Features

Steering

    The steering system uses load sensing of hydraulic pressure required to efficiently complete the designated tasks. The pressure- and flow- compensating pump produces excellent stationary or creeping ground speed steering response to handle demanding applications.

    ActiveCommand Steering (ACS™)

    #

    With ACS, John Deere has designed one of the most robust and full-encompassing steering system in the industry. Whether in the field or on the road, ACS reduces steering effort, which can result in reduced operator fatigue and can improve operator comfort.
     
    There are four key features of the ACS system:

    Dynamic road wheel offset

    • A gyroscope senses tractor yaw and can automatically make small steering adjustments to provide unprecedented line-holding abilities. Drive down a bumpy road and experience how ACS makes it easier to keep the tractor straight, even over rough terrain.  ACS delivers the ultimate in comfort.
    • ACS works to prevent oversteering when a sudden obstacle causes the operator to make a quick steering reaction.

    Variable ratio steering

    • Approximately 3.5 turns lock to lock at in-field speeds for quick headland turns.
    • Approximately 5 turns lock to lock at transport speeds.

    Elimination of steering slop and hand wheel drift

    • Steering wheel drift and slop are eliminated with the ACS electronic control system.

    Variable effort steering

    • Steering wheel resistance automatically changes with ground speed to deliver light steering effort at slower speeds for less effort during headland turns, and higher steering wheel torque at transport speeds for better operator comfort.
    A fail operational system

    The ACS system is fail operational, which means steering is still functional in the event of any single-point failure. John Deere has gone to great lengths to help ensure the operator can steer the tractor if something goes wrong in the steering system.
     
    For example, if the primary controller fails, a second controller takes over. If power from the alternator is lost, the battery resumes control. If the engine quits running and is unable to supply hydraulic oil to the system, an electric-driven backup pump is used to supply the oil.

    ACS componentsACS components
    #

    The ACS system consists of several key components:

    1. Gyroscope: this is used to measure the yaw rate (turn rate) of the tractor during transport speeds.
    2. Road-wheel angle sensors: these sensors simply measure the steer angle of the tractor.
    3. Power supply module: this module distributes the power of the battery and alternator throughout the ACS system.
    4. Hand-wheel angle sensors and tactile feedback unit: this includes the steering wheel position sensors and a brake, which can increase or decrease resistance dependent on speed. Lighter feedback is desired during normal field use, and slightly heavier feedback is desired during transport and while the tractor is cornering at high speeds.
    5. Controllers: two controllers are located in the back of the tractor and are the brains of the system.
    6. Control valves: also known as steering valves, control valves are used to steer the tractor.
    7. Electric-drive backup pump: this pump supplies oil to the steering system, brakes, and park brakes (for towing) if there is no longer a sufficient oil supply to the steering and brakes.

    • Eliminates hand-wheel backlash and drift
    • Reduces steering effort, resulting in reduced operator fatigue
    • Smaller hand-wheel diameter for improved operator comfort and visibility
    • Maintains operator feel and touch points of traditional steering column system
    • Fully integrates with AutoTrac™ guidance system
    • Compatible with suspended and non-suspended front axles
    • Compatible with wide- and narrow-section width tires
Hydraulically actuated, power wet-disc brakes

    The brakes are designed with large-diameter rear disc brakes and powerful activating pistons. The brakes run in oil for cooling and long life in the most demanding situations. Braking in the field during a turn can be accomplished with light pedal effort and excellent modulation of brake forces.

     

    Hydraulically actuated, power wet-disc brakes:

    • Never require adjustment
    • Oil cooled for long life
    • Tractors equipped with front brakes use annular pistons that automatically retract after each braking operation to reduce friction for better fuel economy
    • Self-equalizing feature ensures even braking to each wheel
    • Integrated backup braking capabilities built into the brake system to provide positive brake engagement should the engine or hydraulic system fail
    • Brake valve is located externally of the cab to provide a quiet operating environment

    An integrated park brake is included with all transmission options.

