• „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

How the VFS system works: As the first step, the packer in combination with a feeder bar feed the material into the feed chamber where it is collected and pre-compressed. Once the feed chamber is filled to capacity, the feeder bar pushes the crop into the bale chamber. The VFS Variable Filling System from KRONE delivers rock-hard bales that keep their shape even in thin swaths and at slow forward speeds.

Depending on the model, the VF system operates with three or four packer rakes and one feeder rake plus one retainer. The packers run in a shared cam track, the feeder rake in a separate cam track that swings into and off path.

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 feed chamber is filled with material, the retainer gives way to the pressure and clears the way for the material to enter the baling chamber, releasing a clutch at the same time.

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 previous positions.
