JD 5045D

It’s not an old tractor but thought someone might be able to give some advice. I have a JD 5045D. I have noticed recently the rpm seems to be erratic. I can be pulling a disk and for no reason the rpm will jump up 300rpm or more. Once it increases it will stay at the higher rpm even if I lift the disk out of the ground. It doesn’t seem like it is the governor responding to an increase load. I don’t know where to begin trying to figure this out. Any help is appreciated.

Sounds like a problem with the throttle linkage or the injection pump. Have the fuel and air filters been replaced. Get ahold of the factory shop manual and read your owners manual about overall service before you feel the need to start spending money on parts.

Thanks for the response. I have been diligent about servicing the the tractor with air/fuel/hyd/engine oil filters changed regularly as scheduled and sometimes ahead of schedule. I’m leaning toward the injection pump, which is above my pay grade. I was looking for other opinions before talking to the shop about it. Thanks again

It’s been a while since I started this. Don’t use the tractor much but the problem didn’t go away only got worse. Finally figured out the strainer inside the fuel tank at fuel outlet was plugged. Looks like bacteria or algae of some sort. Cleaned strainer and reinstalled. Runs great now. Also started using Bio Kleen in the fuel tank. Hope this helps someone else that has a similar issue.
Thanks.
