Somethings not right. I've used a friends M135 for haying in 100+ degree temps and it'll freeze you out of the cab. I'd have your service manager get the regional product rep involved.

I would be checking that the AC recirc feature is working. i.e. There is usually a button on the heater AC control panel that engages recirc. This re runs air from inside the cab through the cooling coil so over time you get colder and colder air coming out the diffusers If you are trying to cool with hot humid outside air you will get the symptoms you are experiencing. A lot of the cooling capacity is being used up in removing the humidity in the outside air. The owner's manual may have a section telling you what to look for (bubbles) in the sight glass on the top of the AC receiver ( cylindrical tank near the condenser). This is a simple diagnostic test for the owner.

I'd recommend installing manual shut off valves in one or both heater hoses.

I know people that have done this on their vehicles too and claim it aids in cooling since no hot coolant is getting to the coil.

I have a new 126GX and same thing it just does not cool enough for me. Kubota has looked at it and said that it was overcharged, They fixed it supposedly. I don't feel any difference. I honestly think its because of the new cabs on the GX tractors there's just so much glass on them and the new location of the a/c vents around the steering wheel is a terrible place in my opinion. I have a 2007 M96S and the vents are above in the cab and that tractor will freeze you out. I believe the cab is just to big and the placement of the vents it just cant cool it off enough, plus its over 100 degrees here in south texas

I have nothing advise wise on ac , but if you can't get it cooler , Have the windows tinted with a reflective tint. I know a guy that has a weak a/c in a Zetor and he had the windows tinted so it would be easier to cool the cab. Plus it keeps the inside of the tractor from sum fading so much.
