2026 Bush Hog 5115

Bush Hog® 5115 Flex-Wing Rotary Cutter
Building upon the success of our legendary Heavy-Duty Flex-Wing lineup, the New 5115 Flex-Wing is built for the harshest cutting conditions. Designed to cut heavy grasses and brush up to 5” in diameter, these New 15’ Flex-Wings are serious machines for serious users. Perfectly at home maintaining rights-of-way and roadsides or long days clipping the back “400”, these cutters get the job done in any environment, day in and day out. New performance and convenience features like seriously upgraded axles, EZ-change blade bolts, 3/4″ Uplift Blade Carriers, and EZ-adjust leveling rods make your life easier and worry-free.
