Active Float Systems

The D2 gets instant float response with MacDon's Active Float System. Integrated but independent of the combine's auto header height control, this simple mechanical system supports up to 97% of the header's weight, allowing the D2 to float over ground fluctuations effortlessly. In addition, this instant float response lets the D2 cut close to the ground without pushing dirt, delivering a clean, close, even cut every time.

ClearCut™ High-Speed Cutting System

MacDon's ClearCut™ High-Speed Cutting System delivers clean cutting at up to 30% faster speeds*. This high-speed system is delivered with two unique knife guards, more power from MacDon's improved knife drive and over 25% more cutting surface from an increased knife and guard geometry. Altogether, these improvements allow the D2 to provide a smooth, clean, even cut every time.


ClearCut™ Pointed Knife Guards are multi-purpose knife guards designed to glide along the surface at high cutting speeds for a clean, even cut every time.

ClearCut™ PlugFree™ Knife Guards
This guard design gets the knife as close to the ground as possible while still protecting the blade from damaging debris in the field. ClearCut™ PlugFree Knife Guards resist plugging even in the nastiest conditions providing the closest, cleanest possible shave of the ground.


MacDon ClearCut™ knife sections feature over 25% more cutting surface thanks to a longer blade and improved geometry. So what does that mean for you? It means faster, cleaner cut quality at higher ground speeds.

Stay Sharp!
Another great advantage of this new cutting system is the redesigned hardware. Fitted bolts make in-field knife section replacement quick and easy.

ClearCut™ High-Speed Knife Drive

MacDon's improved knife drive satisfies your need for speed, providing more torque to power through the most challenging cutting conditions. Featuring a larger output shaft, a flywheel for smooth operation, and a direct hydraulic drive, it's the heart of MacDon's ClearCut™ High-Speed Cutting System.

A Consistently Close Shave

On the D2, MacDon's low-profile cutterbar improves on an already good thing; the knife's distance to the draper is shorter, meaning less chance of seed loss at the cutterbar. In addition, in-cab header tilt control adjusts the knife angle to match any harvest condition, and the ultra-smooth ground-facing surface of the cutterbar helps it glide along the ground for a smooth close shave every time.

Super-Sized Capacity

With today's modern combines, it's all about more capacity, and with the D2, you get up to 20%* more of it. This serious capacity boost comes from an ultra-deep deck featuring 50-inch deep drapers. These huge drapers perform with ease, cleanly laying down the biggest bushiest high-volume crops, keeping those big combines running smoothly with consistent heads-first feeding. This deeper draper also provides improved cutterbar visibility from the combine.

Amazing Reel Performance

The unique movement of the D2 reel picks up and gently places crop onto the drapers. This patented reel features a uniquely shaped cam that allows the fingers to get underneath lodged crop and pick it up before cutting. Aluminum reel ends and sectors help reduce overall weight and improve efficiency. The D2 header and reel are highly adjustable right from the cab for optimal performance. Header tilt control adjusting the draper and knife angle, and fore-aft reel positioning lets you set up for the most challenging real-world harvesting conditions.

ShatterGuard Reel Positioning

Using MacDon's Set-It-Right Multi-Tool, this quick, simple adjustment to the reel comes standard on all D2 models. ShatterGuard Reel Positioning is designed for tall brittle bushy crops like canola and oilseed rape. This adjustment sets the reel further back on the header, preventing shatter on the ground and keeping the crop on the drapers where you want it.

Heads-First Active Crop Flow

Once the crop gets on the drapers, MacDon's Active Crop Flow takes over, swiftly moving the crop heads-first down the side drapers and into the combine's feeder house. Now standard on the D2, the in-cab side draper speed control allows on-the-go adjustment. Heads-first feeding promotes peak combine efficiency by improving threshing action, creating better straw distribution, and providing an overall more productive fuel-saving harvest. What's more, MacDon's Active Crop Flow is more efficient in damp and moist conditions, meaning you can start earlier and work later into the evening.

FeedMax™ Crop Feeding System

Big, small, new, old, the FeedMax™ Crop Feeding System has an aggressive feeding action and can be custom configured to match any combine's performance. Featuring combine-tailored speed control and customizable auger flighting to fit any combine's feeder house opening, the FeedMax Crop Feeding System upgrades and optimizes any combine's performance.

Full-Length Upper Cross Auger

A performance option worth considering for anyone harvesting big bushy, high-volume crops, like canola, oilseed rape, peas, and mustard, is the Upper Cross Auger. The auger keeps bushy crops on the draper as they move to the center of the header, where twin pitch flighting actively and aggressively drives the crop down onto the feed auger. This option runs the entire length of the header and is available on all sizes of the D2.

Any Combine

The D2 fits all major brand combines* with a completion package that integrates seamlessly with your combine for the best possible user experience. This multi-brand compatibility and interchangeability mean your investment will hold its value when you decide to update.


The Set-It-Right Multi-Tool is all you need to get the D2 dialed in for harvesting success. Conveniently stored onboard the header, this one tool gets the D2 ready for your unique harvesting conditions.

The Set-It-Right Multi-Tool Lets You Make The Following Adjustments:
Set the ShatterGuard reel positioning.
Adjust the reel finger positioning and reel drive chain tension.
Add and remove end divider cones.


You'll be ready to go as soon as the crop is with the D2's easy adjustments. Including easy access to the reel drive chain tensioner, just flip off the cover and use the Set-It-Right Multi-Tool to adjust. And now standard for the D2, in-cab on-the-go side draper speed control.

Quick Latch End Divider System

MacDon's Quick Latch End Divider System lets you hook and connect your divider in one move, whether you're using standard rod dividers, rice dividers, or VertiBlade™ Vertical Knives. The standard divider rods store onboard, and an optional onboard divider cone storage is available.

EasyMove™ Transport*

MacDon's EasyMove™ Transport System makes it faster than ever to move your D2 Series Combine Header from field to field. This Performance Option is entirely self-contained on the header and allows transport at speeds up to 32 km/h (20 mph)**. Machines equipped with this option can also use the transport wheels in-field to stabilize the header.

Aluminum Components

From a glance, the most noticeable design cue on the D2 is the addition of aluminum components. Aluminum features include reel endshields, reel sectors, and backsheets. But these components aren't just for looking good; they help reduce the overall weight of the header, improving efficiency without compromising strength.


MacDon has always ensured reliability by engineering rock-solid products, and the D2 carries that tradition forward. The D2 boasts a new frame featuring a super structured five-sided back tube. This solid backbone is ready to handle the up to 20% increased capacity* of the ultra-deep 50-inch+ draper deck+.


MacDon added a bunch of little extras onto each D2 to keep the crop moving in the right direction, into the combine and onto your bottom line.

The Clean Sweep Crop Keeper System Includes:
Angled reel fingers and tines on the reel ends.
Reel endshield crop paddles.
Reel endshield crop deflectors.
Inner endshield crop deflector fingers.
