Higher threshing performance in tough conditions: The unique multi-drum threshing system with the crops flowing above the rear beater ensures a consistent crop flow without sharp bends or abrupt changes in direction. This guarantees excellent grain and straw quality and reduces power requirements.
The Tangential Plus Separator with 800 mm is one of the biggest on the market which offers more separation. With for the season 19 we designed the Tangential Plus concave underneath with up to 10% more performance.
The new John Deere Tracks keep you harvesting also when it comes to unstable ground and muddy conditions thanks to our unique new design. The extra large footprint with 30% larger footprint, reduces soil compaction. The new suspension system ensures 20% more comfort and a smoother ride.
A more efficient and relaxing way to work
Welcome to one of the most productive and comfortable places to work. With just 71 dB(A), the Premium cab version is one of the quietest in the industry. The T-Series’ spacious cab has a total size of 3.3 m³ (116.5 cu ft). It’s loaded with a host of smart details to help you perform at your best while keeping you relaxed, even during long working days and under the toughest of harvesting conditions. Thanks to the tinted glass around the entire cab, the slim- line cornerpost, and highly ergonomic control elements, you always have a clear view and are always in control.
A spacious cab with 5.9 m² (63.5 sq ft) of glass ensures a great view
The cab was designed specifically for combines; with a total of 5.9 m² (63.5 sq ft) of glass in the front and to the sides, it provides an excellent view everywhere you need it, such as when unloading the grain tank.
Optional air-suspended leather seat is available
For extra comfort, a leather air suspension seat is available as an option. Even better, the hard-wearing leather seat is air cooled, making even the longest of harvesting days easier. A leather-covered steering wheel providing a solid grip is also available.
A large refrigerator with 37-L (1.3-cu ft) storage capacity
John Deere defines comfort down to the detail, even when it comes to the refrigerator. There is plenty of space with an impressive 37-L (1.3-cu ft) interior, perfect for storing large bottles in an upright position or a larger lunch box for a long working day. The fridge can actively cool down warm liquids and keep them cold during extended hours.
Unique multi-drum threshing system with crops flowing above the rear beater
The unique multi-drum threshing system with the crops flowing above the rear beater ensures a consistent crop flow without sharp bends or abrupt changes in direction. This guarantees excellent grain and straw quality and reduces power requirements.
The 660-mm (26-in.) cylinder guarantees gentle threshing with well-preserved straw and reduced grain damage due to its large-diameter 10 rasp bar design, high oscillating weight, and the fact that John Deere combines thresh more by rubbing rather than beating. The open cylinder directs the dust into the machine and doesn’t force it out of the feederhouse, giving you a better view of the header.
Quick-engage rasp bar for up to 10 percent more performance in barley
The quick-engage rasp bar ensures even more intensive threshing. The booster bar has been placed closer to the cylinder to produce more friction. It's especially effective for threshing damp or difficult-to-thresh crops such as barley or bearded wheat. Even better, it doesn't waste valuable separation surface as the booster bar doesn't minimise your concave surface. This makes it a real alternative to the existing de-awning plates and should be the first choice in difficult threshing conditions.
Up to 4 m² (43 sq ft) of active separation area for highest throughput
For the T-Series Combines, John Deere has further optimised this proven concept: the wrap angle of the threshing cylinder has been extended by 8 degrees, and the separator has been increased from 660 mm to 800 mm (26 in. to 31.5 in.) – one of the largest cylinders on the market. Despite increasing the overshot beater to 500 mm (19.7 in.), the angles and interconnection points between the cylinders were kept in order to guarantee the same optimum crop flow as before.
This means the entire threshing and separation area (the active separation area) has been increased by 18 percent. On the 6-walker combine, this is equal to 4 m² (43 sq ft), one of the largest threshing and separation areas on the market. Compare them yourself: a John Deere 5-walker with an active separation area of 3.3 m² (35.5 sq ft) offers more separation area than most 6-walker models on the market – and this with a smaller transport width!

Tangential Plus concave with up to 10 percent more performance
A patented rear separator grate is available for the T-Series Combines, which features 14 percent more openings in the separator grid and a fully rounded profile on the wires and cross bars. This creates a better separation effect thanks to a faster, unobstructed crop flow over the grid with a thinner layer of material thickness to boost the separation of kernels trapped in straw.
Two key points emerged from analysing the crop flow inside the combine under different conditions with different straw volumes. The centrifugal force together with the size of the grids are key points for achieving high separation, and a smooth separation grid surface ensures good straw quality and high material speed.
