Cutting unit
JUMBO 8000 with a chopped length of 25 mm
With its 65-knife POWERCUT short-chop chopping system, the JUMBO 8000 series first choice for the highest silage quality.
A theoretical chopped length of just 25 mm delivers extremely short-cut forage. The knives are individually protected against foreign objects even with this narrow knife spacing. Due to the even shorter chopped length and further optimisation of the forage quality, an even higher output can be processed.
The knife bank that swings out to the side and the hydraulic, central knife release at the touch of a button, are standard equipment on the JUMBO and ensure quick handling without the need for tools.
In addition, the fully automatic AUTOCUT knife sharpening system can be added to ensure that the blades of the knives remain sharp for a precise cut at all times.

EASY MOVE swing-out knife bank
This unique swing-out knife bank makes light work of changing and turning the knives. Press the button on the side of the wagon to swing the knife bank out. The knives simply swivel out after the mechanical safety interlock is released. Servicing is then safe and easy to perform from the side.
A central hydraulic knife release system is standard. Simply press the release button to disengage the knives so they can easily be removed without the need for tools.
Simply convenient
EASY MOVE lets you change or turn the knives simply and safely outside the loader wagon. It allows you to carry out servicing and inspection ergonomically.
Thanks to this comfortable way of working, knives are checked more often and the loader wagon is always in peak operating condition.
Knife quality
The knives are designed for optimum throughput and made of hardened DURASTAR tool steel. The serrated edge ensures a consistent and precise chop. The extra thick rear edge of the knife guarantees maximum reliability.
Individual knife protection
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.
