32 Instruction manual – MU-C/S
Settings
Before you start mulching adjust your mulcher to the relevant operating conditions and check that
the machine’s gearbox speed matches the tractor’s P.T.O. speed.
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.
The best cutting height is 4 -6 cm, which matches up with the middle hole on the side plate for
securing the support roller/wheels. If you are cutting dense material or driving at higher speeds the
cut can be raised by using the lower hole; to achieve an extremely close cut the back-up roller or the
wheels can be moved to the upper hole with the machine being driven at low speed.
Don't cut too short!
Don’t cut the grass too short – give it 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 root stalks are lurking there.
The cutting height must be always greater than 2.5cm (ideally 4-6 cm) and the Mulcher must not
come into contact with the ground or you will risk damaging it!
To adjust the cut raise the machine 3 – 4 cm above the ground, turn off the engine and the
machine, align the machine and once all rotating parts are at a complete standstill release the side
mounting screws for the support roller in the side plates. Then place the support roller in the desired
position and refasten the screws in this position. Retighten nuts and bolts well.
Note: Before you start work raise the mulcher slightly and support it to minimise any
risk of injury! Never work under unsupported loads!
The mulcher must be parallel with the ground when working
.
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 you are working,
endangering other people as well as yourself.
The top linkage must also be set so that the P.T.O. shaft moves parallel to the ground, the mulcher
is supported by the support rollers or wheels, and the machine sits level. The bottom edge of the
side or skid plates must be parallel with the ground.
Then centre the lower links
so that the machine cannot move to and fro in the three-point linkage.
Then set the tractor P.T.O speed to that of the mulcher as indicated on the gearbox (540
rpm).
If possible, steering device for 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.
Should it be necessary to change the machine’s gearbox speed, please have it done by a
specialised workshop!
