Abstract: A working vehicle includes a cabin and an outside air inlet portion. The working vehicle further includes: a filter device having: a first filter providing a first filtering level; and a second filter providing a second filtering level that is a filtering level higher than the first filtering level; an air conditioning unit to which the outside air having passed through the filter device is supplied; and a filter changing mechanism having: a first state to allow the outside air to pass through only the first filter; and a second state to allow the outside air to pass through at least the second filter among the first filter and the second filter, the filter changing mechanism being configured to be selectively switched to the first state or the second state.
