Thanks for the feedback from across the pond! I'm trying to visualize the "imperfect" component of the conventional 3PH. I can see it if the front pivot point of the side stabilizers isn't in line with the front pivot of the lower arms.That's another characteristic of the specialized tractors for orchards and vineyards. It goes along with all the other stuff we discussed on another thread that got closed.
Some of them are so narrow, that there is absolutely no room for stabilizers. So they came up with that design. Some are like the ones you showed, with no side play. While other actually have hydraulic stabilizers incorporated in the rear end housing, a more expensive solution usually available on higher end tractors. As you mentioned, it also gives the ability to use Cat 1 or Cat 2 implements. Top and Tilt setups are also a common feature on these tractors.
European brands like Same, Deutz, Antonio Carraro, Lamborghini, etc, will offer models with this style of 3 pt hitch.
With that fixed design, there is no need to have side play because of the way the arms are built and come out of the tractor in a straight line. While on the common 3 pt setup, it needs side sway to accommodate for an imperfect linkage movement going up and down cause by the bent design of the arms.
Yes, I should I added that part. Usually the pivot point of the lift arms and the pivot of the stabilizers is not actually in line, so it can cause binding if the stabilizers are adjusted too tight and there is no side play.Thanks for the feedback from across the pond!

Absolutely. You can check this video. The 3 pt is covered at 1:30 mark. EDIT: Forgot the link:hydraulic stabilizers incorporated in the rear end housing
Would you happen to have any pics or links showing the hydraulic stabilizers? I've not seen this but its an interesting concept and the ability to control the lift links laterally with optional float capability would seem to have merit.
