On-screen help and diagnostic text
There are a few different ways to get meaningful on-screen help when navigating the Generation 4 CommandCenter. Operators can find the help icon on the shortcut bar on the bottom of every page. This icon gives detailed information on everything from tractor operation to application information. Simply select the help icon and navigate to the information section that is needed.
Additionally, application-based help is also available in all locations of the CommandCenter. Simply click on the (i) icon available on the title bar and it will lead directly to more information on the application currently being used.
Diagnostic text and information are available for better understanding of whether applications are operating as directed.
The machine monitor application provides the user instantaneous readings about the status or condition of the machine. Values shown in the machine monitor vary by application, but typically include parameters like engine speed, coolant temperature, and ground speed. The machine monitor supports run page modules in the layout manager, allowing the user to populate specific machine parameters directly to a run page.
NOTE: The machine monitor application replaces part of the Universal Performance Monitor in previous machines.
The work monitor application displays the performance information about the task being performed by the machine. The user is shown averages, totals, and productivity of the machine, such as area worked, average working speed, and fuel usage. The values of the work monitor can be reset by the user at any time. Specific values of the work monitor can be configured by the user to be shown on a run page.
NOTE: The work monitor application replaces part of the universal performance monitor in previous machines.
Tractors with a 4200 CommandCenter are equipped with one video input and tractors with a 4600 CommandCenter have two video inputs (one port to connect two cameras via a Y harness). The operator can set a variety of triggers, including reverse, PTO, hitch, and selective control valve (SCV) levers to activate the camera. The image will then appear on the CommandCenter display. The camera (video observation system) is available through John Deere Parts and Ag and Industrial (A & I) Products.

Infinitely Variable Transmission (AutoPowr™/IVT™) system
The John Deere Infinitely Variable Transmission (AutoPowr/IVT) utilizes a combination of mechanical and hydrostatic power, providing stepless and continuous power across an infinitely variable range of speeds.
Single-speed lever is used for intuitive and accurate control of ground speeds as slow as 50 m/h (0.03 mph) to 40/50 km/h (25/31 mph). In model year 2015, the transmission was revised so transport speeds are reached at lower engine rpms, ultimately reducing fuel consumption and in cab noise. Software has also been revised to ensure under acceleration engine rpm is kept to a minimum within the engines peak torque band.
- Easy to operate
- Four mechanical modes lead to excellent performance and reduced fuel consumption
- Revised ratios bring transport speeds at reduced engine rpm – reduced fuel consumption and increased comfort
- Precise management of forward speeds
- Less shifting time means better management of the implement
- Requires 240-amp alternator (code 8743) (6110R, 6120R, and 6130R)
- Requires code electrohydraulic (EH) selective control valves (SCVs) and 240-amp alternator
- Requires braked front axle (code 6070)
- Requires hydraulic trailer brakes (code 8756)
- Requires B-speed rated tires and front fenders (8011 or 8012)
50 KM/H (31 MPH)
The following features are part of the 50 km/h (31 mph) package:
- Triple-Link Suspension (TLS™) Plus system with brakes for improved braking capacity
- Rim and tire matching with fixed tread rims to minimize vibration and increase ride comfort
- Trailer brakes
- Front and rear fenders
Set-speed adjusting wheel
The set-speed adjusting wheel is the rotational thumbwheel located on the speed control lever. The wheel is quick and easy to adjust with the operator’s thumb and rotates infinitely with no stop or start position. When the operator rotates the thumbwheel, the ground speed of the tractor is increased by 0.2 km/h (0.12 mph) when the tractor is traveling below 20 km/h (12 mph). When the tractor is traveling above 20 km/h (12 mph), the tractor is increased by (1) km/h (0.6 mph). The set speed adjuster is used to set the maximum commanded forward or reverse speed in each speed band.
As the operator moves the lever within or between speed bands, the electronic management system ensures smooth, quick, and powerful acceleration or deceleration, regardless of load or ground speed.
While in motion, the operator can adjust the maximum speed of each speed band. With the lever in band one, the target maximum speed can be adjusted to 20 km/h (12 mph). With the lever in band two, the maximum speed of 40/50 km/h (25/31 mph) can be defined depending on transmission option. When stationary, all set speeds, both forward and reverse, may be adjusted while the left-hand reverser is in the power zero position.
- Quick and precise speed changes
- Fine-tuning via the speed wheel
- Two steps in the slot of the speed control lever to program two set speeds
- Speed feedback on the analog dashboard – the needle shows the actual speed, and red lights around the needle show the commanded speed
- Easy-to-handle exact-speed settings through the CommandCenter display and the speed wheel
An easy-to-use left-hand reverser is available in all the AutoPowr/IVT transmissions. The reverser control is located at the 10 o’clock position on the steering column for intuitive control. For tractors without the CommandPRO™ joystick, the left-hand reverser incorporates the following controls:
- Forward direction selector
- Reverse direction selector
- Park (P) - Park lock (P) - Tractor cannot move and the trailer brakes are engaged. Lever must be in the (P) park position to start the tractor.
