The engine uses the latest technologies to optimize fuel economy, improve control and accuracy, and reduce environmental impact.
The common rail system (CRS) on the 4066M and 4066R 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. (4049M and 4049R comes with direct diesel injection)
The electronic control unit (ECU 4066 M/R) 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 (4066 M/R). 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 (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
- Passive filter cleaning
- Active filter cleaning
- Parked filter cleaning
- Lower rated speed for 540 rpm power take-off (PTO) operation means better fuel economy, less noise and vibration, and longer overall engine life
- Cast-in-block cylinder design for good cooling and long life
- Hydraulic lifters are quieter and require no adjustment
- Heavy-duty crankshaft provides more bearing surface area for added durability
- CRS optimizes fuel economy, lowering the cost of operation (4066M/R)
- ECU provides optimum control and accuracy (4066 M/R)
- Direct fuel injection (4049M/R)
- Improves starting
- Injects fuel directly on top of pistons for more efficient combustion
- Develops more horsepower per gallon of fuel
- Glow plugs (cold starting aid)
- Engine oil cooler, cools engine oil for longer engine life
- Key start and shutoff eliminates fuel shutoff knob
- Electric solenoid shuts fuel supply off immediately when key is turned off
- See-through coolant recovery tank permits operator to check coolant level without removing radiator cap

Maximize productivity with an eHydro™ transmission
The tractor is available with a three-range electronic hydrostatic (eHydro) transmission.
Sauer-Danfoss eHydro transmission is used for reliable operation. Durability features include:
John Deere’s Twin Touch foot controls offer several key advantages over competitive hydro model 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.
- 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
- 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
- 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.
- 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
- 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
- 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. Serial number break information All model year 2016 and newer tractors with serial numbers after those listed below are equipped with LoadMatch and MotionMatch features from the factory- 4044M: 1LV4044MCGG100594
- 4052M: 1LV4052MVGG100273
- 4066M: 1LV4066MHGG100181
Operator station is comfortable and convenient
Addition of optional center console toolbox
The operator’s station is designed for easy entry and exit from the tractor. Conveniently placed brake pedals, as well as repositioned operator controls, provide for a clean and flat platform design giving the operator plenty of legroom.- Hood and fenders are made from impact-resistant polymer material designed to eliminate the possibility of rusting and to resist dents that can occur with metal hoods or fenders.
- The hood is painted to an automotive-like finish, providing a high-luster appearance with excellent resilience and resistance to fading from sunlight.
- Large grab handles on each fender make getting on and off the tractor easy.
- Controls are shape and color-coded for easier identification and operation.
