Seeder purchase common sense
Suggestions on how to purchase a planter are as follows: First, farmers' friends should consider the power (or horsepower) of their own tractor. If it is 55 horsepower, your choice of wheat seeder should be 11 to 16 lines; corn planter should be 4 to 6 lines; miscellaneous grain seeder should be 4 to 11 lines. Secondly, to purchase products produced by the state's regular enterprises, it is best to use brand-name products, so as to ensure the quality of product manufacturing and prevent counterfeit products. In addition, it should also be purchased by merchants with a certain sales history and scale to obtain the guarantee of corporate reputation and service capabilities. Third, check with the seller in person. The first is to check whether the purchased products have product certification, operating instructions, "three packs of vouchers" and related technical documents; in particular, pay attention to the "three guarantees" period of the whole machine, and the effective period of the main part three guarantees. The second is to check the structure of the row and fertilizer feeders. Take a look at whether it is suitable for the user's seed and fertilizer situation. Some products are seeded and the fertilizer is made of recycled plastic. The product is not wearable and it is damaged in a short time. The third is to check the drill opener form in detail. Suitable openers should be made of a harder, rigid material (should be equivalent to 65Mn). Fourth, test run. It is necessary to pay attention to the performance of the machine and observe the appearance quality. Fourth, ask the seller for a formal purchase invoice. Because the invoice is one of the important vouchers that require the "Three Guarantees" service. Finally, after purchasing the machine, farmers' friends must read the instructions carefully and follow the adjustments, maintenance, etc. required in the instruction manual to do all the preparatory work before sowing.
ULITE Welding Machine has industrial quality and DIY quality. Involving industrial field and family life. We use IGBT and MOSFET inverter technique to product.
Advantage:
