Why CalMill

CalMill's fleet of service trucks parked at the Turlock yard at dusk

When you call us, a person in Turlock picks up — not a national answering service that opens a ticket and calls you back tomorrow. Our technicians are dispatched from the same yard that stocks the load cells, indicators, and hardware they'll need, so most breakdowns get fixed on the first visit instead of the third.

We've been serving Central Valley agriculture since 1952, which means 74 years of working on the equipment that's actually installed here — across more than twenty manufacturers, from modern Rice Lake digital indicators to mechanical decks older than most of our trucks. One company covers repair, certification, installation, and the maintenance schedule in between.

“Get your Fischbein sewing machines and parts. Thread and tape for your machines. Machine diagnosis and repair. Prints and conveyor repair. Mill equipment like elevators and scales. Check them out for more options.”

— Donald Ebersole

“Cal Mill is exactly what you want in a local equipment company — experienced, reliable, and easy to work with. Happy to recommend them to anyone in the ag or industrial space.”

— David Messore
Field Notes

Common Questions

How fast can a technician get on site?

Most Central Valley calls get a tech dispatched within 2 hours. Emergency line is answered 24/7 — nights, weekends, harvest season.

How often does a truck scale need NTEP certification in California?

State law requires annual certification for scales used in commercial trade. We handle the test-weight calibration and county-sealed paperwork in one visit.

Do you service scales you didn't sell or install?

Yes. We carry parts and service experience across 20+ manufacturers — Rice Lake, GSI, and mechanical decks older than our trucks. One call covers it regardless of who installed it.

What does emergency repair cost?

Flat-rate call-out, quoted before a technician leaves the yard. No surprise trip charge.

Do you work on mechanical (non-digital) scales?

Yes — legacy beam and lever-arm decks alongside modern digital indicators.

Is my location covered if it's not on your service area list?

Call dispatch. Listed cities are our standard radius; we travel farther for scheduled installs and larger accounts.
