NOTE:  If the tractor is equipped with an optional field-installed vertical exhaust, the exhaust pipe must be removed before opening and closing the hood of the tractor.

Built-in safety features for operator peace of mind 

Safety is designed into all 4M and 4R Series Tractors.

• Operator presence system ensures the operator is in the seat to run the tractor
  • If the operator leaves the seat when front or rear power take-off (PTO) is engaged, the engine shuts down.
  • For stationary PTO work, the tractor must be in neutral and the park brake fully set.
• The rollover protective structure (ROPS) is designed for operation safety
• Reflective ROPS strips for better tractor visibility
• Key switch interlock prevents bypass starting
• Visual PTO warning light alerts operator when rear PTO is running
• Placing the transmission in neutral and setting the park brake allows operator to run rear PTO safely when off the tractor seat
• Light equipment fulfills EEC road homologation requirements. (NOTE: EEC road homologation requirements not applicable for Australia/New Zealand). 

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

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 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 for fast and easy direction changes
• Twin Touch foot pedals for 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

Sauer-Danfoss eHydro transmission

Sauer-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 - 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

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

• Some competitive hydrostatic tractors use a treadle pedal (toe-heel) design 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™(eThrottle 4066R only) and automotive style cruise control pulls the maximum efficiency out of the eHydro transmission tractors.  All of these features are standard on the 4R models, and deliver customers an easier and more comfortable experience.

eHydro convenience control module

eThrottle (4066R only)

eThrottle indicator

Press a button to activate/deactivate eThrottle. When eThrottle is activated, depression of travel pedal increases engine rpm and tractor speed simultaneously. 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 4R 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, the operator is able to 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 a standard feature on the 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

The MotionMatch, standard on the 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.

MotionMatch indicator

Longer accelerate and decelerate distances.

MotionMatch indicator

Shorter accelerate and decelerate distances.

SpeedMatch™

SpeedMatch indicator

SpeedMatch, standard on the 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, aerating, 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.

Powerful Yanmar engine

The Yanmar diesel engine has a high-torque reserve that provides plenty of power under heavy load.

This 4-cylinder engine features lower levels of exhaust emissions and reduced noise levels.

The engine meets all current emission requirements for Stage IIIB (IT4) (4049R) and Stage IV (FT4) (4066R) emission standards.

DPF cleaning (4066 M/R only)

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.
