FHX66/GEAR/QT3000

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.
