IronCraft 3520 Flex-Wing Cutter Description
If you need to mow large areas, don’t waste your time with a small cutter. Spring for IronCraft’s widest flex-wing mower with a 20 ft cutting width. Designed for large tractors with 80 hp or more, the transport width is only 8 ft, making it easy to tow down the road, a path in the woods, or pass through your fence-gate.
You’ll not only cut 20 ft at a time, but cut down anything up to 4″ in diameter—that’s some serious clearing capability. And the 3520’s Spring Loaded Suspension System and Optional Walking Tandem Tailwheel Assemblies offer a stable, even cut, no matter how challenging the ground conditions. Three tire styles available—foam filled, “Aircraft” pneumatic, or laminated.
Available for 540 rpm or 1000 rpm PTO shafts.
Designed heavy duty with large 1″ internal leveling rods, 4″ wide blades, and larger replaceable skid shoes, and a clean, flat top design for easy maintenance and service.
