The W2.5K-02S-02-04-00A Rack Weld is a high-strength structural component designed for FM WORLD harvesters, ensuring stability and durability during heavy-duty agricultural operations. Manufactured with precision welding technology, this rack provides reliable support for key machine assemblies, helping improve overall performance and service life.
Built from premium-grade steel, it offers excellent resistance to wear, vibration, and harsh field conditions—making it an ideal replacement part for maintaining your harvester’s efficiency.

Installed on the threshing drum or in the feeding section of the crop, when the crop is fed into the threshing chamber: the teeth or nails on the toothed rod rub, collide, and pull against the stem/grain, thereby separating the grain from the stem. | The "dense teeth" design of the toothed rod can enhance the contact area and improve threshing efficiency, which is more effective for high-yield, thick stem or severely lodging crops. | But the gear rod should also be matched with system parameters such as concave plate screen, grass guide plate, drum speed, and feeding amount, otherwise it may cause "unclean threshing", "high loss", and "blockage" phenomena.

Product Operate Guide
Adjustment during installation:
After installation, check whether the gap between the gear rod and the concave plate screen/guide plate meets the manufacturer's requirements. Too large is prone to incomplete threshing, while too small is prone to blockage.
Suggestion for using the gear lever after wear: Changing the surface when less than half of the wear is complete can extend its service life.
Tiktok
Maintenance and upkeep:
Regularly check whether the gear rod is bent, missing teeth, or severely worn.
Check the threshing effect. If there are grains with stems, low threshing rate, and increased blockage, the toothed rod or concave plate sieve may have deviated from the specifications.
Timely replacement or repair to avoid causing greater losses
