S790 COMBINE

ActiveYield delivers automatic yield calibrations to the operator without spending time manually performing yield calibrations.

Feature benefit:

• Simplified yield calibrations for improved uptime in the field
• Simplified data collection for use during and after harvest

Functionality:

ActiveYield eliminates time-consuming manual yield calibrations and replaces them with automated sensors that calibrate the machine by measuring the grain as the tank fills. This enables decisions to be made in real time without leaving the cab.

ActiveYield sensors in grain tank

When the ActiveYield option is enabled and the Terrain Compensation Module (TCM) in the StarFire™ 3000 or StarFire 6000 Receiver has been calibrated, ActiveYield is ready to go to work. As grain is harvested and enters the tank, the three sensors within the grain tank collectively measure the grain as it piles over the cross auger covers. If all conditions are acceptable (header and separator on, grain is flowing, and machine level is within 4 degrees) load collection occurs from 900 through 3000 kg (2000 through 6600 lb).

Any pitch and roll of more than 4 degrees from center during load collection will cause the system to reject that load due to the grain pile shifting in the tank. A new calibration load starts once grain is below the sensors on the cross auger covers.

Stored calibration loads are replaced by new ones as the system continues to collect data. The system may be disabled at any time by accessing the moisture setup page and unchecking the ActiveYield box if manual yield calibration is desired.

ActiveYield Information

ActiveYield is available for model year 2016 through model year 2019 S760, S770, S780, and S790 Combines and requires the 4600 CommandCenter™ Display, GreenStar™ 3 2630 Display, or GreenStar 3 CommandCenter. Additionally, a StarFire 3000 or 6000 Receiver must be installed on the combine with the TCM calibrated for ActiveYield to detect machine pitch correctly. Manual yield calibration is not required as each crop has a built-in default value.

Harvest Doc™ system yield data collected by an ActiveYield system is only compatible with the John Deere Operations Center. John Deere does not guarantee compatibility of ActiveYield collected documentation with John Deere APEX™ software or third-party software systems.

The Combine Advisor application provides the tools needed to set the combine to get the most out of it and automatically adjust settings to maintain optimum performance. Inside this application on the 4600 CommandCenter™ Display, the operator will find many tools including easy-to-adjust current machine settings, sensitivity settings for automation, application status indicators, automation activity history overviews, and live feeds of grain analysis cameras.

Additionally, the operator can access Optimize Performance, activate the three automation technologies, and set the performance targets the machine will automatically adjust to maintain.

Feature benefits:

• Efficient combine operation with a one-page application for animation technologies
• Improved combine settings management with settings, sensitivities, and status information all on one reference page
• Reduced operator training and efficient, easy control of harvest settings through an intuitive run page and user interface

Functionality:

Auto Maintain

Auto Maintain with ActiveVision cameras is technology that works to automatically adjust five primary S700 Combine settings to maintain the user set performance target. When harvesting corn, soybeans, wheat, canola, or barley, the combine will maintain the performance of everything from grain loss and grain quality, to foreign material in the grain tank. The ActiveVision cameras, along with grain loss monitors, are specifically designed to identify the impact of crop condition changes and adjust the combine to maintain the performance target, allowing the operator to focus on other challenges of harvest.

Feature benefits:

• Simplify harvest by automating the critical workload of constantly managing combine settings when conditions change

• Increase productivity by allowing ActiveVision cameras to identify and address tough-to-spot problems such as cracked grain

• Provide flexibility in planning overall business and increase the efficiency of the combine independent of operator experience

Combine Advisor run page

Functionality

Auto Maintain looks at the level at which the combine is performing, sets that as the goal, and automates combine settings to continually hit the target performance goal over time. Auto Maintain uses existing sensor inputs along with the ActiveVision cameras to make decisions for accurate combine adjustments. It does not use grain moisture as an input, however. Auto Maintain is able to hit the target goal by automatically making adjustments to the threshing speed, concave clearance, chaffer clearance, sieve clearance, and fan speed. The ActiveVision cameras have been trained to analyze the clean grain and tailings material and input that analysis into the Auto Maintain system. Auto Maintain will show the operator how it has been performing with a constantly updating historical graph of losses, grain quality, and foreign material in the clean grain. The green-shaded area below indicates the performance targets set. The colored lines show the ongoing levels of losses and quality. For example, the green, purple, and orange lines below show a period of time outside of the green-shaded acceptable area. Auto Maintain recognizes this and makes the appropriate adjustments to meet the set targets.

