Looking for help.
2 weeks ago I was doing some brush hogging and notice about a half hour into it that the rpm’s would drop from wide open 2500 to 21-2200 once the engine reached full operating temp. Thinking it was water in fuel I drained the petcock nothing out of the ordinary.
Yesterday I started mowing a hay field yet again 30 minutes or so passed by same symptoms drained fuel filter worked fine for a pass then fell back down to a constant 2100 rpm’s no hesitation or unusual sounds injectors etc.
This morning I places a new fuel filter on it ran great till it hit operating temp for about 30 minutes again.
After talking with John Deere I drained a full tank of fuel in search of a filter inside of tank no filter was present. There is no inline metal pre filter before the secondary with the water drain petcock.
As you can guess Im having issues priming it currently read manual know procedure going to add compressed air with a rag around it in fuel tank to speed up process tomorrow..Other than the small check valve being plugged what could be the issue with the rpm loss and lack of power. I apologize for the long explanation but I can’t seam to find help anywhere.
