Customer Custom Matching & OEM Technical Agricultural Machinery Parts Solution Cases
ChangJia's technical team delivers customized OEM parts matching & machining solutions for John Deere, Case IH, and mainstream farm equipment. As a professional agricultural machinery parts manufacturer, combining our complete OE database, independent R&D capability, and flexible custom production to solve unique equipment adaptation problems for global agricultural distributors. Below are typical customized cases covering harvester crushing systems, cutter head components, and tractor PTO gear modification.
The Dura-DrumTM large-diameter cutter head enables faster material flow, lower power consumption and higher efficiency. The new cutter head brake can stop in just 7 seconds. The blades can be installed separately, and the installation time is less than one minute. Reversing the grinding process can keep the blades sharp for a longer time, reducing the frequency of blade replacement and saving you time and cost. The new intelligent alignment system can quickly align the blades in just 45 seconds, increasing the effective operation time, saving fuel
The grain crusher with ultra-durable technology has a longer service life. By increasing the diameter of the crushing rollers and enabling electric adjustment of the roller gap, the operation becomes more convenient. For John Deere models 8400 and 8500, 40% higher differential ratio is newly available as an option, resulting in a 7% increase in grain crushing rate and providing you with higher-quality feed.
The John Deere 1354 tractor originally features a dual-speed PTO (power take-off) configuration, with a hollow shaft carrying two gears—540 rpm and 1000 rpm. Since the customer’s two commonly used implements both operate at a medium speed, we replaced the original dual-speed gears with a single-speed gear to match them. Once the single-speed gear is installed in the PTO position, the speed change is completed, ensuring convenient operation for the customer.
