Learn these four points and you can't choose a farm machine!

It can be judged from the following four aspects:

First, the quality of agricultural machinery products are accompanied by a complete set of random documents. Mainly: 1 product manual, which should detail the structure, working principle, use and maintenance, three guarantees (warranty card) and other items of the product. 2 product certification. 3 The prominent position of the fuselage should be affixed with a diamond-shaped agricultural machinery promotion license badge. 4 There should be a nameplate on the fuselage, including the main parameters of the machine, the manufacturer's name, address, implementation standard code, production license number (in thresher, diesel, submersible pump three products). 5 When purchasing agricultural machinery products with high value or easy to accident, the dealer should also be required to present the test report of the agricultural machinery inspection department. Counterfeit agricultural machinery is generally a "three no" product, without the above documents.

Second, a detailed observation of the appearance of agricultural machinery products. Mainly from the vertical and horizontal two angles to observe the deformation of the entire machine; the appearance of the paint or paint can not be lack of paint, serious flow marks, bubbling, etc., metal materials must be coated with anti-rust paint as a primer; machine Covers and sheet metal parts should be smooth and smooth.

Third, check the machine assembly situation in detail. Check that the parts of the machine are intact and that the specifications are installed. 1 All non-adjusting screws, bolts and nuts should be tightened and locked according to the specified locking method. 2 The spring washer should be used consistently. It is strictly forbidden to replace the split pin with wire or nail. 3 Containers, pipes, joints, etc. containing fuel, lubricating oil, liquid medicine, water, etc. should be tight and free of leakage. 4 All the rotation, transmission and operation devices of the machine are flexible and have no stuck; all adjustment and lubrication parts are determined to be reliable. 5 The parts of the agricultural machinery should be inspected, mainly whether the wooden parts are cracked or deformed; whether the elasticity of the rubber parts is aging; the processing quality and surface finish of the metal parts. 6 Where the machine is likely to cause harm to the user's personal safety, safety protection devices should be provided.

Fourth, we must carry out the start-up test. Power machinery such as tractors, combine harvesters, and agricultural vehicles should be tested to see if the starting performance of the machine is good; whether the engine is running smoothly, whether the fuel is burning and whether the sound is normal; whether the direction, brakes, throttle, etc. are sensitive and reliable. High-speed rotating agricultural machinery, such as thresher, pulverizer, etc., pay special attention to the balance of the machine's drum (rotor), the machine should be stable during normal operation, no abnormal impact sound and periodic vibration, no overheating at the bearing, etc. . Machines with pressure vessels, such as motorized sprayers, should be tested to see if their pump pressure can reach the specified value, if the safety valve is functioning properly, and if there are any leaks in the piping and fittings.
