Addressing the issue of starter rods being susceptible to mud, water, and corrosion during agricultural machinery operations, a domestic parts manufacturer has launched a specialized starter rod for agricultural machinery. This starter rod features a double anti-rust treatment of galvanization and powder coating, achieving an IP67 rust resistance standard. It can be used long-term in muddy and wet field environments, offering three times the rust resistance of ordinary starter rods. Simultaneously, the starter rod is thickened to 12mm, enhancing its impact resistance and making it compatible with various agricultural machinery such as tractors and harvesters. The company has also adjusted the lever ratio of the starter rod according to the starting force requirements of different agricultural machinery, reducing operational intensity and making it easier for farmers to use. Currently, this specialized starter rod has been widely adopted in major agricultural provinces such as Shandong and Henan, with monthly sales exceeding 8,000 units. According to user feedback, using this starter rod has reduced the frequency of starting failures in agricultural machinery by 60% and reduced maintenance costs by 40%.
