Thanks, I can now see there are no outside anti-scalp wheels for the sides of the deck, you can get one, two, or three, which are all located in the center. These are all wheels according to the picture, no roller that I saw, is this what you saw as well? I consider a roller to be longer than a normal anti-scalp wheel.
I am enclosing the three part video series, some may have seen these, but a few such as myself may not.
