I purchased a JD 650 recently, which inspired me to sign-up at GTT,,,
My "other" tractor has been here for just over 20 years,,
This is not a common tractor in the USA, most (if not all) 584's sold in the US were 2WD, mine was brought to VA from Canada by the PO.
It will do most anything, as it is kinda heavy,,,
Several years ago, I went to the JD dealer to get a CUT and a 72" mower, they did not offer one.
They did have this setting in the yard, so it came home, instead;
So, as my usual method, I went cheap,, and never purchased a CUT,,,,
I get by with this as a field mower,,,