- Neutral (N) – Tractor is in a non-parked position and capable of movement.
- Power zero – Tractor is held stationary by the transmission.
For tractors with CommandPRO, the left-hand reverser incorporates only forward and reverse direction selection and the lever is self-centering. The park (P) and neutral (N) positions can be selected on the CommandPRO.
- Tractors without CommandPRO allow for temporary stationary control of the tractor without using the brakes. For tractors with CommandPRO, ActiveZero is always in place when the tractor is not in N or P and brakes are not applied.
- Quick and easy way for the operator to change the direction of the tractor.
- Ensures that the tractor cannot be operated with the park lock on.
Electronic hand and foot throttle
The tractor ground speed is controlled via the accelerator and hand throttle. The engine rpm can be set to a specific ground speed using the hand throttle (A). The following functions are available for tractors without CommandPRO:
- Button (B) activates and de-activities the FieldCruise™ system (with two available pre-sets), which is an engine rpm limiter.
- The specific ground speed set can be set by pressing button (C); this pedal lock feature works like the cruise control on a car (only functions when foot throttle is ordered).
- Button (D) allows the operator to drive with the minimum target rpm with ECO on.
- NOTE: Button (D) is only active in custom mode.
The following functions are available for tractors with CommandPRO:
- Button (B) and (D) activate and de-activate engine set speeds that can be set in the CommandCenter display.
- Button (C) can be used to fix the engine speed command to the current hand throttle position (no automatic engine speed control).
- Define setting of the engine speed and its limit with the FieldCruise system
- Quick attainment of desired speed
- Pedal lock function allows command foot throttle speed to be maintained
AutoPowr/IVT selector control via CommandCenter display
The AutoPowr/IVT application setting employs four modes to take full advantage of the engine-transmission communication: full AUTO, custom, pedal and manual.
Full AUTO mode
Full AUTO mode enables the tractor to make adjustments to the transmission operating mode automatically, based on the engine and transmission speeds and the load on the tractor. This should be the AutoPowr/IVT transmission setting for 95 percent of all applications.
Full AUTO mode switches between load control and fuel economy mode seamlessly, with no involvement from the operator, as conditions and applications change. Fuel economy mode automatically switches off when the power take-off (PTO) is engaged to provide full PTO power. Operators can set the maximum forward and reverse speeds for the tractor in their particular application.
NOTE: Activation ECO is not available in full auto mode.
Custom mode allows the operator to customize the AutoPowr/IVT transmission settings when full auto mode is not desirable. In custom mode, operators can turn ECO on and off. This can either be done by pushing the ECO button on the side of the hand throttle module or by selecting ECO in the transmission settings page of the CommandCenter display. When accelerating with ECO on, the tractor minimizes engine speeds, which reduce acceleration aggressiveness. As a result, ECO on should reduce fuel consumption in lighter, steady loads. In contrast, when accelerating with ECO off, engine speed can be higher aggressively to maximize productivity. The higher engine speeds with ECO off better enable the tractor to quickly recover from sudden load increases and not lose as much ground speed when load increases occur.
In custom mode, the engine droop settings can be defined between 4 percent and 30 percent with PTO on and off. The higher the droop percentage, the more the engine rpm will be reduced when pulling before a transmission ratio change is made.
- Ensure that the operator has the best driving options when required
- Independent droop settings allow the operator improved performance and flexibility
Pedal mode settings
Pedal mode allows the operator to change the tractor’s ground speed independently from the engine speed. The ground speed is controlled through use of the foot pedal while the hand throttle determines engine speed. Maximum ground speed is determined by the location of the speed control lever in the speed band. Operators can lock-in a desired ground speed without pressure on the foot pedal using the pedal lock button (as described above). To unlock the foot pedal, the operator can tap the foot pedal, press the lock button, or press the brake pedal. When releasing the foot pedal, the vehicle decelerates to a safe creep speed. To come to a complete stop, the brake pedal should be depressed.
- Pedal mode is ideal for applications like mowing, baling, or hedge cutting, where it is important to keep the engine speed at a constant rpm independent from the ground speed.
Manual mode settings
Manual mode makes the transmission and engine independent of each other. The transmission does not automatically adjust engine rpm to save fuel. This can prove to be useful in applications like loader work, where the variability of engine speed based on load is not needed.
Load anticipation feature
The load anticipation feature allows the AutoPowr/IVT transmission to predict how much load the engine expects from the activation of the hitch or a particular SCV function.
