PROBLEM TO BE SOLVED: To provide a combine harvester preventing its traveling comfort from being made poor when constructed in such a way that, its engines mechanical power is branched in parallel to a traveling transmission system and a reaping transmission system, and the power of the traveling transmission system is transmitted to the traveling gear, while the power of the reaping transmission system to the reaping section so as to allow the power of the traveling transmission system to be shutdown.SOLUTION: The combine harvester includes a machine body-halting means operable to the mode of transmitting the power of the traveling transmission system to the traveling gear or to the mode of transmitting the power of the traveling transmission system to be shutdown, a manually operating tool 94 operable to the mode of the machine body-halting means to be put to transmission or shutdown, a means 105 of detecting the speed of the machine body, and a means of hampering the operation of the machine body-halting means to its shutdown mode when the machine bodys traveling speed is higher than a preset speed.COPYRIGHT: (C)2010,JPO&INPIT【課題】エンジンの動力を走行伝動系と刈取伝動系とに並列的に分岐させて、走行伝動系の動力を走行装置に伝達し、刈取伝動系の動力を刈取部に伝達するように構成して、走行伝動系の動力を遮断可能に構成した場合、乗り心地の悪化を防止する。【解決手段】走行伝動系の動力を走行装置に伝達する伝動状態、及び走行伝動系の動力を遮断する遮断状態に操作自在な機体停止手段を備える。機体停止手段を伝動及び遮断状態に操作自在な人為操作具94を備える。機体の走行速度を検出する速度検出手段105を備え、機体の走行速度が事前に設定された設定速度よりも高速であると機体停止手段の遮断状態への操作を阻止する牽制手段を備える。【選択図】図4
