Attractive styling provides improved visibility and serviceability

4R Tractor

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.

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.

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.

PowrReverser™ transmission allows for clutchless direction changes

PowrReverser transmission allows for clutchless direction changes

PowrReverser transmission lever

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

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
- Fast shuttle shift for improved loader operation
Dual-cone synchronizers allow for synchronized shifts between gears for on-the-go shifting with the use of the clutch
Dual-cone synchronizers permit on-the-go, low-effort shifting between gears
Helical-cut gears for quiet operation

Helical-cut gears

Well-spaced speeds for turf, loader, and transport work
Neutral start switch prevents tractor from starting when transmission (main range) is not in neutral
Dual wet-disk clutches provide long clutch life
Shifts between ranges are not synchronized
PowrReverser transmission models have both hand and foot throttle controls
Especially handy when using a loader

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® company 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 optional 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 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

Optional cruise control

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.

iMatch Quick-Hitch (LVB25976)

iMatch Quick-Hitch with rotary cutter hookup (LVB25976)

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.)
