| Check to see if you have frost on any of the lines. If you have a blockage somewhere you will freeze up depending on which side the blockage is. If Deere dries the system on the low side you will have a accumulator and a orifice tube, if dried on the high side you will have an expansion valve. These A/C units in these tractors worked well, we had one and never touched it. Kind of hard to diagnose without gauge pressures. Deere puts a stupid black cover over compreesor clutch so you can't see it engaging, take that off to get a visual. I did one the other day that worked good at idle but when revd up clutch would slip. Put new clutch kit on and shimmed it properly and worked like new again. When getting gauge pressure note temperature outside, it is relevant to gauge pressure readings. | |
