The Flail Mower, also known as the BladeRunner, is the heaviest-duty mowing attachment in the BCS fleet. Capable of mowing in the toughest conditions, the Flail Mower has vertically rotating 'Y' blades that pulverize plant material into a fine pulp that is evenly spread across the mowing width. The Flail Mower's front bulkhead is designed for lifting itself depending on the flow of material to be worked, which can be thick brush, vines and saplings. Like the Brush Mower, it can mow anything it can bend, including saplings. A convenient control handle sets the cutting height from ½'' to 4'', and retractable caster wheels allow for easier handling and transport. The mower rides on special side-mounted skids made of boron steel.
