WBM Brush Cutters are used in a variety of land clearing applications, primarily in forestry, road construction, and right-of-way maintenance. Our brush cutters are available in both Rotary Flail (ERF) and Rotary Cutter (ERC) configurations, for specific types of work.

WBM ROTARY MOWER FLAILS (ERF) are great for clearing smaller trees, tall grasses, and mowing heavy undergrowth and brush safely and easily. The replaceable rotary blades are made from heat-treated alloy steel which is stronger and longer lasting and will immediately swing back if they hit a solid object.
