In recent years,stimulated by the purchase of agricultural machinery and tools,the agricultural machinery market has rapidly expanded.Many companies have invested in agricultural machinery production.The mud and sand are all down,the good and the bad are uneven,which exposes the lack of industry entry barriers,the emergence of a large number of short-term profitable assembly companies,and the low number of companies.The level of homogeneity of vicious competition,the inability to guarantee product quality,and the lack of motivation for industry technological innovation.The following is a simple summary of the issues that should be paid attention to when purchasing agricultural machinery:

　　1.First of all,we must understand the main manufacturers of the production machinery,and choose well-known brands with relatively large scale enterprises and strong R&D capabilities,because these companies have relatively strong quality assurance conditions,relatively stable product quality,and three guarantees.More timely.In addition,before purchasing,investigate the performance,quality and after-sales service of the farmers who have used the machine,and finally determine the specific model according to your own use and bearing capacity.

　　2.Before picking up the car,check whether the machine has a quality inspection certificate,product promotion license,three guarantees maintenance certificate and other certificates,and check whether all certificates match the product name,model,and main technical parameters marked on the machine nameplate.,The factory number and the name,address,and telephone number of the manufacturer are consistent to prevent counterfeit and shoddy products from being purchased.And read the instructions carefully,and carefully check whether the on-board tools and main accessories of the machine specified in the instructions are complete,in order to prevent the seller from cutting corners and reducing the distribution of accessories,and resolutely refuse to suggest that the factory date is too long,the storage time is long or the product is repaired.

　　3.Carefully check the appearance of the machine.Generally speaking,the appearance quality of the product reflects the inherent quality of the product to a certain extent.Before purchasing the machine,pay attention to observe whether the product has any signs of bumps,damage,paint removal and refurbishment.Whether the welding seam of each welding part is flat and firm,whether there is any leakage of oil,water and gas in the sealing part,whether the gap of each part is consistent,whether there are defects such as cracks and pores in the casting.Whether each transmission part has protective measures.National laws stipulate that agricultural machinery must have protective measures.When purchasing machinery,you must choose those products that have reliable protective measures and do not remove hidden dangers and warning signs.Do not try to save yourself to bury hidden safety hazards.

　　4.A trial run is required for power machinery.Firstly,check the starting performance,start several times in a row to check the starting condition,and then perform an idling operation,and check whether the machine is running smoothly at normal working speed for more than 10 minutes and whether there is any abnormal sound.After the operation is over,check the joint surface and seal for leakage.

　　5.Check operational performance.Actually operate the machine and check whether the operation is flexible and there is no deviation.Whether the brake lights are safe and reliable.For the supporting machinery,you can manually turn the machinery to check whether the rotating parts are flexible and whether there is jamming.
