PURPOSE:To improve operability, by carrying out automatic directional control of reaping work in the second reaping work on the basis of manual running locus in the first round and controlling the rapping work in the third round or after on the basis of running locus data in the previous round as the standard. CONSTITUTION:A direction sensor 1 is provided in a combine 2 and reaping work for grain stalk groups is carried out in the first round while manually controlling the forward direction to memorize running locus data. Automatic directional control is carried out for reaping work in the second round on the basis of the manual running locus data in the first round and reaping work in the third round or after is controlled while carrying out automatic directional control on the basis of the running locus data in the previous round. Thereby rapid follow-up control directly connected to the renewed data can be performed.
