Aiming at the problems such as the low drying speed, baling difficulties of scatter hay and grass-roots rotten, a new type of finger-wheel rake was developed to meet with the market demands and meet with the demands of the forage harvest in our country.It can rake and ted the alfalfa and rice or wheat straw.The overall structure and working principle were described briefly.The major working components such as the structure parameters of the adjustable rotation frame, the extending-retracting mechanism of finger wheel and the spring tooth were designed.And finite element analysis on spring tooth and the kinematics simulation on the finger-wheel was carried out.Through the analysis of performance test results and the technical index of the prototype,it was optimized.The test results showed that all technical indexes of the machine meet the design requirements.It is easy to operate and can be used reliability.While operating, it had good ra-king effect and high working productivity.The machine can satisfy with the harvesting requirements of forage grass.
