Thanks for the suggestion Tommy, but I don't have the $1400 to $2000 right now. And, as I've heard and learned, I can't become a successful farmer unless I learn how to do the majority of repairs myself.
And thanks for the response Rich. I'll definitely use the digital camera (great suggestion!). I've seen a couple of ways to keep the two tractor halves lined up and a way to roll one away and then back.
I have found a reliable mobile tractor mechanic who I've come to trust. I could always pay him for his time if I need someone to come out to the farm if I get stuck on something.
