11.8 Grass catcher bag with anti-
dust screen
An anti-dust screen (1) is attached
on the upper side of the grass catcher bag,
which prevents fine dust from being blown
upwards in the direction of the user.
Filling:
The centre of the anti-dust screen is lifted
slightly through the air flow which is
generated by the rotary motion of the
mowing blade and is responsible for filling
the grass catcher bag.
When the grass catcher bag is full, this
flow of air is reduced and the anti-dust
screen drops down onto the grass catcher
bag:
