Abstract

Carrot is one of the widely produced and consumed root vegetables in Ethiopia. Carrot harvesting was practiced by traditional method using metal hoe, which is characterized by high man-hour requirement, drudgery and considerable losses in terms of root damage and inefficient exposure. Thus, it was important to consider a small horsepower tractor drawn carrot digger for Ethiopian smallholder farmers was designed and developed by considering soil, root and machine parameters. The machine mainly consists of main frame, shank, power transmission system, V-shaped digger blade, eccentric pin and soil separator units. Some physical and mechanical properties of the carrot roots and soils, relevant to the design of the digger were also studied. The study was focused on creating a cost-effective and locally adaptable machine suitable for small- and medium-scale farmers. Engineering design principles, including force analysis, material selection, and ergonomic considerations, guided the development process. Overall, the tractor-drawn carrot harvester provides a practical mechanization solution, offering improved productivity and reduced production costs for farmers.
