But then what makes it work after an hour of running? After that 1st hour can you run the tractor all day with no issues? Interesting problem, I wish I could be of more help.I just thought that if the turbo was not functioning properly that would explain the loss of power.
I think it would be a blessing in disguise if it did it all the time. If that is the case you'll be able to zero in on the problem. I would double check that fuel leak fix and replace the filters. Cheap and easy to start with. Could be the fuel pump too.I just bought this tractor about 2 weeks ago. It had a small fuel leak after the lift pump that I fixed, the previous owner replaced the lift pump and changed fuel filters. I may change the fuel filters again. I'm now thinking that it might have been coincidental that it started working after an hour. I ran it for about 2 hours the other night and it never seemed to gain the power.
