This is an exact-model Hongyou product page for international agricultural machinery buyers. The current factory drawing and selected configuration should be confirmed before ordering.
12JS-190 is a Hongyou heavy 12JS-series agricultural stone picker with 1,900 mm published working width, 0–300 mm digging-depth adjustment, 4.2 m³ collection box and 200 HP supporting tractor power. The product listing identifies a trailed layout with a backhoe stabilizer or digging intake, hob sorting, grid-chain conveyor, centralized collection box and hydraulic-cylinder unloading.
The function of a stone picker is to lift a controlled layer of soil, retain stones on the conveyor and return finer soil to the field. The machine is not selected by width alone. Stone size, density, soil moisture, required working depth, available tractor hydraulic connection and discharge plan all affect whether a configuration will be appropriate.
