4 DESCRIPTION
4.1 TRANSMISSION
4.1.1 4140H, 4155H
The machine is rear wheel drive.
The rear axle is equipped with a hydrostatic 
transmission with infinitely variable forward and 
reverse gear ratios.
The rear axle is also equipped with a differential to 
facilitate turning.
Front mounted tools are driven by drive belts.
4.1.2 4155H 4WD
The machine has 4-wheel drive. The power from 
the engine to the drive wheels is transferred 
hydraulically. The engine drives an oil pump, 
which pumps oil through the rear and front axle 
drives. 
The front axle and rear axle are connected in 
series, which means that the front wheels and rear 
wheels are forced to rotate at the same speed. 
To make turning easier, both axles are equipped 
with differential. 
Front-mounted implements are powered via drive 
belts.
4.2 STEERINGThe machine is articulated. This means that the 
chassis is divided into a front and a rear section, 
which can be turned in relation to each other.
The articulated steering means that the machine 
can turn around trees and other obstacles with an 
extremely small turning radius.
4.3 SAFETY SYSTEMThe machine is equipped with an electrical safety 
system. The safety system interrupts certain 
activities that can entail a danger of incorrect 
manoeuvres. 
For example, the engine can only be started if the 
clutch-parking brake pedal is depressed.The operation of the safety system must 
always be checked every time before 
use.
4.4 CONTROLS
4.4.1 Implement lifter, mechanical (8:A)
To switch between working position and transport 
position:
1. Depress the pedal fully. 
2. Release the pedal slowly. 4.4.2 Clutch-parking brake (8:B)
Never press the pedal while driving. 
There is a risk of overheating in the 
power transmission. The pedal has the following 
three positions:
Released . The clutch is not 
activated. The parking brake is 
not activated.
 Depressed halfway . Forward drive disengaged. 
The parking brake is not activated.
 Fully depressed. Forward drive disengaged. 
The parking brake is fully activated but not 
locked. This position is also used as emergency 
brake.
4.4.3 Inhibitor, parking brake (8:C) The inhibitor locks the “clutch-brake” 
pedal in the depressed position. This 
function is used to lock the machine on 
slopes, during transport, etc., when the 
engine is not running.
The parking brake must always be 
released during operation.
Locking:
1. Depress the pedal (8:B) fully. 
2. Move the inhibitor (8:C) to the right.
3. Release the pedal (8:B).
4. Release the inhibitor (8:C).
Unlocking:
Press and release the pedal (8:B).
4.4.4 Driving-service brake (8:F) If the machine does not brake as 
expected when the pedal is released, the 
left pedal (8:B) should be used as an 
emergency brake.
The pedal determines the gearing ratio between the 
engine and the drive wheels (= the speed). When 
the pedal is released, the service brake is activated. 1. Press the pedal forward  – 
the machine moves forward.
2. No load on the pedal  – the 
machine is stationary.
3. Press the pedal backward  – 
the machine reverses.
4. Reduce the pressure on the 
pedal  – the machine brakes. 
						

							13
ENGLISHEN
4.4.5 Throttle and choke control (8:D)If the engine runs unevenly there is a 
risk that the control is too far forward 
so that the choke is activated. This 
damages the engine, increases fuel 
consumption and is harmful to the 
environment.
A control for setting the engine speed and to choke 
the engine when starting from cold.  1. Choke  – for starting a cold engine. The 
choke position is located at the front of the 
groove. 
Do not operate in this position when the 
engine is warm.
2. Full throttle  – when the machine is in 
operation, full throttle should always be 
used. 
The full throttle position is approximately 
2 cm behind the choke position.
3. Idling.
4.4.6 Ignition lock (8:E) Do not leave the machine with the key 
in position 2 or 3. There is a fire risk, 
fuel can run into the engine through the 
carburettor, and there is a risk of the 
battery being discharged and damaged.
Ignition lock used for starting/stopping the engine. 
Four positions: 1. Stop position  – the engine is short-
circuited. The key can be removed.
2/3. Operating position.  
4. Start position  – the electric start motor 
is activated when the key is turned to the 
spring-loaded start position. Once the 
engine has started, let the key return to 
operating position 2/3.
4.4.7 Power take-off (9:G) The power take-off must never be 
engaged when the front-mounted 
implement is in transport position. This 
will destroy the belt transmission.
A lever for engaging and disengaging the power 
take-off for operating front-mounted accessories. 
Two positions: 1. Lever in forward position  – power 
take-off disengaged.
2. Lever in backward position  - power 
take-off engaged.  4.4.8 Clutch release lever
A lever for disengaging the variable transmission.
2WD is equipped with a lever, connected to the 
rear axle. See (10:N).
4WD is equipped with two levers, connected to the 
rear axle (11:O) and the front axle (11:P). 
The disengagement lever must never be 
between the outer and inner positions. 
This overheats and damages the 
transmission.
The levers enable the machine to be moved by 
hand without the help of the engine. Two positions: 1. Lever in the inner position  – 
transmission engaged for normal 
operation.
2. Lever in the outer position  – 
transmission disengaged. The 
machine can be moved by hand.
The machine may not be towed over long distances 
or at high speeds. The transmission could be 
damaged. 
The machine must not be operated with 
the forward most lever in the outer 
position. Risk of damage and oil 
leakage in the front axle.
4.4.9 Seat (2:J) The seat can be folded and is adjustable 
front-rear. The seat is locked in the folded 
up position using the catch (2:S) and 
adjusted front-rear using the knobs (2:H).
The seat is equipped with a safety switch that is 
connected to the machine’s safety system. This 
means that certain dangerous activities are not 
possible when there is nobody in the seat.
4.4.10 Engine casing (3:L)
To access the fuel cock, battery and engine 
the engine is equipped with engine casing 
that can be opened. The engine casing is 
locked by a rubber strap.
The engine casing is opened as follows:
1. Detach the rubber strap (3:M) at the front edge  of the engine casing.
2. Carefully lift the engine casing back.
Close in reverse order.
The machine may not be operated 
unless the engine casing is folded down 
and locked. Risk of burns and crushing 
injuries.
4.4.11 Quick- release mounting (12:H)
The quick connections can be separated, 
which makes it very easy to shift between 
the different implements. 
						