Modified seven-step walker with extended area
The discharge beater with a 400-mm (15.75-in.) cylinder separates the grain from the straw once again and guides the harvested crop reliably onto the extensive walkers.
The seven-step walker has been extended and its geometry has been modified so that any remaining grains can be separated from the straw. No extra technology is required, even in uphill or downhill situations, thanks to the large dimensions of the threshing and separating components.
One of the largest cleaning shoe areas on the market with 6.3 m² (67.8 sq ft)
How can you considerably enlarge the sieve surface without adding any weight and reducing the oscillating weight? The developers at John Deere found a brilliant answer to that question back in 2015. The result: 41 percent more sieve surface and less weight at the same time.
This was possible through an innovative, lightweight design and an aluminium structure resulting in reduced weight, which reduces peak engine loads and cuts down on vibration. This means the harvested crop stays on the sieves longer, maximising cleaning time and minimising losses.
The T-Series is designed for the highest capacity. The 5-walker combine has a total sieve area of 5.2 m² (56 sq ft) and the 6-walker has 6.3 m² (67.8 sq ft), according to ISO Norm 6689: 1997.
11,000-L (312-bu) grain tank with up to 125-L/sec (3.55-bu/sec) unloading capacity
The T-Series Combines help you save valuable time, even with unloading. A great feature in this class, the 11,000-L (312-bu) capacity grain tank can be unloaded in record time: up to 125 L/sec (3.55 bu/sec). The large-diameter unloading auger turns with low rpm and is therefore gentle on grains. A special focus is also placed on the grain quality and making unloading on the go as easy as possible.
The electronic engine management provides up to 25 kW (34 hp) of extra performance during unloading while driving so you can continue harvesting with full power.
The optional wireless camera kit transmits a picture to the monitor of the tractor driving nearby.
Improved unloading on the go with Machine Sync
With John Deere Machine Sync, the combine operator can have the tractor with a trailer drive alongside the combine while unloading. Once in position, the combine operator can control the ground speed and steering of the tractor-trailer combination. Grain trailer operators can see the grain tank levels of several combines and can be called to empty the fullest tank. This saves time, diesel, and nerves, and minimizes soil compaction.
Boost your productivity with connectivity
John Deere is committed to setting new standards in connected agriculture because this offers tremendous potential to boost productivity, save valuable time, and lower costs.
John Deere has identified the best technologies currently available on the combine market and brought them together into attractive packages:
Maximise uptime with machine-to-office communication
Leveraging the machine-to-office connectivity your John Deere dealer can provide (with your permission) maximises machine uptime. For example, the dealer can remotely check machine health and identify potential issues before they actually stop you from working. With Remote Display Access (RDA), you or your dealer have a live connection from the office to the GreenStar™ 3 2630 Display on the combine to assist the operator with machine setup and operation without needing to drive out to the field.
The hub to all your data – MyJohnDeere.com
The Operations Center on MyJohnDeere.com is the hub for all your data. Store field locations, track the progress of your machines, assign work orders to your operators, view yield and moisture maps, and create, analyse, and share harvest reports with trusted advisors and customers. What’s more, you can access it from any internet-enabled device.
Achieve more with less effort
With John Deere’s satellite-based, hands-free AutoTrac system, every pass matches the full cutting width of your platform. This helps you save time and fuel and boost your combine performance – even at night, in dusty conditions, on hillside terrain, and even after long hours of operation. The automatic steering relieves your operators and allows them to concentrate on their yield. When working with multiple machines in a field, the AutoTrac guidance lines can be shared from one machine to another so that all combines can harvest at the full cutting width. They can also be shared with the tractor or grain trailer operator so the machines can drive exactly parallel to each other during unloading.
The AutoTrac RowSense™ system adds even more comfort and productivity to corn harvest. It merges global positioning system (GPS) based automatic steering and row guidance – leveraging row feelers on the header – to increase harvesting speed. When row feeler information is not available, such as in down crop situations, the GPS signal takes over.
ICA increases the performance of the combine
With ICA, you can increase the performance of your combine, minimise losses, avoid grain damage, and improve the quality of your straw. You can either optimise all parameters at the same time or focus on one in particular.
Standard on all models within the T-Series, Automatic Combine Adjust helps you effortlessly transition between crop types. By using standard John Deere values and retrieving data on your current threshing and separating conditions, it automatically adapts your machine to optimise its performance. You can then use these proposed values or modify and save them for later use.
The HarvestSmart system automatically adapts the speed of the combine to maximise capacity or minimise losses with the highest output. Sensors on the threshing cylinder, the engine, and the dedicated loss sensors control the system with the goal of minimising losses or maximising the throughput rate.
