To obtain the total performance of a tillage implement, besides measuring draft and energy requirement, it is important to evaluate the abrasive wear of the tillage tools. Abrasive wear is due to the interaction between soil and tool surfaces. Given to the importance of these two topics, many studies have been conducted by researchers on tillage tools wear as well as their draft requirements in situ (field test) and in controlled environment (soil bin). In the field tests, despite of the actual test conditions and more realistic results, controlling most of the factors affecting the performance of the tillage tools is not possible, and is expensive and time consummating. Most of the studies on the wear of tillage tools have been conducted in laboratory by abrasive wear devices using small dimension of the material from which the tillage tool is made. In this study, after troubleshooting and equipping a rotary soil bin in the Biosystems Engineering workshop of the Isfahan University of Technology, the wear resistance and power requirement of three tillage tines were investigated. During the tests, the oil temperature in the hydraulic power transmission system of the soil bin was raised to more than 65°C, therefore, an oil cooling system was considered for the hydraulic power system. Raising the oil temperature to above 50°C, which is the maximum permissible temperature for most hydraulic systems, causing oxidation, decreasing viscosity and oil film thickness, and eventually lead to damage to the seals and will reduce the life of moving parts. By designing and selecting a suitable air cooling system, the increase in oil temperature was solved. In order to push down and level the soil surface behind the working tillage tool, a smooth roller for the soil bin was designed and constructed. According to the calculation, the weight requirement for compressing the soil to a depth of 200 mm was about 154 kg. Bulk densities (BD) measurements showed that the roller was able to increase BD a value of 1.75 g/cm 3 . In order to moisturize to specific water content, a water sprayer was designed and constructed. To have uniform water spraying with non-splash, a disc nozzle of a microner sprayer was used. After the design of moisturizer system, the water contents in the depths of 0-10 and 10-20 cm were measured and the performance of the system was good. In order to measure the draft force, a tension-compression S-shaped loadcell, with a maximum capacity of 5 kN, was installed at the junction of the shank of tillage tool and the frame of the soil bin carrier. After equipping the soil bin, the abrasive characteristics of a narrow chisel blade made from CK45 steel with a working width of 30 mm and working at constant depth of 200 mm and at two water contents of 0.5 PL and 0.9 PL and at the speed of 5 km/h with three replications were evaluated. The blade wear was measured by weighing method using a digital scale with a precision of 0.001. Results showed when water content was increased, wear rate was reduced. The decrease in wear rate can be attributed to increasing the soil plasticity and soil adhesion to the blade surface and as a result decreasing metal friction. The loadcell calibration was obtained using a universal tension and compression machine. Draft, specific draft and drawbar power of two narrow chisels with widths of 30 and 50 mm, and a sweep with a width 180 mm at working depth of 200 mm, at two water contents of 0.9 PL and 0.5 PL and two speeds of 3 and 5 km/h using a completely randomized factorial experiment with three replications was determined. Analysis of variance results showed that forward speed and soil water content had significant effects on the performance of tillage blades. Mean comparison showed that with increasing the forward speed and soil water content, draft, specific draft, and drawbar power for each of the three blades increased (0.05 LSD). This could be due to an increase in impact force from the blades and soil adhesive forces between soil and the blade, respectively. The tine type also had a significant effect on drawbar power. Maximum mean value of the drawbar power was related to sweep blade and water content of 0.9 PL and speed of 5 km/h treatment with value of 4.16 kW and the minimum mean value of the drawbar power was related to narrow chisel blade and water content of 0.5 PL and speed of 3 km/h with value of 0.95 kW.
