1及时淘汰旧机型农村大量使用的小型拖拉机,单位功率油耗比大型拖拉机高出20%,造成高耗油;拥有的大中型拖拉机中约有30%左右是老旧机型。这些老旧机型能耗高、效率低,部分拖拉机已超过或接近报废更新年限,其作业质量恶化,功率严重下降,存在严重的安全隐患,油耗也急剧上升,通过修理也无法达到良好的技术状态,在农业生产中造成了很大的燃油浪 1 in time to eliminate the old models Large-scale use of small tractors in rural areas, unit power consumption than large tractors 20% higher, resulting in high fuel consumption; owned medium and large tractors in about 30% of the old models. These old models are characterized by high energy consumption and low efficiency. Some tractors have exceeded or approached the renewal deadline. The quality of their work is deteriorating and the power is seriously deteriorated. There is a serious safety risk and the fuel consumption also rises rapidly. Good technology can not be obtained through repairs State, caused a great fuel wave in agricultural production
