DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a simplification of an operation monitor panel in a riding rice transplanter.

[0002]

2. Description of the Related Art A riding rice transplanter is provided with a pair of left and right drawing markers for drawing a position passing through the left and right centers of the body in the next step on the surface of the field when performing the operation while turning the field. A drawing marker operation lamp for indicating which of the pair of left and right drawing markers is in the active state is provided on the driving monitor panel.

When a pair of left and right direction indicators for instructing a direction to change direction when traveling on a road are in a position invisible to an operator, a direction indicator lamp for indicating which of the left and right direction indicators is in an operating state. Must be provided on the monitor panel.

[0004]

If the drawing marker operation lamp and the direction indicating lamp are provided on the monitor panel, not only the monitor panel becomes complicated, but also since both lamps are provided as a pair of left and right lamps, the operator confuses both lamps. There is a risk of misjudgment, and how to provide the drawing marker operation lamp and the direction indicating lamp on the monitor panel is a design problem. Therefore, an object of the present invention is to make a drawing marker operation lamp and a direction indicating lamp coexist while simplifying a monitor panel.

[0005]

Means for Solving the Problems In order to solve the above problems, the present invention is configured as follows. That is, the riding rice transplanter according to the present invention has a pair of left and right line drawing markers for drawing a position where the body passes in the next stroke on the surface of the field when performing work while turning the field, and indicates a direction to change direction when traveling on the road. In a riding rice transplanter equipped with a pair of left and right direction indicators, which function as a drawing marker operation display lamp for allowing the operator to perceive which of the pair of left and right drawing markers is in operation during seedling planting work, When the vehicle is traveling on a road, a display lamp functioning as a direction instruction display lamp for allowing an operator to perceive which of the pair of left and right direction indicators is in an active state is provided.
