Aside from that if your tractor does catch fire someday (in happens, and nobody plans for it), you have just provided a high pressure hydrocarbon injection system - can you say "adding fuel to the fire."

Check to see if the evaporator is freezing up, the evaporator is the one in the cab by the fan. Also, check to see that the sensing wire from the thermostatic switch- the one in the cab by the fan switch- is stuck into the evaporator through all the cooling coils. While you are at it make sure it-the sensing wire- is not cracked where all the gas escaped. If you park it, is there a puddle of water under the evaporator tray drain lines? If there is, it likely came from ice on the evaporator. Is the evaporator matted over with crud? Keep the windows closed if the fan is running and you are recirculating cab air.

We've got a licensed mechanic that does all of our work we won't touch. Maybe it's due to the area or the equipment we operate. But if the systems leak out over winter storage then I'll use something a little bit cheaper than than topping up with freon every year. My iron is as old as the hills.
Before parking it when your done, pressure wash and degrease everything to do with the AC, look for the oily spots next spring, that's the leak. Not to brag, but before I learned to fix AC myself, we paid the local garage twice to "FIX" the AC in our MF 4880, still leaked when they were done, paid the local Agco dealer at least twice as well to "FIX" it, still leaked, did it myself and went two years then only needed half a pound to get it full. Found a faulty o-ring in the quick disconnect at the cab, for about 10 bucks I just went ahead and replaced all the o-rings in the entire system.
