| dc.description.abstract | Rotavator is an efficient tillage implement used for rapid seed 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 rotavator blades which are different for different types of blades. This work was undertaken to study the material composition and wear characteristics of ADI-III Rotavator blades which were made by austempering heat treatment 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 and the study was compared to imported and indigenous rotavator blades namely, Jumbo make and Jay Bharat make. The results indicated that change in material compostion responsible for wear characteristics of blades was minimum for ADI-III rotavator blades. Iron and Carbon contents were decreased from 84.33 and 5.30 % to 72.4 and 4.20 % respectively. Minimum weight loss of 140.2 g was observed in ADI-III, followed by 159.21 g in Imported and maximum weight loss of 219.68 g was recorded in Indigenous rotavator blades after 100 hours of actual field operation. The wear rate for ADI-III blades was 1.402 g/h after 100 hours of operation which was minimum in comparison to other rotavator blades. It was found that blade section of rotavator blade was most prone to wear and reduction in thickness at blade section for ADI-III, Indegenous and Imported rotavator blade was 2.29, 3.59 and 3.29 mm respectively. | en_US |
