Machine Features
Infinitely variable transmission (AutoPowr™/IVT™ transmissions)
Overview
The John Deere 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 km/h (31 mph) to 40/50 km/h (25/31 mph). For Final Tier 4, the transmission has been 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.


Benefits
- 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

Set-speed adjusting wheel
Overview
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.




Benefits
- 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; red lights around the needle show the commanded speed.
- Easy-to-handle exact-speed settings through CommandCenter and the speed wheel.
Left-hand reverser
Overview
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 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.

Benefits
- 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 tractors 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 can’t be operated with the park lock on.
Electronic hand and foot throttle
Overview
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).
Following other functions are available for tractors without CommandPRO:
Button (B) activates and de-activates FieldCruise™ system (with two available presets), 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 other 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™ controls. Button (C) can be used to fix the engine speed command to the current hand throttle position (no automatic engine speed control).

Benefits
- Define setting of the engine speed and its limit with FieldCruise™ system.
- Quick attainment of desired speed.
- Pedal lock function allows command foot throttle speed to be maintained.
AutoPowr/IVT selector control via CommandCenter
Overview
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
Overview
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 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 applications.
NOTE: Activation ECO is not available in full AUTO mode.


Custom mode
Overview
Custom mode allows the operator to customize the AutoPowr/IVT 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.
When accelerating with ECO on, the tractor minimizes engine speeds, which reduces 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 of 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.


Benefits
- 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 previously command speed (ideal for round baling).
- Excellent modulation makes inching to implements and attachments easy.
Torque
Overview
The AutoPowr/IVT is a combination of mechanical and hydraulic components that are capable of providing 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 have a tendency to push the tractor (spading or rotary cultivator)
Creeper mode
Creeper mode is a standard feature on AutoPowr/IVT. 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.


Benefits
- Ensure that the operator has the best driving options when required.
- Independent droop settings allow the operator improved performance and flexibility.
Pedal mode settings
Overview
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.


Benefits
- 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
Overview
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
Overview
The load anticipation feature allows the AutoPowr/IVT to predict how much load the engine expects from the activation of the hitch or a particular selective control valve (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 a 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, returning an implement to work for example. 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.


Benefits
- 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.
Forward/reverse relationship
Overview
Similar to the AutoQuad™ PLUS transmission, the AutoPowr™ transmission/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
Overview
With the AutoPowr/IVT, 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 operator CommandCenter.
ComfortView™ cab operator environment
Overview
ComfortView cabs feature a modern, automotive-style instrument panel as base equipment. The instrument pod has two large analog dials for engine and tractor speed, as well as two smaller dials that display fuel level and coolant temperature. The steering column and dash are adjustable to suit the operator's needs. The column tilts toward the operator and a lever on the left-hand side allows for the column to telescope out to the desired level.
A dimming mode automatically reduces the brightness of the instrument illumination when the tractor lights are used.
Steering column control panel


Instrumentation control panel
Overview
The instrumentation panel has a row of information and warning lights across the bottom to monitor all important tractor functions. A three-stage warning system first gives information, then gives warnings, and finally, gives a stop alarm to prevent damage from occurring in the event of a component malfunction. An integrated power take-off (PTO) over-speed warning is incorporated into the diagnostics to ensure proper operation.


Dash instrument panel controls include:
Left side | Right side |
Left-hand reverser | Two-speed and optional intermittent wiper |

