Guidance solutions
AutoTrac ready
John Deere AutoTrac system provides a hands-free guidance solution, helping to manage in-field efficiency and greatly reducing operator fatigue. The 6R Tractor comes from the factory as AutoTrac ready, which includes the software, sensors and valves to provide an integrated solution for the producer (receiver and activation are purchased separately). This allows producers to capture the value of guidance without the installation of labor-intensive kits.
AutoTrac Turn Automation
AutoTrac Turn Automation controls the entire headland turn and manages all tractor and implement functions, including forward speed changes and power take-off (PTO) switching. It raises or lowers the hitch or activates selective control valves (SCVs) at exactly the right time and position in the field to guarantee perfectly consistent headland crop growth.
AutoPath™ system
AutoPath automatically creates guidance lines for different width machines based on data gathered by the first pass of a tillage implement or planter. It takes charge of your guidance line management, protecting nutrient investment and helping you make each pass with confidence and precision. If you are using different width implements for planting, spraying, or harvesting, AutoPath ensures the tires always follow the planted rows and stay off the crop. When harvesting, the combine is always guided to the correct starting point, and the guidance lines are automatically calculated based on the width of the header.

Comfort and maneuverability
Operate the 6R Tractor with ease
Operator Comfort
Triple-Link Suspension (TLS™)
TLS suspension
The TLS Plus system provides optimal traction and field performance by maintaining ground-to-tire contact, enabling more power to the ground. It also ensures higher operator comfort, reduces operator fatigue, and increases productivity, while the Variable Ratio Steering improves in-field maneuverability.
Cab suspension
Cab suspension system
The intelligent hydropneumatic cab suspension offers more driving comfort in the field and on the road. Input from the acceleration and TLS sensor causes the cab suspension controller to increase or decrease the amount of oil in the shock absorber ram. This semi-active system delivers ultimate comfort in every situation.
Variable Ratio Steering
Variable Ratio Steering off
Variable Ratio Steering on
Variable Ratio Steering improves operator comfort, requiring less hand movement and less steering effort when turning on the headland or in confined spaces. This results in faster turning of the steering wheel and increases hydraulic flow, leading to a quicker response from the tires. The system can be activated or deactivated in the CommandCenter™ display and is available for all 6R Tractors.
Engine performance
Engine
The high power output of the John Deere 4-cylinder, 4.5L (274.6-cu in.) engine and the 6-cylinder, 6.8L (415-cu in.) engine is made possible by refined, four-valve, high-pressure common rail (HPCR) technology with an injection pressure of up to 2500 bar (36,259.4 psi). The PVS engine in the 6R 175, 6R 195, and 6R 215 models is equipped with a variable geometry turbocharger (VGT) that boosts performance and efficiency consistently across the torque curve. The PSS engines (6R 230 and 6R 250) use a two-stage turbocharging system in which the VGT multiplies the pressure created by a fixed vane turbocharger.
Intelligent Power Management (IPM)
Intelligent Power Management (IPM) is a feature for many typical farming operations that use the rear power take-off (PTO) in high-power applications or the tractor as a transport vehicle. Operators who are looking for more power in non-stationary PTO and transport applications will be interested in the IPM feature. In high rear PTO power applications such as forage harvesters, rototillers, and beet or potato harvesting equipment or where heavy trailers, carts, or implements are moved to and from various locations, this feature provides significant additional capabilities. The solution improves productivity with more consistent ground speeds, quicker acceleration, and the ability to better hold desired transport speeds. All 6R Tractors have IPM in base equipment. Hydraulic IPM is available as a separate option to enable the IPM in applications resulting in high hydraulic loads.
Reversible fan
Reversible fan
Optimize engine performance in dusty environments by utilizing the optional reversible fan technology available on all 6R Tractors. The reversible fan allows the operator to quickly clean radiator screens from the comfort of the cab. By manually activating the system with a switch in the cab, the radiator fan blades blow out dust and debris away from the radiator. This enables the engine to run cooler, resulting in fuel savings, less downtime, and overall increased efficiency.
Hydraulics
Hydraulic system
The closed-center, pressure-and-flow-compensated hydraulic system in the 6R Tractors has been engineered for maximum durability and reliability by optimizing the number of hydraulic components and connections, which also makes it extremely efficient. The system in the 6R 230 and 6R 250 delivers a powerful 160 L/min (42.3 gpm) at 1500 rpm with enhanced operating characteristics. In a 6R Tractor, you get up to six electrohydraulic selective control valves (SCVs) with a pressure relief lever, logically clustered, and all iTEC™ capable. You can easily control flow rates and times from the cab with the CommandCenter™ display.
Hydraulic Intelligent Power Management (IPM)
As a supplement to power take-off (PTO) and transport applications, Intelligent Power Management also delivers additional horsepower for hydraulically driven implements. The Hydraulic IPM keeps tractor wheel speed constant during applications that use power-hungry hydraulically driven implements like slurry tankers, sprayers, or manure spreaders.
Transmission portfolio
AutoQuad™ transmission
6R Tractor
The AutoQuad transmission has all the benefits of the PowrQuad™ PLUS transmission with the added convenience of automatic gear shifting. It is available in 20F/20R and 24F/24R versions. With the EcoShift option, a transport speed of 40 km/h (25 mph) is maintained at only 1533 rpm, reducing fuel consumption and emissions.
Enhanced AutoPowr™ transmission – Infinite speed adjustment in all situations
AutoPowr/IVT transmission
AutoPowr/IVT is a hydromechanical transmission that delivers stepless and continuous power at speeds between 40 km/h and 50 km/h (25 mph and 31 mph). The AutoPowr transmission maintains the selected speed by automatically responding to changing load conditions. Once running at maximum road speed, engine rpm automatically drops to the minimum level required to maintain that speed, thus reducing noise and saving fuel. A speed of 50 km/h (31 mph) is maintained at 1630 rpm, and a speed of 40 km/h (25 mph) is maintained at 1300 rpm with the CommandPRO™ joystick.
DirectDrive transmission – The benchmark for seamless efficiency
DirectDrive transmission
Specifically developed for 6R Tractors, DirectDrive is an eight-speed, three-range transmission designed and engineered by John Deere for heavy agricultural work. Super-efficient dual-clutch technology always has the next gear lined up, so there is no lost momentum during changes, fuel consumption is reduced, and ease of operation is assured. During transport, DirectDrive reduces the engine speed to 1550 rpm at 40 km/h (25 mph) and 1600 rpm at 50 km/h (31 mph), thus reducing fuel consumption. In addition, the AutoClutch function enables you to stop the tractor without pressing the clutch.
Loader application
R Series Loaders
John Deere R Series Front Loaders have automatic latch designs, making the installation of loader and implements very efficient. John Deere loaders are built for productivity with little maintenance required. When combined with the maneuverability and technology of the 6R Tractors, operators enjoy proficient material handling and feeding in any application. An optional technology package boosts your productivity thanks to Return-to-Position and further enhances precision with the Dynamic Weighing System while preventing material losses thanks to the electronic Level-to-Horizon feature.
Electronic control with reverser
Optional electronic control
