Description
The Extreme Duty Solution
The Stinger F5 is not just a brush cutter; it is a dedicated Forestry Disc Mulcher. Engineered for commercial land clearing, it features a massive 1-inch thick blade carrier equipped with both steel blades and carbide mining teeth to grind 8-inch trees down to the soil.
The Power Source
Driven by a high-torque Radial Piston Motor (Direct Drive), the F5 eliminates the gearbox entirely. This "bi-directional" motor allows you to cut in both directions and creates the massive inertia needed to mulch hardwoods without stalling.