     

    Front wet-disc brakes are included on 8R Series Tractors equipped with the 50-km/h (31-mph Independent-Link Suspension (ILS™) axle and 7R Series Tractors equipped with a 50-km/h (31-mph) Triple-Link Suspension (TLS™) Plus front axle. Front Brakes are optional equipment on the 8R 42-km/h (26-mph) ILS axle and 40-km/h (25-mph) TLS Plus front axles.

     

    Foot brakes on tractors equipped with AutoPowr™/Infinitely Variable Transmission (IVT™) transmissions have an integrated AutoClutch™, as described in the IVT section. Similarly, foot brakes on tractors equipped with e23™ transmissions have integrated AutoClutch™, as described in the e23 section.

     

    For towing very large loads, the 7R and 8R Series Tractors can be equipped with a complete air-brake-system or a hydraulic brake coupler, or both. The brakes supply air or oil pressure to a brake-equipped trailer or implement.

Cooled exhaust gas recirculation (EGR)
    PowerTech™ PSX 9.0-L enginePowerTech™ PSX 9.0-L engine
    #

    How exhaust gas recirculation (EGR) works

    EGR reduces the high temperatures where nitrogen oxide (NOx) compounds are formed in the engine cylinders by replacing excess oxygen with a prescribed amount of cooled exhaust gas.

    Exhaust gases contain more carbon dioxide than oxygen. The EGR valve in conjunction with the venturi and engine control unit (ECU) allows a controlled amount of exhaust gas to enter the intake manifold to mix with the incoming fresh air. Replacing excess oxygen with cooled exhaust gas leads to lower combustion temperatures, creating less NOx. In addition, EGR allows for advanced timing, leading to optimal performance of the engine, maximizing fuel economy.

    The following diagrams illustrate how air flows through the engine.

    For added performance and efficiency, the engine passes the exhaust gases through an EGR cooler before it enters the engine.

    PSS engine diagramPSS engine diagram
    #

    Flow of exhaust during engine operation
     
    Exhaust airflow enters into the EGR cooler from the exhaust manifold near the turbocharger.

    Based on engine load, air temperatures, and rpm, the engine control unit (ECU) opens or closes the EGR valve, allowing a measured percentage of exhaust gas to enter the intake manifold.

    The gases mix with the rest of the incoming air from the turbocharger and aftercooler before entering the cylinders.

    The 7R, 8R, and 8RT Series Tractors feature two lighting package options:

    • Standard 
    • Premium

    The cab lighting pattern provides 330 degrees of coverage while the hood lighting provides the remaining 30 degrees for completely programmable 360-degree, stadium-style lighting. This ensures there are no dead zones or lighting adjustments needed. The lighting configurations are available to match various applications and ensure maximum around-the-clock productivity.

    Bulb housings are large, allowing for optimum total lumens and available light. The standard lighting packages use 65-W halogen bulbs, whereas the premium lighting package uses light-emitting diode (LED) lights. In the premium lighting package, these tractors take advantage of the high-performing and efficient LED technology.

    The low- and high-beam driving/work lights are adjustable. Please refer to the electrical section in the operator’s manual for complete details on adjusting lights.

    Premium lighting

    Eight front grill-mounted lights:

    • Two 65-W low-beam halogen driving/work lights (mid grill screen)
    • Two LED high-beam driving/work lights (top of grill screen, hood mounted)
    • Two front corner-facing LED work lights (top of grill screen, hood mounted)
    • Two front-facing LED working lights (top of grill screen, hood mounted, inner position on the sides)

    12 cab roof-mounted lights:

    • Four side-facing LED lights
    • Four corner-facing amber lights
    • Two rear-facing LED lights
    • Two adjustable front roof LED lights

     

    Other lights:

    • Two rear fender-mounted LED lights
    • Two rear turn signal and brake lights (fender mounted)
    • Two folding-extremity lights
    • Two front belt-line LED floodlights
    • Rotary beacon light

     

    The premium lighting package replaces all previous halogen and HID lights with LED lights. The only lights that are not LED are the low-beam driving lights, they remain halogen. This allows each LED light to work at a lower temperature and no one light works harder than any other. The uniformity in LED coverage allows only one type of light output surrounding the tractor.

     

    The lighting pattern in the premium package provides industry-leading performance in nighttime visibility. LED bulbs provide maximum brightness and a true color output for excellent field definition that is easy on the operator's eyes.

