Abstract: An air handling system for the cab of a skid steer loader has an airflow housing mounted on the exterior of the cab and on a rear wall thereof. The housing is within the profile of the loader, that is, below the upper wall of the cab and within the side frame members. The housing has an air inlet above the engine compartment, and includes a heater core and an air conditioning evaporator, both of which act as heat exchangers mounted in a plenum chamber in which two fans are mounted. Ducts lead from the plenum chamber to the interior of the cab. The ducts connected to the air handling housing open through ports in the rear wall of the cab into the interior, and interior or the cab ducts carry the air from the plenum chamber to desired locations of the operator's cab for heating, air conditioning or ventilating.
