Sources: 3 forum discussions about the John Deere 5045D and 5045E utility tractors; heavyequipmentforums.com and tractorbynet.com.

Missing at low rpm, dead hydraulics and crank-no-start. A 5045E that missed at low rpm and made white smoke after 20 minutes (a reply asked about the inline fuel filter under the tractor), a 10-year-old 5045D with 112 hours whose hydraulics stopped (a reply said to start with the filter and system pressure), and a 5045D that cranked but would not start after fuel filters were changed. Threads read: 1, 2, 3.
