Machines travelling in forest stands cause dynamic loading of soil, the size of which depends on a multitude of factors such as terrain ruggedness, machine speed, axle load and tyre inflation pressure. To decide on harvesting and transport machines suitable for specific field conditions, it is necessary to have at least some awareness about their dynamic effects on the soil, which sometimes considerably differ from static values measured on standing machines. The paper deals with the method of determining dynamic ground pressures according to the given parameters of vehicle weight and speed. At the same time, it compares dynamic pressures calculated by using this method with actually measured values.
