Instruction manual – MU-C/S 5
2. Important operating and safety instructions
This part of the manual is not long. Please read it right through.
Your new Müthing mulcher was expensive. But your life and personal safety are even more
valuable. So always pay proper attention to your own safety and that of other people. This not
only applies to operating the machine but also to care and maintenance. You will find detailed
instructions on safety and risks from page 16 onwards.
In order to avoid risks, work safely and maintain the value of your new Müthing mulcher for many
years to come please pay attention to all the instructions given you by our dealer and always think
before you act. Read the complete manual and familiarise yourself with the machine, its proper use,
possible risks and safe handling. It should only be operated by competent people.
1) Permissible power range. It is essential to adhere to the performance specifications for your
mulcher type and not to exceed the maximum vehicle/tractor KW ( HP ). The manual covers
mulcher types MU-C/S for tractor performance from 10-18 KW (15-25 HP). Only one type is
correct – you will find the precise details for your mulcher in the technical data inside your
spares list on page 6.
2) Mounting. As soon as you have hitched your mulcher to the tractor, remove the locking bolts from the
support legs, raise the legs and re-secure them with the locking bolts. Then gently raise the lower
links (control device floating freely) so that the headstock is precisely vertical and straight.
Readjust with the upper link if necessary.
If the mulcher is inclined too far forward it will cut too low and may clog and dig in. Having the
mulcher inclined backwards will place too much strain on the support roller. In both cases
there is a risk of debris such as stones etc flying out to the front or the rear when working. If
the lower link and the upper link are set correctly as described, the glide shoes on the mulcher
housing will be parallel with the ground.
3) P.T.O. shafts that are distorted beyond a certain extent lose their film of lubricant, run hot and
the universal joints fly apart. Look out for distortion and grease regularly! Ensure that distortion
at the front of the P.T.O. joint more or less matches that at the rear (uniform Z-diffraction
required).
4) The height of the mulcher is set via the back-up roller (basic setting by means of the three
holes) and the upper link (fine adjustment). On the roller you should generally use the central
hole on the side plate. Don't cut too short! Give the grass a chance to sprout up again
In unfamiliar areas such as fallow ground and field edges it is a good idea to use the lower
hole, i.e. cut higher. There is no way of telling what debris and rootstalks are lurking there.
If possible, steering device of 45 – 90°cylinder at floating position! The machine should adjust
to the ground of its own accord. This takes pressure away from pivots and cylinders.
5) Driving. If the mulcher is taken round sharp bends on the back-up roller even the best
bearings in the world cannot stand this indefinitely. Lift it off or raise the mulcher on bends and
when turning.
6) Speed. The slower the better! The longer the chaff remains in the housing, the more it is cut
and crushed, meaning that it will rot better and more quickly. – Driving slowly at the edges of
fields, roads and tracks also makes it easier to stop in time to avoid obstacles.
Side marchers develop very considerable leverage. so that the left side of the tractor (or, with
left-hand models, the right side of the tractor) can encounter a substantial reduction in load,
especially when taking bends. Drive with consideration!
7) Quality of cut. Keep as close as possible to the stated P.T.O. speed – never exceed it! If the
rotor can operate at the rated speed, suction is intense and crushing is good. If the engine
speed is too high the rotor, bearings and the power train could be damaged
