Rotavator is an efficient tillage implement used for rapid bed preparation and is an energy and time efficient equipment for different soils compared to all other conventional tillage implements. The primary cause that limits the persistence of rotavator is wear of its blades. This paper was undertaken to study the material composition and wear characteristics of austempered ductile iron third edition rotavator blades which were developed by austempering heat process done over cast iron. The objective was carried out by means of elemental analysis and identification of wear pattern of rotavator blades with increase in operational time. The results indicated that the change in material composition was responsible for wear of rotavator blades. Iron and carbon content decreased from 84.33 and 5.30 % to 72.4 and 4.20 % respectively. Weight loss of 140.2 g was observed in austempered ductile iron (Fe: 84.33 %, C: 5.30 %) rotavator blades after the operation period of 100 hours.
