2025 FAE BL4/EX Sonic-125

The BL4/EX/VT for 18-25 ton excavators mulches logs up to 30 cm in diameter and comes in two working widths: 135 cm and 160 cm.

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.
