Purpose-Built North American 32" & 40" Carbide Drum Mulcher for 6–12 Ton Midi Excavators. Engineered in Italy by C4 Meccanica specifically for North American hydraulic flow rates and imperial working widths, the FF32 (32") and FF40 (40") pair a high-inertia rotor armed with Fixed Tungsten-Carbide Teeth and a double-bottomed Hardox® wear-steel chassis to grind standing timber, stumps, and dense boreal brush up to 6.0" (150 mm) in diameter.
Why Choose Fixed Carbide Teeth (FF Series)
Unlike swinging hammers that deflect on large trunks, fixed tungsten-carbide teeth bite immediately into standing trees up to 6" thick, frozen wood, and stumps.
North American Hydraulic Calibration (18.5–37.0 GPM @ 4,351 PSI)
Tuned specifically for high-output auxiliary circuits on CAT, John Deere, Kubota, and Bobcat 6–12 ton midi excavators.
Double-Bottomed Hardox® Chassis + Fluidbox Valve Block
Integrated shockproof pressure relief, flow control, and anti-cavitation manifold with SKF spherical roller bearings.

🔧 Excavator Mounting & Hydraulic Setup Guide
🚨 3rd-Line Case Drain Required: This piston-motor attachment requires a dedicated low-pressure Case Drain line (direct to tank) in addition to your supply/return auxiliary lines. Operating without a case drain will blow motor seals immediately.
Universal Bolt-On Top Deck (3 Easy Mounting Paths): Because excavator pin diameters and stick widths vary across brands, this unit ships with C4 Meccanica's factory-drilled multi-hole bolt-on top deck:
Option 1Bolt On Your Existing Blank Coupler Adapter
Bolt any standard North American blank quick-coupler plate (Bobcat X-Change, Kubota Wedge, CAT Pin-Grabber, Wain-Roy, or Tag) directly to the pre-drilled top deck—zero welding onto the mulcher body required.
Option 2Add the Factory C4 Bolt-On Bracket and C4 PATS(D) Hardened Pin Kit
Pair with our matching C4 ATS(D) (6–10 Ton) Bolt-On Bracket and C4 PATS(D) Hardened Pin Kit (available as optional bolt-on mounting hardware machined to your excavator’s exact pin geometry).
Option 3Recommended Hydraulic Whip Kit
Add the C4 3M (9.8 ft) High-Pressure Hydraulic Hose Kit (TIDR2) to connect from the integrated Fluidbox manifold to your dipper-stick auxiliary pipes.