In full AUTO mode, all load anticipation features are active. In custom mode, they can be turned on or off in the custom settings page. When an SCV or the hitch is activated, the engine speed is raised to 1500 rpm (as long as the commanded throttle position is over this value). This creates a boost in engine power which improves hydraulic performance and prepares the engine for potential load situations (for example, returning an implement to work). Also added is PTO load anticipation. If it is turned off, the engine does not react to PTO engagement and engine speed is controlled purely based on load. If turned on (in custom), when the PTO is engaged, the engine rpm will rise to throttle position or pre-defined PTO cruise setting.
- John Deere exclusive feature
- Tractor recognizes when additional engine rpm is needed
- Saves fuel, because the engine shuts down when no additional power is needed
Similar to the AutoQuad™ PLUS transmission, the AutoPowr/IVT transmission can also adjust the forward/reverse speed ratio. The reverse speeds can be set to a maximum of 30 percent higher and 70 percent lower than forward speeds, but only in range 1. In range 2, the forward-to-reverse speed ratio is 1:1, up to 22 km/h (14 mph). Above that, the reverse speeds will only go up to 30 km/h (19 mph).
Brake with integrated AutoClutch function
With the AutoPowr/IVT transmission, no clutching is required to stop the tractor. After the brakes are released, the tractor automatically accelerates back to its previous speed (if using hand throttle). The effect of AutoClutch can also be set via the CommandCenter display.
- This feature makes the AutoPowr/IVT an ideal transmission for operations that require a lot of speeds (like baling or loader work).
- Upon release of the AutoClutch, the tractor will accelerate to the previous command speed (ideal for round baling).
- Excellent modulation makes inching to implements and attachments easy.
The AutoPowr/IVT transmission is a combination of mechanical and hydraulic components that can provide low speed with extremely high levels of torque:
- Allows the tractor to smoothly pull away, even under high loads
- Enhances front loader operation by delivering high torque, driving the tractor into the pile without slippage
- Retains constant working speeds with PTO implements, which tend to push the tractor (spading or rotary cultivator)
Creeper mode is a standard feature on the AutoPowr/IVT transmission. Down to 50 m/h (164 ft/h), the creeper mode is activated when the selected speed is below 2.1 km/h (1.3 mph) in set position 1.
When the tractor moves below 600 m/h (1968 ft/h), the engine speed is independent of travel speed. This allows the operator to choose the engine speed that best fits the task (rated speed for hydraulic or PTO usage, or low idle for fuel-saving operation). No additional power is needed.
CommandPRO™ joystick driving strategy
The optional CommandPRO joystick combines a unique driving strategy with reconfigurable controls.
- 11 reconfigurable controls for both tractor and implement functions
- Possibility to operate tractor and ISOBUS functions at the same time on the CommandPRO joystick
- Intuitive and easy driving concept
The unique driving strategy is designed to deliver highest performance in combination with operator comfort making the daily work much easier and efficient.
- Pedal and joystick mode are active at the same time
- ActiveZero keeps the output speed actively at 0 km/h (0 mph) until command for acceleration is given independent of load or engine speed
- Command top and zero speed simply by one push or pull
- Unique inching control
- Three easily adjustable travel set speeds
- Two engine set speeds
- Three acceleration response settings
PEDAL AND JOYSTICK MODE ACTIVE AT THE SAME TIME
The change between using the foot pedal or the joystick can happen while driving for ease of use and comfort. The simple rule is: the higher speed command is superior. When changing from the pedal to the joystick, there is a short overlap where the joystick takes over the command from the pedal before the pedal is released. Similar, when changing from joystick control to the foot pedal, the driver needs to push the foot pedal to the point of speed where the joystick is before it can take over.
The inching control of the CommandPRO joystick simplifies the attachment of implements. Once the joystick is pushed into the inching range, the tractor moves very slowly in the selected direction. Speed is dependent on the joystick position and can be speed between 0 and 2 km/h (0 and 1.2 mph). Maximum speed of the inching range can be set to 5 km/h (3.1 mph) with the travel speed adjustment wheel.
Unlike the main range, releasing the joystick means the speed is reduced until the vehicle stops completely. This allows the operator to fully focus on the implement and quickly stop if required.
TRAVEL SET SPEEDS
The travel set speed buttons on the CommandPRO joystick allow the operator to set two set speeds. The operator has to preselect the desired set speed by pushing the travel set speed button 1 or 2 and once the joystick is pushed to the right, the set speed is activated and the travel speed will be adjusted until the set speed is achieved. Additionally, the operator can set a maximum travel speed through the travel speed adjustment wheel or in the CommandCenter™ display.
