Attractive styling provides improved visibility and serviceability
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 halogen 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.
Save fuel, reduce noise, and increase engine life with the economy power take-off (PTO)
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.
Hitch assist, auxiliary 3-point hitch control, and optional iMatch™ Quick-Hitch for easy implement hookup
HITCH ASSIST (GROUND POSITIONING)

Powerful Yanmar® diesel engine delivers plenty of power under heavy loads
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. It meets EPA Final Tier 4 (FT4) emission standards.
*Engine hp (kW), gross SAE J1995: 43.1 (31.7) at 2600 rpm, PS
Gross engine ps*
Displacement, cu in. (L):134.25 (2.2)
*Engine hp (kW), gross SAE J1995: 51.5 (37.9) at 2600 rpm, PS

*Engine hp (kW), gross SAE J1995: 65.9 (48.5) at 2600 rpm, PS
Displacement, cu in. (L):128.15 (2.1)
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*. 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.
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:
- 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.

- 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™ 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.

LOADMATCH™ POWER MANAGEMENT SYSTEM
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.
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.
Longer accelerate and decelerate distances.
Shorter accelerate and decelerate distances.
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 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.
