With the current software generation all paddle pods, and the electrical joystick are reconfigurable giving operators free choice to customize all controls depending on applications, drivers, implements or other requirements.
The following information has to be considered for all reconfigurable controls (electrical joystick and selective control valve [SCV] paddle pods):
To set up the electrical controls in the CommandCenter the operator has the possibility to select from different functions. The following functions can be reconfigured to the different controls:
Additionally, in the CommandCenter notification about the default settings there is an additional label on the right-hand side window to show the factory default settings for Settings Manager.
For using ISOBUS push functions on the electrical joystick, the operator can select the buttons of the electrical joystick in the CommanCenter. There are two ways of setting up the ISOBUS functionalities:
NOTE: Please also see available attachments.
NOTE: If the multifunction lever is operated in tractor mode, variable functions can be assigned to the lever directions fore/aft and left/right and to the rocker switch on the multifunction lever. This assignment can be viewed only on the Controls Setup page (for more information see below).
A Pull multifunction lever rearward until the functions of the implement are performed at the desired speed. Do not move the lever beyond the kiss pressure.
C Move multifunction lever to the left until the functions of the implement are performed at the desired speed. Do not move the lever beyond the kiss pressure.
The bucket shake function is activated in the same way as in loader mode.
F Push the multifunction lever forward until it is beyond the point of perceptible kiss pressure (click point) and then release it.
G Push the multifunction lever all the way forward and engage in detent to activate the float position. The lever remains in the detent until it is pulled back by hand.
J Move the multifunction lever all the way to the right and engage it to activate the float position. The lever remains in the detent until it is pulled back by hand.
The operator can choose from different functions for the CommandARM controls:
The operator also has the possibility to set all reconfigured controls (custom) for the paddle pods and the electrical joystick back to the factory settings (default) in the settings.
This can be done in the advanced settings.
The e23 transmission delivers smooth shifting and intuitive controls with Efficiency Manager™ in a reliable 23-speed PowerShift™ transmission. The e23 transmission is available for all 7R, 8R and 8RT 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.
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 apart with a 15 percent speed differential between each gear, while reverse gears are spaced apart with a approximately 30 percent speed differential, 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 on 40-km/h (25-mph) transmission.
The e23 is available with either a right-hand or left-hand reverser.
A convenient, right-hand reverser is available with the e23 transmission. The reverser is located on the CommandARM™ controls as shown above.
Right-hand reverser equipped models use four main controls to operate the tractor:
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.
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 four-position, left-hand reverser column incorporates the following controls:
Left-hand reverser equipped models use five main controls to operate the tractor:
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.
Producers primarily in row-crop applications using features like AutoTrac™ 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.
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.
The e23 application settings employ three modes to take full advantage of the engine-transmission communication: full auto mode, custom mode, and manual mode.
The electrohydraulically controlled brakes on e23-equipped tractors have an integrated AutoClutch function.
Braking can be done on flat ground or steep slopes simply by using the brake pedals; it is not necessary to depress the clutch.
AutoClutch sensitivity can be adjusted through the Generation 4 CommandCenter™. AutoClutch can be deactivated on e23 transmissions as well; however, it will be reactivated after every key start.
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.
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 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 AUTO mode. As a result, shifting will not take the tractor out of Efficiency Manager in AUTO mode.
Custom mode allows operators to adjust operating parameters to meet their specific operation. Just like 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.
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.
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 operates similar to a traditional PowerShift transmission. When shifting, the transmission shifts gears, not set speeds like 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.
Operators can lock-in a desired ground speed by pushing the button on the side of the hand throttle when the foot pedal is depressed to the desired ground speed. To unlock the foot pedal, the operator can tap the foot pedal, press the lock button or press the brake pedal.
Efficiency Manager is automatically enabled in 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.
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.
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.
The cornerpost display shows the commanded gear instantaneously once selected.
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:
The transmission can skip a gear when operating under load by double bumping the shift lever.
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 7R Tractors default to 9F 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.
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.
The 7R, 8R, and 8RT Tractors feature two lighting package options:
1. Six front grill-mounted halogen lights
2. Twelve cab roof-mounted halogen lights
3. Two rear fender-mounted lights
4. Two rear turn signal and brake/tail lights
5. Two front corner lights and two belt-line lights
6. Left-hand rotary beacon light
All halogen lights will be replaced by light-emitting diode (LED) lights
7. Two extremity lights*
8. Two loader/driving lights
9. Right-hand rotary beacon light
* Base for some markets according to the legal requirements.
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 economy and 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 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 high-intensity discharge (HID) lights which lead to lower costs of ownership throughout the life of the tractor.

The low- and high-beam driving/work lights are adjustable. Please refer to the operator’s manual section Electrical Services for complete details on adjusting lights.
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 and control.
There are four key features of the ACS system:
Dynamic road wheel offset control:
Variable ratio steering:
Elimination of steering slop and hand wheel drift:
Variable effort steering:
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 has the ability to 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 fails, 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. There is a backup for ACS components.
The ACS system consists of several key components:
