John Deere 8370R overview
The John Deere 8370R is a high‑horsepower row‑crop flagship introduced in 2014 and built through 2019 in Waterloo, Iowa. Powered by a 9.0 L PowerTech PSS 6‑cylinder diesel, rated at 370 hp (up to 407 hp peak), it offers immense pulling force and fuel efficiency with Tier‑4 compliance via SCR emissions control. Operators appreciate its smooth and responsive infinitely variable (IVT AutoPowr) or e23 23/11 full‑powershift transmissions, delivering seamless shifting under load . The spacious CommandView III cab—with ActiveCommand steer, AutoTrac GPS, JDLink telematics, and hydraulic wet‑disc brakes—provides comfort and precision for long hours in the field. With a hefty 17 000‑gal fuel capacity, 60‑85 gpm hydraulics, and optional Independent-Link Suspension front axle, the 8370R handles heavy tillage, seeding, and transport at up to 50 km/h with ease.
**Advantages**: users and magazines report standout engine power, fuel economy, and comfort. The robust hydraulics, all‑wheel drive, and high-tech features make it versatile and efficient in demanding environments . Owners laud its build quality and reliability, outperforming competitors like Case Magnum in power and transmission quality.
**Disadvantages & common problems**: Despite strengths, several owners on AgTalk forums report increased complexity, wiring and emission‑system issues emerging around 3 500‑4 000 hours—especially with powershift variants—and expensive maintenance thereafter . Specific concerns also include intermittent SCV/hydraulic shutdowns during planting operations, loud pump noise, and issues with ILS front lifts. Recent threads highlight corner post display failures, suggesting CAN‑bus wiring fragility in the cab electronics.
**Operational costs**: MSRP for a new 8370R hovers around US \$417 000 (≈€200 000–€250 000), with used models priced €100 000–€150 000 . Fuel consumption averages around 36 l/h under load, with service intervals of 500 hr for engine oil and 2 000 hr for filters—though maintenance for emissions and electronics can escalate costs.
**Summary**: For large-scale farming requiring high power, efficiency, and operator comfort, the 8370R delivers impressively—but at a steep purchase and maintenance cost. Its complex systems demand attentive upkeep. When properly serviced and monitored, the 8370R remains a powerful, precise, and reliable workhorse, though potential buyers should budget for long-term maintenance beyond warranties.
