PROBLEM TO BE SOLVED: To provide a four-wheel drive working vehicle in which arrangement positions of a battery and an engine are devised to enhance traveling stability, as well as to facilitate attach and detach operations of the battery.SOLUTION: A four-wheel drive working vehicle comprises: a seat support frame 24 for supporting a driver's seat disposed on a vehicle body frame. The vehicle body frame comprises: a front machine frame 1A including a floor surface of an operation part; and a rear machine frame 1B disposed behind the front machine frame 1A at a higher position than the floor surface of the operation part. An engine is arranged under the rear machine frame 1B. A battery 9 for supplying electric power to an electric motor 8 is mounted above the front machine frame 1A and under the seat support frame 24. A frame part 28, which is a part of the seat support frame 24, arranged above the battery 9 and at a position opposing the battery 9, is configured to be detachably attached to another frame part 29 fixed to the vehicle body frame.SELECTED DRAWING: Figure 8
【課題】バッテリやエンジンの配設位置を工夫して、走行の安定性を良くし、かつバッテリの脱着操作を行い易くする。【解決手段】車体フレーム上で運転座席を支持する座席支持フレーム24が装備され、車体フレームは、運転部の床面が設けられた前部機枠1Aと、運転部の床面よりも高い位置で前部機枠1Aの後方側に配設された後部機枠1Bとを備え、エンジンが後部機枠1Bの下側に配備され、電動モータ8に電力を供給するバッテリ9が、前部機枠1Aの上側で、かつ、座席支持フレーム24の下側に配備され、座席支持フレーム24のうち、バッテリ9の上側でバッテリ9に対向した位置に存在する一部のフレーム部分28が、車体フレームに固定されている他のフレーム部分29に対して、脱着可能に構成されている。【選択図】図8
