Knife security
A reassuring detail
Time and cost pressures
make machine idle time an
expensive business.
Foreign bodies are a danger
to the most important
element of the trailer –
the cutting unit. Pöttinger
protects the heart of the
silage trailer with an
innovative setup –
patented foreign body
security. Each knife is
individually secured.
Functionality of the tried and tested knife security:
1. If foreign bodies are picked up, the smaller
pieces fall through baffle plates between the
pickup and the rotor.
2. Larger foreign bodies press the rotor onto the
knife and move it briefly in the direction of
rotation.
3. The trigger roll at the back of the knife is lifted
out of its holder and the knife releases the
foreign body. The resistance is minimal, which
protects the knife!
4. After the foreign body has passed the cutting
unit, the knife springs back to its original
position.
The triggering pressure is independent of the size and point of contact of the foreign body.
