Simulation of Narrow Blade Performance in Different Soils
ABSTRACT FOUR mathematical models that predict draft force and disturbed soil area by a narrow blade were compared through a computer simulation and experimental measurements taken in two soil textures at different field soil moisture conditions. The models studied were: (a) Hettiaratchi and Reece (1967); (b) Godwin and Spoor (1977); (c) McKyes and Ali (1977); (d) Grisso et al. (1980). Computer simulation was then utilized to predict the effects of different parameters on the blade performance using the four models.
