Mulching kits AMK 443, AMK 448
With a mulching kit, a conventional lawn
mower can be converted into a multi-
mower. For this purpose, the mowing
blade must be replaced with the multi-
blade.
A multi-mower can be used as a grass
collector (with grass catcher box), a rear
discharge mower (with discharge flap
closed) or a mulching mower (with a
mulching key).
1. For your safety
Observe the instruction manual for the
lawn mower, particularly the "For your
safety" and "Maintenance" sections. The
instructions for blade maintenance must
always be observed.
Disconnect the safety plug before
performing any work on the lawn mower.
Before each use, perform a visual check to
ensure that the mulch insert, multi-blade
and blade fastening are in good condition.
Only use the mulch insert in conjunction
with the multi-blade.

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.
