The method is developed for carrying out the experimental determination of friction coefficient of a wheeled mover with the soil surface, slipping coefficient, rolling and dragging resistance coefficients which depend on physical-mechanical properties of the soil bearing surface and bunch dragging part. Before the beginning of the experiment on a logged land, bunches of trees were prepared and weighted. The above mentioned coefficients were measured in real operating conditions and presented in the tables.

Из основных эксплуатационных и конструктивных параметров, определяющих возможность применения колесных тракторов на трелевке пачки деревьев, особо выделяются коэффициенты сцепления движителя с поверхностью грунта, буксования и сопротивления качению.
