It's a short, practical demonstration aimed at owners troubleshooting weak AC performance, not a buying guide or feature overview.
Appears to be an owner sharing a quick, practical fix based on their own tractor, not a dealer or professional technician.
A dusty pre-cleaner filter and dirty cabin air filter are likely the problem. Removing and blowing them out with an air hose can fix weak AC cooling.
Take the pre-cleaner filter out, then unscrew and slide the filter out and blow it clean with an air hose.
The cabin air filter sits up near the pre-cleaner and can be blown out with an air hose, though it may eventually need replacing.
