Brittle crop material

While pressing brittle crop material it is recommended to move
the cutting device into home position short before wrapping
process. In this way the bale is finally wrapped with long
material and crop losses are minimised.
7.6 Assembly and disassembly of the
cutting device knives
Note!
By removing individual knives the cut length of the baling
material can be changed. (This counts mainly for the 13-knife
cutting device. At the 17-knife cutting device and the 25-knife
cutting device the same effect can be got by selecting knife
groups).
If no cutting function is desired for a longer period of time, all
knives can be removed.
25-knife cutting device: to optimise material flow in the
conveying elements and to stabilise the side faces of the bales
(in case of dry straw), the two outer knives of the cutting device
should be removed.
Attention, danger of injury!
Wear protective gloves while working with the knives.
If any maintenance or assembly work is carried out with the tail
gate open, the tail gate must be hydraulically secured against
lowering for safety reasons:
For the following working steps:
see chapter 7.3Moving in and out the cutting device.
Move cutting device to cutting position.
Swivel the bottom door* about half way down.
Open and secure tail gate (see chapter 9.3Eject bales).
Figure 73: Swivel lever of the knife axle on the feeder
housing (on the right in driving direction) down through about
90° as far as the stop .
Using tongs withdraw the knives diagonally upwards from
the knife axle and remove them from the slot proceeding
from the roll chamber.
