Mulchers for Excavators
Available in the following versions: BL3/EX/VT, BL3/EX/SONIC 

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.

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%.

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.

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.

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.

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.
