Defect	In the header lift cylinder and unloader lift cylinder of harvesting and threshing machines, due to improper machining of the port block, a component part, oil may leak from the connection between the cylinder and the joint (elbow). As a result, insufficient hydraulic pressure makes it difficult for the cylinder to rise, and continued use may lead to insufficient oil volume for machine operation, potentially causing the machine to become inoperable.
Component	Other equipment (Header lift cylinder and unloader lift cylinder)
Remedy	① For all vehicles, replace the header lift cylinder with a good part. If oil leakage occurs and oil is insufficient, replenish the oil. ② For all vehicles, replace the unloader lift cylinder with a good part. If oil leakage occurs and oil is insufficient, replenish the oil.
