PROBLEM TO BE SOLVED: To provide a working vehicle capable of stabilizing highly loaded field work while saving energy during low-load traveling on road and securing operability.SOLUTION: A working vehicle comprises: a traveling transmission device (12) for transmitting power of variable speed to traveling devices (10, 11) an oil transfer device (73) for hydraulically driving work devices such as a planting part (4) and a prime mover part (20) as a power supply source. The working vehicle is configured such that the traveling transmission device (12) is switchable among a non-transmission "neutral mode," a low-speed "work mode," and a high-speed "on-road mode," the prime mover part (20) includes a high-output electric motor (71) and a low-output electric motor (72), power is supplied by both motors (71, 72) in the "work mode," and shift is possible only to the low-output motor in the "on-road mode," thereby making it possible to support a wide range of power conditions efficiently.COPYRIGHT: (C)2014,JPO&INPIT【課題】高負荷の圃場作業の安定化とともに、低負荷の路上走行の省エネ化および操作性の確保を可能とする作業車両を提供する。【解決手段】作業車両は、走行装置(10,11)に変速伝動する走行伝動装置(12)と、植付部(4)等の作業装置を油圧駆動する送油装置(73)と、動力供給源の原動部(20)とを備え、上記走行伝動装置(12)は、非伝動の「中立モード」と、低速の「作業モード」と、高速の「路上モード」とを切替え可能に構成し、上記原動部(20)は、高出力と低出力の電動モータ(71,72)によって構成し、「作業モード」では、両モータ(71,72)により動力を供給し、また、「路上モード」では低出力モータ(72)のみに切替え可能に構成することにより、幅広い動力条件に対して効率的対応を可能とするものである。【選択図】図5
