Buying Advice Most Reliable A/C

Usually it means the radiators need a deep cleaning and rinsing. Remove everything you can from the surrounding area you dont want to get wet. Carefully squirt a jet of water through the fins. Do not angle the jet, or it will bend the fins. You will be amazed at how much accumulates in there. I rinse mine a good 1/2 hour or more until clean water comes out. In the beginning, it will look like mud coming out. The bottom will be the worst.
My AC always works good and I have had a bunch of Kubotas Over the years and have 2 now.

Thanks everybody! My in-laws row crop farm with JD tractors and case combines. The air works great on all of them. Then...there’s my little 5030 I keep at the house. I don’t use it except to bushhog, clear some brush, and grade the driveway. That’s why I’m not sure how reliable the air is on this size tractor.

We have done (or had done) almost everything on your lists. We are good at everyday maintenance. We’ve had the roof off, cleaned and/or replaced almost everything (including compressor). We’ve topped off the refrigerant. I’ve been against tinting the windows because of the visibility, but maybe I just need to do it. I haven’t, however, thoroughly cleaned the radiator. I’ll try that. I also didn’t think about the lack of insulation in the roof, so I’ll try that too.

Buuuuttttt...should this not work, the wife had given the ok to look at replacements, so I’m thinking about shopping. I’m in Southern Missouri, so it’s not that hot yet. It seems though that most cab tractors in the 50-75 hp range are reliable as far as A/C goes.

Any other input is welcome. I certainly appreciate it!

I use my pressure washer with the wide fan low pressure nozzle the clean the rad and the condenser and in my case the charge air cooler as well. Mine gets cleaned everyday when I come home from the field. Hay making causes a ton of chaff.
