RockHound Attachments has introduced the new 40EXTreme, designed and built for the brush-cutting contractor. The 40EXTreme is over 1,300 lb and designed for maximum professional brush-clearing durability. It was built with 250-hp components, such as the cutter drum, mounting ears that are 5/8 in. thick, end plates and an abrasion-resistant plate shroud. The biggest innovation is the new Extreme hammer knife configuration. A BrushHound exclusive, this triple-knife design gives you the best of both the 2-lb knife and swinging hammer combined. The 40EXTreme cuts quicker, mulches heavy vegetation into even smaller pieces than the double-knife design and has up to a 40% extended knife life.
