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.
NOTE: Not available in 6155RH.
|1552||AutoPowr/IVT – 50 km/h (31 mph)|
NOTE: Not available in 6155RH.
|1551||AutoPowr/IVT – 40 km/h (25 mph)|
The following features are part of the 50 km/h (31 mph) package:
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.
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:
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.
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:
The following functions are available for tractors with CommandPRO:
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.
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.
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.
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.
The AutoPowr/IVT transmission is a combination of mechanical and hydraulic components that are capable of providing low speed with extremely high levels of torque:
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.
The optional CommandPRO joystick combines a unique driving strategy with reconfigurable controls.

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.
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:
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.
The settings influences the following:
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.
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.
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.

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

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, diesel exhaust fluid (DEF) 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.
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.

The 6R Series features a redesigned CommandARM console with all key vehicle functions in one place. The updated CommandARM layout is only available with Infinitely Variable Transmission (IVT™) and DirectDrive transmissions. The base 21.3-cm (8.4-in.) 4200 CommandCenter™ Display or optional 25.4-cm (10-in.) (4600 CommandCenter Display is fully integrated onto the 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. (30 degrees right and 7.5 degrees left).
Hydraulic and hitch controls utilize fingertip paddle pots for raise/lower and extend/retract functions. The CommandARM offers up to a maximum of six electronic selective control valves (E-SCVs) (without electronic joystick). The optional electrical joystick replaces fingertip paddle pots 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 electronic joystick. For tractors with an IVT transmission, the CommandPRO™ joystick is available. Its 11 reconfigurable buttons enable the operator to have all necessary controls accessible without hand movements (for details, click here).
Controls for radio, lights, rotary beacon, and hazard flashers are located to the center right on the CommandARM along with 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. There are 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™ 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 auto steering angle dependent differential lock button.
Operators can easily identify controls by icons located near levers, and each functional area is color coded.
The right-hand control console is angled for operator comfort and ease of operation. The design of the right-hand console is controlled by the type of SCVs chosen.
Mechanically actuated valves are controlled by traditional levers, while electronically actuated valves are controlled by fingertip paddle pots. Controls for the ComfortView cab are grouped by function on the right-hand console.
The modular console panel provides individual access to hand throttle, transmission controls, MFWD switch (if equipped), hitch command console, load/draft control, SCV, and PTO controls.
The console is also the location of the CommandCenter display. The CommandCenter allows the operator to customize important tractor functions.
This option requires a PowrQuad™ or AutoQuad™ transmission.
The 6R Tractors have seven cab packages designed to match producers' operations. There are three levels of comfort - economy, standard, and premium.

John Deere 6R Series Tractors feature the reliable and proven PowerTech PVS 6.8L and PSS 4.5L and 6.8L engines. These air-to-air aspirated engines deliver a power bulge above rated power to provide excellent torque in demanding applications.
PowerTech PSS/PVS engine identification
To match the engine power characteristics and improve the operation economy of the machine, the rated engine speed is 2100 rpm.
The PowerTech PSS 4.5L and 6.8L utilizes two turbochargers – 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.
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.
Air-to-air after cooling
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.
HPCR fuel injection system
Every PowerTech PSS 4.5L and 6.8L engine utilizes a 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.
Engine control unit (ECU)
The ECU uses signal inputs from sensors and pre-programmed 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.
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:
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.
Lights on the 6R Series Tractors have been positioned and designed to provide maximum visibility to the front, sides, and rear of the tractor to increase productivity in any operating condition. 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.

Selecting the lighting mode
Operators can quickly select a lighting mode on the steering console by operating a rotary switch. The four settings available are:
The CommandCenter allows operators to customize two different light programs. The operator can switch between the two programs with the push button. Also standard on the 6R Tractors is the battery power-saver feature.
When the engine is off and the outside lights have been left on, this feature is designed to avoid battery run-down. After the lights have been left on for 30 minutes and the key is in the off position, the lights will cycle, or blink on and off five times as an alert. The lights will continue to illuminate for one more minute and then automatically shut off to protect the battery.
Additional lighting is available to match various applications and ensure maximum around-the-clock productivity. Optional LED lighting technology provides extreme brightness and a daylight color output for excellent definition of the field.
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.
One beacon light is mounted on the front of the cab to provide a rotating warning light for road traveling and added visibility.
CommandCenter™ console 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-tire contact, enabling more power to the ground.
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).
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.
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 touchscreen 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.
First link: vertical linkage
Two double-acting hydraulic cylinders control the vertical movement of the axle, which leads to excellent sensitivity.
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 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 leveling 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.