     

    The LED lights provide 40 percent greater coverage width and 10 percent more light coverage in the rear. LED lighting packages use 45 percent less amps than standard halogen lights and have an increased life expectancy over HID lights which leads to lower costs of ownership over the life of the tractor.

     

    NOTE: Lighting packages may vary depending on region.

    Programmable exit lighting

    Another feature is programmable exit lighting. Exit lighting allows the lights outside the cab to stay on for up to 300 seconds.  They can be programmed in increments from 0 to 300 seconds.

     

    Refer to the operator’s manual for complete instructions on programming field, driving, and exit lighting.

ISOBUS and tractor-baler automation offer new baling experience
    Tractor-Baler Automation simplifies baling experience
    A single manual action; system manages the restA single manual action; system manages the rest
    TBA awardsTBA awards

    The optional Tractor-Baler Automation (TBA) makes baling easy. This exclusive system manages most of the baling process and gives the customer the following advantages:

    • High baling comfort a single action to bale instead of four.
    • Error proof baling - even after 10 working hours, the system does not forget any action; a true advantage for an inexperienced driver.
    • Constant bale quality - same diameter bale after bale
    • Constant productivity - no reduced efficiency due to operators fatigue.

    When used with a John Deere ISOBUS tractor, electric selective control valve (E-SCV), and (IVT™) transmission, the system will be able to:

    • Stop the tractor when bale size is reached
    • Wrap the bale
    • Open the gate
    • Close the gate when bale is unloaded

    The only action remaining is to forward reverser and manage the steering.

    If the John Deere tractor is not equipped with IVT but has E-SCV and ISOBUS, opening and closing can be automated.

    A single touch on SCV, brakes, or reverser will disengage the automation. In the same way, automated open/close can be momentarily stopped when unloading in hilly conditions.

    Tractor-Implement Automation is an exclusive green on green advantage. This advanced technology option has won awards at SIMA and Agritechnica farm equipment show in Europe, a true cost/value guarantee.

    NOTE: to run through fully automated mode, a John Deere Isobus tractor with E-SCV and IVT is required. A baler activation key and a tractor activation key (different) have to be ordered.

    The e23 transmission delivers smooth shifting and intuitive controls with Efficiency Manager™ feature in a reliable 23-speed PowerShift™ transmission. The e23 transmission is available for all 7R, 8R, and 8RT Series Tractors.

     

    The e23 has evolved from more than 50 years of John Deere PowerShift technology. With more automatic features, the e23 is easy to operate for all levels of operator experience. For more advanced operators looking to customize the transmission to best fit their operation, the e23 offers a custom mode.

    As the next generation of PowerShift technology, e23 delivers the strength to handle sudden, high-torque power loads while maintaining responsive, quick, and smooth shifts.  The e23 with Efficiency Manager provides improved fluid efficiency and overall productivity with limited input from the operator.

     

    e23 options

    • e23 transmission 42 km/h (26 mph) with Efficiency Manager
    • e23 transmission 50 km/h (31 mph) with Efficiency Manager

    Even gear spacing for optimal performance


    The e23 has 23 forward gears and 11 reverse gears, which are all evenly spaced. Forward gears are spaced 15 percent apart, while reverse gears are spaced approximately 30 percent apart, providing operators smooth shifting between gears.  Even spacing improves efficiency and allows for smooth, automated shifts when using Efficiency Manager. The e23 can reach maximum forward ground speed in gear F20. As a result, gears F21-F23 maintain maximum ground speed at reduced engine rpms to save fuel.

     

    e23 controls

     

    The e23 is available with either a right-hand or left-hand reverser.

     

    Right-hand reverserRight-hand reverser

    Right-hand reverser

     

    A convenient, right-hand reverser is available with the e23 transmission. The reverser is located on the CommandARM™ as shown above.

    • Forward direction selector
    • Reverse direction selector
    • Neutral position
    • Electronic park lock

     

    Right-hand reverser equipped models use three main controls to operate the tractor:

    • Foot brake with integrated AutoClutch
    • Set speed adjuster
    • Gear selector control lever with integrated reverser

     

    The right-hand reverser control strategy combines speed control and direction control into one multi-function lever that is conveniently located on the CommandARM. This is a good choice for most common field applications since tractor speed and direction are not constantly being adjusted by the operator.

