NW Washington | Roller harrows like the ones made by Parma Equipment used to be very popular in the irrigated farmland in South Idaho. I think they call them "ground hogs" locally.
Sprinkler irrigation does not need tillage like furrow or flood irrigation, so they may not need them as much nowadays.
