Bush Hog® 4115 Flex-Wing Rotary Cutter

Designed to cut heavy grasses and brush up to 4” 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, and EZ-adjust leveling rods make your life easier and worry-free.
