the bend and on the bearings. As these bearings have no differential this subjects them to a very
heavy load.
If the mulcher is taken round sharp bends on the back-up roller even the best bearings in the world
cannot stand this indefinitely. So don’t drive the mulcher on the support roller when taking bends!
Raise it on bends and when turning.
There is a similar risk when taking bends to that which results from the machine being incorrectly
mounted or set too low (support roller/wheels in the uppermost hole) in that the mulcher’s side
plates can cut into the ground and damage the soil, roots and the mulcher itself.
This can be remedied by skids mounted on the sides, now available as a regular item from
Müthing Mulchers. When using skid plates it is important to note that they should not bear the
weight of the mulcher as this would cause skid marks and damage the roots. The weight should still
be carried by the support rollers/wheels.
As far as speed is concerned: the slower the better! The longer the chaff remains in the housing the
more it is cut and crushed, which means 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.
When using the offset hydraulic cylinder always perform this operation slowly and carefully and
avoid damaging the mulcher, plant roots or the ground, and protect the tractor against strong and
unintended surges or movements.
To achieve a uniformly good 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
Müthing mulchers are capable of cutting and mulching long grasses and large quantities of
vegetation reliably. And so as a rule very few cuts are required, just one per season may provide
adequate care with maybe one follow-up. In bad weather mulching can generally be postponed to
no great disadvantage and so avoid slipping and wasting power.
The basic principles are as follows: The shorter the better and the quicker it will rot. The length of
cutcan be influenced by the driving speed and number of shredding bars (depending on type). The
more shredding bars you use, the shorter the cut. But with more shredding bars you use more
power and lower the capacity. The slower you drive, the longer the mulch spends in the housing and
the more it is chopped.
We therefore suggest: Generally speaking, only use one shredding bar. Müthing mulchers are so
constructed that a single shredding bar will produce an adequate quality of mulch. Only use a
second shredding bar (can be fitted later on larger machines) for special circumstances when you
need to cut very small (e.g. for sensitive grazers such as horses and want rotting to occur as quickly
as possible).
With mulching you can almost always wait until it is dry and the ground is in reasonable condition.
It doesn’t have to be done on one particular day.
This saves time, energy and expense compared with alternative cultivation methods.
