With advancement of technology there is now a shift from usage of mechanical hydraulic hitch control systems to electro-hydraulic hitch control systems. For higher horse-power tractors there is a significance of using Lower link sensing for draft control and are mostly used now a days. The dilemma to the tractor manufacturer is which lower link to sense or averaging of the lower link sensed forces is the way out. This paper presents the significance of averaging the lower link forces since it prevents from the ambiguity to the controller. To proof this phenomenon both field test and lab test were conducted through instrumentation. In lab test a weight box testing method was used simulating an implement condition and the results were analysed and presented in this paper. This paper proofs that averaging of lower link forces is necessary for draft sensing in Electro-hydraulic hitch system.
