Traction systems for agricultural vehicles compact soil much more than the optimal density for crop yield. For this reason crop yields decrease both in the season in which compaction occurs and in subsequent years. That is why the soil compaction problem may be considered an ecological one. Among the well-known traction systems used to decrease soil compaction are; decrease of air pressure in tires, dual wheels, multi-axle wheel and crawler traction systems, improvement of tire deformation properties, etc. However, the analysis performed revealed contradictory results of using the above ways under varying operating conditions. Thus, it is not clear at what soil conditions it is appropriate to apply dual wheels, multi-axle wheel traction systems, or special appliances to increase the propulsion system's contact surface and thereby decrease its compaction. Different traction systems have varying effects on compaction for arable and sub-arable soil layers.
