Maximize productivity with an eHydro™ transmission

The tractor is available with a three-range electronic hydrostatic (eHydro) transmission.

  • Fluid under pressure transmits engine power to the drive wheels using a pump and motor
  • Functions both as a clutch and transmission
  • Provides high torque for startup
  • Reduces powertrain shock loads

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 the operator to select both directions of travel and speed with a touch of the toe.

Key features of the eHydro transmission:

  • Infinitely variable ground speeds, in each range, allow the operator to match the speed of the tractor to the job.
  • No clutching means fast and easy direction changes.
  • Twin Touch foot pedals provide quick and easy forward/reverse operation.
  • Cruise control is standard equipment:
    • Cruise control switch is located on the right-hand console for easy access.
    • Cruise control is electronically engaged and disengaged, which allows for precise setting of speed.
Danfoss eHydro transmission Danfoss eHydro transmission

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

  • Large forged trunnion shaft with larger support bearings that reduce vibration and noise

  • Center section made from ductile iron (much stronger than grey iron used in many competitive transmissions)

  • Transmission oil cooler cools transmission oil for longer transmission life

Safety features of the eHydro transmission include:

  • The tractor will start with one or both foot pedals depressed, but it will not move until both pedals first return to neutral.

  • Operator presence system means the tractor will come to a stop if the operator leaves the seat but will not shut off unless the power take-off (PTO) is also running.

Key John Deere advantage
Twin Touch foot controls Twin Touch foot controls

John Deere's Twin Touch foot controls offer key advantages over competitive hydro model tractors.

  • Some competitive hydrostatic tractors use a treadle pedal designed (toe-heel) foot control for operation of the hydro.
    • 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™ LoadMatch™, MotionMatch, eThrottle, and automotive-style cruise control pulls the maximum efficiency out of the eHydro transmission tractors. All these features are standard on the 4M Heavy Duty and 4R models and deliver customers an easier and more comfortable experience.

    • Disengage cruise control button
    • Briefly depress the reverse travel pedal
LoadMatch power management system
LoadMatch indicator LoadMatch indicator

LoadMatch is a standard feature on the 4M Heavy-Duty and 4R 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 minimizing stalls.


Controls automatically adjust LoadMatch compensation depending on the tractor’s application. PTO applications require less engine speed fluctuation, therefore adjusting 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, standard on the 4M Heavy-Duty and 4R Series Tractors, is located on the right-hand console. It offers seven settings for adjusting the rollout or decelerating when the pedal is released.

SpeedMatch indicator SpeedMatch indicator

SpeedMatch, standard on the 4M Heavy-Duty and 4R 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’s preset speed and press the Set button to lock the speed. From there, the operator can use the automotive-style cruise controls to adjust 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 maximize productivity.

The engine uses the latest technology to optimize fuel economy, improve control and accuracy, and reduce 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 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.

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 have 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.
