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 a 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 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.
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 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.
If conditions (temperature, load, or speed) for passive filter cleaning cannot be achieved, then particulate matter 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 particulate matter.
It is important to note that at no time is fuel in the DOC/DPF ignited, and there is no interruption to tractor operation.
Like passive filter cleaning, active filter cleaning requires no operator involvement, and there is no interruption to tractor operation.
In some instances where passive and active filter cleaning have not fully cleaned the particulate matter 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.
The emissions system on this engine 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.

Yanmar TNV Series engine offers these features:
The 2032R and 2038R Tractors are equipped with a two-range hydrostatic transmission (HST) incorporated in a die-cast aluminum transmission case. Fluid under pressure transmits engine power to the drive wheels via a closed-loop pump and motor arrangement. Infinite ground speeds allow the operator to match the speed of the tractor to the job.
Safety features of the HST transmission include:
Key John Deere advantages – John Deere’s Twin Touch foot controls offer several key advantages over competitive HST models tractors.
An electronic cruise control is standard equipment on the 2032R and 2038R Tractors. Cruise control is electronically engaged and disengaged using a toggle switch located on the right-hand console.
Sauer-Danfoss is a trademark of Sauer-Danfoss Incorporated.
The operator station has been designed to allow for greater operator comfort and increased visibility. The ergonomic layout and convenient color coded controls allow for easy identification and operation. The design of the operator station allows operators to sit “in” as opposed to “on” which provides comfort and increased stability.
Below are other key features of the 2032R and 2038R Tractor operator’s station:
The thick, soft padding on this seat provides a smooth and comfortable ride. A high, scalloped back makes it easier for the operator to turn to view rear implements.
Key features of the operator’s station include:
One of the greatest operator 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 American Society of Agricultural and Biological Engineers (ASABE) Category 1 Standard S278.6 for quick-attach hitches.
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).
The 2032R and 2038R tractors feature a newly designed, CommandCut™ mower deck lift system, which allows quick and accurate adjustments of the mower deck with the turn of a dial and the bump of a lever. Control callouts make operation simple and repeatable. The height of cut setting dial and raise/lower lever are conveniently located on the right-hand console and easily accessible by the operator. Some of the key benefits of this system are:
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.
The 2032R and 2038R Tractors come equipped with the eThrottle feature. This feature is designed to make the tractor quieter and use less fuel. With eThrottle engaged, the engine rpm and transmission speed will increase as the Twin Touch™ pedals are depressed. This feature can be beneficial for use in many different applications, especially for front loader work and when transporting on roads or in parking lots. To enable the system, producers press the switch located on the right side of the front console. Once the system is enabled, engine speed will then increase or decrease in unison as the Twin Touch transmission pedals are depressed. For loader work, producers will get maximum benefit from the system by increasing engine rpm with the hand throttle to at least 50 percent. Once the hand throttle is set, eThrottle will help provide the feeling of a power boost when the producer is filling the bucket with material from a pile. The harder the Twin Touch pedal is pressed, the more engine speed available. In this scenario, as the producer presses the pedal, the engine will operate between 50 percent throttle and 100 percent throttle. It will not go below 50 percent until the hand throttle is lowered back down. For transport applications, it is recommended to engage eThrottle but leave the hand throttle set to low idle so that eThrottle can control the entire range of engine speed from 0 percent up to 100 percent. In power take-off (PTO) applications such as mowing or snow blowing, eThrottle is not recommended because PTO implements usually require a constant speed in order to properly function.
