BL3/EX/VT for 14-20 ton excavators mulches trees with a max. diameter of 8 in and is available in two working widths: 49 in and 59 in. The rotor features Bite Limiter technology. Steel limiter rings limit the depth of cut, which reduces power demand and guarantees speed and exceptional performance. The heat-treated forged-steel BL blades are durable and can be sharpened, lowering operating costs. BL3/ EX/VT has a 110/60 cc VT (Variable Torque) motor for noticeably better performance, increased torque when needed, and minimal risk of rotor stalling.
