Analysis of tractor maintenance costs: comparison of 10-year operating costs between electric and diesel models
1. Comparison of Basic Maintenance Projects
| Project | Diesel tractor | Electric tractor | Cost Variance |
|---|---|---|---|
| Oil/filter replacement | Annual average ¥ 2000 (every 500 hours) | need not | -100% |
| Fuel system maintenance | Annual average ¥ 1500 (for cleaning fuel injectors, etc.) | need not | -100% |
| Battery Maintenance | Replace battery (3 years/¥ 800) | Lithium battery testing (annual average ¥ 500) | +40% |
| Cooling system | Antifreeze+piping (annual average ¥ 600) | Only motor coolant (annual average ¥ 300) | -50% |
Data conclusion: The average annual basic maintenance cost for diesel engines is about ¥ 4900, while for electric motor models it is only ¥ 800, saving 84%.
2. Key component maintenance costs
Diesel engine overhaul
- 100000 hours require major repairs (cost ¥ 30000-80000)
- Common problems: cylinder wear, turbocharger malfunction
Electric drive system
- Motor lifespan ≥ 20000 hours (maintenance free)
- Battery replacement cycle: 5-8 years (cost ¥ 15000-30000)
3. Hidden Cost Analysis
Shutdown loss
- The average maintenance cycle for diesel engine failures is 3-7 days, while for electric motor types it is 1-2 days
- During the busy farming season, a one-day shutdown resulted in a loss of approximately ¥ 2000 (based on a 200 acre farm)
Energy cost
| Fuel | Annual energy consumption cost of 50 horsepower model |
|---|---|
| Diesel (¥ 8/L) | ¥ 56000 (3000L/year) |
| Electricity (¥ 0.6/kWh) | ¥ 18000 (30000 kWh/year) |
4. User decision-making suggestions
If choosing a diesel engine:
- There are no charging facilities in the work area
- Continuous high-intensity work is required (such as>10 hours per day)
If choosing an electric motor:
- The government provides subsidies for new energy (such as a 30% subsidy in some regions of China)
- Small and medium-sized farms (less than 500 acres) or intermittent use
Maintenance tips:
- Diesel engine: Regularly clean the air filter (reduce failure rate by 30%)
- Electric motor: Avoid over discharging the battery (maintain 20% -80% charge to extend lifespan)
