BIO-90 High-Speed Brush chipper on BCS 853 walk-behind tractor

This video demonstrates the relative speed of processing woody material of the BIO-90 high-speed chipper, as compared to the "large" combination Chipper/Shredder unit (BIO-100, which we also have a video we link to on our website)...as you can see, it is over 3 times as fast. This machine requires a minimum HP of 13hp gas or 11hp diesel. The wood being chipped in this video is Wild Cherry, which is about the "middle" of the hardness scale on wood types. www.earthtools.com