     

     

    Left-hand reverser
    Left-hand reverserLeft-hand reverser
    Left-hand transmission leverLeft-hand transmission lever

    An easy-to-use left-hand reverser is available with the e23 transmission and includes the same functions as the right-hand reverser. The reverser control is located at the 10 o’clock position on the steering column for intuitive control.

    The five-position, left-hand reverser column incorporates the following controls:

    • Forward direction selector
    • Reverse direction selector
    • Neutral position
    • Electronic park lock

    Left-hand reverser equipped models use four main controls to operate the tractor:

    • Foot brake with integrated AutoClutch™ function
    • Set speed adjuster
    • Gear selector control
    • Multi-function left-hand reverser

    The left-hand reverser control strategy separates the direction control lever from the speed/gear control lever on the CommandARM. This strategy is a good choice for operations requiring the right hand to run multiple operations on the CommandARM or applications requiring constant directional changes like loader work.

    Determining which reverser is best suited for a specific operator depends on a few key factors. Consider the following to help choose between a left- or right-hand reverser.

    • Operator preference and ergonomic benefits.
    • Operators in loader applications might prefer a left-hand reverser since direction changes occur frequently while their hands are on the steering wheel (near the left-hand reverser location).

    Producers primarily in row-crop applications using features like AutoTrac™ assisted steering system or operating with the seat swiveled to the right for easy access to monitors and displays might find the right-hand reverser more convenient. Speed and directional controls are in one location on the CommandARM.

     

    Foot brake with integrated AutoClutch function

    The electrohydraulically controlled brakes on e23-equipped tractors have an integrated AutoClutch function.

    • At low idle only, the tractor will stop by depressing only one brake pedal.
    • Pressing both brakes (locked together) simultaneously will stop the tractor from any ground or engine speed.

    Braking can be done on flat ground or steep slopes simply by using the brake pedals; it is not necessary to depress the clutch.

    • It is recommended to lock the brake pedals together when operating on roads.

     

     
     Foot brake with integrated AutoClutch


    AutoClutch sensitivity can be adjusted through the Generation 4 CommandCenter™ display. AutoClutch can be deactivated on e23 transmissions as well; however, it will be reactivated after every key start.

     

    #
    Full auto mode
    Full auto main pageFull auto main page
    #

    Full AUTO mode enables the tractor to make adjustments to the transmission operating mode automatically, based on engine and transmission speed and the load on the tractor. This means the tractor will shift up and throttle back automatically to reach the desired ground speed efficiently.  Operators have the ability to set the maximum forward and reverse speeds for the tractor in their particular application.

     

    When shifting in full AUTO mode, the transmission shifts set speeds, meaning the transmission may not necessarily shift gears each time the lever is bumped. Efficiency Manager is automatically engaged while operating in full AUTO mode. As a result, shifting will not take the tractor out of Efficiency Manager in full AUTO mode.

    Stopping the tractor using AutoClutch

    During transport, it may be desirable to use the AutoClutch feature to stop the tractor when approaching an intersection or turn. Braking the tractor using the AutoClutch at high ground speed and engine speed will require high brake-pedal force.

     

    Rather than using AutoClutch alone, reduce the engine rpm and reduce the e23 to a slower commanded speed before applying the AutoClutch. This will help to reduce the force needed to stop the tractor with the AutoClutch. The tractor will accelerate to the previously commanded speed upon release of the AutoClutch, repositioning of the hand throttle and increasing the commanded speed.

     

    NOTE: The preferred method of stopping heavy towed loads is to reduce the e23 commanded speed and lower engine rpm first, and then depress both brake pedals. (Brake pedals should be locked together.)

    Using individual brake pedals - implement hook-up

    Individual brake pedals can be used to assist slow-speed off-road turning, such as hooking up to an implement. At low idle, the AutoClutch feature will stop the tractor if the operator depresses only one brake pedal.

    To assist in hooking up an implement, depress either brake pedal while slowly increasing engine speed until the desired turn is achieved. Returning engine speed to a low idle while continuing to depress one brake pedal will slow the tractor to a stop.

