Tractor manufacturers need to know how farmers use their agricultural tractors for an optimal machine design. Tractor usage is not easy to assess due to the large variability of field operations. However, modern tractors embed sensors integrated into

Tractors have become heavier and more powerful, so bigger tyres are necessary to the exert adequate traction forces and to limit the soil compaction. Nevertheless, in the last 50 years, wheel load has increased more than twice the tyre-soil contact a