Full performance on hills
The secret to stable hillside performance is the Dyna-Flo™ Plus cleaning shoe. It all starts with the conveying augers, which move the material evenly onto the cleaning shoe. There’s no chance of the material sliding down or moving to one side.
Once the material reaches the cleaning shoe, the real innovation shows. The whole shoe is longer than before and is also longer than comparable concepts from competitive models. This means the crop stays on the chaffer and sieve longer.
The longer it stays, the more time it has to be separated and the less chance it has of going out the back of the combine, which reduces losses. This technology allows operators to cover slopes of up to 7 percent.
The side hill performance package for slopes up to 14 percent contains chaffer dividers, grain agitators, and grain pan diverters. These prevent grain from accumulating to one side and help distribute it over the full width of the chaffer. The agitators actively move grain uphill with every stroke, while the dividers and diverters prevent grain from moving downhill on side slopes. Together with the in-base technology at the cleaning shoe, you can be confident of harvesting in slopes of up to 14 percent without any compromises or grain losses. This simple and reliable solution has no moving parts either, so it’s maintenance and wear free.
John Deere does not like compromises and knows the physical limits of machines on steep slopes. That’s why John Deere offers the HillMaster self-levelling system for the T-Series, simply because it is the best solution for steep slopes. The HillMaster system not only adjusts the chaffer and the cleaning shoe, it levels the whole combine from the feederhouse to the chopper.
This means the whole crop flow behaves exactly as if the combine was harvesting on level ground. The grain tank also stays level, which gives you the added benefit of being able to carry a full load even on slopes, saving additional unloading stops. HillMaster won’t just be appreciated when it comes to measuring your yields either. It’s a lot more comfortable for the operator, too.
HillMaster also has the added benefit of keeping the weight distribution even. Without it, the wheels on the downhill side of the combine would experience more load, which would increase soil compaction. By levelling the whole body of the combine, HillMaster shifts the centre of gravity so there’s even ground pressure across all four wheels. This also ensures that the combine has better traction and stability on slopes. This is an important consideration in unstable or wet soils.
Choose between fine cut and the extra-fine cut choppers
Depending on the desired degree of chopping, you have a choice of two high performance solutions: the standard fine cut chopper and the premium extra-fine-cut chopper.
Both models evenly distribute the residue behind the combine, even across the widest bouts, creating ideal conditions for subsequent field work. You can choose between smooth knives for greater fuel savings or serrated knives for optimum straw chop length. The extra-fine-cut chopper’s optional wind paddles ensure even straw distribution across the entire width of even the widest platforms. The low position of the chopper allows it to perform in windy conditions, while its high blast speed eliminates the need for resource-intensive active spreading.
Whether in chopping or windrowing mode, the chaff is always distributed through the chaff spreader and never through the chopper.
30 percent larger footprint
Everyone knows tracks are better than tyres when it comes to unstable ground and muddy conditions, but tracks don’t win in every situation – until now.
20 percent more comfort and a smoother ride
John Deere has completely rethought the whole concept of tracks from the ground up. The updated design represents a leap in performance in every area:
Excellent performance
The updated design retains all the benefits of the previous tracks: retrofitability, hydraulic suspension, five-contact-point technology, positive drive with triangular profile, and a climb-out-of-mud effect.
Larger footprint and narrower width – the tracks are longer compared to the previous design and compared to the design of most competitors’ machines. This puts more tread on the ground for better grip, lower soil compaction, and improved fuel economy compared to wheeled machines. The footprint of the 61-cm (24-in.) tracks is comparable in many cases to 73.7-cm (29-in.) wide competitors' tracks, but with the added advantage of a narrower transport width.
Triangular design for good ground clearance
All-terrain capability and exceptional ride quality – the triangular design provides good ground clearance and has excellent self-climbing properties in unstable ground. The five-pivot-point design with small distances between the pivot points and rollers ensure the tracks tightly follow the ground for better grip. Another advantage is significantly reduced vibration for better ride quality.
Zero maintenance – apart from being incredibly tough, another advantage of the IPX 2000 material being used is its self-lubricating properties which reduce wear and tear. Sealed gearboxes and bearings also remove the need for regular greasing. All that’s needed is an oil change every 500 hours.
Longer wear life
Exceptional grip and long life – the track treads are designed with a higher profile for longer wear life. The deep pattern also provides greater grip. They’re self-cleaning thanks to the 55-degree angle between the bars which promotes mud release. Tests show the pattern reduces friction with less heat generated, which reduces wear by as much as 50 percent compared to previous John Deere tracks.
