After 21 years of field operation, one small detail is worth noting: the span-to-span connector is still in service.
This connector uses a 7-layer NBR rubber structure, designed to provide sealing performance and flexibility between spans during repeated machine movement.
From the current operating condition, no visible cracking or water leakage is observed at the connector position.
For a center pivot, this is not the most visible component, but it plays an important role in absorbing span movement and maintaining water sealing over time.
Long-term equipment performance is often reflected in these details — material selection, processing quality, structural matching, and real field operation over many years.
Reliable irrigation is not only about the main structure.
It is also about the small components that continue to perform after years in the field.
