Abstract

A position detector is supported to be movable between a first position and a second position lower than the first position. A mounting stay is below the position detector when the position detector is in the first position, and, when the position detector is rotated together with the mounting stay from a state in which the position detector is in the first position, the position detector is moved to the second position and the mounting stay is positioned above the position detector in the second position and covers over the position detector so as to restrain the automatic steering control.

First claim

What is claimed is:

1. A working vehicle, comprising:
a travelable vehicle body;
a position detector to detect a position of the vehicle body based on a signal transmitted from a positioning satellite;
a controller configured or programmed to perform an automatic steering control in which steering of the vehicle body is automatically controlled based on detection information detected by the position detector;
a restraint to restrain the automatic steering control; and
a support bracket to support the position detector; wherein
the position detector is supported by the support bracket so as to be movable between a first position where the position detector is used and a second position lower than the first position;
the restraint is operable to restrain the automatic steering control when the position detector is in the second position;
the support bracket includes a pivotal shaft and a mounting stay rotatable around the pivotal shaft and structured to have the position detector mounted thereon;
the mounting stay includes a plate that reflects the signal transmitted from the positioning satellite so that the mounting stay defines and functions as the restraint; and
the mounting stay is disposed below the position detector when the position detector is in the first position, and, when the position detector is rotated from the first position together with the mounting stay around the pivotal shaft, the position detector is moved to the second position and the mounting stay is positioned above the position detector in the second position and covers over the position detector so as to restrain the automatic steering control.

2. The working vehicle according to claim 1 , wherein
the support bracket includes a base stay including a plate that includes a plate surface, the base stay being attached to the vehicle body side so as to face the plate surface up or down; and
the mounting stay, when the position detector is in the first position, is placed on the base stay and is pivotally supported at a front portion thereof by the base stay via the pivotal shaft so as to be rotatable around an axis of the pivotal shaft extending in a vehicle width direction.

3. The working vehicle according to claim 1 , wherein the mounting stay includes:
a main plate portion attached to the position detector;
a first extending plate portion extending in one lateral direction from the main plate portion; and
a second extending plate portion extending in another lateral direction opposite to the one lateral direction from the main plate portion.

4. The working vehicle according to claim 1 , wherein the position detector includes a detection sensor to detect that the position detector is in the second position.

5. The working vehicle according to claim 4 , further comprising a display to indicate that the detection sensor has detected the second position.

6. The working vehicle according to claim 2 , further comprising:
a cabin mounted on the vehicle body and provided with a roof at an upper portion thereof; and
a first bar and a second bar each of which extends along the vehicle width direction above the roof and which are juxtaposed forward and rearward; wherein
the base stay is fixed to the first bar and the second bar.
