Other than yesterday's tractors, can you recommend any other parts website that might have hard to get parts? I can get most parts from yesterday's tractors, but those 2 parts I can't find anywhere. Everything you've read about the problems I'm having, do you think it would be worth checking out the unloader valve? I've just heard it's extremely hard to get to. I did want to clean the hydraulic sump and system, from what I've read i can pour a few gallons of diesel in the sump and let it cycle through the system. I just didn't want to damage anything and make sure i get all the diesel out. Which after I've drained my hydraulics, i still have some in the bottom of the sump, and other than wiping it up with a towel, wasn't real sure how to get it ALL out. Thanks for the reply BTW, I really appreciate it. I didn't realize how dependant I am on my tractor working until this week, so I'm doing my best to fix it. Does it sound like I'm on the right track?
