When first crank tractor AC compressor comes on, and cools, then in a minute compressor cuts off, and stop cooling. Has anybody got a suggestion what is wrong

You are low on refrigerant. First absolute guess, is that you have a low pressure sensor of the suction side, and as the system gets going the pressure on the low side drops to the point the compressor is shutting off.

won't take refrigerant unless compressor is running, dont' run long enough

Thanks! jigs-n-fixtures, Is anybody else got any suggestions

Suggestions?

Start with a set of gauges. You need information on what's happening within the system, not just an absolute first guess. Air conditioning repair isn't really "homeowner maintenance". If you're going to just guess at what's going on, you'd be better served to find someone with experience.

THAT'S CORRECT so we should talk about your experience before doing anything and risk making it worse. Telling you to bleed gauges and hose assumes you've been shown how. Like cutting hair,telling how and showing how are entirely different animals.
High pressure can and often does cut compressor out so check condenser and clean if needed and make sure condenser fan(s) is running full speed. Both high and low pressure switches can be bypassed but can grenade compressor if you don't know what you are doing and why.

Harry in Ky thank you! I have no gauges, so I just guess, I can put freon in. I would have to hire somebody to come do it and they will charge me a service call. I thought maybe it might be a fuse or switch some little something.
I guess it is going to cost me a lot of money!!!

Have you made sure the condenser in front of the radiator is clean?

I would expect that your tractor takes R-134 not freon.
You can get a can at any auto store or even Walmart that will have a gauge attached.
Unless you have a bad switch it is most likely low on gas and the low pressure switch is cutting off the compressor.
Follow the directions on the can as to how to hold the can, some you will start out up right then invert for a few seconds
and repeat. Many of those will have a small amount of a stop leak and compressor oil and a seal conditioner.

And they will take some refrigerant when not running, many 134 system low pressure switches will activate between 10-25 psi.

I finally got 2 cans in it, still don't work. I have clean radiator, condenser,air filters and everything with no avail. I haven't got the money but guess have to call mechanic
