The active tailings system is a major performance-enhancing feature of the S780, S785, and S790 models. It increases the capacity of the combine by taking care of tailings separately and makes the overall setup and adjustment easier. The net result is more performance and better grain quality with lower losses, as well as improved straw quality and reduced fuel consumption.
A mini threshing drum with real rasp bars and concave separate kernels still sitting in ears. Like the rest of the threshing system, this is designed to be gentle to avoid grain damage. The concave itself has two settings controlled by a spring lever for easy switching between corn and small grain crops.
The material is returned to the top of the chaffer by an auger. The opening at the bottom of the auger is triangular so material is spread evenly instead of it dropping in one spot. This helps avoid any potential overload of the cleaning system.
The system acts as a re-thresher which takes care of the tailings. This allows the concave to be opened wider which lowers both the power requirement and fuel consumption. At the same time, it has the added benefit of improving straw quality as the crop is not so compressed between the concave and the rotor. The reduction in tailings also allows the bottom sieve to be opened further, which increases capacity even more.
Depending on the gradient of the slope, Active Terrain Adjustment automatically adjusts all the important cleaning shoe settings and not just one: fan speed plus chaffer and sieve openings. It also takes into account the type of crop that is being harvested. For instance, rape seed is particularly sensitive to fan speed changes, so the system adjusts the chaffer and sieve settings first before adjusting the fan speed, whereas corn isn’t as sensitive to wind speed.
Active Terrain Adjustment results in consistently low grain losses on rolling terrain. It also reduces the amount of tailings and delivers cleaner grain to the tank. Possibly what’s most important of all, it takes the pressure off the operator to make constant adjustments and frees them up to focus on the harvest operation.
ActiveYield™ management is another automated John Deere innovation that saves time and improves harvesting performance. Now you no longer have to carry out time-consuming manual calibrations and double-weighing of trailers.
Three sensors inside the tank automatically measure the change in weight as the grain tank fills. The system compares the measurement with those of the yield and moisture sensors to calibrate the yield sensor on a permanent basis. The biggest advantage of the system is that it generates a calibration curve at various speeds and throughput levels with a number of calibration points which usually is not performed by operators in the field in a manual way.
What’s more, the system is designed to compensate for shifting grain when harvesting on slopes or if the operator performs a full stop. It even compensates for wear and tear of the elevator chain over several harvest seasons. It’s attention to detail like this that gives you the confidence to rely on the results year after year.
ActiveYield transforms the accuracy of yield mapping, as today 96 percent of customers only complete a single point or perform no calibration at all - only 4 percent complete the recommended multi-point calibration. This improves the accuracy of precision farming as it allows better control of inputs for variable rate seeding, fertiliser application, and crop care.
Now there’s no need to interrupt the harvesting chain for regular weighing in different crops and conditions.
Plus, you don’t have to worry if there’s no weight bridge within close proximity.
You’ll find the S700 Combines easier to operate the way you want it to. All the controls are integrated in one place. You won’t find yourself looking around the cab for different displays or reaching for out-of-the-way switches. Everything is logically grouped in one place. The Generation 4 display has been completely redesigned with the same, easy-to-use navigational features as a smartphone. Swipe to move from screen to screen, select apps you want to run, and customise screen layouts to suit the way you want to work. We’ve also rethought the navigation process, reducing the number of clicks to get you to where you need to be.
The ergonomic design of the CommandPRO™ hydro handle brings the same seamless experience as multifunction game controllers. Now you can control all the main functions from your hand. What’s more, you can personalise it like never before with seven programmable buttons.
And, best of all, you can switch between screens on the display by turning a wheel on the hydro handle – no need to take the hand off in critical situations when you have to have manual control (e.g., in down crop or while cutting the headland).
When they were designing the CommandPRO hydro handle control, our engineers looked at every hand-held controller from game players to aircraft. We listened to our customers’ demands as well. They wanted more programmable features to customize their harvesting. The result is over 30 percent more functions than any other combine controller.
As soon as your hand grips the CommandPRO hydro handle, you know this is very different from any other machine you have operated. It fits like a glove. The different buttons are in the perfect position. Even the scrolling wheel at the back is comfortable to the touch. It all feels so completely natural. You can imagine closing your eyes and being able to operate it perfectly. Man and machine working in harmony.
Choose the way you want to work: 600X header extension/retraction, 700D belt speed, grain tank cover opening, unloading auger folding, chopping spread direction, feederhouse tilt, and much, much more.
Individual buttons can be programmed via the touch screen on the Gen 4 CommandCenter™ 4600 Display.
If you have different operators, they will love the fact that they can all store their own individual settings for the CommandPRO hydro handle and display using the time-saving setup control feature.

If needed, we grab spare parts directly from the assembly line in our factories, even on the weekend.
