<p>PROBLEM TO BE SOLVED: To dispose a residual quantity sensor in a small tank with the minimum capacity in a granular powder tank including a plurality of funnel-shaped small tanks adjacent to each other, to quickly detect that the residual amount of granular powder is small as a sign for replenishing the respective small tanks of the granular powder tank with granular powder.SOLUTION: A working machine includes a granular powder discharge machine provided with transfer pipes which transfer granular powder for a plurality of lines in a granular powder tank (85) to a farm field. The granular powder tank (85) includes a plurality of funnel-shaped small tanks (85a, 85b, ...), and a residual quantity sensor (115) for detecting that the residual amount of granular powder is small is disposed in the minimum-capacity small tank (85a) among the small tanks (85a, 85b, ...).</p> |
