The effect on soil bulk density and porosity at 2 depths (0-6 and 15-21 cm) was determined for 2 soil moisture contents (17 and 23% by weight) for the number of passes over the same area and for 2 machine types (rubber-tyred skidder and crawler). Despite a three-fold difference in contact pressure, changes in soil density and porosity caused by an unloaded, rubber-tyred log skidder did not exceed those caused by a crawler.
