XT2 LT42 picks up a lot of debris and dust

I assume that the dealer would have leveled it

Never assume such things. I have yet to own a mower that was properly prepped before my taking delivery.

2 Each of either part number for the low lift blades.

Why do some blades have 2 holes on either side of the S shaped hole and other don't? Is that a feature of the high lift blades?

Don't assume anything!!

Make sure that the hinged Chute has a deflector pointing downward at its' end. Stop mowing over dirt.

Now Gord must know my neighbor that I can't see when they are mowing their dirty yard...That new mower isn't going to last long doing that.

Some blades use a stiffner plate to hold the blades and prevent them from self tightening
Others have a mounting boss so the centre bolt holds the boss on while the smaller bolts hold the blade on
Decks with timed blades use this system so that an out of time blade just breaks the smaller bolts and does not continually smash into the other blades.

The blades with two holes besides the center mounting point can be used for 21” or 22” push mowers. They are designed to fit on the blade adapter.
