    Hi all. The aircon is poor on the tractor. Anyone know what weight of gas to refill the system (I think it 900g +/- 50g) and what should operating pressure be at? Thanks

    I don't know the weight of the refrigerant but the low side on average is 30-40 psi and the high around 7 X the low reading. The ambient temperature makes a difference in your pressure readings also.
