We Know Pivots Because We Work on Them Every Week
We’ve gotten calls from farms on Shoshone Road South, on the north side of the Snake River Canyon, and across the flat ground east of Twin Falls. A pivot down at the start of an irrigation set is a crop loss event — not a “schedule a convenient time” situation. We dispatch pivot emergency calls immediately, any time of day or night, any day of the week.
We stock common Zimmatic and Valley pivot parts in our service trucks because we make this call regularly. Contactors, fuse blocks, overload relays — we don’t make a two-trip job out of a one-trip fix.

Why Won’t My Center Pivot Start? Common Electrical Causes
Before you call us, check these first — it may save you a service call:
Blown Control Panel Fuses
Check the fuse block in the control panel. Main fuses and sub-fuses blow from power surges, lightning, and overloads. Replace like-for-like — never upsize a fuse.
Tripped Motor Overload
Overload relays trip on high motor current — often from a hard start in cold weather or a stiff pivot span. Reset and try again. If it trips immediately, call us — there’s a load issue.
Failed Contactor
The main contactor is the most common failure point after fuses. If you hear a click but the motor doesn’t start, the contactor may have failed. We carry replacements for common pivot brands.
Ground Fault on Spans
Ground faults on the pivot spans — from wire chafing, connector corrosion, or physical damage — cause the system to trip at the panel. Requires tracing with a megger. Call us for this one.

Frequently Asked Questions — Center Pivot Irrigation Electrical
How quickly do you respond to a center pivot emergency in Twin Falls County?
Agricultural emergency calls — including pivot down calls — are dispatched immediately, any time of day or night. We aim to have a truck en route within the hour for Twin Falls County pivot calls. Call (208) 719-5016 and tell us it’s a pivot emergency. We carry common Zimmatic and Valley parts in our trucks so we don’t make two trips.
What size electrical service does a center pivot need?
A typical quarter-section pivot with a 50–75 HP motor requires 3-phase power — usually 100–200A at 480V on a dedicated service. Half-section pivots with larger motors (100–125 HP) may need 200–400A. We do a load calculation during the estimate based on your motor nameplate data and any shared loads on the service.
Can you install electrical for a new center pivot on newly developed farm ground?
Yes — including the underground service run from your main farm panel to the pivot point, the field junction box, and all above-ground wiring to the control panel. We coordinate the service entrance with Idaho Power or MVEC and pull all required permits. We’ve done full pivot installations on newly developed quarter sections across Twin Falls County.
Do you work with both Zimmatic and Valley pivot brands?
Yes. We work on Zimmatic, Valley, Reinke, T-L, and other pivot brands. We’re most familiar with Zimmatic and Valley — the most common brands in Twin Falls County — and stock parts for those systems in our service trucks. For Reinke and T-L systems, we can source parts quickly through our supplier network.
