PURPOSE:To maintain a proper oil level at all times, by arranging an oil tank communicated with a transmission case in a longitudinal direction of a body in such a manner that an upper surface of the oil tank is slightly higher than an oil level in the transmission case. CONSTITUTION:In a working vehicle such as a combine, a transmission case 12a containing an oil to be supplied by a hydraulic pump 32 to hydraulic equipments 37 and 35 is communicated through a bypass pipe 47 to an oil tank 15. The oil tank 15 has an upper surface 15a located in a level substantially the same as an oil level L in the transmission case 12a or slightly higher than the oil level L, and the oil tank 15 is arranged in a position substantially the same as the position of the transmission case 12a in a longitudinal direction of a body as viewed in plan. With this arrangement, even when the transmission case 12a is inclined in the longitudinal and transverse directions of the body, the oil level L is less fluctuated to thereby prevent insufficient lubrication of hydraulic clutches 16 and 17 or the like and also prevent temperature rise or the like of the oil. Further, in the case that a filter 41 is located above the oil level L, it may be exchanged without draining the oil. |
