农业机械尽管种类繁多 ,但并非每一个作业环节都有实用的机型与其相适应。在农业生产实践中 ,笔者发现目前缺乏实用于中耕的小型高地隙动力机械。在如今应用较为普遍的动力机型中 ,铁牛 -５５拖拉机虽然有６５０ｍｍ的高地隙 ,但由于其车体重 ,对土壤的压实力太大 ,同时 ,其轮 Although a wide range of agricultural machinery, but not every operation have practical models compatible with them. In the practice of agricultural production, the author found that there is a lack of small high clearance dynamic machinery for practicing cultivation at present.
