That's the earlier version with two huge wheels mounted very close together at the rear and rear wheel steering. Later models have the tracks at the rear (also steerable) and what almost look like bicycle tyres up front with insane steering angle.
Living in Kent I often get the odd glimpse of farm plant but that's about it. I had a job in Sittingbourne and would often encounter JD vehicles from the nearby farm - usually a 7rT or bigger frame 6Rs. Best spot was an early(about 630am) convoy of easily 10 6Rs, all pulling high sided carts, with a forage harvester at the head.
Second best spot was a Claas Terra Trac harvester of some sort, with a Scorpion Telelift towing the header, causing all sorts of traffic problems in the back roads between Sittingbourne and Gillingham. I think I was the only person happy to see them. I do often see NH tractors on be back of trucks near Dartford. My g/f always sees something at the roundabout near ThanetEarth but I'm rarely down that far East.
Finally, I was supposed to have a tractor experience as a birthday present this year. About half an hour each in a modem 6R and a classic Case 1455XL - cancelled, obviously.
