Need a basic loader tractor and have come across a decent looking 1993 JD 6400. I've owned a JD6410 (without loader) for about 8 years a few years back, that I traded on a bigger tractor...so I generally know what I'm getting with the 6xxx series. Since 1993 was the first year for the 6400, were there any known issues that should concern me?

TIA
