Harvester

The invention discloses a harvester comprising an operation linkage mechanism that transmits a swinging operation of an operation lever (13) to a steering drive part and a lifting/lowering drive part.The operation linkage mechanism includes: a steering unit that links the operation lever (13) and the steering drive part; and a lifting/lowering unit that links the operation lever (13) and the lifting/lowering drive part. Each unit includes an output operating body (71) that transmits the swinging movement of the operation lever (13) to the steering drive part or the lifting/lowering drive part. Within a preset movable range of the steering drive part or the lifting/lowering drive part, the output operating body (71) moves integrally with the operation lever (13) by following the swinging movement thereof. After the steering drive part or the lifting/lowering drive part has reached a movement limit of the movable range, if the operation lever (13) is operated in a direction that moves the steering drive part or
