PROBLEM TO BE SOLVED: To solve a problem that a transportation apparatus of threshing depth arrangement in which grain culm transported to a joint part is passed, transported and supplied to a thresher has constitution that the rear part can be lifted and lowered with the front part as a rotation fulcrum depending upon the length of grain culm and when a supporting means supporting a nipping rod apparatus is largely adjusted to a shortly threshing side, the supporting means is brought into contact with the traveling crawler of a traveling apparatus and adjustment of the supporting means to the shortly threshing side by a fixed value or above was impossible. SOLUTION: The supporting means 10 for supporting the nipping rod apparatus 11 of a threshing depth adjustment and transportation apparatus 9 for supplying grain culm to the thresher 14 adjusting supply depth has constitution that when the threshing depth adjustment and transportation apparatus 9 is operated to the shortly threshing side of fixed position, the supporting means has a superposition state to the traveling crawler 15a on the side view. A second threshing depth adjustment and transportation apparatus 13 is installed behind the threshing depth adjustment and transportation apparatus 9. COPYRIGHT: (C)2003,JPO
