Abstract: Secondary tillage refers to tillage activities that come after primary tillage and are carried out to establish the right soil tilth for planting and seeding. Chisel plows are agricultural implements that farmers use to till the soil in preparation for planting crops. This plough can assist in breaking up ploughman and hardpan and lessen the effects of compaction. For no-till and low-till farming methods that aim to enhance erosion control and the advantages of maintaining organic matter and farming wastes on the soil surface throughout the year, a chisel plow is helpful. This study's goal was to create a tractor-drawn chisel plow for primary tillage and assess the device's effectiveness. A rectangular frame, a tyne, a chisel, a three-point hitch, and various connecting tools, including a washer, bolts, and nuts, made up the created tractor-drawn chisel plow. The depth, field capacity, field efficiency, clod mean weight diameter, bulk density, moisture content, and physical characteristics of the soil were all taken into account when evaluating the implement's performance. The field experiment was conducted at different depths of operation, 15cm. 20cm and 25cm, and tractor forward speed of 3, 5, and 7km/hr. The collected data were statistically analyzed using R software, and statistical differences in the effects of treatment means were tested at 5% levels of significance and separated using the least significant difference (LSD). From the obtained results, the draft requirement, the mean effective field capacity, field efficiency, fuel consumption, draft power, wheel slippage, and tillage performance index were 5.68 kN, 0.98 ha/hr.93.28%, 8.076l/ha, 9.38 kW, 11.33, and 2.69 at a tractor forward speed of 7 km/hr and 25 cm depth of operations. Based on the performance evaluation results, it is concluded that the developed tractor-drawn spike tooth harrow can be efficiently, effectively, and economically used by the end users.
