Design and Fabrication of a Semi-Autonomous Tilling Machine

The world continues to experience immense technological transformations. Despite this, the field of Agriculture in many African countries has not seen much progress with regard to agricultural mechanization. Where progress has been made, many farmers have been unable to benefit due to cost constraints, among other issues. While pushing for more agricultural production through improved mechanization, it is important to factor in the cost and environmental factors. This project succeeds in developing a semi-autonomous tilling machine that performs secondary tillage and seedbed preparation activities. The machine has an average weight of 135 kg, much lighter than tractors that weigh about 2300 kg. An average tillage depth of 10.33 cm was recorded and the controller is easy to use with an average training time requirement of 3.33 minutes.
