Parked at the farm, ready for loading at the local co-op or heading down the highway, these SceneMaster Fertilizer Nurse Trailers are a must-have detail for rural HO scenes! Most often used to move liquid fertilizer from distributors to farms, the prototypes are also used to haul drinking water for livestock in some areas. The kit includes parts to build four complete trailers, each molded in two colors, that match the trailers included in the Cornerstone Fertilizer Distributor kit (933-4128) sold separately.
