PROBLEM TO BE SOLVED: To provide the subject device capable of stably sending a liquid in a prescribed fertilizing amount without linking the rate of an ejecting pump to the load change in a working machine side by driving the ejection pump with a specific motor. SOLUTION: This fertilizing device mounted to a traveling agricultural machine and capable injecting a fertilizer into a soil by an ejecting pressure of an ejection pump is provided by driving the ejection pump 22 with a hydraulic motor 18. In this case, it is preferable to drive the hydraulic motor 18 with a hydraulic pressure taken out from a hydraulic system for a steering. Thus, it is possible to obtain a prescribed fertilizing amount independently and not affected by the speed change of the number of rotation of a rotary, also it is possible to obtain a constant fertilizing amount without being effected by the number of engine rotation, further it is possible to send a liquid in a fertilizing amount linked with a traveling speed, and a fertilizing work in a good efficiency becomes possible.
