#

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.

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.

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 12/12 PowrReverser transmission is available on the 4M and 4R Tractors.

The PowrReverser transmission offers a hydraulically shifted forward-to-reverse transmission. This allows for clutchless shuttle shifting between forward and reverse with one lever for quick and easy direction change.

  • PowrReverser transmission does not require the operator to use the clutch to shift between forward and reverse

The PowrReverser transmission features a hydraulically actuated wet clutch. Two multi-disk clutch packs (one forward and one reverse) are hydraulically engaged when the directional (reverser) lever is placed in either the forward or reverse position.

Each clutch pack consists of three large, 5-in. diameter clutch disks that operate in oil and are oil-cooled, allowing excellent heat dissipation and extended clutch life.

Forward/reverse clutches Forward/reverse clutches
  • Clutch A is used for the forward operation of the tractor
  • Clutch B is used for the reverse operation of the tractor

 

Key features of the PowrReverser transmission:

  • 12 forward/12 reverse (12F/12R) speeds
  • Reverser lever, located on the left side of the instrument console, allows the operator to make direction changes without clutching

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 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
Optional cruise control
Optional cruise control on 4M Tractors Optional cruise control on 4M Tractors
#

 A true-speed cruise control is optional equipment on 4M Tractors with eHydro transmission. Cruise control is electronically engaged and disengaged and is located on the operator console to the right of the operator.

  • Maintains desired forward speed without pressure on the foot pedal
  • Cruise control is set by engaging the switch when the desired speed is reached
  • 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 turn brakes opposite the eHydro pedals
    • Disengage cruise control switch
    • Briefly depress the reverse control pedal
LoadMatch™ power management system

LoadMatch is a standard feature on the 4M 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 through the center console display.

MotionMatch™ system

MotionMatch, standard on the 4M Series Tractors, is adjustable through the center console display. It offers variable adjustments to either lengthen or shorten the rollout when the HST pedal is depressed or released.

One of the greatest customer concerns involves difficulty in attaching tractor implements. John Deere has addressed this issue with the iMatch Quick-Hitch.

The iMatch Quick-Hitch provides easy hookup and a guaranteed fit for all Category 1 implements that are designed to meet the ASAE Category 1 Standard S278.6 for quick-attach hitches.

  • All implements require a set of bushings in order for the attachment to fit and work properly with the iMatch Quick-Hitch. One set of bushings comes with the iMatch Quick-Hitch.

NOTE: The bushing set can be seen in the picture above. These bushings allow the hooks on the iMatch and the pins on the implement to fit together properly. All other implements (box blades, tillers, rear blades, etc.) will require a set of bushings to enlarge the pin to fit with the iMatch hooks. Bushings of different lengths can be found in the parts system or through a bushing supplier (see dimensions below).

  • Upper bushing
    • Inside diameter: 1.93-1.06 cm (0.76-0.77 in.)
    • Outside diameter: 3.15 to 3.43 cm (1.24-1.25 in.)
  • Lower bushings
    • Inside diameter: 2.24 to 2.26 cm (0.88 to 0.89 in.)
    • Outside diameter: 3.63 to 3.66 cm (1.43 to 1.44 in.)
Excellent serviceability reduces operational costs and improves productivity

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

  • Easy access to regular service points minimizes service time.

Awesome Product!

We finally upgraded to a 4066M after having older smaller John Deere utility tractors and this on out does them all. Have used the tractor for tilling, 3-point mower, 3-point blade, and loader work. Engine has plenty of power. Zero issues with exhaust regens, just simply do it as the tractor asks. We chose the eHydrostatic option and couldn't be happier. All in all its a great all around tractor for the money, and we would definitely recommend.

Pros:

  • ease of use
  • great power
  • reliable

4066m

I haven't logged many hours yet and will try and update at a later time but so far I love my new 4066m. Regarding the regen... so far so good, my dealer suggested to try and run a minimum of 1800 rpm to keep the soot levels lower. At 1800, its louder than I would like while doing light work, but operates very very well at that RPM, just something that I will have to get use to. I got the HST transmission which is extremely easy to use and the large 66hp engine seems to have gobs of pto power. I would suggest to ask your dealer about getting the H180 loader with the controls closer in at the seat instead of the included 170. The 170 loader has the controls mounted on the loader and requires you to hold your arm out and "reach"...the H180 is waayy more comfortable. It also allows you to detach the loader and bucket more easily. All other tractor controls seems to be well placed and easy to use. I love the internal fender mounted toolbox! I listed the "value" as being fair...w/o the large rebate at the time I feel it might have been priced too high. All in all I am happy with my purchase and will recommend it in the future.

Avoid the tier 4 emissions

Dealer says I have to run it over 2000 rpms all the time otherwise it will clog the exhaust filter. with only 50hrs they want to tell me it will cost $800 to fix it because my average rpm use was too low. Not sure if common since factored in the engineering but that is a lot of power and wasted fuel at 2000 rpm to simply use the tractor around the yard. This machine did blow snow, mow, till and other big jobs but that apparently didnt keep the soot level down.
