The BL4/EX/VT for 18-25 ton excavators mulches logs up to 12 in in diameter and comes in two working widths: 53 in and 63 in. The BL4/EX/VT is ideal for handling and removing vegetation in wooded areas, especially for jobs that require a large shredding capacity and speed. The rotor features Bite Limiter technology. Steel profiles limit the reach (bite) of the teeth, reducing the amount of power needed and guaranteeing constant working speed and excellent performance. The heat-treated forged-steel BL/MAX blades are made to last and can be sharpened to keep operating costs lower. The timing belt transmission ensures optimum power transfer and reliability. The BL4/EX/VT has a Variable Torque (VT) motor for noticeably better performance, increased torque when needed, and minimal risk of rotor stalling. The sturdy steel frame is built to last. Spike Pro bolted counter-blades produce very fine mulched material and make maintenance a snap. The optional Sonic system ensures that the operating machine and the FAE mulcher are perfectly aligned by automatically calibrating and constantly regulating the mulcher's hydraulic parameters for a significant increase in productivity.
