I liked the way the 4020 drove but really didn't like the way it operated overall. The levers on the early ones were all in the wrong places. I never got to run a side console. The trans was a pain on a square baler if the windrows were uneven. 3 pt capacity was also pretty bad as hauling one decent sized round bale made it light on the front end. And yeah, the motors etc. really didn't hold up so good. There were a lot more overhauled every 3000 hours than weren't. I was always happy to get off of it, and go climb on one of our 966's, even prefered the 460 to square bale hay. Overall, our 7120 is the nicest tractor to operate I've ever been in very many hours. Everythings where it ought to be, shifts good, steers good, brakes good. Really nice tractor. My 5140 is super too, but I suppose that oughta be for another thread.
