Close Reel-to-cutterbar relationship
The MacDon FD1 FlexDraper^® features a fixed reel-to-cutterbar relationship. A small gap between the reel fingers and the cutterbar is maintained at all times, even at extreme flex, ensuring smooth, consistent, heads-first feeding of the crop over the entire width of the FlexDraper^®. 

Active Float System
MacDon's Active Float System reacts instantly to changing ground conditions. This immediate float response means you can cut extremely close to the ground without pushing soil. Two sets of coil springs on the FM100 Float Module support up to 97% of the header weight. The instant float response provides 4.8 degrees of lateral float and 178 mm (7”) of vertical float, independent of the combine feeder house. Best of all, this is a simple reliable mechanical system requiring only one sensor, so things won't break down when your harvest is on the line. MacDon’s Active Float System keeps our headers true-to-the-ground for a clean, even cut every time.

Reel Performance
Unlike other headers, the movement of our heavy-duty reel picks up and gently places crop onto the drapers. The FD1 reel features 4" finger spacing and a uniquely shaped cam, which allows the fingers to get underneath lodged and low-podding crop to pick it up before it's cut. Along with the header tilt control, which hydraulically angles the knife from the cab and fore-aft reel positioning, our headers can be adjusted for the toughest harvesting challenges.

True Ground following
The MacDon FD1 FlexDraper^® is a floating, three-section flexible header with a split reel. This allows the entire header frame, cutterbar, and reel to follow ground contours as a unit, flexing up to 254 mm (10") on either end, while maintaining a close reel-to-cutterbar relationship. This unique three-section design lets the FD1 FlexDraper® deliver smooth, consistent, head-first feeding to the combine, even at extreme flex.
