Motivation Agricultural mechanization was once a mainstream issue. From the 1990s onwards it received less priority, as public policy concern for equitable economic development in rural areas faded. Despite recent signs of renewed interest, questions require more systematic attention. After long period neglect, our knowledge is disarray. Purpose This paper traces evolution thinking about mechan...

A mean mechanization index of 0.59 and a total machinery energy of 477.78 MJ/ha were recorded for the direct seeding paddy cultivation in Malaysia. Highest mechanization index and machinery energy were obtained in the harvesting operation (0.99 and 336.81 MJ/ha) while the lowest values were in pesticides operations (0.19 and 3.97 MJ/ha). The benefit-cost ratios for an average farmer with and wi...

The most powerful tools for analysis of formal speci cations are general-purpose theorem provers and model checkers, but these tools provide scant methodological support. Conversely, those approaches that do provide a well-developed method generally have less powerful automation. It is natural, therefore, to try to combine the better-developed methods with the more powerful general-purpose tool...

Abstract Chinese cabbage is a major vegetable widely planted in most areas of my country. With the increase market demand and growth planting area, traditional manual harvesting can no longer meet development needs times, agricultural mechanization has become trend. In view actual production situation China, important parts harvester are designed based on TRIZ theory, working principle clarifie...
