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. 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 7” (178 mm) of vertical float independent of the combine feeder house. Best of all, this is a simple, mechanical system with 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.

Combine Interchangeability

Thanks to the FM100, MacDon Draper Headers are designed to fit all major brand combines with an easy-to-install completion package. This multi-brand compatibility and interchangeability mean your investment will hold its value until it's time to update your header.

The MacDon FeedMacX

The MacDon FeedMacXTM
MacDon's FeedMacXTM system is designed to be custom configured to match any combine's performance capabilities, providing serious capacity, optimized feeding, and incredible productivity. FeedMacXTM components are built smart and tough to provide the performance and reliability MacDon is trusted for. Here's how it works:

The heart of the FeedMacXTM crop feeding system is the RTD (Retractable Tine Drum), featuring combine-tailored speeds, feeding configuration and aggressive action, resulting in up to 20% more capacity over the previous model. In-feed speed is tailored to match that of your specific combine's feeder chain. Bolt-on components make it possible to configure the auger flighting and number of finger tines to match the combine's feeder house opening. The finger tines are longer and more aggressive and feature adjustable timing to match the crop volume of any harvest condition. Altogether, the FeedMacXTM system works to optimize the performance of any combine in any crop.

The strength and reliability of the FM100’s RTD come from smart innovations and heavy-duty internal components, like the tine shafts that are 25% thicker than the previous model and an all-new reversing clutch that provides positive engagement in either direction. The new finger design protects both the header and the combine from foreign objects. Reconfigured and upgraded, the chain drive tension is externally adjustable and incorporates a positive stop to retain its setting and alignment. 

High Capacity Hydraulics

MacDon's new hydraulic system features individual fully filtered circuits for the knife drive, side drapers, and feed draper. These individual circuits provide increased side draper speed, along with greater capacity and reliability. The 1 Series hydraulics make it possible for an optional in-cab side draper speed control, allowing on-the-go adjustment.

Amazing Reel Performance

Unlike other headers, the movement of our heavy-duty reel picks up and gently places crop onto the drapers. The reel features
a uniquely shaped cam, which allows the fingers to get underneath lodged crop and 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.

Active Crop Flow

MacDon's Active Crop Flow gently places crop on the side drapers heads-first and swiftly moves it onto the feed draper, where it's scooped up into the combine's feeder house. Heads-first feeding promotes peak combine efficiency by saving fuel, improving threshing action, creating a better straw distribution, and allowing for a more productive harvest overall. Because this harvesting method is more efficient in damp and moist conditions, you can start earlier and work later into the evening. 

Part of MacDon's FeedMacXTM system, the side draper speed is increased up to 60% to optimize combine capacity, and an optional in-cab side draper speed control allows on-the-go adjustment. 

Multi-Crop Harvesting Solution

MacDon’s D1 and FD1 Series headers are true multi-crop harvesting machines able to take down cereals, oilseeds, beans, and just about any crop in any condition. The FD1 FlexDraper® switches easily from flex to a solid frame with the quick flip of a lever, giving you the ultimate flexibility to move from one crop type to another. Any crop, any condition, MacDon Drapers are the ultimate performance upgrade for your combine.

A Consistently Close Shave

MacDon’s patented C-shaped, low-profile cutterbar design allows ground level cutting for the most consistently close shave of your fields. Featuring a heavy-duty knife drive and in-cab knife angle control, this cutting system allows you to match any harvest conditions. The ultra-smooth ground-facing surface of our cutterbar helps our headers glide along the ground for a smooth close cut every time. 

Aggressive Upper Cross Auger

The optional Upper Cross Auger helps to move heavy, bushy, high-volume crops, like canola and peas, to the center of the header for smooth feeding. Featuring twin pitch flighting at the center of the auger to aggressively drive crop down and into the Retracting Tine Drum (RTD) of MacDon's FeedMacXTM system. Available for all header sizes,  the upper cross auger is attached in front of the back tube and features a shut-off valve to disengage the drive when not required. 

Self-Contained Transport

Our Slow Speed Transport package allows you to tow your D1 and FD1 Series Headers up to 20 mph (32 km/h)*. This option also adds the advantage of spring-loaded stabilizer wheels.
