The Wide-Area Pasture Flex-Wing

The Bush Hog® 2120 Flex-Wing Rotary Cutter is designed to cut grass, weeds, and light brush up to 2” in diameter. The perfect cutter for maintaining large pastures, open parks, and airports, where clipping distribution is paramount for presenting a clean, manicured appearance. Fully-baffled decks increase directional air flow allowing the blades to guide clippings across the entire width of the cutter. EZ-clean decks, EZ-adjust leveling rods, EZ-lube drivelines, and multiple grease points, make maintaining the 2120 a snap. Invest in the 2120, and it will reward you with years of excellent performance and dependable service.
The 2120 comes standard with Distribution Baffles, along with your choice of Perma-Level or 2-5/8” Ball Hitch, 540 or 1,000RPM CV Input Drivelines, Center Dual or Walking Tandem Axles, Wing Single, Dual, or Walking Tandem Axles, 5 Tire Selections, and Single or Double Row Safety Chains.
