    摘要： A working machine includes a prime mover, a hydraulic pump to be driven by power of the prime mover and to output operation fluid, a hydraulic actuator to be operated by the operation fluid, and a control device. The control device has a revolving-speed controller to increase and decrease a revolving speed of the prime mover, a first setting portion to set a limit value of the revolving speed of the prime mover, and a revolving-speed limiter to limit the revolving speed of the prime mover set by the revolving-speed controller to the limit value set by the first setting portion.

    摘要： When maintaining a ground pivot angle of the bucket constant irrespective of any vertical pivotal movement of the boom, a ground angle maintaining controlling section stops a bucket actuator when it is detected that a vertical pivot angle of the bucket has reached an elevation restricted angle which is set smaller by a set angle than an elevation limit angle of the bucket 15 or a lowering restricted angle which is set greater by a set angle than a lowering limit angle of the bucket.