Harvest is hectic. Producers are focusing on getting all the crop from the field to the bin within a tight harvest window. Using Machine Sync, those producers can focus more on grain harvest and grain quality, and worry less about keeping the grain cart under the spout when unloading on the go. Gen 4 Machine Sync provides a solution to harvest stress by creating a wireless network between the tractor and combine to enable on-the-go unloading by synchronizing tractor speed and direction of travel with the combine.

Machine Sync works with In-Field Data Sharing to show the location of all combines and tractors within the fleet of Gen 4 machines harvesting in the field. Knowing the exact location of multiple combines as well as their grain tank fill level and unloading auger status allows the grain cart operators to be in the right place at the right time. 

NOTE: Active Concave Isolation is only available on S780 and S790 Combines.

ACI increases throughput in tough threshing small grains and rice without sacrificing overall grain savings. This system allows producers to continue to harvest outside the optimal harvest window and conditions. The concaves are suspended by hydraulic cylinders that increase the amount of crop that is being threshed as well as reduces the amount of rotor noise that is heard by the operator.

Feature benefits:

• In tough threshing, small grains producers can see up to a 10 percent increase in machine capacity while maintaining their loss level when the combine is equipped with a tough crop packages
• In tough material handling conditions, the tough crop packages improve the throughput of the combine up to 20 percent to better utilize true machine performance outside the optimal harvest window and conditions, while accepting increased loss levels
• Improved drivability and ability to handle slugs
• Enhanced durability and uptime with the elimination of sheer bolts in the system
• Increased operator comfort with the reduction of concave banging noise

ACI

Functionality:

The ACI feature hydraulically suspends the concaves; the consistency of the concave gap is increased along with decreasing sensor drift for a more accurate concave distance. Material flow through the threshing section of the machine is smoother, giving more consistent threshing.

The Dyna-Flo Plus cleaning shoe is the heart of the S700 Combine cleaning system. The system is made up of a unique design consisting of aluminum and high-strength steel that reduces overall weight while maintaining overall strength. The Dyna-Flo Plus cleaning shoe also features an enhanced drive system that requires only one flywheel for optimal shoe performance and maximizes uptime.

Feature benefit:

• Increased size of the sieve area by 12 percent for up to an additional 0.6 ha (1.5 acres) per hour of productivity.
• Tailings volume reduction of up to 28 percent in coarse grains and up to 14 percent in small grains.
• Weight reduction of 180 kg (396 lb) for smoother operation and reduced combine ground compaction.

Dyna-Flo Plus cleaning shoe

Enhanced drive system

Functionality:

The Dyna-Flo Plus cleaning system begins with conveyor augers located beneath the concave area, where the volume of threshed material is highest, to evenly move material onto the cleaning shoe (1). The deep auger troughs provide uniform distribution of material to the cleaning shoe with less bunching, even on sloping terrain and when harvesting up and down hills.

Dyna-Flo Plus cleaning shoe

Once grain is on the cleaning shoe, the raised-center front chaffer cleans up to 40 percent of free grain before it reaches the main chaffer (3). High-velocity air from the cleaning fan elevates any light material traveling over the end of the front chaffer, resulting in more aggressive separation of chaff and increased cleaning performance (2). The main chaffer provides grain separation from chaff as the grain passes through the main chaffer to the sieve (4).

The sieve provides proper sizing of grain from material other than grain (5). Any grain that passes through the sieve is elevated to the grain tank while some grain or material other than grain flows to the tailings return system for reprocessing. On S760, and S770 Combines, the tailings material is directed back into the threshing section of the separator for additional threshing. The tailings material on the S780 and S790 Combines are directed to the active tailings return system for additional threshing, and then directed back on the return pan and then onto the main chaffer for additional cleaning (6).

Harvesting in slopes

Harvesting in rolling ground

The industry-exclusive ProDrive system uses PowerShift™ transmission technology to automatically shift between two speed ranges as ground conditions and terrain change to keep the combine harvesting at the desired ground speed.  Valuable harvest time will no longer be lost shifting on hills and when exiting fields to start transporting.

Feature benefit:

• Precise control of the combine speed (when going up or down hills) without the need to continuously monitor and adjust the multifunction control lever
• Retain high levels of productivity through the speed ranges with shift-on-the-go technology
• Maintain ground speed when engaging four-wheel drive (4WD) (if equipped)
• Operator-selected maximum speed within each range, allowing for more precise control of the combine in delicate operations (for example, when hooking up headers)

The ProDrive system on S700 Combines includes an integrated HarvestSmart™ feedrate control system to provide the maximum productivity and reduce operator stress and fatigue.

