I still haven't gotten my tractor yet, but it did arrive at his dealership. It's a 2022 model, and when I asked him if he did the upgrade to the AC, he replied that it already has the new AC system. But it's also leaking, so he's fixing that and hopefully I'll have it next week.
There is a group on Facebook called "Massey Ferguson 4700 Global Tractors" that has a discussion about the AC system and the upgrade kit.
Here is a copy of what somebody said
"Enhancement kit for 4707 Standard cab….
#ACX3795510 $2165.00 Main Kit
ACT0079330 $143.00 Filter Hsg Template
ACT0079340 $128.00 A/C Unit Template
Should be the part numbers needed for the non-visio roof tractor. I remembered that you also have to evacuate the Freon from system beforehand and recharge afterwards."
In another thread about the AC system, they talk about the heat valve not shutting the coolant off to the heater. From what I understand, you have to turn off the valve so the hot water from the engine stops going into the heater. Here is a video link that one of the dealers made to show where it's at.
