拖拉机与农具组成最佳机组是一个比较复杂的问题。一方面因为土壤种类、状态对牵引功率的传递有很大影响,另一方面由于目前在农具功率消耗方面所掌握的数据甚少。实际上经常是根据拖拉机与农具匹配不当的后果来研究最佳机组的。本文以整地作业机组为例,阐述了拖拉机发 Tractor and farm tools to form the best unit is a more complex issue. On the one hand, the soil type and state have a great influence on the transmission of traction power, and on the other hand, there is very little data available on the power consumption of agricultural implements. It is often the best to study the best unit based on the consequences of improperly matching the tractor with the implement. In this paper, as an example, the preparation of land preparation unit is described
