We have not found a walk-up public scale house in Grant or Adams County with an operator page we can cite, and ScaleRegistry’s public-weighing page lists none here. We are not inventing one from industrial scale vendors, grain elevators, recyclers, landfill or transfer-station gate scales, or third-party trucker directories. Every stop below is a CAT Scale at a Love’s Travel Stop, verified on Love’s own location page.

We list only stops verified on the operator’s own location page. Both Love’s #827 and Love’s #514 list CAT Scales in their amenities and list the store as Open 24-hours — that is store hours, not a published CAT-staffing schedule. 2,000 lb floor. No corner weights. Weigh the whole rig, then drop the trailer and weigh the tow vehicle for the trailer number. Do not unload horses at a truck stop. Washington weighmaster rules differ from California — confirm ticket needs with your TO or licensing office. Use CAT’s locator for other stops.

What we still need to verify
Any dedicated public scale house in Moses Lake, Ephrata, Othello or Ritzville with an operator page that sells walk-up weighmaster certificates. CAT-scale staffing hours at both Love’s stops (only store hours are published). Love’s #413 Ellensburg (I-90 Exit 106) is a verified CAT on Love’s own page but sits farther west toward Seattle — held for a Cascades / Seattle-east cluster. Livestock policy everywhere.
