たことを特徴とするフロントローダの制御装置。 In a control device for a front loader, a bucket solenoid valve 42 of a bucket cylinder 14 is driven by a bucket manual control signal d so that a bucket 13 is scooped and dumped in response to an operation of an operation unit 26. A dump end detection means 71 is provided to detect when the bucket has reached the stroke end, and an automatic control means 75 is provided to output a bucket automatic control signal e that causes the bucket 13 to alternately repeat the scooping and dumping operations. By operating the switch 79 to the automatic side, after detection by the dump end detection means 71, the bucket solenoid valve 42 is switched from the manual mode in which the bucket solenoid valve 42 is driven by the bucket automatic control signal e. A control device for a front loader, characterized in that it is provided with mode switching means 78 for switching to an automatic driving mode.
