Design steps of narrow tillage tools for draught reduction and increased soil disruption was reviewed. Narrow tillage tools are the main components of conservation tillage and soil compaction alleviation equipment. Literature regarding dynamic behaviour and step-by-step design of narrow tillage tools is scarce. A better understanding of soil dynamic behaviour and designing steps will help in the design of new tool shapes which will reduce tool draught, energy demand and increased soil disruption over a wide speed range. At the same time, narrow tools disturb less soil, ideally only the minimum necessary to establish a crop. Narrow tillage tools such as subsoilers have gain much ground in their application for alleviating soil compaction; and are attracting... |
