OK - mostly good news over here. We had some warmer daytime temps with sun yesterday ~75-80F, and I ran the tractor for a bit. I got it good and heat soaked, then stopped and turned on the AC to max, RPMS to 1500 and hooked up the gauges. I had added 12oz of R134A (one single can...) and did...

I think before I condemn anything based on the above, I ALSO need to hook up the gauges again when it's hot out tomorrow during the daytime. I'm wondering if the cool temps (65F, after dark....no sun...) are what's causing the short cycling...

OK, more fun tonight! Charged the system. No issues there, as I've done so before on other R134A systems. AMBIENT TEMPS WERE AROUND 65F TONIGHT WHILE DOING THIS TESTING AND FILMING FYI! Still having odd behavior post-charge: - When AC system is set to "OFF" with the engine running, the...

Right right, I wonder if the clutch is getting hot and that's what is causing the drag! Meant to post this too. Here's the snippet out of the M7060 FSM on low/high side pressures. It's missing any reference to ambient temp, so I also included one from the internet that does for R134A systems.

Alright, ran the tractor for a bit last night. Sun down, 72 degrees F, so not exactly rough conditions for the system. No loss of cold air even after a good 40 minutes of use. I hooked up my manifold after things had been thoroughly heat soaked for those 40 minutes anyways, and here's what I...

Thanks everyone for the replies! I really appreciate it. I think based on all the feedback here and some more thinking about the issue over the weekend, my next step will be to hook up the gauges when this issue occurs again. I have the base readings mentioned in the first post, but I don't...

Appreciate the response! Ok I follow and can give that a try, but would that explain the compressor behavior?

Tractor: M7060 HDC12 Symptoms: A/C works fine and blows cold for about 20-30 minutes, then stops blowing cold. Next time i take out the tractor, the AC works fine again on startup, but after the same 20-30 minutes, it stops blowing cold again. If I keep the A/C on after it stops blowing cold, I...
