PROBLEM TO BE SOLVED: To enable a controller of an implement to be substituted with the inexpensive one not required to correspond to a high speed by reducing a treatment load on the controller of the implement in a farming tractor for carrying out a traveling operation by linking the implement such as various kinds of distributors for operation. SOLUTION: The main controller 16 installed in a tractor body has a calculation means for calculating the traveling speed of the tractor body 1, and an output means for outputting a prescribed implement-controlling signal E corresponding to the value of the calculated traveling speed. Preferably, the implement-controlling signal E is a low-frequency pulse signal directly proportional to the calculated traveling speed. COPYRIGHT: (C)2008,JPO&INPIT
