Abstract

India is an agrarian country and about 75 to 80 % people are farmers, their main occupation is farming. Also crop production is very important part of any economy. Without crop production nothing is possible. The crop production requires some kind of machining work to reduce the human effort. In this modern era many agricultural implements are available for crop production, which are highly efficient compared to conventional equipments. Various agricultural machining equipments are used for crop production such as rotavator, shovels, cultivator, plough, tillage tools, disk harrow etc. These equipments have direct interaction with the soil. Generally farmers used disk harrow agricultural implement for crop production tillage work. They faced a general problem of circumference erosion of disk harrow. This erosion occur main due to the size of soil particles. This erosion problem is a general problem faced by every farmer. It can be overcome by using some kind of engineering modifications like design and material modifications in disk harrow. In this research paper two disk harrow designs are proposed for life analysis and improvement. These designs are based on the existing model of disk harrow. The designs are modified on the basis of erosion parameters, so that erosion occurs less as possible. The currently used material is structural steel and equivalent materials are stainless steel and steel EN45. These materials are equivalent in mechanical properties and cost.
