PROBLEM TO BE SOLVED: To provide a driving system for pretreatment equipment of a combine harvester set to carry out forced rotation of grain culms only at a stopping time of the travel of the combine harvester in reaping work and to stop driving of the pretreatment equipment in reverse movement of the combine harvester. SOLUTION: The driving system actuates a driving motor 92, HST for pretreatment and carrying out the forced rotation only when a reaping lever switch 109 is on (in reaping work state), a back switch 73 is on (a state in which a main speed change lever is placed on a reversing position) and an output of a T/M revolution sensor 111 is [stop] (rotation of an output axle of HST for traveling stops, the combine harvester is stopping), and stops the HST for pretreatment, pretreatment equipment (and hood chain of a thresher) when the output of the T/M revolution sensor 111 is [rotating] (the output axle of the HST for traveling is rotating, the combine harvester is traveling to reverse direction).
