HESSTON 80-90 TIRES
The Fiat-Hesston 80-90 tractor offers versatile tire options with 2WD and 4WD configurations, allowing adaptability for various agricultural tasks. The larger 4WD front tires (13.6-24) enhance traction and stability on uneven terrain, while the potential for Ag rear tire choices (13.6-38/16.9-34) provides a balance between load capacity and maneuverability. However, the decision between 2WD and 4WD can significantly affect fuel efficiency and operational costs, as 4WD generally consumes more fuel but offers better field performance in challenging conditions.
