I love this web sight, it has been helpful....Im truly a city slicker, I bought my B3030 just because it has air, I only have 8 acres but I hate the heat, I dont have any attachments, just a belly mower. I bought this tractor new in 2007, I only have 150 hours, and I have put more freon. But it still is not blowing cold, really warm at best! anyone one have any ideas? I have cleaned all the screens and air filters, thanks to the forms on this web sight.

Its is running off and on?
There are 2 lines from the compressor. A larger one(suction) and a smaller one(pressure). With your hand and the compressor running check each hose for temp. When things are running right the suction will be cool if not cold to the touch and the pressure will be quite warm almost hot. There should be a sight glass usually around the receiver/dryer. It should be checked for bubbles and oil streaking.
Will need more specific info to give any kind of assessment. Could be low on juice or stuck expansion valve.
