Starting The Motor - AL-KO Highline 51.8 SP-A Betriebsanleitung

Mowing without the grass catcher
Caution!
Only work without the grass catcher if the
defl ector plate torsion spring is working correctly.
The defl ector plate is held to the mower housing by
spring force. This causes the mowed grass to be thrown
backward and downward.
Mulching with the mulch kit (optional)
When mulching, the grass cuttings are not collected, but
are left on the lawn. The grass mulch prevents the soil
from drying out, and supplies it with nutrients.
The best results are obtained by cutting back regularly
by about 2 cm. Only young grass with a soft leaf texture
decomposes quickly.
 Grass height before mulching: 8 cm maximum
 Grass height after mulching:
Adapt your walking pace to the mulching process,
do not walk too fast.
