With the vigorous implementation of national policies, the boom in the purchase of farm machinery has continued. The majority of peasant friends actively buy their own farm machinery. The purchase of agricultural machinery requires a lot of savings, so you must choose carefully when you purchase it. The following points are tips when buying a farm machine:
First, check the data
Check carefully to see if you have a complete random file. When purchasing high value or importing agricultural machinery, the distributor shall also be required to present the inspection report of the inspection department of the agricultural machinery, import customs clearance procedures and product quality inspection forms.
Second, observe the appearance
Observe the appearance of agricultural machinery products carefully. Mainly from the vertical and horizontal angles to observe the entire machine with or without deformation, the appearance of the entire machine is not missing paint, severe scratches, blisters and other phenomena. Metal materials must be coated with anti-rust paint as primer, machine cover parts, sheet metal parts should be smooth and so on.
Third, check the assembly
Check the machine assembly in detail. Check whether the parts and components of the agricultural machinery are intact and error-free and whether the installation specifications are correct. All the rotating, transmission and operating devices of the machine operate flexibly without any stagnation. Have a reliable safety protection device. Any place on the machinery that may cause harm to the user's personal safety should be equipped with safety protection devices. There must be a permanent warning sign at the site of an accident.
Fourth, start the test
Be sure to conduct a startup test when purchasing machinery. Understand whether the performance is good, whether the engine works smoothly when the engine is working, whether the combustion condition and the engine sound are normal, and whether the direction, brake, throttle, etc. are sensitive and reliable. The high-speed operation of agricultural machinery (threshing machine, grinder) should pay special attention to the balance of the machine drum. A machine with a pressure vessel (motorised sprayer, etc.) should be tested to see if its liquid pump pressure has reached a specified value, if the safety valve is functioning, and if there is a leak in the piping and fittings.
