 Valley Tool Manufacturing Logo

The FHX66 Defender Skid Steer Forestry Drum Mulcher is a high-performance standard flow forestry mulcher attachment engineered to turn your skid steer or compact track loader into a powerful land clearing machine. Designed for fuel reduction, right-of-way clearing, and defensible space maintenance, this forestry drum mulcher delivers aggressive cutting power with lower hydraulic requirements—only 17 GPM needed.

With a cutting capacity of up to 10″ intermittently and 6″ continuous, the FHX66 Defender efficiently processes brush, vines, and trees while maintaining smooth, vibration-free operation thanks to True Shaft Technology and an electronically balanced cutter drum.

  • Quadco QUAD TOOTH® Cutter Knives – 2″ rotatable, four-position steel alloy teeth for long wear life

  • Hardox 400 Shielding – Wear-resistant liner for strength and durability

  • Goodyear Eagle Timed Belt – Self-aligning system increases torque and reduces maintenance

  • True Shaft Technology – Serviceable hubs and balanced drum for smooth operation

  • 12.75″ Cutter Drum – 2,000 RPM with ¾″ thick construction

  • Adjustable Brush/Tree Bumper – Directs material into cutting path
