2032R

The 1.642-L (100.2-cu in.) displacement, liquid-cooled 3TNV88C-NJT Yanmar® diesel engine provides 22.9 kW ( 30.7 hp) to the 2032R.

2038R

The 1.568-L (95.8-cu in.) displacement, turbocharged liquid-cooled 3TNV86T-NJT Yanmar diesel engine provides 27.4 kW ( 36.7 hp) to the 2038R.

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 aftertreatment 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.

DOC/DPF

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 have 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 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.

PARKED FILTER CLEANING

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.

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.

• No clutching for fast and easy direction changes
• Twin Touch™ foot pedals for quick and easy forward/reverse operation
• Transmission oil cooler cools transmission oil for longer transmission life

Safety features of the HST transmission include:

• The tractor will only start with the range lever in neutral

• If the range lever is in gear when the key is turned to the start position, the instrument panel instructs the operator to shift to neutral

• The engine will shut off if the operator leaves the seat and the power take-off (PTO) is engaged

TWIN TOUCH FOOT CONTROLS

Key John Deere advantages – John Deere’s Twin Touch foot controls offer several key advantages over competitive HST models tractors.

• Some competitive hydrostatic tractors use a treadle pedal (toe-heel) design foot control for operation of the HST

• Requires the operator to use both toe and heel to change direction, resulting in increased operator fatigue
• The Twin Touch configuration also makes it easier to inch the tractor forward or rearward (i.e., when attaching to implements)

INTEGRATED HYDROSTATIC PUMP AND MOTOR

• Sauer-Danfoss® manufacturer provides the integrated pump and motor; this assures that the components are matched to each other, providing maximum efficiency
• Provides strength and durability needed for operating such attachments as loaders and backhoes
• One reservoir (with one check-point and fill point) for the transmission, differential, and hydraulic system speeds up daily maintenance
• Mechanically actuated by Twin Touch foot pedals allow the operator to select both directions of travel and speed with the touch of a toe

CRUISE CONTROL

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.

• Maintains desired forward speed without having to touch the forward pedal
• To disengage the cruise control, either apply pressure to the brake pedal or disengage the cruise control switch

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.

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: 1.93-1.95 cm (0.76-0.77 in.)
• Outside diameter: 3.15-3.18 cm (1.24-1.25 in.)

Lower bushings

• Inside diameter: 2.24-2.26 cm (0.88 to 0.89 in.)
• Outside diameter: 3.63-3.66 cm (1.43 to 1.44 in.)
