UPDATE
Got the new tractor last night, they ran it in about 6 hours (no fuel left in gas tank though

) and they said they had no problems.
took it out today on 2 big jobs and one smaller one. (with the TN so when the TC broke I wouldn't be totally hosed)
NOTHING BROKE
It's a new world record
3 jobs in a row with nothing on a TC45 breaking.
Personally, I'm excited, hopefully it will continue to work.
Just in case you think all my bad luck is gone, I ate a nail in the front tire, but that's reasonably cheap. (although it's a loaded tire, so I'll have to go to the tractor place, they must have switched the tires on the two TC's, cuz my old one was loaded, they normally aren't).
I might have actually come out in the positive this week.
woohoo.
