With the vigorous implementation of the national agricultural machinery purchase subsidy policy, the purchase enthusiasm of the majority of farmers' friends has increased. However, due to the lack of sufficient professional knowledge, they often become hesitant during the process of purchasing agricultural machinery. In particular, the purchase of large and medium-sized agricultural machinery requires a large sum of money and must not be taken lightly. Therefore, the following five points are available for reference. First, adaptability The selected model and performance must meet the agronomic requirements for the quality of the work; the mechanical dimensions and the coupling method must meet the local land and power matching requirements. Second, the production The production efficiency of the equipment refers to the technical parameters such as power, speed, productivity, and utilization. It should be based on the operating scale and production tasks of the production unit, and should consider the matching of the power tool work machinery in order to give full play to the performance of the equipment and improve the utilization rate. Third, economy Mainly refers to the cost of equipment purchase and use. When purchasing equipment, it is necessary not only to consider the purchase price of the machine, but also to consider various expenses during the period of use. If only considering the price is cheap, without considering all costs incurred after the purchase, such as fuel charges, maintenance fees, etc., it may lead to a significant increase in the use of equipment over its entire life cycle, and the result is not economical. Fourth, reliability Including non-failure, maintainability and durability, etc., require the machine to be able to operate within the specified time and under the specified conditions of use without failure and can work reliably, with a long service life. It is easy to disassemble when repairing and troubleshooting the implement. Easy to inspect, common parts and components, high degree of standardization, and good interchangeability. Fifth, security Refers to the performance of agricultural machinery for production safety and environmental protection. The safety of equipment is one of the important conditions for modern equipment selection. It is required that the implements can operate safely and that the safety of drivers can be ensured in the event of an accident. The noise of the implements and the harmful substances emitted by the environmental pollution and the harm to the human body should be within the scope of national standards.
