Thanks for the follow-up sax. I still haven't figured out what's going on. I ran out on Friday (last) and picked up a quart of anti-gel and a new filter at the local Kubota dealer in PI. After I added the anti-gel I ran the machine and it seemed fine. Late morning Saturday I ran it again for about 1 -1.5 hours and by then I thought everything was jake. I had parked it outside overnight again which was probably a mistake. Sat afternoon I thought I'd go and pick up a few things at the grocery before the storm hit and tried to move the tractor and she wouldn't start at all... not even a cough. The fuel filter bowl looked frosty so I unscrewed it and found a lot of slushy fuel (looked like ice) I cleaned all the shush out and replaced the paper filter cartridge. As I was screwing the bowl and cartridge back on to (the fuel pump???) at a certain point a valve released and fuel filled the bowl. I tried starting it but again wasn't even getting a sputter out of it. Eventually I ran the battery down. My driveway is 1/4 mile long and with the storm coming Sunday, without the tractor to clear my way out I'd be in trouble. I decided to bag it. I'm not sure when I'll be able to get back in now with limited access. I think they got an additional 18" on Sunday/Monday. So right now I'm keeping an eye on the snow depth map.
