PROBLEM TO BE SOLVED: To provide a working vehicle improved in working efficiency by improving the operability of a PTO shift lever.SOLUTION: An engaging member 56 is fitted into a guide groove 61a formed near the center of an arm 61 linked with a normal rotation side link member 57c, and into a guide groove 62a formed near the center of a guide plate 62. An arm 60 linked with a reverse rotation side link member 57b has a slotted part 60b opened at the upper end. Only when a PTO shaft 26 is reversely rotated by the operation of the PTO shift lever 20, the engaging member 56 is fitted into the slotted part 60b, and only when the PTO shift lever 20 is put in the neutral position, the PTO shift lever 20 is vertically turnable. An elastic member 59 comprises an adjusting member 58 capable of adjusting an energizing force.COPYRIGHT: (C)2008,JPO&INPIT【課題】PTO変速レバーの操作性を改善して、作業性を向上させた作業車両を提供する。【解決手段】係合部材56を、正回転側リンク部材57cに連係するアーム61の中央近傍に設けたガイド溝61aと、ガイド板62の中央近傍に設けたガイド溝62aとに嵌入させる。そして、逆回転側リンク部材57bに連係するアーム60は、上端部を開口した切込部60bを有し、PTO変速レバー20の操作によりPTO軸26を逆回転させるときにのみ、係合部材56が切込部60bに嵌入し、PTO変速レバー20を中立位置にしたときのみ、PTO変速レバー20を上下方向に回動可能とする。また、弾性部材59は、付勢力を調節可能とする調節部材58を備える。【選択図】図6
