Fixing an A/c on a John Deere tractor

This is a real-world repair job on a high-hour (8,467) John Deere 6125M orchard tractor with a non-working A/C, not a general overview. The technician diagnoses low refrigerant, vacuums the system, checks for leaks, recharges it, and reads actual high/low side pressures to identify a likely bad expansion valve. Useful for owners troubleshooting A/C issues on similar Deere tractors rather than shoppers researching the model.

Appears to be a field mechanic or repair service documenting an actual customer job, not a dealership or marketing channel.
