Has anyone had a 2004 D45 that has been hard to start? The tractor only had 400 hrs on it. I changed to fuel filter which was pretty dirty and thought that might do it but still does the same thing. After running it for awhile it turns over but will not fire up. A couple of cranks later and then it starts right up. Seems like a fuel problem but would have thought the filter would have cleared that up. Thanks in advance to those who reply.
