The video shows removing the screen, blowing and hosing out the condenser fins, and confirming the repair restored cold air. No parts or money required. Most useful to RK37 owners facing the same symptom, since the creator notes almost no other videos address this exact issue.
Posted by the Marty B's life channel, which appears to be an owner sharing personal tractor and property work from their own land and jobs.
The condenser in front of the radiator gets clogged with dirt and debris, causing high head pressure on the compressor so it does not cool like it should.
The owner noticed the compressor started squealing after bush hogging got dirt and debris into the radiator and condenser, raising head pressure.
Pull the screen out, loosen the three mounting bolts to access the condenser, then blow and hose out the fins until clean, then reinstall the filters.
Yes, after washing out the condenser fins the AC blew cold air again and the compressor stopped squealing, solving the problem.
