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.Benefits
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 upShortcut 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:
SCV flow setupOverviewSCV 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.
Combination is an intermediate stage between the two settings listed above.
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, 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.
Instrumentation control panelOverviewThe 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:
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 pods. 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. The CommandCenter allows the operator to customize important tractor functions.This option requires a PowrQuad™ or AutoQuad™ transmission.

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.Key features:
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.Series turbochargers
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.
OverviewThe 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
OverviewAir-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
OverviewEvery 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)OverviewThe 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.
DetailsEach 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.
Light-emitting diode (LED)High-intensity discharge/Xenon (HID)Halogen (HB3)
NOTE: Please also see available attachments.Selecting the lighting mode
Operators can quickly select a lighting mode on the steering console by operating a rotary switch. The three 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.
More lighting informationOverview
Optional LED lighting technology provides better depth perception and pattern recognition as well as a natural low temperature light for excellent definition of the field. One LED light will out-live 200 or more incandescent lights, 55 or more halogen lights, and 14 or more HID lights.
OverviewBeltline and rear fender work lights provide options for full light flexibility, giving flood illumination exactly where the operator needs it. The John Deere beltline lights are available with HB3 work lights and LED work lights. The two rear fender lights are available in HB3 or LED.The John Deere lighting components have undergone numerous vibration testing procedures to ensure a good lighting performance and sturdiness under all conditions.All work lights and beltline lights are adjustable to a desirable angle.
