PROBLEM TO BE SOLVED: To solve problems in cost and labor that, since there is no mechanism for taking out a power from an engine installed on its vehicle body in the conventional combine harvesters, the power can not be utilized in a working machine other than the combine harvester, and e.g. in using a vehicle-cleaning pump, it is necessary to provide another engine. SOLUTION: This supplemental working machine-mounting unit is constituted by installing a clutch device 5 capable of freely engaging and disengaging in a transmission passage to a discharging screw shaft 4 installed at the inside of an open type grain tank 3 installed on a traveling vehicle body 2. When the above grain tank is set to be in an open rotation, it is possible to join and mount the vehicle-cleaning pump 6 instead of the grain tank 3 to the above clutch device 5 as capable of transmitting power and freely engaging and disengaging.
