Introduction and Evaluation of Three Types of Fine Grain Products and Their Harvesters

Fine grain products are harvested in two manual and mechanized forms. Nowadays, common combine harvesters are used, but fine grain products such as Rapeseed, Sesame and Sorghum cannot be harvested with conventional heads of combine harvesters due to the excessive grain loss in the head of the combine. Therefore, the necessity of design and fabricating machines and heads of combine harvesters became the center of attention to researchers because of the nutritional and medicinal benefits of fine-grain products. This research delves into an overview of the special headers and machines for harvesting three type of fine grain products with high loss and an evaluation of each of these harvesters.