CommandARM controls
Overview
The 6R Series features a redesigned CommandARM with all key vehicle functions in one place.
The updated CommandARM layout is only available with AutoPowr™/IVT transmission and DirectDrive™ transmission.
The optional 17.8-cm (7-in.) (4100 CommandCenter™ display) or 25.4-cm (10-in.) (4600 CommandCenter) display is fully integrated on to CommandARM and offers fast adjustment of additional tractor functions.
The CommandARM design allows for 37.5 degrees of total seat swivel and adjustable positioning matching the operator’s preference.
Hydraulic and hitch controls utilise fingertip paddle pods for raise/lower and extend/retract functions. The CommandARM offers to a maximum of six electronic selective control valves (E-SCVs) (without electrical joystick). The optional electrical joystick replaces fingertip paddle pods for control of selective control vales (SCVs) and allows for programmable hydraulic functionality according to operator preference. (A maximum of five E-SCVs can be ordered with the electrical joystick.) For the 6230R and 6250R Tractors, the CommandPRO™ joystick is available. Its 11 reconfigurable buttons enable the operator to have all necessary controls reachable without hand movements (for details click here).
Controls for radio, lights, rotary beacon, and hazard flashers are located to the centre right on the CommandARM along with power take-off (PTO) for front (if equipped) and rear PTO. Additionally, located on the right side of the CommandARM is an encoder wheel which allows for finite positioning of the rear 3-point hitch. Three buttons near the encoder for set lock and return to height. Adjustment knobs for the 3-point hitch are located under the cover for the CommandARM storage compartment and allow for adjustment of the rate of drop, hitch height limit, and depth control.
The transmission control and throttle are placed on the left side of the CommandARM closest to the operator for convenient setting and adjustment. The throttle design incorporates buttons which control engine cruise speed, pedal lock/cruise control, and transmission Eco settings (for more information refer to the AutoPowr/IVT or DirectDrive transmissions pages).
Located just to the right of the throttle is the auto-steer activation button and four sequence controls for iTEC™ functions. Behind the iTEC sequence controls are buttons which control the activation and deactivation of mechanical front-wheel drive (MFWD) and differential lock.
Differential lock can also be activated by foot switch on the cab floor. A feature in the 6R Series Tractor is the auto-steering angle-dependent differential lock button.
Operators can easily identify controls by icons located near levers, and each functional area is colour-coded. The hitch control dials are available as a field installed attachment only. All adjustments can be done through the CommandCenter display.

Triple-Link Suspension (TLS™) Plus: More than comfort, it is a performance feature
More productivity - greater operator's comfort
CommandCenter™ controls
TLS Plus provides exclusive front suspension using a hydropneumatic self-leveling system to increase productivity and improve ride dramatically. TLS Plus provides more control over the front suspension of the tractor. In the field, the TLS Plus front suspension maintains ground-to-tyre contact, enabling more power to the ground.


Auto mode
The TLS Plus reacts to inputs, which provides the best comfort and stability. Inputs include travel speed, implement weight, draft characteristics, and braking activity. The TLS Plus activates whenever the tractor exceeds 1.5 km/h (0.9 mph).
Maximum mode
The suspension is set to maximum hardness, which is preferable for front loader operation. This allows the operator to adjust the suspension for different situations. If the tractor exceeds 35 km/h (22 mph), the hardness is reduced to provide greater driving comfort. When dropping below 25 km/h (15 mph), maximum is reactivated.
Manual mode
This setting can be useful when attaching mounted implements to the front hitch. When activated, the axle settles in its mid position and then can be raised or lowered manually with the touch screen or shortcut buttons F and G. The manual setting is overridden when the travel speed exceeds 5 km/h (3 mph) and returns to the previously selected setting of automatic or maximum.
The system
| First link: vertical linkage Two double-acting hydraulic cylinders control the vertical movement of the axle, which leads to excellent sensitivity. The 6230R and 6250R Tractors have larger cylinders so they are mounted diagonally on top of the axle for optimised performance in this horsepower class. |
| Second link: longitudinal linkage |
| Third link: lateral linkage This third link holds the axle laterally. These few simple components ensure excellent suspension quality and reliability with reduced maintenance. |


