In order to analyze the effectiveness of a particular draft control system in maintaining a constant draft loading on a tractor, a mathematical model of such a system was developed. Thus, the hitch system acts to keep a constant draft loading acting on the tractor and minimize the changes in the tractor's forward velocity that would otherwise occur. ![]() draft control, in which the hitch system attempts to com-pensate for varying soil draft conditions by automatically adjusting the depth of operation of the implement being drawn by the tractor. One purpose of most tractor three point hitch systems is to provide a mode of operation, i.e. The arti-cle describes the mathematical model and illustrates its use for improving the performance of the system investigated. YoergerĪBSTRACT IN order to analyze the effectiveness of a particular draft control system in maintaining a constant draft loading on a tractor, a mathematical model of such a system was developed.
