ENGINE DETAIL
The John Deere 8345RT tractor features a robust PowerTech PSS engine with dual variable geometry turbochargers, providing significant torque and throttle response for demanding applications. With a displacement of 9.0L and rated power of 345hp, it efficiently meets Tier 4B emissions standards through selective catalyst reduction, enhancing both performance and environmental compliance. A key advantage of this design is reduced power loss under load due to optimized turbocharging, although it may demand higher maintenance on emission-related components over time.

TRANSMISSION
The John Deere 8345RT features an infinitely variable transmission (IVT) via the AutoPowr system, allowing for seamless adjustments in speed without predefined gear steps. This capability enhances operator comfort and efficiency, particularly in varying field conditions where precise control is essential for tasks like planting or tillage. However, the complexity of IVT systems may lead to higher maintenance requirements compared to traditional gear transmissions, necessitating vigilant service practices to maintain optimal performance.
