Abstract: The evaluation of the draft which the sol opposes, with its physical and mechanicals properties, to the advance of a body of share plough is the several research task object whose results lead to the presentation of several mathematical models. These models often introduce the properties of the soil, particularly its specific resistance and its density. The analysis of these models shows that the geometrical characteristics of active surfaces are however not taken into account. The objective of this study is the choice of the model to be used for an evaluation of the draft has an importance when the precision of calculation is required. For that 2 models were selected. The first is that proposed by Gorjatchkin, the second one is proposed by Gee Clough. The relations between measured and calculated effort are: FtEnpma = 5.05 + 1.72. FtGee -0.72. FtGor and FtSacra = -18.79 + 0.24.FtGee + 1.46. FtGor.
