Mulchers for Excavators

The mulcher with Bite Limiter technology for large and midsize excavators.

BL3/EX/VT for 14-20 ton excavators mulches trees with a max. diameter of 20 cm and is available in two working widths: 134 cm and 158 cm.
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.

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 (MINI BL, 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.