    The CommandCenter is the central information system for tractors and allows the operator to program various settings tailored to a specific operation.

    To access the tractor’s transmission settings, press the transmission shortcut button on the CommandCenter shortcut bar.

    Operating modes


    The e23 application settings employ three modes to take full advantage of the engine-transmission communication: full auto mode, custom mode, and manual mode.

    Custom mode
    e23 custom transmission pagee23 custom transmission page
    #

    Custom mode allows operators to adjust operating parameters to meet their specific operation. Just like full AUTO mode, custom mode shifts set speeds meaning the transmission may not necessarily shift gears each time the lever is bumped.  Efficiency manager is engaged automatically in custom mode.

     

    Eco buttonEco button
    Display screenDisplay screen

    In custom mode, eco allows two minimum engine speeds to be set. Operators can turn eco on and off by either pushing the eco button on the side of the throttle or by selecting eco in the transmission settings page of the CommandCenter.  For example, operators may choose to turn eco on during transport to utilize a lower minimum engine speed and then turn eco off while operating in the field where a higher minimum engine speed is desired.

     

    Custom settings pageCustom settings page
    #

    In the advanced settings page, operators can customize the auto shift engine speed droop as a percentage of the full engine speed.  In addition, the load anticipation feature can be enabled for the hitch engagement, hydraulic engagement, or both.

    Manual mode
    Manual mode pageManual mode page
    #

    Manual mode operates similar to a traditional PowerShift transmission. When shifting, the transmission shifts gears, not set speeds like full AUTO and custom mode.  Manual mode also features efficiency manager when the operator engages set speed one or two on the CommandARM, as shown above in illustration.

     

    When operating in manual mode with efficiency manager active, there is the option of turning eco on or eco off.  This allows the operator to select two different minimum engine speeds.  In the advanced settings page, operators can adjust auto shift engine speed droop and load anticipation, similar to custom mode.

    Advanced transmission settings

    Additional transmission settings can be customized to the operators’ specific desires.

    AutoClutch sensitivity can be adjusted on the transmission settings page in the CommandCenter display. Operators can turn off AutoClutch or choose from high, medium, or low sensitivity. Operators can fine-tune AutoClutch by delaying the response time, based on load, travel speed, etcetera. This allows the trailer brakes to be applied before AutoClutch engages.

    • High: for light or no trailer (load) – factory default
    • Medium: for medium trailers (load)
    • Low: for heavy trailers (load)
    • AutoClutch Off: to operate e23 just like a traditional powershift

    The AutoClutch sensitivity factory default-setting is set to high, which supports most operations.

     

    AutoClutch sensitivity settings are available in all three modes – auto, custom, and manual.

     

    Efficiency manager

     

     

     

     
     Set speed buttons and set speed adjuster


    Efficiency manager is automatically enabled in full AUTO and custom mode. Efficiency manager can be turned on in manual mode by selecting the set speed one or two on the CommandARM. The set speed adjuster on the top of the single-lever gear selector allows the operator to dial in the desired ground speed to establish set speed one or two in Efficiency Manager.
     
    Efficiency manager allows the transmission to up or down shift and change engine rpm to maintain the set wheel speed. To reach the desired set speed, the throttle must be set to full engine rpm. This allows efficiency manager to shift the transmission and adjust engine speed to maintain the desired wheel speed. For more information on Efficiency Manager refer to the operator’s manual.

     

    e23 operation


    Both right-hand reverser and left-hand reverser control options provide full powershifts for on-the-go shifting; no need to stop or clutch when bump shifting or shuttle shifting between forward and reverse.

     

    The single-lever shifter allows for quick and convenient shifting with minimal physical effort.
     
    Shifts are made either by bumping the lever or by holding the lever in a forward or rearward position.

    • Transmission is in neutral when the shift control or left-hand reverser is not in park, forward, or reverse.
    • Operator presence feature prevents the transmission from going into gear when the operator is not seated or has the brake or clutch pedal depressed.
    • Transmission can be programmed to start in 1F – 13F or 1R – 6R.

