<p>AIR FILTRATION SYSTEM FOR HARVESTER OPERATOR CAB An air filtration system for the operator's cab on a self-propelled crop harvesting machine is disclosed wherein the service door for access to the filter cartridge is positioned above the access door into the cab enclosure. Since the open position of the service door interferes with the opening of the cab access door, the filter cartridge cannot be changed unless the cab door is closed. A movable latch engagement member is engageable with lift members affixed to the service door to lift the latch engagement member out of an engageable position with the door latch to prevent the service door from being latched unless a filter cartridge is positioned within the filtration chamber. The filter cartridge restricts the movement of the latch engagement member to permit engagement thereof with the door latch. The resultant structure provides an air filtration system that requires a filter cartridge within the filtration chamber before the service door can be latched.</p> |
