7.2. Brittle crops
It is recommended when baling brittle crops to hydraulically
move the cutting device out of the cutting position before
wrapping. The bales are then enclosed by long material and
crumbling losses are avoided to a large extent.
7.3. Installation and removal of the cutter blades
The cutting length for the pressed material can be adjusted by
removing individual blades. All of the blades can be removed if
the cutting function is not needed for a longer period of time:
• Move the cutting device into the cutting position.
• Lower the HYDROFLEXCONTROL bottom flap* approxi-
mately halfway (fig. 50).
• Open the tailgate and secure it by using the cut-off valve (fig.
3).
• Pull down the blade lock lever on the conveyor housing on
the right-hand side (in the driving direction) by approx. 90°
until it stops.
• From the roll chamber, pull out the blades using pliers
diagonally up from the blade axle and remove it from the slot.
Warning: Danger of injury! Wear protective gloves when
handling blades.
If maintenance or assembly work is to be performed when the
tailgate is open, then for safety reasons it is absolutely
necessary that the tailgate be secured from lowering.
Once removed, the blades can be stored behind the right door
panel and secured in place with a plug-in split pin and a lever.
(fig. 51).
Note: Removed blades should be replaced by dummy blades*
in order to prevent the slots from becoming blocked.
