The 3112 is a versatile, heavy-duty 12′ Flex-Wing that continues the pedigree of our larger, commercial Flex-Wings. Taking design cues from our 4115, the 3112 is built to perform in a variety of applications from routine pasture and orchard mowing to roadside maintenance. Designed to cut heavy grasses and brush up to 3 ½” in diameter, these mowers get the job done in virtually any environment. It is equipped with the latest performance and convenience features like durable, stoutly-braced 10ga Decks, ¼” Sidebands, 7ga Round Blade Pans, ½” x 4” blades with 8” overlap to ensure impeccable cut quality, dual EZ-adjust leveling rods, and ½” thick replaceable cast wing skids. Each axle arm contains custom shock absorbing isolators to glide over obstacles, while significantly reducing shock loads for an improvement you can feel in the tractor seat. 130HP gearboxes are integrated into heavily gusseted stands that resist torsional forces and impacts. Other standard equipment includes features like:
o Adjustable Driveline Assist to take the load off the heavy Cat 6 CV driveline while attaching and removing from the tractor PTO
o Perma-Level+ Hitch for easier drawbar hookups
o Increased tongue transport height range to fit virtually any drawbar height
o Color-coded aluminum hydraulic hose handles to reduce hand-slipping and improve ergonomics
The 3112 comes standard with a 540 CV Cat 6 Driveline, Cat 4 Wing Drivelines, Center Dual Axles, and 2 hydraulic hoses. It is available with or without Deck Rings, Single or Dual Wing Axles, and Single or Double Row Chains. Like all of our cutters, the New 3112 12’ Flex-Wing is made with pride in the USA and comes with the a 10-Year Gearbox Limited Warranty.
