Brin, your problem may be in the ignition switch like mine was. No guarantees but I had the similar problem on a different tractor, a 1700. Also read the post below. Here is a link in case it moves. http://www.tractorbynet.com/forums/new-holland-owning-operating/288801-tc-40d-starter-problems.html I think a lot of starting problems are really ignition switch problems. I am not a mechanic, just an old try to do my own work guy.
