Overview
An owner who runs both machines on his farm does a side-by-side walkthrough of a 2010 John Deere 4720 and a 2020 4066R, cataloging a decade of changes: hitch assist, battery relocation, entry steps and grab handles, loader numbers, exhaust routing, and cab ergonomics. He's candid that the two are remarkably similar overall. Best for current 4-series owners or shoppers weighing a newer model against an older one.