A. TLS Plus axle oil pressure sensor
B. Annular-chamber accumulator – tuned in conjunction with the compression accumulators and receives oil when the axle drops, such as when traveling through a dip or an implement is lifted. Control block (I) keeps the suspension in the mid position, this is monitored by a position sensor (E). The mid position allows a comfortable ride and good performance in all load conditions.
C. Priority 2 control block (supplies oil to the control block (I) which actuates axle raise and lower)
D. Front chassis control unit (processes inputs from pressure sensor (A) and position sensor (E) as well as data on the CAN BUS to provide the correct outputs to solenoids on valve block (I) to actuate axle movement)
E. Axle position sensor – providing inputs to the controller
F. Two accumulators allow the suspension effect by receiving oil, which is displaced from the cylinders when the axle is compressed.
G. Panhard link (stopping lateral movement)
H. Hydraulic cylinders allow vertical movement of the axle
I. Control block containing solenoid valves responsible for supplying oil to either annular or bore side of the cylinder allowing the suspension to lower or rise respectively. Inputs to the solenoids ensure the axle returns to the central position in all situations.
J. SFA controller software, the software reads inputs from the position sensor (E) and compares them to the known value for the mid position. If a position change is sensed for a prolonged period the solenoids in valve block (I) actuate to move the cylinder in the correct direction to find centre.
A full stroke of the suspension typically takes 1 second, allowing the system time to distinguish between typical terrain inputs or level changes. This prevents overreactions.
In addition to active central levelling of the suspension, the John Deere TLS Plus adopts a constantly variable rod side pressure by using a closed loop system. When the suspension reacts at a different frequency which could be detrimental to driver comfort, the system then fine-tunes the rod side pressure, changing the spring stiffness and improving the ride behavior.
The theory
Similar to kinematic linkage systems used in the automotive industry, the long horizontal draft member in conjunction with the suspension cylinders create a dynamic stability triangle which is a kinematic reacting system. Front axle bouncing from varying drawbar loads is automatically compensated.
The reaction forces excerpted by the pulling front axle are used to enforce piston rod travel of the suspension cylinders. The kinematics control the extension and retraction of the cylinders, which counteracts the bouncing movements of the front end.

The long draft linkage of the TLS Plus allows the virtual hitch point (VHP) of the rear three-point linkage to coincide with the mounting point of the horizontal linkage. This results in a more stable and consistent draft performance from the tractors centre of gravity, shown at left.


F - pull force on front axle
C - cylinder pressure
H - height of draft member bearing above ground
L - effective length of draft member
As the power being transmitted through the front axle to the ground increases (pull force [F]), the cylinder pressure (C) also rises, subsequently allowing the cylinders to retract. This eliminates the lifting motion of the front end, shown above.
A reduced power or pulling force (F) reduces the cylinder pressure (C) on the ground and the cylinder rods extend. This eliminates bounding or dipping down when the power is reduced.

Technology
|


Benefits
- A constant power range of 2100 rpm down to 1550 rpm
- Power bulge of 10 percent
- Greater tractor productivity
- Responsive power reducing the need to downshift the transmission
Details
To match the engine power characteristics and improve the operation economy of the machine, the rated engine speed is 2100 rpm.
Enhanced PowerTech PSS 6.8L engine in the 6230R and 6250R
The enhanced 6.8L PowerTech PSS engine has been developed to provide the best reliability and cooling capacity thanks to updated designs and advanced components. The cylinder head, engine block, and cylinder liner have been equipped with additional cooling technology to support the higher cooling requirements due to the higher horsepower and ensure long engine life. Additionally, the enhanced material technology allows reinforced pistons and crankshaft meaning more power density without compromising reliability.
Series turbochargers
Overview
The PowerTech PSS 4.5L uses a wastegate and a fixed geometry turbocharger while the PowerTech PSS 6.8L utilizes a VGT and a fixed geometry turbocharger, providing the torque rise and engine response needed to meet varying load conditions.
Fresh air is first drawn into the low-pressure fixed geometry turbocharger and compressed to a higher pressure. The compressed, higher pressure air is then drawn into the high-pressure VGT, where the air is further compressed. By splitting the work between two turbochargers, both can operate at peak efficiency and at slower rotating speeds.


