Bush Hog® 4110 Flex-Wing Rotary Cutter

New Heavy-Duty Right-of-Way Single Flex-Wing

Building upon the success of our legendary Heavy-Duty Flex-Wing lineup, the New 4110 Flex-Wing is built for the harshest roadside cutting conditions. Designed to cut heavy grasses and brush up to 4” in diameter, these New 10’ Flex-Wings are serious machines for serious users. Perfectly at home maintaining rights-of-way, levees, and roadsides, 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. Our new and improved axles glide over obstacles, while reducing shock loads for an improvement you can see and feel in the tractor seat. Heavily-braced, 7ga smooth-top decks shed debris and water for easier cleanup. Gearbox stand plates are thicker and gusseted for improved strength and durability. 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 slipping and improve ergonomics; then when not in use, the hoses can be safely stored in the holder on the tongue.

The New 4110 10’ Flex-Wing comes standard with Deck Rings and Double Row Chains for additional safety on roadsides. It also comes with your selection of 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 as with all Bush Hog® Rotary Cutters, the New 4110 Flex-Wing comes with the industry’s only 10-Year Gearbox Limited Warranty. Remember, “If it doesn’t say Bush Hog®, it just won’t cut it.”
