BM50 is a professional scarifier with fixed blades . Thanks to the blade fixing system, t heir replacement does not require the complete disassemb ly of the transmission and rotor, but only of the worn blades. The high-performance rotor guarantees excellent work in all circumstances, even when the cutting edge of the blade is not in optimal condition. In the standard version the blades are in HARDOX material with a thickness of 3 mm and spaced by 30 mm.