5.2 m² of sieve area makes this one of the largest cleaning shoes on the market. Crop stays on the sieves for longer, maximizing cleaning time and minimizing losses.
The completely redesigned fan delivers up to 740 m³ of air per minute and was designed to evenly distribute the air over the entire width. Excessive suction on the side is minimized through targeted sealing of the openings, while more air is taken in through air ducts in the middle.
The large air volume paired with the new air flow and the large sieve area makes additional slope compensating features obsolete.
More effective two-stage pre-cleaner
An additional raised front chaffer is a unique feature of the Dyna-Flo Plus. This helps thin the crop mat and distribute it across both the front and rear of the cleaning shoe. It also cleans up to 40 percent of the free grain before it reaches the main chaffer.
Easily optimized cleaning system
We’ve completely redesigned the cleaning system so it’s less sensitive to operator adjustment. This means the operator doesn’t have to constantly make adjustments in changing crop conditions. No pre-chaffer adjustments are required at all, and it’s much easier to optimize the fan.
The self-cleaning conveyor augers ensure active crop flow on slopes and under tough harvest conditions. So even if you are harvesting on hillsides or in wet and sticky conditions (e.g. rape seed or corn), you can be sure that the cleaning shoe is evenly loaded.
Small improvements in grain yields bring big increases in profits. That’s why John Deere offers a comprehensive range of headers so you can find the perfect match for your crops and your combine. Choose from traditional auger designs (600R, 600F, or 600X) to active crop feeding with belts (700PF or 700D) in a wide range of widths up to 12.2 m.
More than 650,000 600R headers have been built, making it a proven and field-tested combine header. It has many premium features, including stainless-steel feed plates, a large-diameter auger, and a linear knife drive. The 600F features a flexible cutterbar which lets you drive faster and cut cleaner on uneven ground and helps reduce losses in down or tangled crops. A 600R or 600F with rape seed attachment has the lowest amount of losses during rape harvest due to the longest distance from auger to the knife.
The 600X is the ultimate header if you’re harvesting a variety of crops. It has an unbeatable conversion time of under 3 minutes without the need for any tools. Featuring the longest table on the market of variable headers, you won’t lose a lot of grain either. It also has the longest adjustable table length of 800 mm, so you can respond to changing conditions from the comfort of the cab.
The 700PF features an active transport, head-first crop flow process, which results in a very constant material flow so the combine can run at close to its maximum capacity. This makes it ideal for short-stalked grains or laid and long-growing crops as the feed auger only captures cut material. Conversion to rape seed is fast and simple. The 700PF headers with its 760-mm diameter augers are the perfect match for the S-Series in special conditions like down crop, tall rape seed, or short spring barley.
The 700D header features head-first active crop feeding with a belt instead of an auger. This design does not mix the crop like an auger-driven header and is well matched to S-Series rotor combines where the smooth feeding results in better threshing and separation. The cutting angle is hydraulically adjustable, and you can set your stubble height as low as 38 mm for gathering low or down crops. A rape seed attachment is also available.
Our corn headers are made in Germany by Geringhoff. Available in a wide range of widths and row spacings to match your combine’s capacity, they can run at high ground speeds even in down crop. Designed for minimal maintenance, the secret to their legendary durability is the precision-engineered aluminium main drives, row-unit gearboxes, and the CENTAFLEX® couplings which eliminates stress on the bearings and drive mechanism of each row unit.
CENTAFLEX is a trademark of CENTA Antriebe Kirschey GmbH.
The single rotor of the S-Series gives you a clear advantage over other, more traditional and hybrid systems. Instead of splitting the crop flow up into two streams, it keeps a single crop flow which consumes less power.
This is because the large diameter of the rotor generates higher inertia than smaller rotors. The rotor also has a much wider cross-sectional area for threshing than a tangential threshing system. This promotes an easy transition from tangential to the axial crop flow. The even crop flow means even threshing, separation, and chopping. The result is better straw and grain quality.
It doesn’t matter if you’re harvesting large areas of a single crop or moving from crop to crop, the S-Series offers true, multi-crop capability. Tested in 36 different crops, you can customise every single component from the header through to the rotor and residue management system. Crop conversion is fast and easy with excellent access to the rotor.
The 270-degree feeding concept is unique to John Deere. It ensures a smooth transition from a tangential crop flow from the beater to an axial crop flow for the rotor. More space in the front of the rotor makes this transition easier and less power consuming - power which can be put to better use for more effective threshing.
The thickness of the straw mat gradually reduces as it passes over the conical threshing area several times. In the front part of the cone, the easiest-to-thresh grain is removed through gentle and efficient crop-on-crop threshing. In the rear part, the remaining crop is separated. The overall effect is very gentle crop-on-crop threshing for the best possible grain quality and the highest power efficiency.
