Blue Diamond® Mini Excavator Brush Cutters are a natural extension of our skid steer brush cutter line. The extremely rugged direct drive system has a large flywheel that stores energy and keeps the blades cutting even in difficult conditions. These brush cutters use a 3 blade system with straight AR400 double edged blades. These rugged brush cutters have proven to be top performers paired with a wide range of mini excavators.
