The study on the dynamic position estimates of wheeled agricultural machinery was carried out in the rice transplanter through integrating the signals from DGPS、digital compass and velocity sensor.

Optimization control of maintenance and renewal of the agricultural machinery;

Adaptive weighted fusion algorithm for orientation evaluation of agricultural machinery;

Method for evaluating the risk of selecting types of agricultural machinery based on evidence theory;

Design of new trial soil slot for no-tillage farm machinery;

Therefore, has discussed the guard measure which the sliding bearing principle of work, the common breakdown type and adopts, carries on the routine maintenance in view of the breakdown reason to the sliding bearing, for impels the bearing provides the reference in farm machinery reasonable use and the maint.

The farm machinery manufacturing technique compare with general machinery manufacturing technique,has special.

Application of Agriculture Machinery Digitized Design and Manufacture Technology;

CIMS rebuild the traditional agriculture machinery;

The application present situation and prospect of CAD nology in agriculture machinery domain;

Application of discrete element method to research and design of working parts of agricultural machines;

The agricultural machine of the present age had high tech,high intelligence and complex integration and so on tendencies,these tendencies brought the major difficulty to the modern agricultural machinery failure detection and diagnosis.

The traditional ways of agricultural machine’s design leads to a long period of production design and high cost.

This is due to its unfavorable geographic conditions,backward economic situation and large rural population,rational selection of farm machinery,management and popularization of farm machinery ,to develop agricultural mechanization through agricultural industrialization,this paper has analysis adapt to farm machinery of Yunnan.

Profit Portion estimation for the mechanization in agricultural industry is useful to understand the development level,potential,trend of agricultural mechanization for government strategic decision-making.

Success and Failure for 《The Accelerate law of China Agricultural Mechanization》 are summarized, and the Question are discussed, strengthen and perfect law build fof agriculturalmechanization, the level and actual effect are enhanced by the law manage agriculturalmechanization.
