This may sound dumb, but I replace my fuel filter on my 1025R.
The tractor was always started easy and ran well.
When I replace the fuel filter I turn the key and let the fuel fill up the filter and the glow plug went out. The tractor started and stalled. Then I restarted it and it ran just like it always did, fine.
Now hear the problem. Every time I start the tractor it starts and stalls and runs well on the second start.
I can't see were I or what I did wrong on replacing the fuel filter. I only use John Deere parts.
The tractor is one year old and 100 hours. It was just a maintained I do on all my vehicles every year.
