A new short chop system will be available for the Pöttinger Jumbo 8000 from the 1st of August, said to chop forage 30% shorter and protected to a torque of 3,500Nm. According to the company, this means the loader wagon can deliver higher throughput rates than a self-propelled forager.
Theoretical chop lengths can be reduced from 34mm to 25mm with the new chopping system, which comprises 65 knives. These are individually protected and can simply move out of the way of foreign objects. The automatic loading system can also be equipped with an optional sensor on the rotor scraper carrier, meaning that up to four sensors are used to optimise the loading process.
The new sensor system detects the pre-compaction of the forage directly above the rotor and activates the scraper floor before any damage can occur.
Short chopped forage can be compacted better, leading to a faster decrease in pH value and reducing the risk of fermentation failure. It also has a positive effect on livestock health and performance.
Because of the shorter chop length, the Jumbo also offers a 10% higher loading density. This higher payload increases the cost effectiveness of the operation as less machinery and operator time is needed.
Despite the smaller knife spacing of 25mm, it is still possible to use the Autocut automatic knife sharpening system, guaranteeing the knives are always sharp during operation – possibly reducing power requirement and fuel consumption by up to 20%.
