it is stored 
for the winter.

ENGLISHEN
6.2 PREPARATION
Prevent the machine from rolling by al-
ways applying the parking brake.
Prevent unintentional starting of the 
engine by removing the ignition key. 
All service and all maintenance must be carried out 
on a stationary machine with the engine switched 
off.
6.3 RAISING
Jacks must only be placed in the desig-
nated area. Placing the jack in other lo-
cations will damage the machine. 
The machine must only be raised on 
hard, stable and horizontal surfaces. 
Otherwise there is a risk of the machine 
dropping. 
The machine must never be loaded with 
further weight when it is raised. No-
body must sit on the machine when it is 
raised. 
For certain maintenance work, the rear part of the 
machine must be raised slightly so that the re-
quired rear wheel can be removed. Raise the ma-
chine as follows:
1. Position the machine on a hard, stable and hor- izontal surface.
2. Raise the machine using a jack, see fig. 12.
6.4 WHEELSFor certain maintenance work, it is necessary to re-
move a rear wheel. 
Dismantling
:
1. Raise the machine according to  6.3.
2. Remove the cover disc (13:A).
3. Use a 17 mm wrench and remove the screw  (13:B) with disc.
4. Pull the wheel from the axle.
Assembly
:
1. Slide the wheel onto the axle.
2. Install the screw (13:B) with disc.
3. Tighten the screw to 40-45 Nm.
6.5 TYRE PRESSUREAdjust the air pressure in the tyres as follows:
Front: 1.2  bar (17 psi).
Rear: 1.2 bar (17 psi).
6.6 CHANGING ENGINE OILChange the engine oil for the first time after 5 
hours of operation, and subsequently after every 
50 hours of operation or once a season. 
Change the oil more often (after 25 hours of oper-
ation or at least once a season) if the engine has to 
operate under demanding conditions or if the am-
bient temperature is high.
Use oil according to the table below.
Use oil without any additives.
Do not fill with too much oil. This can cause the 
engine to overheat. 
Change oil when the engine is warm.
The engine oil may be very hot if it is 
drained off directly after the engine is 
shut off. So allow the engine to cool a 
few minutes before draining the oil.
6.6.1 Draining
1. Raise the machine so that the left rear wheel is  raised a few cm above the ground. See 6.3.
If the machine is raised too much, oil cannot 
run freely in the chassis ducts whilst drain-
ing.
2. Remove the left-hand rear wheel. See 6.4.

6.11 BATTERYNever overcharge the battery. Over-
charging can damage the battery.
Do not short-circuit the battery’s termi-
nals. Sparks occur which can result in 
fire. Do not wear metal jewellery which 
can come into contact with the battery 
terminals.
In the event of damage to the battery 
casing, cover, terminals or interference 
to the strip covering the valves, the bat-
tery should be replaced.
The battery is a valve-regulated battery with 12 V 
nominal voltage. The battery fluid does not need to 
and cannot be checked or topped up. The only 
maintenance that is required is charging, for exam-
ple after extended storage.
The battery must be fully charged be-
fore being used for the first time. The 
battery must always be stored fully 
charged. If the battery is stored while 
discharged, serious damage will occur. 
6.11.1 Charging with the engine
The battery can also be charged using the engine’s 
generator as follows:
1. Install the battery in the machine as shown be- low.
2. Place the machine outdoors or install an extrac- tion device for the exhaust fumes.
3. Start the engine according to the instructions in  the user guide.
4. Allow the engine to run continuously for 45  minutes.
5. Stop the engine. The battery will now be fully  charged.
6.11.2 Charging using battery charger
When charging with the battery charger, a battery 
charger with continuous voltage must be used.
Contact your dealer to purchase a battery charger 
with constant voltage.
The battery can be damaged if a standard type bat-
tery charger is used. 
6.11.3 Removal/Installation
The battery is placed under the seat. See fig. 4. 
During removal/installation of the battery, the fol-
lowing applies regarding connection of the cables:
 During removal. First disconnect the black ca- ble from the battery’s negative terminal (-). 
Then disconnect the red cable from the battery’s 
positive terminal (-).

 During installation. First connect the red cable to the battery’s positive terminal (+). Then con-
nect the black cable to the battery’s negative ter-
minal (-).
If the cables are disconnected/connect-
ed in the wrong order, there is a risk of 
a short-circuit and damage to the bat-
tery.
If the cables are interchanged, the gen-
erator and the battery will be damaged.
Tighten the cables securely. Loose ca-
bles can cause a fire.
The engine must never be driven with 
the battery disconnected. There is a risk 
of serious damage to the generator and 
the electrical system.
6.11.4 Cleaning
If the battery terminals are coated with oxide, they 
should be cleaned. Clean the battery terminals with 
a wire brush and grease them using terminal 
grease.
