| Abstract: | Mathematic model was used to identify the interrelationships among various factors of the great power tractor and secondary tillage unit,and the formulas of tractive efficiency,working efficiency and fuel economy were deduced.The matched conditions of the tractor and secondary tillage unit for ideal tractive efficiency,ideal working efficiency and optimum fuel economy were illustrated as follows based on actual calculation and optimization: the working speed of the unit should be 6.3208 km/h,it should carry 24 disc harrows,11 deep-shovels and 100 spring tine harrows. |
