John Deere 8345 RT

Tractive force on tracks

The core of the John Deere 8345 RT is its 9.0L PowerTech Plus turbocharged engine, delivering 345 horsepower. Unlike wheeled counterparts, power delivery is managed through the AirCushion tracked undercarriage. This is far more than mere rubber tracks; it is a sophisticated suspension system that isolates the chassis from field undulations. In practice, this ensures a constant footprint even on uneven terrain, which is critical when pulling heavy disc harrows or wide-span planters.

Transmission and hydraulics

The IVT (Infinitely Variable Transmission) provides seamless acceleration from 0.05 to 42 km/h without any interruption in power flow. The operator simply controls speed, while the system automatically optimizes engine RPM to maximize fuel efficiency. The pressure-and-flow-compensated (PFC) closed-center hydraulic system provides a flow rate of up to 227 L/min. This allows the machine to power modern seeders that require steady hydraulic fan motor output without pressure drops during headland turns.

Engineering and operational insights

• Frame and Weight Distribution: The low center of gravity and rigid frame design allow for highly effective ballasting. Weight is distributed evenly across the soil, significantly reducing compaction in the seedbed.
• Control Systems: The CommandView II cab offers a 360-degree view, while integration with AutoTrac technology eliminates overlaps and misses, saving up to 10% in time and fuel.
• Maintenance: The engine compartment layout is designed for easy access to radiators and daily service points, minimizing downtime during peak agricultural seasons.
