The air conditioner in my MX110 (Limited Model) does not cool the cab on hot summer days as much as I'd like. A couple of years ago I had the dealer check the charge and it seemed a bit better afterwards but still doesn't cool the air like it should. I have to run the air conditioner and fan full blast to just keep it comfortable in shirt sleeves. The manual says there is a heater shut off valve at the back of the cylinder head that can be closed for the summer months when the heater is not needed. I have looked a number of times and have not been able to find this valve. Does anyone know if it is somewhere else on certain models?
Air conditioner not up to par

Thanks for the info RC. That is what the manual says as well, but even sprawled on top of the engine I have yet to find the shut-off valve. There is nothing that I can see mounted in the end of the cylinder head. Is it possible that its in the heater hose or back under the cab?

Should be a pair of heater hoses popping out of the front cab supports. Take a really bright light and start there and see if you can find the hoses, they look just like the hoses used on a car heater. Once you find them, see if they are hot if the tractor has been running. That will mean the valve is open.
I found a product that I substituted for the fake Freon in my AC, made a huge difference and it will now run you out of the cab when on full cold. It is over at a different farm, so when I am over there I will get the name of it and post.

Thanks RC for the additional information. Since our last posts, I had the opportunity to speak to a Case IH mechanic about the location of the heater shut off valve on my tractor....Limited Series MX110. He told me that apparently a few Case tractors were sold without a shut-off valve. He had no idea why that was done, but they have encountered this a few times before. Maybe it was something overlooked during assembly at the factory ????? I understand that one can be installed and I probably will have that done next time the tractor is in for servicing. So,, thank you for your patience and advice. Also thank you for the information regarding the fake freon for the AC. I may give it a try as well. Thanks again.
