BM40 is a professional scarifi er with fix ed blade collect ion. Thanks to th e blade fixing system, t heir replacement does not require the complete disassembly of the transmission and rotor, but only of the worn blades. The high-p erformance rotor guarantees excellent work in all conditions, even when the cutting edge of the blade is not in optimal condition. In addition, the collecto r with hydraulic discharge on the ground allows the material removed from the ground to be collected in a single pass. The high ventilation created by the rotor allows it to be used also as a lea f vacuum.
