Subsoiler Attached to Medium-Size Tractor for Sugarcane plantation

Abstract

Soil compaction occur under the downward forces of heavy machine in the field. The soil can be defined as an increase in its dry density, and the closer packing of solid particles or reduction in porosity. Subsoiler which large size tractor used to loosen and break up soil but almost high price for using in the field. At present, tractors 49-50 hp are widely used in the fields but still has not proper size of subsoiler to attach with. This research was design subsoiler to connect with this size tractor. The subsoiler designed was 2 shank, 2 wing and the shank length of 1 m. At the end of the shank was designed to provide the angle with 30 degrees on a width 3.81 cm. For the field test in Khonkaen province, the soil compaction depth 35 cm., 14.53% moisture content. Subsoiler can disrupt soil compaction grown down to 41 cm depths, the capacity was 2.41 rai/hr, field efficiency 70.71%, fuel consumption 3.52 liter/rai. A subsoiler for 49-50 hp tractor was designed to be utilized conveniently. As a result, it can help solve the problem in the field by themselves.
