7. Cutting Device*
RP 220 • RP 320
Depending on the model, the baler can be fitted with a 12-blade
cutting device
(MASTERCUT)
or with a 23-blade cutting device
(PROFICUT)
or with a 25-blade cutting device.
It can be used for silage, hay and straw. The cutting device is
hydraulically moved in and out.
7.1. Cutting device operation
RP 220 • RP 320 MASTER / PROFI
Read and observe the separate operating manual
„BALERCONTROL III with Graphic Display for RP 220/RP 320“.
1. Press the button
on the
BALERCONTRO
L panel.
The symbol „cutting device“ appears in the display field of
the control panel (fig.43).
2. Activate the attached tractor control valve. (The actuating
direction can be changed by swapping the connected
hydraulic hoses.)
3. When the blades are in the cutting position, the symbol
“cutting device” also appears in the display field of the
control panel. Or: When the blades are not in cutting
position, the symbol „cutting device crossed out“ appears in
the display field of the control panel (fig.44).
4. In order to fill the hydraulic accumulators, operate the
control valve for at least another 2 seconds.
5. In order to ensure free movement of the individual blades, it
is recommended to move the cutting device in and out
several times each day.
Note:
The cutting device is safeguarded from being overloaded
by a single hydraulic pressure switch serving the cutter blades.
This activates at a factory set pressure limit. This is also the
pressure available for moving in the blades. Depending on the
situation, the hydraulic pressure may not necessarily suffice if
the blade grooves are blocked.
