PROBLEM TO BE SOLVED: To provide a combine harvester, in which an oil filter is arranged by considering the heat which is transferred to the surroundings at the time of a temperature rise of hydraulic oil.SOLUTION: A combine harvester comprises an airframe, a hydraulic oil tank, a hydraulic pump, an oil filter, a separation part and an aspiration device. The airframe has an engine mounted thereon. The hydraulic oil tank reserves the working oil. The hydraulic pump feeds the working oil reserved in the hydraulic oil tank, along a hydraulic oil tube. The oil filter removes a foreign material from the working oil flowing from the hydraulic oil tank to the hydraulic pump. The separation part separates the dust from the air to be sucked from the outside. The aspiration device sucks and discharges the dust separated by the separation part. The oil filter is arranged in the vicinity of the position at which the aspiration device discharges the dust.SELECTED DRAWING: Figure 8 |
