The engine uses latest technologies to optimize fuel economy, improve control and accuracy, and reduces environmental impact.
The common rail system (CRS) optimizes fuel economy and reduces operating costs*. High pressure injection atomizes fuel into finer particles which burn more completely. It results in improved fuel economy and lower cost of operation.
The electronic control unit (ECU) provides optimum fuel control and accuracy. ECU monitors and controls the engine. It continuously monitors engine conditions and adjusts the fuel delivery accordingly to ensure optimum performance and emissions.
The engine comes with an aftertreatment system. The system operates automatically. The exhaust filter consists of a diesel particulate filter (DPF) which captures particulate matter (PM) contained in the exhaust gas. Using a natural cleaning process, most of the PM trapped in the exhaust filter is eliminated by the heat of the exhaust stream generated by normal use. In situations of low temperature, engine speed or load factor, an active cleaning cycle is initiated. In this cleaning cycle, the exhaust gas temperature is raised by injecting additional fuel during the exhaust stroke of normal vehicle operation to the diesel oxidation catalyst (DOC).
After many hours of use, the exhaust filter may require an ash removal service.
NOTE: *As compared to engines not using CRS technology.
Depending on the load that the tractor is under, as well as ambient temperature, humidity, and engine speed, the DPF may build up with particulate matter, thus requiring cleaning. Filter cleaning is determined by one of three conditions:
Once one of the three conditions has been met, filter cleaning will occur.
There are three different types of filter cleaning processes:
Passive filter cleaning
Passive filter cleaning occurs naturally when the engine is generating enough heat to oxidize particulate matter. This automatic process occurs continuously during normal operating conditions. No tractor icons or symbols appear on the display during passive filter cleaning.
NOTE: Passive filter cleaning requires no operator involvement, and there is no interruption to tractor operation.
Active filter cleaning
If conditions (temperature, load, or speed) for passive filter cleaning cannot be achieved, then PM is removed using active filter cleaner.
To achieve the required conditions, exhaust temperature management (ETM) manages the initiation and duration of active filter cleaning. ETM can adjust numerous engine parameters and/or inject a small quantity of fuel into the exhaust stream for a short duration. The fuel turns to vapor and chemically reacts with the catalysts in the DOC to create heat to oxidize PM.
It is important to note that at no time is the fuel in the DOC/DPF ignited, and there is no flame within the DOC/DPF.
Like passive filter cleaning, active filter cleaning requires no operator involvement, and there is no interruption to tractor operation.
Parked filter cleaning
In some instances where passive and active filter cleaning have not fully cleaned the PM from the system, a parked filter cleaning may need to take place. Most likely, the only time a parked filter cleaning will need to occur is when automatic filter cleaning has been disabled for an extended period of time and multiple warnings to engage filter cleaning were ignored or if the tractor has been used during light load conditions. Additionally, when the automatic filter cleaning process has been deliberately interrupted multiple times, or if active filter cleaning has failed numerous times due to a failed component, a parked filter cleaning may be requested. In these rare instances the operator will have to park the tractor and start the filter cleaning process.
The parked filter cleaning process needs to be activated based on usage and operation of the tractor. The process will take approximately 30 minutes. See operator’s manual for more details.
This system constantly monitors the soot level of the tractor, making sure the tractor is always in peak performance condition. This ensures high performance at all times.
NOTE: Number of hours since last regeneration and soot level percentage viewable on LCD display.
NOTE: When the tractor is in a filter cleaning process at low speed or while parked and running, the exhaust will be routed through the vertical exhaust outlet. In all other cases, the exhaust will be routed through the downward exhaust outlet. This ensures minimal heat impact to operator.

Twin Touch foot controls
John Deere's Twin Touch foot controls offer several key advantages over competitive hydrostatic transmission (HST) tractor models.
Key advantages over competitive HST tractor models:
Integrated eHydro features
The eHydro convenience controls have been integrated into a single module. Combining features such as SpeedMatch™ LoadMatch™, MotionMatch, eThrottle, and automotive-style cruise control pulls the maximum efficiency out of the eHydro transmission tractors. All of these features are standard on the 3R models and deliver an easier and more comfortable user experience.
eHydro convenience control module
eThrottle indicator
The 3R Series Tractors come equipped with the eThrottle function. This feature is designed make the tractor quieter and use less fuel. With the simple push of a button, the engine speed will be linked to the pedal position. The operator can keep the throttle essentially all the way in the low position. The engine rpms, as well as the tractor speed, will increase together with the pedal position. This provides the operator with comfort and convenience as well as fuel economy.
Cruise control indicator
An automotive-style cruise control is standard equipment on the 3R Series Tractors. Cruise control is electronically engaged and disengaged and is located on the right-hand operator console.
LoadMatch indicator
LoadMatch is an industry exclusive and a standard feature on the 3R Series Tractors.
If torque requirements increase significantly, the transmission will reduce the tractor's drive speed to compensate for the increased load on the transmission, maximizing torque to drive wheels and minimise stalls.
Controls automatically adjust LoadMatch compensation depending on the tractors application. PTO applications require less engine speed fluctuation, therefore adjusts the amount of droop depending on PTO speed. This adjustment increases efficiency and optimizes engine speed and torque output based on tractor application.
While typically left on, LoadMatch can be turned off with the right-hand console controls.
MotionMatch indicator (A)
MotionMatch indicator (B)
MotionMatch, standard on the 3R Series Tractors, is located on the right-hand console. The icon indicates longer (A) or shorter (B) accelerate and decelerate distances. It offers seven settings for adjusting the rollout or decelerate when the pedal is released.
SpeedMatch indicator
SpeedMatch, standard on the 3R Series Tractors, further enhances the eHydro cruise control functions by allowing the operator to preset maximum speed. Once this feature is engaged, the operator must stroke the travel pedal fully to meet the operator preset speed. This function will improve accuracy and safety, particularly at lower travel speed applications.
Rotary tilling or spraying applications are examples of where SpeedMatch can be applied. SpeedMatch will work in both the forward and reverse set speeds.
NOTE: Automotive-style cruise control and SpeedMatch can be used in conjunction with LoadMatch to Maximise productivity.
