A Draft Sensing Valve (often referred to as draft control or draft sensing hydraulics) in a tractor is a hydraulic component designed to automatically manage the pulling resistance (draft) on ground-engaging implements, such as ploughs, cultivators, or subsoilers. Its primary function is to maintain a consistent working depth and prevent engine overload by adjusting the 3-point hitch height based on the soil resistance encountered.
