As there was few threads little time ago about wagon and drags and what benefits they have against artic Little summary for those who didn’t read those threads is that wagon & drag is generally much more flexible than artic. I thought to put few pics here showing those in benefits in “action”.
Most of these pics are about collecting eggs from farms, so usually you can’t wait for better weather nor choose better roads. And you can’t count on that there is sand thrown on ice… ■■■■ farmers. You have to get tail lift quite close to door so you can pull “roller cage” (?) on it. Something below 70cm from door is fine.
Blind side reverse, almost 180 degrees ( road ends “behind you” ). With artic you wouldn’t have any clue how close trailer really is from wall.
In this picture you see what I mean’t that you have to be quite near of door. This place is whitin limits of short artic. In summer there’s no problem but at winter problems would come from quite long slope which you have to reverse up. After getting here problems would come from too short trailer, all of the eggs wouldn’t fit in there.
You could drive here with artic but you couldn’t drive off from yard without some major forest work. There is also little possibility to get stuck here with artic… 
After previous picture I took trailer behind me and drove about 200km without seeing a single snow plougher 
That 15cm of snow didn’t slow me down but that road is one of finnish main roads so you could expect it to be in little better condition. I hope that I didn’t cause any dangerous situations as my rear lights were covered with 15cm of thick snow 
Windscreen wipers tend to freeze so I had to keep them up on the screen and temperature turned to max heat & blow. I felt like beeing in sauna.
This in UK after few years? Not typical combination but not very rare either. Basically this and normal artic need same space when turning as first trailer has such big rear overhang. Reversing is basically same as A-frame trailer, but much more difficult becouse you can’t follow with tractor fast enough. If mid-axle begins going to wrong direction you have to pull forward.
