The Ground Shark™ Extreme Duty High Flow and new Hi/Low Flow Brush Cutters are designed for clearing medium to heavy density brush and hardwoods up to 10” diameter (30-45 GPM models) from wooded acreage, road rightof-ways and pipeline maintenance. The exclusive, patented retractable forward cutting shield moves up and back to expose the entire cutting edge of each blade as it comes in contact with a tree or heavy brush. This Bradco pioneered feature provides additional safety protection for the operator and worksite while greatly minimizing flying debris.
