The IronCraft 3520 Flex-Wing Cutter is a heavy-duty 20-foot rotary cutter built for large fields, pastures, roadsides, right-of-ways, and other demanding mowing applications. With a 240-inch working width and the ability to cut material up to 4 inches in diameter, the 3520 provides the coverage and cutting capacity needed for large-scale vegetation management.

Designed for tractors with a minimum of 80 PTO horsepower, the 3520 features a flex-wing design that allows the cutter to follow uneven terrain. The wings provide up to 22° of downward flex and 100° of upward flex, while the self-leveling swivel-pivot hitch and spring suspension help the cutter follow changing ground conditions.

The heavy-duty construction includes a 10-gauge center deck, 7-gauge wing decks, 1/4" x 13-1/2" side bands, 1/2" x 4" uplift blades, replaceable skid shoes, and slip-clutch driveline protection.

This 540 RPM IronCraft 3520 is equipped with chain guarding, eight 27" AirCraft tires, walking tandem axles, and a light kit.
