Built Above and Beyond
No matter what dimension or weight our equipment might be, it is always built with a heavy-duty, all-day attitude. Always. Our line of 3-Point Hitch Booms raises your capabilities and efficiency every single day they’re in the field.

Using the right tool for the job is always the first rule of safety. By simply choosing the Diamond Rear Swing Flail, you are already working safer. In addition, the RSF has some heavy-duty safety thinking built right in.

flail knives are engineered to be far less likely to propel rocks and other nastiness.

No more road crews risking their lives to trim around guardrail posts and signs. Simply drive in and straight line parallel to the rail as the deck height self-adjusts to the terrain and automatically cycles around the post for minimal operator fatigue. mowing speed is approximately 1 mph. (How many miles can you weed-whack in an hour?) This is an innovation that makes sense at every turn.
