This article deals with loading analysis of draft sensor which is used in nowadays tractor as standard. Directional sensitivity and response to the loading force of draft sensor behavior are the main goal of this work. For this purpose special measuring chain was developed. Experiment was realized with ZETOR 130 HSX which uses BOSCH draft sensors as a source for force sensing. Applied loading was measured with calibrated load cell located in measuring chain between draft sensor and ratchet mechanism. In total, three positions of lower arms were examined. Maximum loading force reached value of 30 kN. This was limited by ratchet mechanism regulations. Each configuration represents different loading conditions on draft sensor. The measured load curves were compared to each other for clarifying of draft sensor directional dependency. The obtained information’s about draft sensor are summarized in the end of the text. The results achieved from realized measurement shows force dependence on the output voltage of draft sensor.
