AC issues with a tractor

Have you looked at your ac condenser and radiator to see if it is clean and not have Debree blocking your condenser and have good air flow going through it? Because a dirty or obstructed ac condenser will cause the problem you are having. while you have it running with gauges on it put a fan in front of it blowing on the ac condenser and see if the pressures will level out and the air will bow colder.
You may need a little more air flow across the ac condenser.
Some things like this is hard to diagnose without being there looking at it in person.

Condenser is at the front of the radiator/intercooler/condensor stack and it is absolutely spotless. I will have to try the fan at the front of the tractor, but with a clean condenser and a direct drive fan, I would think air flow wouldn't be a problem at 1500rpm, but I can give it a shot. If anyone has any other ideas or areas to look at, keep me posted!
 
What is the pressure on the gauges low and high sides before you turn on the ac?
What is the pressure on the low and high sides with the ac running at idle?
Probably the best thing to do is find someone to flush the ac system and start over from scratch sound like it has been worked on by a few people.
Since i went to using ac machines to charge and they will flush and you can see how much oil comes out of it also it recycles the freon i have had better results with cooling also i have very little waste of freon if something isn't right.
My son just went to a ac class for JD tractors they showed him a neat trick to check the expansion valve with a canned air. Turn the can upside down and spray the expansion valve with the liquid that comes out of the can and watch the gauges if the pressures change it is working if the pressure doesn't change it is bad.

I will put some gauges on it, and double check those numbers.

That sounds like a pretty cool trick.....see what I did there?
