We dont have hay wagons like you where wheels pivots around kingpins like a truck axle. We have rigid front axles mounted under a turn table, or slew bearing, like excavators have. Both in heavy duty road transport, farm transport and light duty commercial transport.
We only use kingpin steered axles on trailers with rigid drawbars. Only in on-road transport, tires are small enough to allow room for turntable steering on semitrailer axles.
On trailers with hinged drawbars that dont carry weight, kingpin steered systems have way too many hinge points that get sloppy real fast which ends up in a trailer swerving all over the road. Plus you cannot rotate them 180 degrees so its hard to back them in front of a loading dock.

Interesting. Other than specialty stuff (e.g. moving houses), I can't recall ever seeing any wagon with a steerable front axle used in on-road applications, around here. The trailers with axles only at the rear are called "semi-trailers" here, the word "semi" implying "half", with the other half of the load carried by the tractor. These are almost all you will see on US highways, in terms of commercial trucking.We dont have hay wagons like you where wheels pivots around kingpins like a truck axle.

As to hay and farm wagons with steerable front axles, the type with steering knuckles at either end of a fixed axle are most popular around here, today. The type with a moveable front axle on a single center pivot have been around forever, but seem to be less favored, today.
Of course, this is a big country with varied terrain and history. Someone from the Great Plains states may say all my statements are backwards, as mine are based on watching those working in hilly terrain.

My Dad made a hay wagon out of a 50's Oldsmobile chassis. When hooked to the baler and loading the wagon, with its
springs it felt like you were on a boat. It worked fine until we quit farming.

You cant do that with knuckle steering without bending the drawbar...
Next to dumpster draw-up systems we have the BDF system in Europe: you park the cargo box on high legs by airing up the air suspension, setting up the legs, and airing down to drop the chassis. It allows to combine loads for different locations without a warehouse facility to transfer cargo, you just swap BDF bodies. You can do that at a highway parking, anywhere.
When i was in Canada in 2004 i found that most Canadian truckers could only drive forward, like Eastern European truckers. You wont get a license in Western Europe if you cant back up a semi in front of a loading dock with 2 feet on each side to spare.. but guys driving combinations, thats something else, theres a special driving license category for combinations...
Jack knifing like in the previous post is routine in the bulk tipper industry. These days most trucks are fitted with "feelers" that detect the drawbar and set off an alarm so you don't bend the drawbar.
The poor quality video means you can't see if it is fitted with feelers or not.
