A pivot applies water on the assumption that every nozzle delivers its design rate. Nozzles wear and enlarge gradually, so application becomes uneven across the field while total flow looks normal at the pump. The result is over-watered and under-watered arcs within the same circle — visible in the crop weeks later, by which point the yield effect is already set.
The steps ChatterFix schedules for this PM. Every step is a checkable item on the work order — a technician can speak their way through it without touching a keyboard.

Yield variation across a field gets attributed to soil type rather than to the irrigation system, so the same pattern repeats every season. Meanwhile drive gearboxes run low on oil and fail, usually leaving the pivot stalled — which over-waters one arc severely and leaves the rest of the circle dry, and can bog the tower badly enough to need recovery equipment.
Annually before the irrigation season, with run-hours leading in a long season. The pivot's own wheel tracks are a free diagnostic worth walking: deep ruts in one arc and dry tracks in another indicate an application problem before the crop shows it.
