由于浙江省各地区自然条件和土壤性质的显著差别,为确保手扶拖拉机在沙壤土、壤土、中粘土和重粘土4类耕作阻力不同的土壤上进行作业时具有良好的作业性能和技术经济性能,中马力手扶拖拉机应具有不同的牵引力和驱动功率。对此,本文用计算分析的方法进行了阐述。 最后,本文提出了两种功率等级的中马力手扶拖拉机的总体方案。 Due to the significant difference of natural conditions and soil properties in various regions of Zhejiang Province, in order to ensure good working performance and technical and economic performance of walking tractors in soil with different farming resistance of sandy loam, loam, medium clay and heavy clay, Horsepower tractors should have different traction and drive power. In this regard, this paper uses computational analysis methods are described. Finally, this paper presents the overall plan of two horsepower walking tractors with power grade.
