Forestry Mulchers for Excavators

The FAE forestry mulchers for the most powerful excavators.

The UMM/EX/VT - UMM/EX/SONIC - UMM/EX/VT/HP - UMM/EX/HP/SONIC mulchers are great for mulching vegetation and trees with a max. diameter of 18 in and are compatible with excavators from 20 to 36 t. Their hydraulic capacity ranges from 34 to 79 gal/min
The models are recommended for managing and controlling vegetation in wooded areas, maintaining green spaces, and anywhere a large mulching capacity is required.
The line offers two types of hydraulic motors: the traditional fixed-displacement piston motor and the VT model with automatic variable displacement and increased torque for the most challenging tasks. 
The Poly Chain belt transmission guarantees optimum power transfer and reliability over time. The bolted counter blades work to finely mulch the material being processed and make maintenance easier. 
Its strong steel structural frame guarantees excellent reliability over time. The mulching chamber also features welded protections made of an anti-wear material.
The large type “C” rotor that comes standard lets you attach different tooth models designated for various types of vegetation and uses.  The rotor also comes with side teeth, which help keep the crushing chamber clean at all times.
