How has the John Deere 1023E held up over 6 years and 500 hours?

A private owner's six-year, 500-hour ownership report on the 1023E, notable for including actual oil analysis lab results with metals-per-million data. It covers real issues encountered, battery corrosion, a leaky axle seal, worn tires, ergonomics, plus the range of implements used. Depth is light and conversational rather than technical, but the long-term reliability angle and lab data make it useful for buyers cross-shopping the 1023E and 1025R.
