11.3 Mulching
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 surface where they partially decompose
and serve as a natural fertiliser. To ensure a per‐
fect, thick lawn, mulch regularly, removing one
third of the grass height.
Requirements for good mulching results:
– Frequency: at least twice a week in the spring
(main period of growth) and once a week in
the summer and autumn.
– Mow the lawn when dry if possible.
– Use well-sharpened cutting blades.
– Select a low rate of feed.
– Vary the mowing direction and ensure that the
mowing strips overlap.
– Always mow very tall grass in stages.
