Clear brush and cut up to 3″ diameter trees efficiently with this 40″ excavator-mounted brush cutter, designed to deliver up to 35% faster blade speed than traditional 36″ mini-excavator cutters—without adding unnecessary weight.

This model is weight-optimized for 6,500 lb (3-ton) mini excavators and features a direct-drive Eaton® hydraulic motor, eliminating the need for a case drain while providing reliable, low-maintenance operation. The built-in relief valve protection helps safeguard the motor and drivetrain under demanding conditions.

The rounded flywheel design with (3) double-sided blades allows the cutter to bounce off stumps and obstacles instead of grabbing, improving durability and operator control. This unit is equipped with the optional two-sided chain curtains for added debris containment and optional mulching teeth for a finer finish.

A bolt-on mounting interface allows quick changes between hanger brackets, making this cutter adaptable to most excavator brands. Standard equipment includes 90″ hydraulic hoses, couplers, motor guard, and spindle guard, so it’s ready to work right out of the crate.
