Bush Hog® 1812 Flex-Wing Rotary Cutter

Light-Duty Pasture Flex-Wing

The 1812 Flex-Wing Rotary Cutter is designed for small tractors with a PTO horsepower of 50 to 75. The narrow cutting width of 12-feet makes this Flex-Wing ideal for rolling terrain where a wide rigid cutter will not perform as well. Grass, weeds, and brush up to 1 1/2-inch diameter are no match for the hardened parallel uplift blades. The narrow width is also ideal for orchards with prunings that must be cut into smaller pieces. The 1812 has maintenance friendly features, E-Z cleaning decks, high performance cutting and distribution, and it is built Bush Hog® tough for years of reliable service.
