4044R

The bold styling of the 4M and 4R Tractors provide an attractive and functional appearance similar to that of the larger agricultural tractors. Benefits of this styling include:

• Easy tractor family identification
• Updated fixed grille and side panel hood design allows for optimum sealing of the cooling compartment
  • Front grille slides up to an integrated maintenance position for easy battery access
• Easily removable cowl, allowing for serviceability access
• Wraparound-style light-emitting diode (LED) headlights
  • Premium integrated automotive style headlight bezels
• Bold graphics
• Aggressively sloped hood design, giving a softer, smoother look and providing improved visibility
• Hybrid exhaust in base on cab tractors for clear operator visibility and safety
  • At low speed and when tractor is in a filter cleaning process, exhaust will be routed through vertical exhaust outlet. In all other cases, the exhaust will be routed through the downward exhaust outlet.
  • Side exhaust in base on open operator station tractors and ensures minimal heat impact to operator

The result gives the tractor a distinctive appearance and feel.

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

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. It meets EPA Final Tier 4 (FT4) emission standards.

The engine uses the latest technologies 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 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.

The tractor comes 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 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 starts with one or both foot pedals depressed, but it does not move until both pedals first return to neutral.

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

Key John Deere advantage

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 an easier and more comfortable experience.

eThrottle

Press a button to activate/deactivate eThrottle. When eThrottle is activated, depression of the 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

An automotive-style cruise control is standard equipment on the 4M Heavy-Duty and 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/maximum speed
  • Use the RES/+ button to set cruise speed, or to increase cruise/maximum 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 is a standard feature on the 4M Heavy-Duty and 4R Series Tractors.

 

If torque requirements increase significantly, the transmission reduces 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
 

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.

This icon indicates longer accelerate and decelerate distances.

This icon indicates shorter accelerate and decelerate distances.

SpeedMatch

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 maximise productivity.

• Retractable seat belts prevent belts from becoming tangled in seat suspension and controls.

Hitch assist (ground positioning)

The hitch assist feature allows the operator to creep the tractor backward or forward while standing behind the tractor. Engaging and operation includes the following steps: 

• Ensure hitch assist switch is in off position (A below)
• Engage the park brake
• Select A range
• Set to low throttle
• Ensure power take-off (PTO) is off
• Operator must be in the tractor’s seat
• Activate the hitch assist switch
  • If successful, flashers will trigger
  • If not, the missing interlock will be displayed on the LCD screen
• Once flashers are triggered, if the operator leaves the seat, the display will beep indicating that the hitch assist is in remote mode
• Operator moves to back of the tractor, start motion of the tractor using the enable button (B below) and corresponding direction button (C below)
  • Push and hold both buttons continuously as long as motion is desired
• Audible alarm will sound indicating motion of the tractor

Auxiliary 3-point hitch control

The auxiliary 3-point hitch control on the left-hand fender allows the operator to raise or lower the hitch while standing on the ground behind the tractor.

Pairing the auxiliary 3-point hitch control with hitch assist, changing implements has never been easier. Both features are in base equipment for 4R Series eHydro™ transmission models.

Electrohydraulic (EH) hitch control operation

The EH Hitch control provides more operator comfort and precision when moving the hitch up and down. It enables the operator to set both an upper and lower limit.  Hitch depth can be set from 0 -9.  Zero being the highest and can be locked for transport.  9 is the lowest setting.  Electronic controls also offer a quick raise and lower function. 
 
The adjustable depth stop provides consistency when lowering the hitch. Each time the position control lever is pushed forward, it stops where the depth stop has been positioned. This feature is a value to anyone who desires a consistent, level ground, like when preparing a seedbed. 

A – Position Control Lever Stop - Push down and rotate wheel (A) until stop sets to desired working depth. Implement returns to set depth when position control lever is pushed forward to contact stop. A few minutes of implement operation helps determine the best depth. To lower hitch below the preset depth stop, lift position control lever (B) and push forward past stop.
B – Position Control Lever - Position control lever controls raise or lower movement of rear hitch-mounted implement and ground depth penetration. Pull lever rearward to raise and push lever forward to lower.

• Transport: Pull lever full rearward past “0” to transport implement. Ensure that lever is in transport lock position (lever flipped over latch at the padlock symbol).

C – Quick Lower Button - Depress the quick lower button (C) to return the hitch to the set working depth. Hold down quick lower button (C) while machine is moving for 1 second to activate quick raise/lower feature.
D – Quick Raise Button - Depress quick raise button (D) to raise the hitch to the upper limit setting
E – Upper Limit Adjustment Control Knob - Turn knob to set the maximum raised position of the hitch. This allows the operator a means to adjust the maximum height to which the hitch moves when a raise command is executed.
F – Rate of Drop Adjustment Control Knob - Turn knob to set the rate at which the hitch lowers. This allows the operator a means to adjust the rate at which the hitch moves when a lower command is executed.

EH Hitch Raise & Lower Buttons

The optional field-installed 540/540 economy power take-off (PTO) allows operators to select the engine rpm needed for their PTO application. The economy position provides 540 rpm to the PTO at approximately 70 percent of the engine's normal rated speed. The engine runs at a rated speed of approximately 1750 rpm in the 540 economy position. The 540 economy is ideal for any PTO application, from running a mower to a baler or a cutter, where full horsepower is not needed. Operating at lower engine rpm decreases fuel costs during tasks. The overall operating experience improves because there is less noise and vibration for the operator.

 

A conveniently located lever (behind the seat of the tractor) allows the operator to simply change between 540 and 540E when conditions merit the opportunity to save fuel without affecting performance. For heavy-duty operations that require maximum PTO power, the PTO shift lever is placed in the 540 position, the PTO engaged, and the engine is run at rated speed of 2400 rpm. This selection gives 540 rpm to the PTO shaft and delivers the full-advertised horsepower at rated engine speed.

The 540/540 economy PTO offers all the features of the standard 540-rpm PTO, and the safety interlock is a foolproof measure provided to compensate for operator oversight. When the tractor is in economy, the engine is limited to a lower operating speed, preventing accidental over speeding of PTO implements and protecting against binding the PTO shaft. The safety interlock also prevents accidental shifting of the PTO selector lever at higher engine speeds than the economy PTO setting, which would lead to downtime to fix implements or drivetrains. Please note that economy PTO is only applicable to 4066R.

Regular service and maintenance are essential to the performance, productivity, and longevity of the tractor.
