This wing assembly helps to extend the wings of the EXT Plows from 8' to 10'. Quickly and easily expanding from 8 to 10 feet at the touch of a button, the BOSS EXT is equipped to clean up parking lots and wide open spaces. A true 10-foot width combined with pitched-forward wings lets the EXT take wide passes, carrying and moving more snow more efficiently. At 30 inches high with 9 vertical ribs, the EXT moves a high volume of snow with resilience, making it a versatile and flexible addition to your fleet.
