PÖTTINGER protects your loader wagon with our patented individual knife protection system. Foreign objects are a danger to your livestock and the loader wagon. Moreover, downtime is costly andreduce the quality of the forage.
The triggering force of the knife protection system is adapted to the high throughput capacity. The knives are held in the correct position to make sure that they chop consistently. The knife retention springs and rollers on the individual knife protection system are swung safely out of the way. This greatly reduces the contamination of the knife holders.
1 Foreign objects trigger the protection system. The knife moves in the direction of crop flow.
2 The trigger roller is lifted out of its holder behind the knife.
3 The resistance of the knife is suddenly reduced so that the knife can allow the foreign object to pass through.
4 The knife is then automatically returned to its original position.
Any stones in the forage are not pulverised. The livestock leave the foreign objects untouched at the feed barrier, thus preventing injuries to the digestive tract.
