Coupling
Increased risk of injury
When the machine is being coupled to the tractor, there is an increased
risk of injury. Therefore:
•Only couple the machine with the road chassis raised
•Secure the tractor against rolling away
•The tractor and machine must belong to the same category
•Never stand between the tractor and the machine during coupling
•Actuate the three-point power lift system slowly and carefully
Failure to observe these instructions can result in serious or fatal injury.
Connect electric wires or cables only after mounting the attach-
ment
The electrical supply to the tractor must not be connected when the
lighting equipment is being fitted. Short circuits and damage to the elec-
tronics are possible.
Only connect hydraulics at zero pressure
Only connect hydraulic hoses to the tractor hydraulic system if the trac-
tor and machine hydraulic system is at zero pressure. A hydraulic sys-
tem under pressure can trigger unpredictable machine movements.
High pressures in the hydraulic system
The hydraulic system is under high pressure. Regularly check all lines,
tubes and screwed connections for leaks and externally visible damage.
Only use suitable tools when looking for leaks. Rectify any damage im-
mediately. Oil escaping under pressure may result in injuries and fires.
In the event of injuries, seek medical attention immediately.
Colour-coded hydraulic hoses
To prevent operating errors, plug sockets and plugs for hydraulic con-
nections between the tractor and the machine must be colour-coded.
Wrongly connected hydraulic hoses can trigger unpredictable move-
ments of the machine.

Safety
Centre of gravity
Observe the total weight, axle loads, tyre load-bearing capacity
and minimum ballast specifications
The front or rear mounting of machines must not cause the tractor's per-
missible total weight, its permissible axle load or its tyre load-bearing
capacity to be exceeded. In order for steering capability to be main-
tained, the front axle must bear at least 20 % of the tractor's empty
weight.
By investing some effort in making the calculations it is possible to de-
termine the:
•Total weight
•Axle loads
•Tyre load-bearing capacity and
•Minimum ballast
For this calculation, the following data is required:
Data from the tractor's operating manual:
Data from this operating manual:
Data which you can determine by measuring:
•(A) unladen weight
•(B) front axle load
•(C) rear axle load
Please take into consideration, for example, the weight of water in the
tyres, accessories, etc.
•(D) total weight of the machine when rear-mounted; the supporting
load with the machines attached
•(E) total weight of the machine when front-mounted
•(F) distance between the machine's centre of gravity when front-
mounted and the front-axle midpoint
•(G) distance between the lower link ball midpoint and the machine's
centre of gravity when rear-mounted. With machines attached, G=0.

Tyre load-bearing capacity
Data on the tyre load-bearing capacity of the front and rear wheels can
be found in the tyre manufacturer's documentation.
•The front tyre load-bearing capacity for two wheels is equal to twice
the permissible tyre load-bearing capacity of a single front wheel.
•The rear tyre load-bearing capacity for two wheels is equal to twice
the permissible tyre load-bearing capacity of a single rear wheel.
Summary
Check if the following conditions are met:
•The actual values for the rear axle load must be less than the per-
missible values given in the tractor's operating manual.
•The tyre load-bearing capacity must be greater than the values for
the rear axle load given in the operating manual.
•The actual total weight must be less than the permissible total weight
given in the tractor's operating manual.
If these conditions are not met, the machine must not be attached to this
tractor.
If you have a sufficiently large weigh-bridge, you can determine the total
weight and the rear axle load by weighing.

Safety
Road transport
Make sure that the condition of the machine conforms to road traf-
fic regulations
The machine must conform to current traffic regulations if you intend to
drive it on public roads. This includes for example:
•Fitting lighting equipment, warning devices and protective devices
•Observing the permissible transport widths, transport weights, axle
loads, tyre load-bearing capacity and total weights
The driver and owner of the vehicle are liable if traffic regulations are not
observed.
Closing ball valves
If ball valves are provided on the hydraulic lines or the chassis cylinders,
the ball valves must be closed for road transport. Accidental actuation
of control devices on the tractor might otherwise cause movements in
the machine. Accidents or damage to the machine may be caused as a
result.
Check release cable for the quick-release coupling
Release cables must hang loose and must not, when in their lowered
position, release the couplings of their own accord. Attached machines
might otherwise come loose from the three-point linkage of their own ac-
cord.
Riding on the machine is strictly prohibited
People or objects must never be transported on the machine. Riding on
the machine poses a risk to life and limb and is strictly prohibited.
Take altered driving and braking behaviour into account
Driving and braking performance is altered when the machine is at-
tached to the tractor. Take the width and balancing weight of the ma-
chine into consideration, especially when cornering. A driving style
which not adjusted to the road conditions can lead to accidents.
Drive at a suitable speed
Always adjust your driving speed to the road conditions. Driving at ex-
cessive speeds in poor road conditions may create extremely large forc-
es, which will severely load or overload the tractor and the machine.
Driving at unsuitable speeds can cause machine damage and lead to
accidents.
Putting the
machine into oper-
ation
Training required before commissioning
The machine must not be put into operation until the user has been giv-
en proper training by an employee of the dealer, a factory representa-
tive, or an employee of the manufacturer. Commissioning without train-
ing can lead to damage to the machine due to false operation or acci-
dents can happen.
Ensure that the machine is in perfect working condition
Do not operate the machine unless it is in perfect working condition.
Check all important components and replace any defective components
before starting the machine. Defective components can cause damage
to equipment and personal injury.

