FAE is expanding its range of forestry mulchers for excavators with the new UMM/S/EX model for excavators up to 40 tons, particularly for feller bunchers. 

The new UMM/S/EX can be used for mulching trees and vegetation with a diameter of up to 16 inches and is compatible with excavators from 25 to 40 tons. Its hydraulic capacity ranges from 66 to 119 gpm, and it can handle pressure of up to 400 bar. This mulcher model is recommended for use anywhere a large mulching capacity is required, including in wooded areas or green spaces. 

The UMM/S/EX has been designed with several specific features to provide top performance. The mulcher’s VT automatic variable displacement motor allows for increased torque, and its Poly Chain belt transmission ensures optimum power transfer and reliability over time. Spike PRO bolted counter blades produce very fine mulch and make maintenance easy, while the mulching chamber features bolted protections made of an anti-wear material. The sturdy type-C rotor makes it possible to use different tooth models for different applications and comes with side teeth, which help keep the crushing chamber clean at all times. Finally, with a sturdy steel frame, the UMM/S/EX is designed to last.
