Bush Hog® 5115 Flex-Wing Rotary Cutter

New Extreme-Duty 15' Flex-Wing

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. Our new and improved axles glide over obstacles, while significantly reducing shock loads for an improvement you can see and feel in the tractor seat. Heavily-braced, 1/4″ smooth-top decks shed debris and water for easier cleanup. Extreme-Duty gearbox stands are thicker, braced and gusseted to withstand the harshest cutting environments. Our Perma-Level+ Hitch has received additional reinforcements and quality of life features like rollover and clevis stops for easier tractor hookups. Standard equipment includes convenience features like EZ-lube drivelines, increased tongue transport height, and hydraulic hose handles to reduce hand-slipping and improve ergonomics. Then when not in use, the hoses can be safely stored in the holder on the tongue.

The New 5115 15’ Flex-Wing comes standard with distribution-improving Deck Rings and Double Row Chains for added safety. It can be configured with 540 or 1,000 PTO Driveline, Center Dual or Walking Tandem Axles, Wing Single, Dual, or Walking Tandem Axles, Laminated, Air-Filled, or Foam-Filled Tires, and 2 Hoses for simultaneous wing lift or 3 hoses for independent wing lift. And as with all Bush Hog® Rotary Cutters, the New 5115 Extreme-Duty Flex-Wing comes with the industry’s only 10-Year Gearbox Limited Warranty. To stand behind our product even further, the 5115 carries the industry’s first and only 3-Year Machine Limited Warranty. This cutter is built to last! That’s why our customers say, “If it doesn’t say Bush Hog®, it just won’t cut it.”
