<p>A valve control structure for a working vehicle comprising a control lever rockable crosswise, a first input rod pushed and pulled by rocking movements in a first direction of the control lever, a second input rod pushed and pulled by rocking movements in a second direction of the control lever, a first output rod connected to a first valve, a second output rod connected to a second valve, and an interlock switching device including bellcranks provided between the input rods and the output rods. The interlock switching device is operable to switch interlocking relationship between the input and output rods through the bellcranks. In one interlocking relationship, the first valve is controlled by rocking movements in the first direction of the control lever and the second valve by rocking movements in the second direction of the control lever. In the other interlocking relationship, the second valve is controlled by the rocking movements in the first direction of the control lever and the first valve by the rocking movements in the second direction of the control lever.</p> |
