Mulching

Your lawnmower can be equipped with a mulch kit. The conversion kit to a mulch system is available as an accessory from
your specialist dealer (Order no, for conversion kit, see Original Replacement Parts and Accessories).
WARNING
The conversion of the mower to the mulch system should always be carried out by an authorised specialist
workshop. An incorrectly assembled blade clutch or blade screw which is too loose or tight can lead to detachment
of the blade, which can lead to serious injuries.

What is understood by the term mulching?

When mulching, the lawn is cut and the cut blades of grass are then, immediately thereafter, chopped several times to
become even smaller using the special mulch blade. This mulch blade straightens the grass blades and cuts the blades into
very short segments which are then distributed evenly over the lawn surface.
The grass blade segments can now dry and rot more quickly, thus facilitating the production of humus. This enables natural
fertilisation of the soil and also protects against dehydration.
Gathering and removal of cuttings is no longer necessary. The mulch concept is thus environmentally-friendly and stimulates
the ecology.

How is the perfect grass blade cut achieved?

The length of the grass to be cut should not exceed 10 cm when a mulching mower is used. A maximum of 1/3 of the grass
height is cut in one working cycle. If a positive result is not achieved, mulching may have to be repeated.
Mowing should be done regularly depending on the type of lawn and intensity of growth. During the strong growing phase in
particular, mulch-mowing needs to be done more frequently than traditional mowing with grass collection, since the one-third
rule is hard to keep otherwise.
To achieve an optimum mulching result you should reduce the machine speed for mulching compared to traditional mowing
to allow the grass to remain in the mowing blade longer and thus be cut several times.
The best cutting pattern and result are achieved on a dry lawn, since wet cut grass will stick together and clump quickly.
These grass clumps will rot and mould, preventing the desired ecological cycle.
If the lawn has to be mowed in a very damp, wet state, the cut grass must be shorter i.e. the cutting height must be set 1-2
GB
levels higher than with a dry lawn.
You will notice that if you follow these simple rules you will have a healthy lawn and can save on disposing of your grass cuttings.
If the grass should happen to be too high for mulching, the mulching mower can be converted for mowing with a grass
collecting bag in no time.

Converting the machine to rear ejection (Illustration U2 + S1 )

– Stop the engine.
– Lift up the ejection flap.
– Remove the mulch stopper from the duct U2 .
– Hang the grass collection bag in the provided holder on the mower housing S1 .
Conversion of the mulch blade system is not required! Under difficult mowing conditions (e.g. wet grass) a reduced filling
level of the collection bag can result.
In order for the equipment be used once again as muIch mower, the muIch stopper must be installed again. To do this,
remove the grass collection bag, introduce the muIch stopper in the ejection duct and close the ejection flap.

17 SERVICE INTERVALS

IMPORTANT
Avoid damage! Under extreme or unusual conditions, shorter servicing intervals than the ones specified below may
be necessary. If you establish any problems, please contact an authorised workshop.
Carry out routine servicing on the machine in line with the following servicing intervals.
Work must be carried out at the following servicing intervals in addition to the maintenance work listed in these operating
instructions.
Before initial use
• Check the oil level Y1 .
• Check all screw connections for a tight fit.
• Check the cutting blade screw and have an authorised workshop tighten it if necessary.
• Check whether the safety control bar for the blade brake is working perfectly.
• Check that all protective devices have been attached properly and are not damaged.