							14
ENGLISHEN
The quick connections allow the deck to be moved 
easily between the two positions:
 Normal position with fully tensioned belt.
 4 cm behind the normal position with slackened belt so that the deck gets closer to the base 
machine.
As the belt idler is released from the belt, the quick 
connections simplify belt and deck replacement, 
and also make shifting to the washing position and 
service positions easier.
Releasing the belt tension:
1. Remove the locking pins (12:G) from both  sides.
2. Open the quick connections by depressing their  rear sections with your heel. See (12:F).
When the quick connections are 
opened, the deck arms rest loosely in 
the shaft sections. The deck must never 
be set to the service position or washing 
position without relocking the quick 
connections after unhooking the deck 
belt.
3. Carry out the necessary corrective action, e.g.:  Unhook the belt.
 Replace the deck by unhooking the deck  arms. See fig. 14.
Tensioning the belt:
First tension one side and then the other according 
to the instructions below.
Do not turn the lever using your hands. 
Risk of crushing injuries.
1. Place your foot on the lever (13:J) and carefully  turn a half turn forwards.
2. Install the locking pin (12:G).
3. Carry out the above on the other side.5 AREAS OF USE

6 STARTING AND OPERATION
The machine may not be operated 
unless the engine casing is closed and 
locked. Risk of burns and crushing 
injuries.
6.1 FILLING WITH PETROL (17:Q)Always use lead-free petrol. You must never use 2-
stroke petrol mixed with oil.
The tank holds 6 litres. The level can easily be read 
through the transparent tank.
NOTE! Ordinary lead-free petrol is a perishable 
and must not be stored for more than 30 days.
Environmental petrol can be used, i.e. alkylate 
petrol. 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 
topping 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.
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. 
See fig. 17.
6.2 CHECKING THE ENGINE OIL  LEVEL
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. 
Unscrew and pull it up. Wipe off the 
dipstick. Slide it down completely and 
tighten it. 
Then unscrew it and pull it up again. Read off the 
oil level. Top up with oil to the “FULL” mark, if 
the level comes below it. See fig. 15-16.
The oil level must never exceed the “FULL” mark. 
This results in the engine overheating. If the oil 
level exceeds the “FULL” mark, the oil must be 
drained until the correct level is achieved.
6.3 CHECKING TRANSMISSION OIL  LEVEL 
Check the oil level every time before using to 
ensure it is correct. The machine should be 
standing on level ground.
Read off the oil level in the reservoir (15, 16:R). It 
should be between the MAX and MIN marks. If 
necessary, top up with more oil.

7.  Turn the ignition key and start the engine.
8. Once the engine has started, move the throttle  control gradually to full throttle (approx. 2 cm 
behind the choke position) if the choke has been 
used. 
9. When starting from cold, do not make the  machine work under load immediately, but let 
the engine run for a few minutes first. This will 
allow the oil to warm up. 
When the machine is in operation, full throttle 
should always be used.
6.6 OPERATING TIPSAlways check that there is the correct volume of 
oil in the engine. This is particularly important 
when operating on slopes. See 6.2. 
Be careful when driving on slopes. No 
sudden starting or stopping when 
driving up or down a slope. Never drive 
across a slope. Move from the top down 
or from the bottom to the top.  The machine may not be driven on 
slopes greater than 10º in any direction.
Reduce the speed on slopes and when 
making sharp turns in order to retain 
control and reduce the risk of tipping 
over.
Do not turn the steering wheel to full 
lock when driving in top gear and at full 
throttle. The machine can easily topple 
over.
Keep hands and fingers well away from 
articulated steering joint and seat 
bracket. Risk of crushing injuries. 
Never drive with the engine casing 
open.
6.7 STOPDisengage the power take-off. Apply the parking 
brake. 
Allow the engine to idle 1-2 mins. Stop the engine 
by turning off the ignition key.
Shut off the petrol cock. This is particularly 
important if the machine is to be transported on a 
trailer for example.
If the machine is left unattended, 
remove the spark plug cable(s) and 
remove the ignition key.
The engine may be very warm 
immediately after it is shut off. Do not 
touch the silencer, cylinder or cooling 
fins. This can cause burn injuries.
6.8 CLEANING
To reduce the risk of fire, keep the 
engine, silencer, battery and fuel tank 
free from grass, leaves and oil.
