5.4.3 Adjusting the attachment drive
Function/recommendations
The proportional pressure control valve (PCV) makes it possible to adjust
the maximum hydraulic oil pressure for the attachment.
The proportional flow control valve (FCV) makes it possible to adjust the oil
quantity for the attachment.
NOTE
When operating the mulcher, a higher pressure is required than when
operating the mowing unit. If both units are used alternately, we
recommend a proportional pressure control valve (fitted as standard
from 2019) to protect the mowing unit against overload in case of
blockages and to enable a soft start of the mulcher.
Adjusting oil pressure or oil
quantity
To adjust the oil pressure or oil quantity of the attachment drive:
a) Adjust values according to the specifications in the chapter Possible

NOTICE
Damage to equipment due to overload or blockages!
With the optional proportional flow control valve (FCV), the maximum
pressure is always 260 bar. The mowing unit is then not protected
against damage in the event of overload or blockage.
