1.应用前景我国种植业的田间作业需要大功率拖拉机,用以完成深耕、深松及联合作业,长期以来,这些作业主要由国产履带式拖拉机来完成。中国一拖集团公司生产的东方红系列(东方红-54、东方红-75、东方红-802、东方红-1002等)履带式拖拉机累计产量已超过100万台,为田间耕作机械化做出了很大的贡献。但是履带(金属)拖拉机存在维修费用高、对道路破坏性大、机动性差及综合利用率低等缺点,限制了它在田间作业的发展,当前许多地区和用户需要部分替代履带式拖拉机更新换代的田间动力。根据我国现有的农业生产规模、用户的经济条件和使
1. Application Prospects The field operations of crop cultivation in our country require high-power tractors to complete deep plowing, deep plowing and joint operations. For a long time, these operations are mainly carried out by domestic crawler tractors. The output of Dongfanghong series (Dongfanghong-54, Dongfanghong-75, Dongfanghong-802, Dongfanghong-1002, etc.) crawler tractors produced by China First Tractor Group Co., Ltd. has exceeded 1 million sets and has been put into field cultivation mechanization Great contribution. However, the disadvantages of tracked (metal) tractors, such as high maintenance cost, great destructiveness to the road, poor maneuverability and low comprehensive utilization rate, have limited their development in the field. Currently, many areas and users need some replacement of crawler tractors Field power. According to China’s existing scale of agricultural production, the user’s economic conditions and to make
