<P>PROBLEM TO BE SOLVED: To provide a combine harvester that increases the number of cutting lines without reducing threshing efficiency. <P>SOLUTION: Right and left grass dividing tools (14R, 14L) are designed to be able to freely vary their horizontal spacing. A maximum vehicle speed regulation means (50, 52, 100) for regulating an increase in vehicle speed beyond a set speed when the spacing between the right and left grass dividing tools (14R, 14L) is widened is provided. A maximum vehicle speed setting means (109) capable of varying the set speed is provided. The set speed is automatically varied according to the open or closed state of the right and left grass dividing tools (14R, 14L) within the extent that the amount per unit time of grain culms introduced via the spacing part between the right and left grass dividing tools (14R, 14L) does not exceed the maximum throughput per unit time of a thresher (3). <P>COPYRIGHT: (C)2013,JPO&INPIT |