This maintains consistent concave clearance for better performance in high yield crops or when there is uneven feeding. It enables the concave to be set much wider for more crop-on-crop threshing.
The rear section of the rotor is predominantly where the separation takes place. Depending on the conditions, there’s a choice of two rotors: the TriStream™ rotor and the variable stream rotor. The TriStream rotor is recommended for lower yielding crops. The variable stream rotor is recommended for high yield, rice, or when crops are damp, wet, and green or in tough straw. For these conditions, the rotor has been designed with a more conical shape at the front, and the amount of rotations the crop performs can also be changed from inside the cab. This allows the operator to easily vary the threshing intensity depending on whether they are experiencing moist or dry conditions throughout the day. This way the straw quality can be improved as well.
The off-center rotor creates a pull-and-release effect. The crop is compressed as it passes the grates at the bottom of the rotor and is then released as it moves towards the top. This produces a separating effect which moves the grain to the outside of the crop flow where it is separated through the grates far more efficiently.
The rear section of the rotor is designed for maximum separation. That’s why the rotor has the biggest diameter at this point so it can generate the highest inertia. This delivers superior separation when compared to twin-rotor combines which have smaller diameter rotors. Separation is further assisted by the large fingers instead of threshing elements which loosen up the crop mat, making sure any trapped grain can escape from the straw instead of destroying the straw.
The operator can choose between two different crop-flow speed settings. In the standard position, the crop makes seven full rotations for higher grain separation. If the operator wants to optimize the straw quality or reduce chaff load on the straw in brittle conditions, he can switch to the advanced position. This exits the straw from the combine after just five rotations of the rotor.
On the road, the ProDrive™ transmission gives you transport speeds of up to 40 km/h so you’ll get to where you need to be faster. In the field, it delivers more torque and because of its infinitely-adjustable speed, you’ll cover more hectares in less time.
ProDrive transmission gives you precise control of your ground speed across two infinitely-variable speed ranges. You simply set one range for your typical harvesting speed and the other for transport. Then all you have to do is press the button for your chosen range and you simply control the combine’s speed within that range by pushing or pulling the joystick. There’s no need to stop to change gear.
ProDrive delivers 64 percent more torque across the speed range compared to a standard mechanical transmission. It also delivers 95 percent more torque at 6.5 km/h, an average harvesting speed, delivering even more performance.
Engine speed management automatically controls the engine’s rpm during road transport. This produces fuel savings of 10-20 percent.
The S-Series can be equipped with a range of transmissions offering transport speeds from 20 up to 40 km/h. The 40-km/h top speed greatly reduces transport time on the road so you can spend more time harvesting in the field.
The optional push-button shift transmission makes changing gear easy. Just push one of the three gear buttons and let the combine do the rest. Stopping is easy, too. The park brake is automatically engaged in the neutral position so there is no need to push a separate hand-brake pedal.
There’s a choice of up to three different chopper systems to suit your harvesting operation. Whatever you choose, you can rely on evenly-spread, fine-cut straw from the moment you start harvesting, or well-windrowed straw for quality bales.
All systems feature a discharge swap switch to change the offset for the direction of spread to compensate for wind direction. Our premium and intermediate systems are equipped with a 100 knife, extra-fine-cut chopper. This ensures the residue is quickly incorporated into the soil, releasing valuable nutrients for the next planting season.
The premium system is also a real time-saver. You can switch from chop to drop from the cab at the touch of a button. It proves a very useful feature at headlands or parts of the field which shall be treated differently when you can instantly switch from dropping to chopping.
Advanced PowerCast active spreader
The Advanced PowerCast active spreader is the perfect solution for even distribution of chopped straw and can be beneficial especially on cutting widths above 9 m. Positioned at the right angle, it is less sensitive to side winds than other spreaders. What’s more, the spreader accelerates the chopped straw as it passes through the vanes for a wider, more even spread up to 45 degrees.
Consistent grain quality and low loss levels in all conditions
Our revolutionary Integrated Combine Adjustment 2 (ICA2) automatically guarantees consistent output of the harvesting process whatever the conditions. Eliminating the need for regular manual adjustments, it gives operators the confidence their combine is operating as efficiently as possible.
Independent tests* have shown that the utilization of the installed combine capacity by the operator can vary by up to 20 percent. ICA2 takes away that uncertainty, giving you optimum performance hour after hour and day after day. What differentiates ICA2 from other systems is it controls both the threshing and cleaning systems, so you have complete control of the harvesting process.
Digital cameras located in the clean grain and tailings elevators continuously measure the amount of broken kernels and dirt, making real-time automatic adjustments to maintain the pre-set levels with no operator input required.
