G5^Plus CommandCenter™ Display

• Improved visibility with 55 degrees of swivel to the right

Heated and cooled floor ventilation

• Floor vents placed directly behind operator’s feet improves airflow heating during cold mornings or cooling throughout warm days

CommandARM™ console

• Easily accessible storage compartments located to the right and behind the seat

The G5^Plus CommandCenter is the central information system used on all John Deere S7 and X9 Combines. The display allows the operator to view various important harvest and diagnostic information during harvesting and organized in a layout based on operator preferences. The G5^Plus CommandCenter has been developed in combination with the CommandARM™ console and the multifunction control lever to deliver outstanding ergonomics paired with best-in-class natural navigation.

Benefits

• Display is easy to use due to its commonality across John Deere agriculture products
• Large area for information provided by a 32.5-cm (12.8-in.) screen
• Quick and easy navigation with touch functionality similar to Gen4 displays
• 10 percent less button presses compared to the previous design because of app-based interface
• Easy, logical, and intuitive operation with five run pages which can be customized by the operator
• Improved uptime due to display interface time savings, including shortcut keys below the display that allow access to the most important combine functions
• To increase the digital display area, an G5^Plus Extended Monitor is available

Ground Speed Automation dynamically adjusts combine ground speed during harvest based on various operator inputs and internal sensors around the machine. These sources are continuously evaluated and executed upon to command a harvesting speed:

• Terrain – Adjusts ground speed according to combine pitch
• Previous coverage – Increases ground speed for areas already harvested
• Grain Loss level – Quicker reaction of ground speed to changes in grain loss
• Engine power limit – Adjusts ground speed to maintain user defined engine power target
• Header height changes – Adjusts ground speed dependent on header height. Raising will incrementally increase ground speed, lowering will decrease
• Ground speed limit – Maximum harvesting ground speed threshold predefined by operator

Transition the traditional mindset from harvesting at a fixed speed, thereby feeding varying crop throughput, to instead a more productive viewpoint of maintaining consistent throughput by varying the machine’s ground speed proportionally with using automation. This, along with focusing less on controlling speed and more on other harvesting tasks, is the value achieved with Ground Speed Automation.

NOTE: A ProDrive™ or ProDrive XL Transmission is required to use Ground Speed Automation. Upon selecting this transmission, Ground Speed Automation is included from factory with any Connectivity and Technology Package.  

What’s New and Improved?

• Three unloading on-the-go speed modes to select from: Variable, Offset, or Fixed
• Ready to go! Eliminated the time-consuming system prerequisite to set an initial performance target to baseline. Allows quicker utilization of automation for customers and on-going learning through various field conditions.
• More inputs added for evaluating ground speed commands including terrain, header height changes, and previous coverage
• Enhanced responsive to grain loss detections
• With Ground Speed Automation on, utilize more engine rated power while maintaining threshing and separating results as components operate at designed speeds. NOTE: Operator cannot set engine power target above 100 percent
• Ground speed adjustments are signified to the operator in blue text when automation is making changes
• Updated status and diagnostic features for better understanding system performance and troubleshooting

Overview

The overshot beater makes the T6 unique in the industry. Over-the-top feeding to gently transfer material from threshing into the separation area. This enables larger wrapping angles at the concave and separating drum and ensures higher throughput with minimum losses even under the toughest separation conditions.

Benefits

• Large separation area due to size of the separator grate and rear beater
• Optimal and smooth crop flow to ensure unmatched straw quality
• Versatile concept to ensure uptime of the machine and easy crop conversion

Additional details

For those who desire the highest productivity and highest straw yields, the T-Series Combine is the right solution.

Dyna-Flo™ Plus cleaning shoe

The Dyna-Flo Plus cleaning system is developed and specially designed for the T6 Combines.

Features of the Dyna-Flo Plus cleaning system include:

• Auger-type preparation system with six augers
• Precleaning system – dual-stage step-pan design associated with air flow distribution separates chaff from free grain. Grain separated at the prep pan is conveyed to the chaffer via step floor.
• Chaffer and sieve system – aerated louver design with optional flat tooth comb (FTC) louvers for chaffer element
  • SlopeMaster system is standard on the chaffer to handle slopes up to 7 percent and enable easy access to the lower sieve.
  • Divided chaffer and sieve elements on wider T6 channel width enable convenient removal of shoe elements.
  • Extended length of sieve elements ensures increase of cleaning shoe area.
  • Front chaffer with two ventilated steps provides best prechaffer separation.
• Tailings are returned to the threshing cylinder.
• Cleaning shoe frame design – hybrid material cleaning shoe construction of aluminium extrusions, high-strength steel, nodular castings, and structural rivets is more immune to cyclical stresses.
• Fan is a barrel-wheel design with air inlets. An optional dual-range fan drive concept is available for special crops such as grass seed.
  • A unique wind board behind the fan scopes the air distribution need across the entire shoe width and length.

Two grain tank sizes are available 11,000 L (312 bu) and 13,500 L (383 bu) (requires ProDrive, not available with HillMaster). Together with the 150 L/s (4.3 bu/sec) unload rate they provide a perfect match for the productivity of this combine. 11,000-L (312-bu) grain tanks offer a high capacity to increase harvest time between unloading. With 13,500-L (383-bu) grain tanks providing the highest productivity for operators.

With 150 L/s (4.3 bu/sec) unload rate the tanks are empty again in 73 seconds (11,000 L [312 bu]) / 90 seconds (13,500 L [383 bu]).

Both grain tanks come with two grain-tank-level sensors to alert the operator when levels reach three-fourths and full. The grain tank levels are also tied into the beacon lights to alert grain cart drivers. A convenient hinged door panel provides quick access to obtain a grain sample. The grain trough delivers grain right to the sampling area for increased safety when taking an early grain tank sample.

For easier clean out all grain tanks are equipped with tool-less cross auger cleanout hatches.

Harvest has started, and grain is rolling into the bins. The combines are set, and the sample looks good, but the producers must be sure they considered their residue management needs. The straw must be chopped fine enough to minimize row-unit plugging and future tillage passes, and it must be spread evenly to enable uniform emergence and faster soil warming for next year’s crop. Next year’s harvest starts this harvest, and it begins with proper residue management.

On T6 Combines, John Deere offers both a fine-cut (FC) and extra-fine-cut (XFC) chopper to meet a wide range of cut quality needs. The following table shows the key configuration differences in the chopper types.

Depending on the producer’s needs, an XFC chopper could provide the additional cut quality they are looking for. Cut quality results vary depending on conditions. Test results have shown that the FC chopper with the knifebank at 100 percent engagement provides similar cut quality to the XFC chopper with the knifebank at 0 percent engagement as shown in the figure below. As knifebank engagement percentage on the XFC is increased, cut quality continues to increase as well as power consumed. Dealers and producers should be aware that the XFC chopper does consume additional horsepower and fuel compared to a FC chopper. The decision to utilize an XFC chopper versus a FC chopper needs to be carefully considered and needs to align with the producer’s overall residue management strategy.

Benefits

• Two chopper configurations are available to meet the customers residue management cut quality needs
• Potential for improved crop emergence and faster soil warm up
