Mechanization and import substitution in zimbabwean farmers' equipment: A case study of the revitalization of an abandoned tractor trailer

Abstract

Abandonment of equipment on Zimbabwean A1 and A2 farms has significant costs for both farmers and the national economy, as farmers often continue using outdated or traditional farming methods. Maintenance practices, innovation, research, design, and modern machinery have evolved considerably over the past hundred years, shifting from old maintenance applications to planned maintenance strategies combined with Import Substitution Industrialization (ISI). For Zimbabwean farmers, adopting this approach is crucial, particularly for revitalizing farm implements and machinery. Currently, it is evident that many farm implements and equipment have been abandoned. These implements and equipment could be assessed and mechanically restored to their operational state. A mechanical assessment of abandoned equipment was conducted, focusing on main components such as the chassis and suspension to facilitate the revitalization process. This was followed by a product development plan outlined in the methodology. The abandoned trailer was dismantled, with selected components purchased locally, and then reassembled using mechanical methods. The mechanical activities involved included cutting with grinders, joining through arc welding, and using bolts and nuts. As a developing country striving to adopt modern technologies, Zimbabwe's application of Import Substitution Industrialization is a crucial strategy for embracing sustainable development. Farmers are advised to integrate basic welding knowledge into their farming activities and acquire essential machinery, such as CO2 welding machines and workbenches, for their mechanical workshops. Large-scale farmers in Zimbabwe typically have workshops equipped with these basic machining tools. The abandoned trailer was reconditioned to a functional state using basic machining methods and tools, as detailed in this paper.
