PROBLEM TO BE SOLVED: To provide a combine in which an engine output corresponding to load during the running of the combine for reaping is obtained and the occurrence of noise is reduced by suppressing the increase in the number of rotations of an engine in a low speed running.SOLUTION: A controller is provided so that the number of rotations of the engine 52 may be rapidly increased up to a first target number of the rotations of the engine which is set in an accelerator dial 104 when a main gear shift lever 95 is shifted from a neutral range to a forward side or backward side in a condition that a sub gear shift lever 97 is shifted to high speed side, and the number of the rotations of the engine 52 is increased according to the operation position of the main gear shift lever 95 when the main gear shift lever 95 is shifted from the neutral range to the forward side or backward side in a condition a sub gear shift lever 97 is shifted to low speed side.COPYRIGHT: (C)2013,JPO&INPIT【課題】コンバインの刈取走行時の負荷に応じたエンジン出力を得ると共に、低速走行時のエンジン回転数の上昇が抑えて騒音の発生を低減する。【解決手段】副変速レバー97が高速側に切り換えられた状態で、主変速レバー95が中立域から前進側又は後進側に操作された場合に、エンジン52の回転数をアクセルダイヤル104で設定された第1目標回転数まで急増速させ、副変速レバー97が低速側に切り換えられた状態で、主変速レバー95が中立域から前進側又は後進側に操作された場合には、エンジン52の回転数を主変速レバー95の操作位置に応じて増速させる制御装置を設ける。【選択図】図1
