The mulcher for large excavators, with Bite Limiter technology.

Mulchers for Excavators

BL4/EX

Available in the following versions: BL4/EX/VT, BL4/EX/SONIC

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. 
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.

Technology

Sonic

Sonic is a smart, flexible system that automatically calibrates the mulcher’s hydraulic parameters thanks to an operator control box that allows the mulcher to work autonomously and constantly at maximum capacity, in all working conditions. Sonic guarantees perfect harmony between the operating machine and the FAE mulcher, increasing the machine’s performance by 30%.

Technology

VT (Variable Torque) piston motor

The VT (Variable Torque) piston motor significantly improves mulcher performance, increasing mulching torque when an extra boost of power is needed and minimizing the conditions for rotor stalling. The VT motor assists the operator with mulching, allowing for exceptional performance.

Technology

Bite Limiter rotor

The experience of the FAE Group has given rise to a new line of professional mulchers for excavators equipped with Bite Limiter technology.

The Bite Limiter rotor features special profiles in Hardox wear-resistant steel, guaranteeing an optimal cutting depth from the blades (BL/MINI, BL, BL/MAX).

This reduces the demand for power and facilitates a consistent working speed, leading to excellent performance when mulching any type of wood. The Bite Limiter also reduces the likelihood of rotor stalling and optimizes fuel consumption.

Technology

Spike Pro

Spike Pro: the counter blades that help FAE forestry mulchers handle any kind of vegetation more efficiently. Spike Pros are interchangeable offset counter blades for finer shredding and smoother flow of wet material. The special design makes them efficient with very stiff wood and more flexible shrubs.

Technology

App FAE

The official FAE App is dedicated to FAE customers who own a mulcher with Sonic technology.

The App allows you to verify optimal calibration at the time of field deployment to make the most of the Sonic system, by controlling the rotor speed and the mulching pressure. The app’s integrated diagnostics system and real-time monitoring of the main parameters assist in resolving any problems. The connectivity of the FAE App for Sonic is guaranteed by a dedicated control unit positioned on the head.
