Design and development of rotavator cutting tools using advanced mechanization technology for farm fields: A research review

Abstract

The escalating cost of agricultural land preparation due to rising fossil fuel prices necessitates the adoption of efficient and cost-effective tillage methods. Rotary tillers (rotavators) are recognized as suitable machinery for seedbed preparation, with their blades being critical components directly interacting with the soil. These blades face significant challenges due to impact and friction, leading to wear and reduced service life. This research review synthesizes existing studies on the design and development of rotavator blades, emphasizing the application of advanced mechanization technologies such as Computer-Aided Design (CAD) and Finite Element Analysis (FEA). The review explores various approaches to enhance blade lifespan and performance, including material selection (High Carbon Steel, EN Steels, Boron Steel, Chromium Steels), geometric optimization (radius of curvatures), and analysis techniques (static structural and fatigue analysis). Furthermore, it considers the practical implications of blade design on weed removal efficiency and overall land preparation effectiveness. This review aims to provide a comprehensive understanding of the current advancements and future directions in designing robust and efficient rotavator cutting tools for improved farm field preparation.
