The present invention relates to a paddy field working machine. According to the paddy field working machine of the present invention, a supply interval of a working device is appropriately set without being affected by slip of a wheel. In addition, a supply interval of an agricultural material can be appropriately set. The power of a transmission is branched in parallel with a driving electric system and a working electric system so power of the driving electric system is transferred to the wheel, and power of the working electric system is transferred to the working device through a continuously variable transmission (45). The paddy field working machine of the present invention comprises: a slip ratio detection unit (68) for detecting a slip ratio of a wheel； and a control unit (69) controlling a continuously variable transmission (45) on the basis of the slip ratio detected by the slip ratio detection unit (68) to control a supply interval (L). The paddy field working machine of the present invention further comprises: a transmission for receiving power of a primer moving unit； and a working device for intermittently supplying an agricultural material to the soil of a rice paddy at a preset supply interval. The power of the transmission is branched in parallel to the driving electric system and the working electric system, and the power of the driving electric system is transferred to the wheel for driving, and the power of the working electric system is transferred to the working device through the continuously variable transmission (1045). Also, a working revolution detecting unit (1065) for detecting the revolution of the power from the continuously variable transmission (1045) is provided at a downstream side of the continuously variable transmission (1045).수전 작업기에 있어서, 차륜의 슬립의 영향을 받을 일 없이, 작업 장치의 공급 간격이 적절하게 설정되도록 한다. 또한, 수전 작업기에 있어서, 농용 자재의 공급 간격을 적절하게 설정할 수 있도록 한다.변속 장치의 동력이 주행 전동계 및 작업 전동계에 병렬적으로 분기되어서, 주행 전동계의 동력이 주행용의 차륜에 전달되고, 작업 전동계의 동력이 무단 변속 장
