In our development tedder relatively backward, our forage harvesting mechanization started relatively late. Especially around to see parents who still use traditional harvesting forage, so with the study of small horizontal rotary rakes design. First of all I have at home and abroad Rakes development were compared, and then put forward the idea of small horizontal rotary tedder, rake and preliminary design was confirmed data parameters; proposes specific design requirements and propose the specific program, and then studied for rakes main structure and parts of the design, and finally to rake the main components were checked to ensure the reliability of the work rakes and economic effectiveness. ?? Finally, the article also rotary rakes were future prospects, we hope our country forage harvesting development hug grass machine has developed rapidly catch up with the Western European countries as soon as possible.
