I found my multimeter and the battery was absolutely GONE. I found the date on it to be from 2006. I put a new battery in and everything is fine. WoooHOOOO! Well, I better settle down because, well, knock on wood...
Thanks for the replies, and for putting up with my crabbiness. I was seriously about to buy a much newer and more expensive Kubota but I've decided to listen to everybody and give this tractor another shot and see if she can't provide me with some good service. I've addressed everything at this point aside from cosmetic stuff. New tires, radiator, hoses, fluids, starter solenoid, battery cables, battery, and temperature gauge (still need to mount it). And, I just bought a 5' Land Pride rake. I'm going to use her and see how things go. If she breaks down then I will fix her again.
