2 piece snowblower deflectors

Does anyone here, by chance have a snowblower with a two piece deflector. Similar to what's on the Yamaha YS928J. I want to put one my Ariens. I have the two deflectors made already. So what I really could use are a few close up photos of the linkage/arms that tie both deflectors together. That allows them to move in tandem. I have found other photos of the Yamaha's set up but none that give me a real good look at the arms. I could probably work out the pivot points on my own. But a few photos would sure cut down on time involved in the trial and error method.

Plus each change of direction means the stream of snow loses more momentum crashing into itself at the point of change. So is it better to have 1 or two big changes in direction or 3 or 4 smaller changes???
It's better not to have any chutes at all. On some huge airport snowblowers, the chute moves out of the way so the snow comes directly out of the impeller without any friction for maximum throughput. But I think if the snow is going to make contact with the chutes, it's best to create a smooth and gradual change in direction.

I have the Husqvarna 12527HV which has a chute like this:  I sort of agree though, I don't understand why 2 piece shoot is necessary and on the fancier Husqvarna models its all 1 piece. |

This discussion brings up a thought for driving the evolution of snowblowers... Wouldn't it be more efficient to place the chute opening on a rotating collar around the impeller? Need to blow to the right? Rotate collar to the right. Need to blow to the left? Rotate collar to the left. In many cases, you wouldn't need a deflector at all. The deflector would only be used to direct snow forward/backward of the blower when the need arose. Maybe I'm overthinking things... I believe that some of the old Gravely snowblowers had rotating
impeller housings.
