VALTRA 6850HI ENGINE
The Valtra 6850Hi is equipped with a SisuDiesel 4.4L 4-cylinder diesel engine, which offers a balance of power and fuel efficiency, ideal for medium to heavy-duty applications. Its 43.6-gallon (165.0L) fuel tank provides extended operational time, reducing downtime for refueling during long agricultural tasks. However, the reliance on a relatively small diesel capacity compared to larger tractors may limit continuous high-load usage without planning fuel stops.

VALTRA 6850HI TIRES
The Valtra 6850Hi with standard agricultural tires (14.9R28 front and 18.4R38 rear) provides a substantial ground contact area, enhancing traction and stability during field operations. The tire sizes are optimized for various soil types, ensuring effective power transfer and reduced soil compaction. However, users should consider potential limitations in maneuverability in tighter spaces due to the larger rear tires, particularly in row-crop scenarios.
