8.19 Level sensor (grass catcher box)

A continuous tone sounds if the grass
catcher box is full. This signals that the
grass catcher box needs to be emptied.
0478 192 9807 C - EN
Disengaging the mowing deck
stops the continuous tone.
The time for the filled grass catcher box
signal is adjusted by modifying the length
of the (grass catcher box) level sensor.
This allows you to adapt filling of the grass
catcher box to the characteristics of the
clippings.
A shorter sensor generally causes later
triggering of the signal (the grass catcher
box is filled to a greater extent, ideal for
very dry clippings).
The level sensor can be adjusted to 6
notched positions.
In delivery condition, the level sensor
(grass catcher box) is fully extended.
Adjusting the level sensor:
● Stop the engine. ( 13.3)
● Engage the parking brake. (

moving the slide (1) of the (grass catcher
box) level sensor in the direction of the
arrows.
● Attach the grass catcher box. (
