The Variable Fill System

• High throughput thanks to multiphase feed sequence
• Pre-compression in the feed chamber for maximum filling
• Stable bales even from small swaths
• Uniformly compressed bales for higher bale weights
• Automatic overload clutch for operating at full performance capacity

Rock-solid bales every time: The VFS Variable Filling System from KRONE delivers rock-solid, stable bales even in thin swaths and at slow ground speeds. The principle of the VFS system: fi rst, the packer and feeder tines convey the crop into the feed chamber where it is collected and pre-compressed. Once the feed chamber is completely full, the feeder rake pushes the crop into the bale chamber.

Depending on the model, the VF system operates with 3 or 4 packer rakes and one feeder rake as well as a retainer. The packers run in a shared cam track whereas the feeder rakes run in a separate moving cam track.

As long as the feeder cam track does not swing off path, the packers and the feeder continue feeding material into the feed chamber, pre-compressing it as they go. The retainer holds the material in the feed chamber, preventing it from entering the baling chamber.

When the feeding chamber is fi lled to capacity, the retainer gives way to the pressure and clears the way for the material to enter the baling chamber, releasing a clutch as it does so.

The clutch swings the entire feeder cam into a different position to enable the feeder rake to feed the crop into the baling chamber. Once this cycle is completed, the retainer and feeder automatically return to their original positions.
