The ‘planing principle’ is at the base of the Jo Beau® drum technology™. To guarantee a long service life for the knives chipping into the wood, constantly at a speed that cannot be followed, Jo Beau has designed a sophisticated manufacturing section. The steel type, the hardening and the design are at the origin of the high-quality knives. The 2 hardened knives chipping the branches and the leaves against the fibre direction (Jo Beau® drum Technology™), function as a 'planing ' principle, chipping the wood in small uniform wood chips. The wood chips can be used perfectly as decoration (floor covering), composting, ground fertilisation and biofuel. The original Jo Beau knives are identifiable thanks to the engraved brand name, knife type and the unique serial number.
