Kubota L4200 Air Conditioner

[Birdford]

I'm getting very little air from the vents on the L4200. Air is cold but isn't blowing hard enough to fight off the heat coming this way. I've cleaned the filters around the radiator. Is there an in cabin filter, and if so, how does one go about getting to it? Any ideas on fixes would be greatly appreciated!

According to the diagram in the workshop manual, your cabin filters are located on top of the roof (Rear).

Providing the ROPs are OEM and not aftermarket.

Your low airflow is most likely caused by the evaporator core being plugged so the fan can not move air through it. Even if the filter is plugged, the system should recirculate the cabin air and have decent airflow.

The diagram is misleading, I believe it is still under the roof rear side. Follow the assembly line, it directs to under the roof.



If the roof has a crack anywhere, it can compromise the filtered air supply. Many Kubota captive roofs are hollow to allow filtered air to circulate.

As a non mechanic, I appreciate these tips. I'll try to locate the evaporator core and check filters. I just don't wanna start blindly taking things apart without knowing what to look for. Thanks!

You will probably find it easier to pull the roof. The perimeter screws and it lifts off. Like Whitetiger said, the evap is probably clogged with dust. Remove the coverings from the housing(Without opening ac lines fittings) and try to reverse blow out the evap-core.

I will give it a try.

Found the cabin filter. It looked horrible. Now I'm trying to locate the evaporator. Any tips as to where it's located?

Found it and it was filty. Can you tell me where the evaporator is located and how hard it is to get to? Thanks
