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.
