Wear of working tools is one of the major problems when machining soil masses. The process consists of many factors, including the item of work, the properties of the soil and the parameters of the working process. A plain carbon steel is the most common commodity currently used in metallurgical mining and the agricultural industries in India. Especially mild steel is usually used for the manufacture of agricultural equipment and critical parts in agricultural machinery industries and is therefore wearing fast under high load and abrasive conditions. Wear is the main reason for the loss of performance of the parts for agricultural machinery. It leads to the degradation of the soil working quality. This work aims to highlight the wear resistance agricultural disc of the harrows discs manufactured, consolidated and sharpened differently. The tests were conducted in the field in G.B.P.U.A&T. Pantnagar, Uttarakhand and for measurement the gravimetric wear of agricultural discs made of different materials. Experiments were conducted on the Agricultural disc in order to find out the effect of different operating time on weight reduction in field condition moisture content of about 12-14 per cent (dry basis), depth of operation 10 cm and speed of operation 4.5 km/h at working period of 100 hours. Four types of make of disc used in this study were T1(36.3), T2(38.1), T3(41.5) and T4(42.1) agricultural disc hardness respectively. The average maximum weight losses were 1004.75, 848.86, 705.74 and 549.88 g for T1(36.3), T2(38.1), T3(41.5) and T4(42.1) respectively. The effect of working time and wear loss in weight of the agricultural disc on materials T1 to T4 respectively was found to be significant at 1 per cent level of significance.
