2024 John Deere 3025E Compact Tractor

2022 John Deere 3 Series 3025E

• Standard four-wheel drive (4WD) for maximum traction

• Tightest turning radius in its horsepower class

• Hydro transmission with Twin Touch™ pedals for ease of use

Features may include:

• The 1.642-L (100.2 cu in.) displacement, liquid-cooled 3TNV88F-EPJT1 Yanmar® diesel engine provides 18. kW (24.4 hp) to the 3025E.

• 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 3032E.

• The 1.568-L (95.68 cu in.) displacement, turbocharged, liquid-cooled 3TNV86T-NJT Yanmar diesel engine provides 27.4 kW (36.7 hp) to the 3038E.

• 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 comparted to engines not using CRS technology. 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.

• 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 factors:

• 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.

• 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 the PM.
