Imitated but never duplicated
Featuring MacDon Flex-Float Technology®, FD1 Series FlexDrapers continue to advance harvesting innovation. The flex advantage comes from a fixed reel-to-cutterbar relationship, which maintains a small gap between the reel fingers and cutterbar, while the Active Float System allows for instant lateral and vertical float response over rolling and uneven terrain. The result of our Flex-Float Technology is smooth, consistent, heads-first feeding that significantly boosts combine productivity.

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.

Take FlexDraper® Performance Over the Top!
The ContourBuddyTM Performance Option is a simple mechanical system that uses strategically placed wheels under the FlexDraper. This design takes full advantage of the FlexDraper’s Flex/Float system mirroring the contours of the field while cutting up to 10 inches from the ground surface. Using ContourBuddy sets you up for next year’s seeding with a consistent even stubble height.

CONSISTENT STUBBLE HEIGHT ON ROLLING TERRAIN
ContourBuddy provides FlexDraper owners the technology to use the Flex/Float and Auto Header Height systems of the header to cut ground contour mirroring stubble heights between 4 inches (100 mm) and 10 inches (250 mm) from the ground surface.*(*true range varies slightly depending on combine type)

HOW IT WORKS
ContourBuddy uses wheels in four strategically placed locations, one on each end of the header and two sets
at the hinge points of the header’s flex. These wheels allow the FlexDraper’s Flex/Float technology to work while cutting
up to 10 inches from the surface while mirroring the ground contours.
