得る変速レバー７１を設け、前進アーム８７ａと
後進アーム８７ｂの係合溝を前記変速レバーに左
右方向から対向させ、ガイド溝の中立位置を形成
する横溝部分の中間で非伝動、その左右位置で前
進待機又は後進待機に切換わり、前後操作で前後
進増速変速となるようにしたコンバインにおいて
、前記前進アーム８７ａと後進アーム８７ｂの係
合溝を有する部分は上下に偏位させると共に前端
部を変速レバー７１の長さ方向から見て重複させ
、両アーム８７ａ，８７ｂの基部は上記変速レバ
ー７１の一側で単一の支軸にて枢支したことを特
徴とするコンバインにおける走行操作装置。 A shift lever 71 that can be tilted forward, backward, left, and right is provided on the operation panel of the driving section, and the engagement grooves of the forward arm 87a and the reverse arm 87b are opposed to the shift lever from left and right to form a neutral position of the guide groove. In a combine harvester in which transmission is not carried out in the middle of the lateral groove portion, switching to forward standby or reverse standby occurs at the left and right positions, and forward and backward speed increase is achieved by forward and backward operation, the engagement grooves of the forward arm 87a and the backward arm 87b are formed. The arms 87a and 87b are vertically offset and their front ends are overlapped when viewed from the length direction of the shift lever 71, and the bases of both arms 87a and 87b are pivoted on one side of the shift lever 71 by a single support shaft. A travel control device for a combine harvester, characterized by:
