Journal Article 2020 02 23 Most of the agricultural costs during tillage are related to providing the necessary traction for tillage. In this study, the power consumption during the speed levels, depth of work and overlap of a tillage tine was investigated. The experiment was performed in a soil bin at three speed levels of 0.5, 1.2 and 2 m / s for three depth levels of 10, 20 and 30 cm with width interval of 0, 10 and 20 cm of tillage tine. Statistical analysis of the data showed that the effect of speed on draft force at two levels of 20 and 30 cm depth at 5% level was significant and at 10 cm depth was not significant. Also, the effect of work depth at 5% on draft force at all levels of overlap was significant. Conical index changes at depths less than 10 cm are negligible for different levels. The effect of depth on draft force was observed in exponential form. Also, the reduction in power consumption in the overlap has been observed more.
