BM40 is a professional scarifier with fixed blade collection. Due to the blade fixing system, their replacement does not require the complete disassembly of the transmission and rotor, but only of the worn blades. The high-performance rotor guarantees excellent work in all conditions, even when the cutting edge of the blade is not in optimal condition. In addition, the collector 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 leaf vacuum.
