Compact Utility Tractor
The bold styling of the 4R Tractors provides an attractive and functional appearance similar to that of the larger agricultural tractors. Benefits of this styling include:
The result gives the tractor a distinctive appearance and feel.
NOTE: If the tractor is equipped with an optional field-installed vertical exhaust, the exhaust pipe must be removed before opening and closing the hood of the tractor.
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.
Key features of the operator's station include:
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.
The engine meets all current emission requirements for Stage IIIB (IT4) (4049R) and Stage IV (FT4) (4066R) emission standards.

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:
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
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.
Key features of the engine are:
Yanmar is a trademark of Yanmar Company Limited.
The tractor is available with a three-range electronic hydrostatic (eHydro) transmission.
Sauer-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:
Sauer-Danfoss eHydro transmission is used for reliable operation. Durability features include:
Safety features of the eHydro transmission include:
John Deere's Twin Touch foot controls offer several key advantages over competitive hydro model tractors.
The eHydro convenience controls have been integrated into a single module. Combining features such as SpeedMatch™ LoadMatch™, MotionMatch™ eThrottle™ (eThrottle not available on the 4049R) 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.
Press button to active/deactivate eThrottle. When eThrottle is activated, depression of the travel pedal increases engine RPM and tractor speed.
|Press button to active/deactivate LoadMatch. When LoadMatch is activated, engine will not stall during heavy load applications.|
|Press button to activate/deactivate SpeedMatch. When SpeedMatch is activated, operator is able to set the desired maximum travel speed.|
|Press button to activate/deactivate cruise control. When cruise control is activated, operator is able to set cruise speed.|
|Press button to set cruise speed, or to decrease cruise/set max speed.|
|Press button to resume set cruise speed, or to increase cruise/set max speed.|
|MotionMatch - longer accelerate and decelerate distances.|
|MotionMatch - shorter accelerate and decelerate distances.|
Press a button to activate/deactivate eThrottle™. When eThrottle is activated, depression of travel pedal increases engine rpm and tractor speed simultaneously. This provides the operator with comfort and convenience as well as fuel economy.
An automotive-style cruise control is standard equipment on the 4R Series Tractors. Cruise control is electronically engaged and disengaged and is located on the right-hand operator console.
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.

John Deere ComfortGard cab tractors are the most comfortable, quiet, and easy-to-use cab tractors available. This premium solution was developed using extensive customer research and validation, tools, and some of the most advanced design techniques available.
The following John Deere ComfortGard cab tractor models are available:
Cab tractors are designed for those who demand superior performance:
Whether using a loader to move dirt or remove snow or doing a variety of other tasks like mowing, front implement work (such as snow removal), tilling, rotary cutting, or light hay work, the cab tractors have the versatility and muscle to get the job done, all while protecting the operator from the elements.
Operators are sure to appreciate what this cab has to offer – beginning with an isolated cab. These cabs are designed with robust mounting points integrated into the rollover protective structure (ROPS) with a unique offset mounting design that provides an ultra-quiet ride.
A 4-post ROPS design, carefully laid-out interior, and fuel tank located under the left rear side of the operator's platform provide a full 360 degrees of visibility:
Operators are well-protected from the elements with a high-performance climate-control system providing heating and air conditioning.
An air-ride seat is standard on the 4R Cab Tractor. This seat is designed to provide an air cushion for vertical-seat travel which provides maximum operator comfort in any terrain.
NOTE: The deluxe two-piece seat top may be ordered through Parts.
Key benefits include:
The base lighting package for cab tractors includes:
Optional lighting includes:
Several features are integrated into the design of the cab that deliver superior operator comfort and visibility:
Safety is designed into all 4M and 4R Series Tractors.
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:
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.
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.
All items in the daily service schedule can be performed without the use of tools:
NOTE: Always refer to the operator’s manual for complete maintenance and service recommendations.
