The experiment was conducted at G.B. Pant University of Agriculture & Technology, Pantnagar. A rotavator is popularly used to reduce the amount of time and labour spent in field preparation. However, wear of rotavator blades is very high, especially in sandy soil, which significantly affects its working life. This study was ADI rotavator blades compared to indigenous and imported rotavator blades. The test result showed that average gravimetric wear rate of ADI and indigenous blades were 110.08, 129.98, 154.42 and 106.87 % of imported blade. It was also found that the average width wear rate of the ADI blades (T1) at starting, bent and leg section were 0.36mm/h, 0.25mm/h and 0.025mm/h than (T2) 0.40mm/h, 0.27mm/h and 0.031mm/h and (T3) 0.42mm/h, 0.27mm/h and 0.037mm/h while those of the indigenous (T4) and imported (T5) blade were 0.29mm/h, 0.18mm/h and 0.021mm/h than 0.26mm/h, 0.17mm/h and 0.016mm/h respectively. The wear rate of the ADI blades all treatments were significantly more than those of the indigenous and imported blades, indicating a maximum wear loss. Therefore, it was concluded that material composition of blades affects wear characteristics of both types of blades.
