御装置。 In a front loader control device in which a boom 10 is raised and lowered by a boom cylinder 11, and a bucket 13 is scooped and dumped by a bucket cylinder 14, it is detected that a load exceeding a predetermined value is applied to the bucket 13. A pressure switch 71 is provided to allow the bucket 13 to scoop and the boom 10 to raise at the same time.
A control device for a front loader, characterized in that a bucket stopper is provided for stopping the scooping operation of the bucket 13 when the pressure switch 71 is in a detection state and when the signal line 79 of the pressure switch 71 is disconnected.
