The UPS dollies have a locking pin set-up that makes it much easier when

Aha! The cheat is revealed.

As a kid on the farm I got hung up going around a corner with a
hay-wagon behind the baler behind the tractor and I had to back the
rig off the post and back into the bush lane so I could take another,
wider crack at it. No fun - particularly with the baler not following
in the same track as the tractor (offset to one side)

I'd be willing to bet that the balers didn't like backing up too much,
either.