    A forward gear between 1F and 13F may be preselected by depressing the clutch pedal and pushing or pulling the shift lever. The transmission will then start in the preselected forward gear when clutch pedal is released.

    Rapid shifting
    Rapid shiftingRapid shifting
    #

    When the tractor is working in a light-load condition, for example in transport, the transmission can be shifted rapidly by bumping the shift lever.

    To reach transport speeds quickly:

    • Depress clutch pedal and rapidly bump shift lever to 13F
    • Transmission will shift directly to 13F when clutch pedal is released
    • Transmission will skip some gears as it keeps up with the operator’s command, allowing the tractor to accelerate to transport speed quickly
    • Once tractor is underway in 13F, bump the shift lever to reach desired ground speed 

    Double shifting

    The transmission can skip a gear when operating under load by double bumping the shift lever.

    • This aids the ease of deceleration/acceleration when approaching and departing headland turns. 

    Ground speed matching

    When the tractor is slowing down and the clutch pedal is depressed, the transmission will match a gear to the ground speed of the tractor when the clutch is released. Ground speed matching only engages in gears 13F higher.


    Setting start-up gears

    The transmission defaults to 8F and 3R at start-up. However, these default start-up gears can be adjusted from 1-13F and 1-6R through the CommandCenter. Refer to the operator’s manual for additional information.

     

     

     
    Start-up gears in advanced settings

     

    Releasing the park brake

    The e23 transmission utilizes a spring-engaged/hydraulically-disengaged park brake. The park brake control feature prevents accidental park brake engagement when tractor is moving at high speed.

     

    On tractors equipped with air brakes, the park brake automatically activates the air brake system.

    Premium hitches include a push bar and heavier lift arms:

    • Hitches with zero front auxiliary valves include one mid-mount valve.
    • Hitches with one front auxiliary valve include two mid-mount valves.
    • Hitches with two front auxiliary valves include three mid-mount valves.

    To ensure adequate hydraulic availability, up to two selective control valves (SCVs) can be included with a front hitch.

    Joystick controlJoystick control
    Paddle pot SCV controlsPaddle pot SCV controls

    Tractors equipped with a factory front hitch have the option of selecting a joystick control or paddle pot SCV controls. The joystick control is not compatible with the sixth rear electrohydraulic SCV because of the CommandARM™ space required for the front hitch joystick.

    The integrated and styled compact hitch design maintains full maneuverability even with the larger front tires. The hitch extends only 55-mm (2.2-in.) ahead of the front support when the arms are folded.

     

    Standard (carrier version) hitches can be converted to a premium (ground-engaging) hitch by ordering and field installing a conversion kit that includes push bar and heavier lift arms.

    All factory-installed front hitches are capable of single- and dual-acting hydraulic cylinder modes. This allows the operator the flexibility to choose the correct mode for a variety of front hitch applications. Single acting provides hydraulic force for retracting the front hitch cylinders and allows front implements to follow the contour of the ground or surface. For example, this would be the correct mode for a front-mounted snow blower. Dual acting provides hydraulic force in retracting and extending the front hitch cylinders to provide down force for ground-engaging implements.

     

    Additional hitch features include:

    • Integrated and protected routing of oil lines
    • Category 3 top link with storage position
    • Integrated towing clevis with pin
    • Compatible with group 42 - 44 front tires
    7R position sensing7R position sensing
    #

    The 7R with front hitch comes equipped with position sensing that allows operators the ability to establish an upper height limit set point and lower limit set point through CommandCenter™.  Position sensing maintains the height of the hitch arms based on the set points.
     
    Position sensing provides the following benefits:

    • Add to iTEC sequence (raise/lower set points)
    • Limit height for front-PTO implement (stay within desirable driveline angles)
    • Set lower position for ground-engaging depth or blade position
    • Maintain set height without added fixed link (position will auto correct)
    • Prevent inadvertent hitch operation outside of desired range of motion (takes guesswork out of placing height of front implement)
    • Less fatiguing for repetitive-type work where the same position is required over and over

    For a 9-pin connector, order kit RE322555. The kit includes all necessary components and allows ISO implement communication.

     

    NOTE: 7R Series Tractors with a factory-installed front hitch do not ship with a front weight support.
