The object of the executed measurements which were carried out was to obtain time courses for the forces and pressures inherent in a hydraulic system for the three-point hitch of a tractor during the process of ploughing with a carrier-mounted plough and also with a semi-mounted plough. It was necessary to obtain experimental data on the basis of which it was then possible to consider and analyse the issue of dynamic loading for the three-point hitch of a tractor during basic agricultural operations. The selected operation was ploughing in random working conditions using, in turn, a carrier-mounted plough and a semi-mounted plough. The aim was to use the results obtained to simulate the loading and full usage of the three-point hitch (TPH) under laboratory condition by means of hydrostatic simulator.
