The subject of measuring was obtain the time continuance of pressure. The pressure was measured in hydraulic system of three-point hitch of ZTS-183-45-M2000 tractor, by ploughing with plow Plower. Measured continuances of pressure show good functionality and quality of hydraulics and regulation system of tractors three-point hitch. It proves that for design concept of tractor used hydraulics is appropriate. The regulation of three-point hitch hydraulic present dependable operation. In appropriate directional valve is incorporated in hydraulic circuit as by its shifting pressure peaks up to level of relief valves set value occurred. The regulation of directional valve in our opinion shows low stiffness. We recommended to carry on detail measurements of hydraulics regulation system according to favourably chosen methods
