Disk Harrow Soil Cultivation Tillage Loamy Sand Agricultural Machinery Soil Cone Index

Abstract

A study was conducted to evaluate the performance of a disk harrow as a primary cultivation tool in loamy sand soil. Four plowing speeds viz. three different soil surfaces classified as low soil cone index, medium soil cone index, and high soil cone index were investigated. The results show that draft force tends to increase with plowing speed and that this relationship is almost linear at speeds between 1.82 and 7.59 km/h. Also, the results showed that draft force tends to increase with soil cone index and that this relationship was almost linear at soil cone index between 233 and 1592 kPa. The high value of the coefficient of determination recorded in the draft model equation indicated that the equation could enable anyone to predict the draft requirements of the disk harrow operating in loamy sand soil within the range of plowing speed and soil cone index used in the field.
