Agricultural machinery purchase must be the main item description

One must check the quality certification mark.
Most of the good agricultural machinery products have obtained the certificates and badges issued by the relevant technical appraisal departments of the state. Such as "agricultural machinery promotion license", "production license" and "3C (compulsory product certification) logo, etc., such products are quality assured, but pay attention to the identification of the authenticity of the badge.
Second, we must have a complete set of random documents and spare parts.
There are mainly instructions for use, three-pack certificate (warranty card), product certificate, random spare parts and tools. It is necessary to pay attention to the model and index of the instruction manual and the product number, such as the engine model and power of the tractor product assembly.
Don't forget the product certificate, which is evidence of product quality. Some are hung on the machine, some are installed in random spare parts boxes, and should be carefully checked. Check the packing list to see if the spare parts and tools are complete.
The instruction manual, the three-pack certificate and the certificate must be complete, otherwise it will affect the product use and after-sales service. These vouchers are also the main evidence and basis for handling disputes according to law.
Third, a visual inspection is required.
Look at the entire machine from the front, rear, left and right directions for distortion. Is there any rusting place, is the sheet metal piece smooth and smooth, there is no leaking paint, flow paint, castings with or without pores, sand holes, burrs, plastic parts color, wall thickness is not uniform, tires, V-belts and other rubber No aging deformation, there is no place for water leakage or oil leakage.
There must be a fixed nameplate on the machine, and see if the model number on the nameplate is the same as what you need. Some look like the outside, the name is very similar, but you can't use it if you don't pay attention to it. If there is no nameplate or site, it is basically not a product of a regular production enterprise, and the quality is difficult to guarantee.
Fourth, we must pay attention to safety protection devices.
National compulsory standards stipulate that safety and qualified agricultural machinery products must have safety protection devices. Protective covers are required for the starting jaws, fans, pulleys, power take-off shafts, exhaust pipes, chain drives and cutter shaft assemblies. The foot pedal should be a non-slip board, and a yellow or red safety warning sign should be attached where it is easy to injure. Throttle, block and other places must have obvious operational symbols.
Fifth, check the assembly quality.
Check the zeros in the farm machinery, the parts are not complete, no damage; the installation is not very good. Regular qualified product assembly marks are very clear and obvious, such as timing gear assembly marks, piston top marks, etc. should be clear and clear. Check that all the fastening screws and nuts are tightened. Never replace the split pin with a wire or nail. All rotation, transmission and operating devices are flexible and have no stagnation or looseness. For example, when purchasing a rotary tiller, it is necessary to see whether the cutter shaft is flexible, whether there is obvious axial sway, stuck and abnormal sound, and the gear is flexible, and there is no shortage of parts and no oil leakage. The specifications and model of the rotary cultivator are the same.
Sixth, we must do a good test.
Purchase tractors, agricultural transport vehicles, etc. must be tested. Look at the engine after starting, shake not shake, the sound is not normal, whether it is easy to turn off the fire, take no black smoke, gear, direction, brakes, throttle is not good; when choosing a manual sprayer (s), it is best to try the sprayer A try, such as adding water to the medicine box for spraying, see if the spray sprayed out of the nozzle is small, uniform, no dripping, the valve and the joint can not "run, run, drip, leak".
Finally, we must remind farmers that when purchasing agricultural products, in addition to the inspection described above, we should also pay attention to the following four points:
1. To buy agricultural machinery, you must go to a farm business unit with a fixed business place, certificate and photo. To shop around, don't just look at the price is cheap, you must consider the price, quality and service of the product, and you can't just listen to one side. Agricultural machinery products without production plant name, no production site, and no certificate of conformity cannot be purchased; agricultural machinery that does not adapt to local natural conditions and farming habits cannot be bought; agricultural machinery products that have been eliminated cannot be bought; agricultural machinery with unknown source cannot be bought; illegal The assembled agricultural implements cannot be bought. Also, when you buy an old farm machine, you need to ask the seller for legal documents (such as the original invoice, driving license, etc.).
When purchasing expensive agricultural machinery products, you must know the details of the products and products manufacturers. You can ask the farmers who have purchased the machines around, or consult the technical personnel of the local agricultural machinery management and promotion department. You can also watch the mechanical operations on site. situation.
2. Ask for the purchase invoice. The invoice must have a tax stamp and a financial seal, and clearly state the purchase time, product name, quantity, specifications, model, price, etc. Don't ask for invoices because you don't reimburse, don't save them. Also do not receive the signature or receipt of a personal signature.
3, carefully understand the product manual, understand product performance, maintenance, maintenance knowledge. Do not operate blindly. If you do not use it according to the instructions in the instruction manual, in addition to the quality problem, according to the relevant regulations, you will lose the right to enjoy the "three guarantees" maintenance, and have no right to return.
4. Find problems and complain in time. If the agricultural machine you bought is a fake or inferior product or has a quality problem, you can intuitively identify it, you can go directly to the relevant department to complain; if you can't identify it intuitively, you should go to the relevant department for quality inspection in time, don't miss the most dispute resolution. Good time.
