TRANSMISSION
The John Deere 8345R features the AutoPowr infinitely variable transmission (IVT), allowing seamless transition between speeds without interruption, enhancing operator comfort and efficiency. This IVT provides infinite forward and reverse gears, making it ideal for varied field conditions and tasks that require precise speed adjustments, such as tillage or planting. However, operators may need to adjust to the IVT's different driving dynamics compared to traditional gear transmissions, which could pose a learning curve.
