Abstract

In order to find a generalized MATHEMATICAL MODEL for predicting the DRAFT force of an OBLIQUE BLADE SUBSOILER with a completely submerged blade, four simulated models, developed by Duriraj and Kumar (4) Perumpral et al. (14) Godwin and Spoor (6) and Mckyes and Ali (13), were compared with the results of this experiment. Field experiments were conducted to evaluate DRAFT force of the OBLIQUE BLADE SUBSOILER in the Fars Agricultural Research Center in Zaighan, with rake angle at four levels (7.5, 15, 22.5 and 30 degrees) and working depth at three levels (250, 350 and 450 mm) in a dry soil. The results showed that Duriraj and Kumar, Godwin and Spoor, Perumpral et. al. and Mckyes and Ali models, having the largest R-square and minimum standard deviation of squares, respectively, could be used reasonablely to predict the DRAFT force and were in good agreement with the experimental data.
