Maintenance, operating costs and economics
When evaluating a high‑power tractor like the T8.390, total cost of ownership (TCO) is a major consideration. Fuel efficiency, service intervals and component longevity affect profitability over the machine’s life.
Fuel consumption and operating efficiency
Large tractors can be surprisingly efficient when operated in their optimal power band. The Auto Command CVT helps maintain engine RPM close to the most economical point while adjusting ground speed for load changes, which can result in tangible fuel savings compared with older step‑gear transmissions.
- Real fuel consumption depends on task: draft work at low speeds, transport at higher speeds, and PTO‑driven operations all yield different consumption profiles.
- Precision farming integrations (e.g., variable rate application) can further reduce input costs and increase per‑acre efficiency.
Service intervals and reliability
- Routine maintenance items include engine oil changes, fuel system servicing, hydraulic oil checks and air filter replacement. Intervals vary with use but are typically aligned with industry norms for high‑power tractors.
- Designed for robust duty cycles, many owners report long service lives when following manufacturer maintenance schedules and using genuine parts.
Resale and lifecycle value
High‑spec tractors from established manufacturers tend to retain value well, particularly when equipped with modern electronics and telematics packages. Factors that preserve resale value include documented maintenance history, low hours relative to size of operation and desirable options such as precision guidance.
