PROBLEM TO BE SOLVED: To provide a working vehicle in which a main frame configuration is made a sufficient structure in terms of strength.SOLUTION: A working vehicle is characterized as follows: a transmission case 12 internally mounted with a transmission for shifting gears in a driving force of an engine 20 is fixed in a traveling vehicle body 2 provided to a main frame 15 having a front wheel main frame 15a and a rear wheel main frame 15b in left and right, respectively, and the main frame 15 of the traveling vehicle body 2 a front side travelling transmission case 81 for transmitting the driving force to left and right front wheels 10 is disposed on the side part of the transmission case 12, and the front side travelling transmission case 81 is fixed to the main frame 15 and a fertilizer 5 disposed in the rear side of the main frame 15, a leveling rotor 27 and a rear side traveling transmission case 82 for supplying the driving force to left and right rear wheels 11 are disposed, and the rear side travelling transmission case 82 is fixed to the main frame 15. Accordingly, the strength of the whole working vehicle can be increased more than before without using extra strength members.COPYRIGHT: (C)2015,JPO&INPIT【課題】メインフレーム構成を強度的に十分な構成とした作業車両を提供すること。【解決手段】それぞれ左右に前輪メインフレーム15aと後輪メインフレーム15bを有するメインフレーム15に設けた走行車体2と、該走行車体2のメインフレーム15にエンジン20の駆動力を変速する変速装置を内部に装着したミッションケース12を固着し、ミッションケース12の側部に、左右の前輪10に駆動力を伝動する前側走行伝動ケース81を配置して、該前側走行伝動ケース81をメインフレーム15に固着し、メインフレーム15の後側に配置される施肥装置5、整地ロータ27及び左右の後輪11に駆動力を供給する後側走行伝動ケース82を配置して、該後側走行伝動ケース82をメインフレーム15に固着したので、余分な強度部材を用いること無く、作業車両全体の強度を従来より強くできる。【選択図】図4
