THANK YOU ALL for the help, tips and guidance.
Sounds like I need to clean the components and see if it makes a difference. I have had my B3000 for about 1 -1/2 years and have not cleaned the A/C parts in the roof (condenser?). I have no idea if it was ever cleaned in the past.
Unfortunately, I have to remove the roof to get at the condenser.
Not sure what I need to remove to get the roof off. I'll look at the parts diagram to see if it shows what screws/bolts need to come out.
The cab fresh air filter was replaced last Feb.
If the 134a is clear and I can't really see it, how can I tell if I am low, or just can't see the liquid thru the sight glass?
If yours is like mine (and I presume it it), inside the cab, if you look up, there will be a number of Phillips head screws around the edge of the inner headliner. Every other one needs to be removed to remove the roof Problem is, which every other one.....
Simple. Remove one. If it's long it's a roof screw. If it's short, it's a headliner screw. All the long ones have to be removed to get the roof off. In my case, it's 10 screws. Yours may be different.
Cleaning the evaporator is a real pizzer. Lots of stuff up there (depending on what options you have), I have all of them. if your unit is like mine, you won't be able to completely remove the upper shroud without removing the heater core and on mine at least, the heater core is hard piped so what I did was take out all the screws on the upper shroud and prop it open with a 6" long block of wood (which gives you access to the evaporator but you cannot remove it from the housing without breaking the refrigerant lines so..
What I did was take my garden sprayer and put in some Purple Zep and soaked the evap down with ZEP. Every year mine gets loaded with fine chaff. I soak it down and let it 'cook' for about 15 minutes and refill the sprayer with clear warm water and flush out the evap with that. The crud and dirt will drain out the condensate tubes that go under the tractor. Keep rinsing until the water is clear, button it back up and reinstall the roof. The roof is very lightweight, just bulky. While you are up there, take an air gun and blow off everything, the dust will be everywhere up there. You might want to remove all the connectors and put di-electric grease in them, I did the first time.
I also flipped the roof over in the shop and applied Reflectix foil-bubble-foil insulation to the underside of the roof. There is no insulation and it gets hot in the sun and your ac has to overcome that heat. The Reflectix really cuts the heat load on your ac. You can buy it by the roll at Lowes and it's cheap. I cut mine to size with scissors and glued it to the underside of the roof with 3M contact spray cement.
Like I said previously, my ac is super cold. I think reducing the under roof heat had a lot to do with it too. Just be acreful with the roof. I priced a new one from Kubota. Granted mine is larger but a new one is 13000 bucks.
