High density bales with a moderate core

Progressive density bale formation
Key to the latest generation RV balers is the development of a progressive density bale formation system for improved bale structure. As the bale grows within the bale chamber, the belt tensioning arm is subjected to steadily increasing resistance from 2 hydraulic cylinders and a spring tensioner. So as the bale diameter grows, so does the bale's density.

The result is a very firm bale with a moderate core - not too soft, or too hard. With a tougher outer shell, straw bales will be more tolerant to poor weather conditions, while silage bales will maintain their shape for improved stacking and easier handling.