There are different ways to set or adjust the set speeds:
- In the CommandCenter display
- If current travel speed should be saved as a set speed, press and hold either one of the buttons for 2 seconds and the speed is saved
- When already using a set speed, it can be adjusted with the travel speed adjustment wheel
The operator can also set a dedicated set speed when changing the travel direction. For example, the tractor is driving forward at 10 km/h (6.2 mph) and for reversing the reverse shuttle shift speed is set to 5 km/h (3.1 mph). This means when the shuttle shift takes place, the tractor will accelerate to 5 km/h (3.1 mph) in reverse direction. This function can be turned on/off and set to the dedicated speed in the CommandCenter display.
The three settings for acceleration and deceleration with the CommandPRO joystick can be changed by pressing acceleration response button. Three light-emitting diodes (LEDs) next to the set button indicate the currently activated setting.
- Smooth acceleration and deceleration – one LED glows
- Normal acceleration or deceleration – two LEDs glow
- Rapid acceleration and deceleration – three LEDs glow
The settings influence the following:
- Characteristics of increase and decrease in speed for both CommandPRO joystick and foot pedal
- Speed change value when flicking the CommandPRO lever forward or backward (triggering).
- 0.2 km/h (0.12 mph) in slow acceleration mode
- 0.5 km/h (0.31 mph) in normal acceleration mode
- 1 km/h (0.62 mph) in rapid acceleration mode
- Acceleration characteristics when activating a travel set speed
- Tractor behavior when commanding a change in direction of travel
To ensure comfortable and reliable deceleration of the tractor with both the foot pedal and the CommandPRO joystick the tractor is equipped with unique technology. The engine overspeed protection ensures that both transmission and engine are not overloaded when decelerating. Additionally, the anti-jackknife technology compares wheel speed of front and rear wheels when decelerating through the joystick, as this means that the front brakes are not applied but only through the rear axle. If the front wheels are moving quicker, the transmission automatically adjusts to ensure the same wheel speed and avoid the jackknife situation.
PARK LOCK AND NEUTRAL
The park lock is disengaged automatically when commanding any direction of travel. Additionally, it engages automatically when the driver leaves the driver seat while the tractor is stationary. If the tractor is equipped with a trailer brake, this logic also applies for the trailer brake.
The buttons for the park lock and neutral position are next to the CommandPRO joystick on the CommandARM controls. There is no park lock or neutral position available in the left-hand reverser.
Rear-mounted selective control valves (SCVs)
To control a rear implement, up to six SCVs or five SCVs plus Power Beyond can be ordered (6145R-6250R). For (6110R- 6130R) up to five SCVs or four SCVs plus Power Beyond can be ordered. The SCVs can be controlled electrically. Up to four mechanical SCVs are available, in combination with Power Beyond. All mechanical or electrical SCVs feature four positions - neutral, raise, lower, and float.
- Release levers make disconnecting hydraulic hoses easy
- Relocated valves improve operator's visibility to the rear hitch
- Up to six rear SCVs give operators total flexibility
MECHANICAL CONTROL VALVES
The tractor may be equipped with one type of mechanical control valves: premium (450 Series).
Premium-couplers control valves also have an additional lock function (position 3), which holds the control lever in the raise or lower position until the pressure in the oil circuit has reached a predetermined value (e.g., when the control cylinder has reached its end position).
In position 2, the control lever returns to neutral as soon as it is released and is the setting for normal hydraulic operation.
If an implement is connected, pressure connection has to be connected to the lower coupler. With standard SCVs, a valve prevents sudden loss of pressure caused by leakage when the engine is shut off.
On premium SCVs, the likelihood of leakage is further diminished.
Premium mechanical control valve (premium)
- Position 1
- Position 2
- Position 3
- Hydraulic oil flow control
ELECTRICAL CONTROL VALVES
The tractor may be equipped with the premium (450 Series) control valves. All main characteristics can be controlled by the CommandCenter™ display.
HYDRAULIC CONTROL OPTIONS
Hydraulic set up
Shortcut button right-hand console
Simply push the hydraulic symbol on the right-hand side console or the CommandCenter and the CommandCenter display shows a setup menu to:
- Monitor valve status - detent, float, or neutral
- Adjust maximum flow and detent (combine for both direction or separate extent and retract adjustment)
- Time detent - this is particularly useful when repeat SCV operations are performed, such as lowering a mower-conditioner plow or cycling planter markers.
- Continuous flow detent - this is particularly useful when a hydraulic motor is used, such as on an air seeder.
SCV flow setup
SCV flow rate can be programmed between 0.04 and 10 allowing fine tuning for implements with different hydraulic requirement.
Behavior can be set between linear (red), progressive (green), or a combination (yellow) for exact flow modulation and precise valve management.
- Linear means that the distance travelled by the SCV/ICV corresponds to the distance travelled by the control lever/multifunction lever
- Progressive means that initially the distance travelled by the SCV/ICV is less than that travelled by the control lever/multifunction lever (giving a more sensitive start to the movement)