MU-B

Safety
Do not remove the protective equipment
The protective equipment must not be removed or by-passed. Check all
protective equipment before starting the machine. Unprotected ma-
chine parts can cause serious or fatal injury.
Riding on the machine is strictly prohibited
People or objects must never be transported on the machine. Riding on
the machine poses a risk to life and limb and is strictly prohibited.
Height of the machine and overhead power lines
If a height of 4.00 m is exceeded when folding the machine in and out,
the machine must not be folded in the vicinity of live overhead power
lines. Danger of electrocution! Should the machine come into contact
with a live overhead power line:
•Do not attempt to exit the tractor cabin
•Do not touch any metal parts on the tractor
•Do not create any conductive contact with the ground
•Warn all persons in the area not to approach the tractor or the
machine
•Wait for help from professional emergency service personnel as
power in the live overhead power line must first be switched off
Never climb onto the machine beneath live overhead power lines. The
voltage can jump across even if the lines are not actually touching the
machine.
Check the hazard area
Before driving off, folding out, and operating the machine and during op-
eration, check its hazard area. Make sure that you have an adequate
view. Do not begin work until the hazard area is cleared of any persons
or objects. Information regarding the hazard area can be found in the
corresponding chapter.
Chapter »Mulching«, section »Task«, Page 32.
Parts could be ejected from the machine at high speed in certain cir-
cumstances. The hazard area, particularly in front of and behind the ma-
chine, must be cleared of any persons, animals or objects before start-
ing.
Any use of the machine without verification of the hazard area can lead
to serious or fatal accidents.
Retighten all nuts, bolts and screws
Nuts, bolts and screws should be checked at regular intervals and tight-
ened if necessary. Screws can come loose unnoticed while operating.
Damage to the machine or accidents may be caused as a result.
What to do in the event of a fault
In the event of a malfunction, shut down and secure the machine imme-
diately. The fault may be eliminated immediately, or a specialist work-
shop must be assigned the task. Further operation of the machine can
lead to damage to the machine or injury to persons.

MU-B

Safety
Uncoupling the
machine
Increased risk of injury
There is an increased risk of injury when uncoupling the machine from
the tractor. Therefore:
•Secure the tractor against rolling away
•Never stand between the tractor and the machine during uncoupling
•Actuate the three-point power lift system slowly and carefully
•Make sure the machine is standing on a secure and level surface
•Do not disconnect hydraulic hoses until there is no pressure in the
tractor and machine hydraulic system
Failure to observe these instructions can result in serious or fatal injury.
Care and mainte-
nance
Observe the care and maintenance intervals
Observe prescribed intervals for maintenance checks and inspections
specified in the operating manual. If these periods are not observed, this
can lead to damage to the machine, poor quality of work or accidents.
Use original replacement parts
Many components have special properties that are essential for the sta-
bility and correct operation of the machine. Unsuitable spare parts or ac-
cessory parts or incorrectly performed repairs or changes can cause
damage to the machine, accidents or serious injury.
Müthing strongly recommends using only approved original Müthing ac-
cessories and spare parts. Müthing can guarantee the safety, reliability
and suitability of these parts only.
Use of non-original Müthing spare parts shall invalidate any warranty
claims.
When performing any care and maintenance work:
•Switch off the PTO stub shaft
•Depressurise the hydraulic system
•Whenever possible, uncouple the tractor
•Make sure the machine is standing securely. Provide additional sup-
port as required
•Do not use parts of the machine as climbing aids; use only secure
steps, ladders or other means of access
•Secure the machine against rolling away
•Never reach into the V-belt while it is running
It is only possible to guarantee work safety during care or maintenance
work through observing these regulations.
Turn off the electrical supply
Prior to carrying out work on the electrical system, disconnect the sys-
tem from the power supply. Systems supplied with electrical power can
cause damage to equipment and personal injury.

MU-B
19
Safety
Replace hydraulic hoses
Replace hydraulic hoses every six years. Hydraulic hoses can age with-
out any externally visible damage. Defect hydraulic lines can lead to se-
vere or fatal injuries.
Caution when cleaning with a high-pressure cleaner
The machine can be cleaned using either water or a steam jet. Only use
a low pressure to clean bearings, fans, signal mixer units, plastic parts
and hydraulic hoses. Excessively high pressures can cause damage to
these parts.
Before carrying out welding work, disconnect the battery and al-
ternator
Before carrying out any electric welding work on the attached machine,
disconnect the tractor battery and the alternator. This avoids damage to
the electrical system.
Tighten all screwed connections
All screw connections that are released during maintenance and repair
work must now be retightened. Loose screwed connections can cause
bolts to undo without you noticing during your work. As a result, ma-
chine parts can become detached. Otherwise, this may result in severe
injury or damage to equipment.
Further regula-
tions
Observe the regulations
In addition to these safety instructions, observe the following:
•Accident prevention regulations
•Generally recognised safety regulations, occupational health re-
quirements and road traffic regulations
•Information and instructions in this operating manual
•Operation, maintenance and repair instructions
