For homeowners and groundskeepers seeking a reliable and versatile machine, the engine performance of the John Deere 2032R is a key factor in its appeal.
| Model | Number of cylinders | Engine displacement | Aspiration | Gross engine power* | Gross engine PS* | Power take-off (PTO) power* |
|---|---|---|---|---|---|---|
| 2032R | 3 | 1.642 L (100.2 cu in.) | Natural | 22.9 kW (30.7 hp) | 31.2 PS | 18 kW (24.2 hp) |
*Engine kW (hp), gross SAE J1995: 22.9 (30.7) at 2500 rpm, PS
Displacement, L (cu in).: 1.642 (100.2)
For comparison, the John Deere 2038R model features a slightly larger, turbocharged engine, the 3TNV86T-NJT Yanmar diesel.
| Model | Number of cylinders | Engine displacement | Aspiration | Gross engine power* | Gross engine PS* | PTO power* |
|---|---|---|---|---|---|---|
| 2038R | 3 | 1.568 L (95.8 cu in.) | Turbocharged | 27.4 kW (36.7 hp) | 37.2 PS | 22.7 kW (30.4 hp) |
*Engine kW (hp), gross SAE J1995: 27.4 (36.7) at 2500 rpm, PS
Displacement, L (cu in.): 1.568 (95.8)
Both the John Deere 2032R and 2038R benefit from Yanmar’s advanced diesel engine technology, designed for optimal fuel efficiency, enhanced control, and reduced environmental impact.
Advanced Engine Technology for Optimal Performance
The Yanmar engines in the John Deere 2032R and 2038R tractors incorporate several key technologies to maximize performance and minimize running costs.
Common Rail System (CRS)
The Common Rail System (CRS) is central to the engine’s efficiency. By injecting fuel at high pressure, the CRS atomizes the fuel into finer particles. This results in more complete combustion, leading to improved fuel economy and lower operating expenses for the John Deere 2032R owner. This optimized fuel usage is a significant advantage, especially for users with large properties or frequent tasks.
Electronic Control Unit (ECU)
The Electronic Control Unit (ECU) acts as the brain of the engine, providing precise fuel control and accuracy. Constantly monitoring engine conditions, the ECU adjusts fuel delivery in real-time to ensure peak performance and minimize emissions. This intelligent management system contributes to the reliable and consistent operation of the John Deere 2032R.
Aftertreatment System and DPF Cleaning
To reduce environmental impact, the engine is equipped with an automatic aftertreatment system. This system includes a Diesel Particulate Filter (DPF) that captures particulate matter from the exhaust.
Yanmar 3-cylinder, TNV series diesel engine
The DPF system utilizes a multi-stage cleaning process to maintain optimal performance:
- Passive Filter Cleaning: During normal operation, the engine’s heat naturally oxidizes and removes particulate matter. This occurs automatically without any operator intervention, ensuring seamless operation of the John Deere 2032R.
- Active Filter Cleaning: When engine conditions (temperature, load, speed) are not sufficient for passive cleaning, active filter cleaning is initiated. The system manages exhaust temperature and may inject a small amount of fuel into the exhaust stream to create heat and oxidize particulates. Importantly, this process also requires no operator involvement and does not interrupt tractor operation.
- Parked Filter Cleaning: In rare situations, a parked filter cleaning may be necessary. This is usually only required if automatic cleaning has been disabled or the tractor has been used under very light loads. In such cases, the operator will be prompted to park the tractor and initiate a 30-minute cleaning cycle.
This sophisticated emissions system ensures that the John Deere 2032R operates cleanly and efficiently, meeting stringent environmental standards while maintaining peak performance.
Key Features of the Yanmar TNV Series Engine
The Yanmar TNV series engine in the John Deere 2032R is packed with features designed for durability, efficiency, and ease of use:
