4. Mulching instructions

4.1 General information

During mulching, the cut grass is chopped
up several times through a special air flow
guidance system in the mower blade area
and then blown back into the turf. The
clippings remain on the lawn.
The decomposing clippings return organic
nutrients to the soil, serving as a natural
fertiliser.
Emptying the grass catcher box and
disposal of the clippings are dispensed
with. Weed growth is slowed down and
significant amounts of fertilizer are saved.
4.2 How should mulching be
performed?
● Frequency:
At least twice a week in the spring (main
period of growth) and at least once a
week in the summer and autumn.
● Cutting height:
Remove approximately one third of the
grass height, only use cutting heights 4
to 7.
6
● Mulch the lawn when dry.
● Work with well-sharpened blades.
● Vary the mowing direction and ensure
that the mowing strips overlap.
● Always cut very high grass in stages.
