FAE BL1/EX/VT 75 Excavator Mulcher, Variable Piston Motor, Bite Limiter Rotor

Overview

The FAE BL1/EX/VT 75 is a compact, powerful forestry mulcher designed for excavators weighing 4 to 7.5 tons. Featuring a 31.5″ working width, it uses Bite Limiter rotor technology and a variable piston motor to cut and shred light vegetation, shrubs, and trees up to 5–6″ in diameter. Built for speed and efficiency, it handles roadside clearings, property cleanup, trail maintenance, and wildlife habitat prep with ease.

Key Features

Bite Limiter Rotor
Special steel limiter rings control blade depth to reduce power demands and maintain high working speed, preventing rotor stalling while cutting through hardwood and softwood.

Variable Torque Piston Motor (VT)
The 55 cc variable-displacement hydraulic motor boosts pressure under load, providing extra torque when needed while conserving flow during light conditions, offering stable performance across varying terrains.

Encased Design & Deflectors
A fully enclosed body, hydraulic hood, and rear deflector are built to protect internal components from debris, increasing durability in rugged conditions, while improving overall product flow.

Built to Last
The BL1 features forged steel rotor shafts, high-grade reversible blades, a secure belt transmission, and replaceable Hardox® skid plates.

Technical Specifications

Performance

The BL1/EX/VT 75 is built to maintain high rotor rpm, shredding small trees and brush. Its Bite Limiter rotor and variable torque motor balance this productivity with fuel savings and reduced rotor stalling while the enclosed frame and deflector offer excellent debris containment. With a rugged build and quick-connect hydraulic setup, it's a top performer in forestry applications where performance and durability matter most.

FAQ

How does it mount to my carrier?
The BL1 mounts via an adapter mount to your carrier. Excavator Adapter Mount Not Included - Give us a call to have one configured for your specific excavator.

What excavator size is required?
Recommended for excavators between 4 and 7.5 tons (8,000–15,000 lbs), compatible with standard auxiliary hydraulic circuits.

How large of trees can it mulch?
The BL1 is capable of mulching wood up to 5–6″ in diameter.

How does the variable torque motor work?
The variable torque motor adjusts displacement automatically as rotor speed slows, boosting torque under load to keep rotor speeds consistently high and reduce the need for reaccelerating the rotor after stalling.
