Abstract

 Results of investigations on the effect of multiple passages of tractors of various powers
(small-medium-large) on soil compaction within the track and the side zone are presented. Changes
in specific pressures as a result of variable support area of considered tractor wheels and their sidecompacting
action are also presented. There was found statistical significance of the effect of wheel
pressures, depth of soil layer and its distance from the track on soil compaction. The investigations
were carried out on clayish sand with the use of 3 tractors. Basing on the obtained results a set of
empirical equations was developed.

Keywords

tractor, tires, contact surface, specific pressures
