Self-propelled operating machine

摘要

A self-propelled operating machine has a power source, a hydraulic CVT for varying power outputted from the power source, and a transmission mechanism connected to the hydraulic CVT for transmitting power outputted from the hydraulic CVT. A stand is mounted between the transmission mechanism and the power source so as to enclose the hydraulic CVT. The stand has an oil passage through which hydraulic oil of the hydraulic CVT flows. A cooling fan cools the oil passage of the stand to thereby cool the hydraulic oil of the hydraulic CVT flowing through the oil passage. The cooling fan is disposed between the power source and the hydraulic CVT so as to be enclosed by the stand.
