ABSTRACT:
An enclosed cab on a combine harvester has an HVAC unit and fresh air filter affixed to the exterior of the lower rear panel. The fresh air is brought through the filter and into the HVAC unit. The air is then inserted into the cab by a distribution duct. A return air filter is positioned above the lower panel so as to minimize particulates entering the return system. The engine coolant line and refrigerant line can be slid out of the unit without the need for breaking the lines.
