The Bio model has been designed for quick, easy handling of slash and waste material, parts of trees and other material that is to be chipped to BioFuel, either directly into chippers during felling, or later from a stockpile. The Bio model uses reinforced boom tubes and twice the material thickness in the claws. The Bio also has mechanical end stops, which prevents the cylinders from bottoming. There is also a widened Bio model for stump handling etc.
