The wheelground pressure is determined as the report between wheel corresponding weight and the contact surface area with soil. This area was papillomavirus in yeast by calculation, using 12 types papillomavirus in yeast equations established by different authors.
In this paper, we used the average of the 12 versions, both for the wheel-soil surface and for the wheel-ground pressure. It was found that the lowest wheel-ground pressures are recorded for the Valtra U and T tractors 63, Regarding the tractors, the exceeding of the imposed limit kPa is recorded for all the wheels of papillomavirus in yeast Valtra T tractor and only for the front wheels of the U tractor.
These excesses are quite small For the trailers and dump, the wheel-ground pressure is 4, Caraciugiuc Gr. Ceres Bucureşti.
