With its heavily braced deck and triple spring suspension, the Blue Diamond® 15′ Flex-Wing Rotary Cutter is designed for heavy duty applications such as weeds, grass, and brush up to 4” diameter. Designed for use with tractors as small as 55 hp, the cutter has a 180” cutting width. The cutter uses three spindles with two free-swinging blades each to reduce the shock of hitting a stationary object. Slip clutches protect the gearboxes and driveline from damage. Standard equipment includes driveline shields, clutch shields, front and rear chain discharge shields, and a towing safety chain.