Benefits
- Delivers high-power density
- More low-speed torque and responsiveness to meet varying load conditions
VGT
Overview
The VGT is electronically controlled and actuates the turbo vanes as required to maintain peak engine performance.
The turbocharger’s vanes are in the exhaust flow. The opening or closing of the vanes changes the outlet volume and airflow speed against the turbocharger turbine. When exhaust flow is low, the vanes are partially closed. This partial closure increases the pressure against the turbine blades to make the turbocharger spin faster and generate more boost pressure.
The ability to keep the airflow at optimum levels provides more consistent engine boost pressure and the ability to respond to load quickly across the entire engine rpm range. This system is without the turbo lag that can be found on some engines.


Benefits
- Optimized fluid economy
- Maximum engine performance
Details
Each injector is controlled individually by the ECU. The ECU turns the injector on and off during each firing cycle to control the fuel delivery into each cylinder.
Load and speed sensing allows each cylinder’s fuel delivery rate to be adjusted independently at the individual injector. With each injection cycle, the ECU can make the following adjustments on the go:
- Number of injections
- Fuel pressure in the common rail
- Start of injection
- Duration of injection
This management system is connected to the transmission, allowing the engine and transmission to respond simultaneously.
Cold weather and high-altitude compensation are also precisely controlled for quality starts regardless of weather and maximum performance at high elevations. The ECU also features improved diagnostic capabilities. It is faster, has more working memory, and is responsible for monitoring and executing all aspects of the integrated emission control system.


Benefits
- Increased low rpm torque
- Quicker response to load
- Increased peak torque
- Improved fluid economy
- Improved performance at high altitudes
Air-to-air after cooling
Overview
Air-to-air after cooling lowers the intake manifold air temperature and provides more efficient cooling while reducing cylinder firing pressure and temperatures for greater engine reliability. Since lower temperature air is denser, a higher volume of air flows into cylinders so the engine is capable of meeting the increasing horsepower demands. Lowering the intake manifold and cylinder temperatures also aid in lowering the combustion temperature, which lowers the NOx produced as a result.
Benefits
- Higher horsepower
- Less NOx production
HPCR fuel injection system
Overview
Every PowerTech PSS 4.5L and 6.8L engine utilizes a high-pressure common rail (HPCR) fuel system to efficiently supply fuel to injectors. The high-pressure fuel pump instantly responds to requirements for more or less fuel flow or pressure. This electronically controlled, high-pressure pump delivers pressure on demand according to the application requirements. Pressure on demand ensures an efficient injection system resulting in high injection pressure independent of engine speed.


Benefits
- Instantly respond to load changes reducing the need to change gears
- Improved fluid economy
Engine control unit (ECU)
Overview
The ECU uses signal inputs from sensors and preprogrammed performance modeling to control critical engine functions such as fuel quantity, injection timing, air-to-fuel ratio, multiple fuel injections, amount of cooled exhaust gas recirculation (EGR), and a host of other control parameters.
Rear-mounted selective control valves (SCVs)
Overview
To control a rear implement, up to six SCVs or five SCVs plus Power Beyond can be ordered (6145R-6250R). For (6110R-6135R) 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.

Mechanical control valves
Overview
The tractor may be equipped with two different types of mechanical control valves: standard (200 Series) and premium (450 Series).
Standard couplers control valves provide a lock function (position 1) which holds the control lever in the rails or lower position until it is moved manually.
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.

Electrical control valves
Overview
The tractor may be equipped with the premium (450 Series) control valves. All main characteristics can be controlled by the CommandCenter™ controls.

Example options of rear valve configuration



Hydraulic control options





Hydraulic set up
Shortcut button right-hand console
Overview
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)



Detent setup
Overview
- Time detent - this is particularly useful when repeat SCV operations are performed, such as turning a 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
Overview
SCV flow rate can be programmed between 0.04 and 10 allowing fine tuning for implements with different hydraulic requirements.
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 corresponds to the distance travelled by the control lever/multifunction lever
- Progressive means that initially the distance travelled by the SCV is less than that travelled by the control lever/multifunction lever (giving a more sensitive start to the movement)




Combination is an intermediate stage between the two settings listed above.
