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 compared to engines not using CRS technology. 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 new engine comes with an after treatment 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.

DPF CLEANING

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:

• A prescribed time-based estimation of needed filter cleaning
• DOC/DPF pressure sensors
• A particulate matter buildup estimation based on load 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
• Active filter cleaning
• Parked filter cleaning

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.

Maximize productivity with an eHydro™ transmission

The 3R Series Tractor is available with an exclusive three-range electronic hydrostatic (eHydro) transmission.

• Fluid under pressure transmits engine power to the drive wheels through a pump and motor
• Provides high torque for start-up
• Reduces powertrain shock loads

Sauer-Danfoss® supplies both the pump and motor. This ensures that the components are matched to each other, providing maximum efficiency.

The electronic hydrostatic transmission is ideally suited for jobs where productivity is a must, such as loader or mower applications.

Twin Touch™ foot controls allow selecting both direction of travel and speed with a touch of the toe.

Key features of the eHydro transmission are:

• Infinite ground speeds, even at full throttle, allow the operator to match the speed of the tractor to the job
• No clutching for fast and easy direction changes
• Twin Touch foot pedals for quick and easy forward/reverse operation
• Cruise control is base equipment
  • Cruise-control switch is located on the right-hand console for easy access
  • Cruise control is electronically engaged and disengaged and allows for more precise setting of speed

Sauer-Danfoss eHydro transmission is used for reliable operation. Durability features include:

1) Large forged trunnion shaft with larger support bearings to reduce vibration and noise.

2) Center section made from durable cast aluminum, which is 10 percent stronger.

3) Transmission oil cooler cools transmission oil for longer transmission life.

Safety features of the eHydro transmission include:

• The tractor starts with one or both foot pedals depressed, but it does not move until both pedals first come to neutral.
• The tractor comes to a stop if the operator leaves the seat, but the engine does not shut off unless the power take-off (PTO) is also running.

• 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:

• Some competitive hydrostatic tractors use a treadle pedal (toe-heel) design foot control for operation
• Requires the operator to use both toe and heel to change direction, resulting in increased operator fatigue.

• Integrated eHydro features

• The eHydro convenience controls have been integrated into a single module. Combining features such as SpeedMatch™ cruise control, LoadMatch™ switch, MotionMatch, eThrottle, and automotive style cruise control pulls the maximum efficiency out of the eHydro transmission tractors. All these features are standard on the 3R models and deliver an easier and more comfortable user experience.

  eHydro convenience control module

  ETHROTTLE

  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 is 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, increase together with the pedal position. This provides the operator with comfort and convenience as well as fuel economy.

  AUTOMOTIVE-STYLE CRUISE CONTROL

  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.

• Maintains desired forward speed without pressure on the foot pedal
• When activated, operator can set cruise speed
  • Use the SET/- button to set cruise speed, or to decrease cruise/max speed
  • Use the RES/+ button to set cruise speed, or to increase cruise/max speed
• A speed sensor also allows the tractor to maintain preset speed driving up and down hills
• To disengage the cruise control, either:
  • Apply pressure to the brakes
  • Disengage cruise control button
  • Briefly depress the reverse travel pedal

• LOADMATCH POWER MANAGEMENT SYSTEM

  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 minimize stalls. 

   

  Controls automatically adjust LoadMatch compensation depending on the tractor’s 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
   
  MotionMatch, standard on the 3R Series Tractors, is located on the right-hand console. It offers seven settings for adjusting the rollout or decelerate when the pedal is released.

  MotionMatch indicator

  Longer accelerate and decelerate distances.

  MotionMatch indicator

  Shorter accelerate and decelerate distances.

  SPEEDMATCH

  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 improves 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 maximize productivity.
