Do the two blades need to be at right angles?

What is the manufacturer's recommendation: Do the blades need to be assembled at right angles to each other for the suction to work properly?

No they do not need to be.
Those blades are turning so fast you don't notice any difference one way or the other.

Thanks for your reply.

I don't mean to be annoying here, but can you double check with the engineers there?

Here is the science teacher coming out in me.... the blades are providing suction, right? Well, so do box fans. And, if you set up two fans, one behind the other, facing the same way, they fail to help each other move air. Instead, their corkscrew-shaped tunnels of air clash. I was hoping that that was the reason my Hustler was giving a very odd cut recently (the grass on the outer edges of the path are not getting cut very low). The blades may be disturbing each other at that positioning.

I haven't had a chance to readjust the blades yet, I will let you know the outcome when I do. Everything seems fine with the deck and blades, but the cut is off, who knows......

In theory you are correct, I have had this same discussion many times with our engineers, it's been brought up here on LS a few times as well.
In a perfect world they would actually stay in the position you put them in, but in this application they will not stay lined up for very long.
Also think of how fast they are spinning and the turbulence it creates.
