10.8 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.
Level indicator:
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.
Emptying the grass catcher bag:
Risk of injury!
Always disengage the mowing
blade before emptying. (
Take weight into account!
A completely filled grass catcher
bag can weigh up to 22 kg.
Avoid damage to the machine!
Always empty the grass catcher
bag in good time in order to prevent
the mowing channel from becoming
obstructed. Obstructions can block
the mowing blade and lead to
unnecessary wear of the blade
brake clutch.
