DESIGN OPTIMISATION OF ROTARY TILLER BLADE TOWARDS SERVICE LIFE ENHANCEMENT

A rotary tiller or rotavator is active tillage equipment used to prepare farmland for sowing seeds, weeding, mixing manure and fertiliser into the soil, crushing soil blocks, etc. Compared with conventional farming, advantages of this are rapid seedbed preparation reduced draught. Nowadays, utilisation rate tillers has increased. However, blades key component that engages in tiller. These interact differently from ordinary ploughs bear impact loads high frictional forces, which eventually generate unbalanced uneven forces on entire As a result, blade faces significant wear. Therefore, it necessary optimise design minimise wear enhance service life. In research work, optimisation was carried out towards improving
