Is attack angle important?

Once you get it set right, you should be good for awhile.
How would the factory know how your plow is mounted on your truck? Setting the angle of attack is on the installer.

You should be able to find info online.
The manufacturer usually has recommended angle which you can find on their website somewhere.

Here is the answer I gave someone else, somewhere else when he asked about the attack angle on an HDX

"In the case of the HDX that you link to, the entire moldboard (and cutting edge) angle changes. As the cutting edge becomes more vertical, the top of the blade tilts more forward.

A more "aggressive" attack angle scrapes harder and cleaner but results in more rattling, vibration, and wear on the edge. Less aggressive won't clean as well but gives smoother operation.

On the older models, the stainless steel XBlade had the more aggressive attack angle which wasn't adjustable. Some people purchased it because they wanted the SS which wasn't available on the HD plow but then they were unhappy with the cons of the attack angle. The redesigned HDX gives you the best of both worlds by allowing you to buy the SS while not forcing you to use the more aggressive attack angle."

Do people really adjust it or do they just either use the factory setting or set it and forget it?
You didn't mention it here, but the attack angle is not normally adjustable except on the HDX plow you had asked about. Otherwise, the only way to adjust the attack angle is to screw up the a-frame and not have it sit level, as @Hydromaster said. (He must not have been part of that other discussion, so maybe that's why he wasn't aware of it....)

And I don't think anyone ever adjusts it. Ever.

On this “plow” the angle is controlled by the operator hydraulically.
roll the blade back( top edge towards the back) = less aggressive cut
Rolling it forward ( top edge forward)
= a more aggressive cut

You can actually dig in , go deeper and get more snow in your blade just by rolling it forward and not lowering it at all.

Looking at the picture the whit arrow points to the angle 55 degrees in reference to the back vertical line on right hand side. So looks like the drop a straight line down from top of trip edge and then trip edge is 55 degrees from that.
