Speed, precision, performance, that's exactly what you get with the MacDon M1170 Windrower and R1 Series Disc Header. Our patented CrossFlexTM suspension and low-profile, forward-mounted cutting discs help deliver a smooth, clean cut at in-field speeds of up to 14 mph (22.5 km/h).

The two-stage controls allow for faster and more precise positioning of the header lift, and customizable One-Touch-Return buttons can be programmed to control the header's height, tilt, and cutting speed. With all this and more, it's easy to see why the M1170 Windrower and R1 Series Disc Header are a knockout combo.