Functionality:

The ProDrive hydrostatic motor has a higher displacement than the previous hydrostatic systems. Both the pump and motor are variable-displacement components that allow ProDrive to maintain high levels of torque to the ground throughout each of the two operating-speed ranges.

Range one can be set for typical harvesting speeds. Range two can be used when higher speeds are needed during harvest or when transporting the combine.

The ground speed can be infinitely varied within both modes by the operator, using the multifunction control lever on the CommandARM™ armrest console. The multifunction lever regulates the high-capacity, variable hydrostatic pump and motor that drives the ground speed.

Using the navigation tools on the armrest, the operator can dial in the desired maximum-attainable speed within each of the two speed ranges. The maximum forward speed in either range can be set from 0 to 38.6 km/h (0 to 24 mph). The maximum speed in range one cannot be set higher than the maximum speed for range two. For example, if a maximum harvest speed of 13 km/h (8 mph) is desired and set, the full forward position of the hydrostatic control handle will deliver the speed of 13 km/h (8 mph).

The ProDrive transmission is equipped with an electrohydraulic differential lock with a four-pinion differential.  Non-ProDrive combines have a two-pinion differential. When operating in muddy, hilly terrain or in sandy conditions that may cause one of the tires to lose traction, this differential lock enables the operator to maintain productivity. If traction is lost, the operator can quickly and easily engage the differential lock by pressing the differential lock button on the CommandARM armrest console. An indicator light within the button alerts the operator that the differential locking feature is engaged.

The TriStream rotor is unique to John Deere because it features a slightly tapered design in the threshing area for best-in-class grain quality while dramatically reducing the growling that often comes with heavy rotor loads. The TriStream rotor is recommended for producers who harvest mainly coarse grains along with easy-threshing small grains.

The spiral vanes surrounding the rotor guide the crop material through the threshing and separating area in a pull-and-release action to improve performance. This John Deere S700 Combine feature will generate less power consumption.

Feature benefits:

• TriStream rotor technology reduces the force required to move material through the combine by as much as 20 percent, maximizing fuel efficiency.
• The rifling grooves on the threshing elements allow the bullet-shaped rotor to move material more efficiently, maximizing crop threshing performance and grain quality.
• Heavy-duty vanes on the top covers propel the crop smoothly rearward through the length of the rotor, ensuring all the threshed grain is separated.

S700 TriStream rotor

Functionality:

Fifteen cast-constructed threshing elements provide superior material handling with excellent grain quality.  The elements spiral around the rotor to control material flow.  In some harvesting environments, the dense-pack configuration (nine additional threshing elements) may be necessary. 

TriStream threshing elements

Conical top covers allow for smooth material movement within the threshing and separating area. The top covers have a radius larger than the rotor, allowing the material to expand as it travels along the top of the rotor. This design uses the pull-and-release action of crop material, aiding in the threshing and separating to reduce power consumption.

Conical top covers

The industry-exclusive variable-stream rotor features a tapered design in the threshing section, which improves crop flow, enhances grain quality, and reduces power consumption. The variable-stream rotor with adjustable top cover transport vanes is recommended for producers of rice and in tough threshing conditions.

The variable-stream rotor smooths crop flow during tough handling conditions to maximize throughput. Along with the tough-material handling capabilities of the variable-stream rotor configuration, the straw quality and length can be improved due to the electrically adjustable top cover transport vanes.

Feature benefits:

• The longer rotor taper in the threshing area allows improved material handling by providing smoother crop flow through the combine, maximizing threshing performance and fuel efficiency.
• Electrically adjustable transport vanes allow operators to change the vane angle from the cab for improved straw quality.

S700 variable-stream rotor

Functionality:

Fifteen cast-constructed threshing elements provide superior handling, improved durability and serviceability, and maintain excellent grain quality. The elements spiral around the rotor to move and control the material. In some harvesting conditions, 12 additional bolt-on threshing tines may be installed for increased material handling.

Rear discharge flights and a tapered rear cone improve material handoff to the rear discharge beater.

Electrically adjustable transport vanes allow operators to change the vane angle within the cab. Longer straw length can be accomplished when vanes are in the advanced position.
