Mulchers for Skid Steers
Available in the following versions: BL4/SSL/VT, BL4/SSL/SONIC 

The BL4/SSL forestry mulcher, designed for Skid steers from 90 to 135 ch and is able to shred material up to 12 inches in diameter. Thanks to the Bite Limiter technology this head is ideal to have high productivity in vegetation management and provide high and efficient shredding in wooded and forestry areas. The head is designed to offer high productivity, durability and ease of maintenance for the operator. The BL4/SSL is available in VT version or with Sonic, a FAE exclusive technology that optimize that optimizes performance and can be easily calibrated using the dedicated FAE App for smartphone.

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.

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.
