1. The video from Exmark mentions "optional anti-scalp wheels". Are these actually available and has anyone tried them? How are they attached? 2. Does the deck appear to have any sort of spring loading to lighten the effective weight of the deck? If it's got an engine on it I assume it's so heavy anti-scalps might just gouge the turf. 3. Anyone in the South cutting Bermuda or Zoysia lawns with the 48/52" models? I like to have the added protection of antiscalps like on the Turf Tracer HP/Lazers. I've only seen one lawn cut with a Grandstand, and wasn't impressed at all. It was a doozy of a lawn, erosion ruts on a steep hill, but the mower didn't handle it well, or maybe it was the operator. 4. How are the front weights attached? Bolted on? Is this optional or standard equipment? Thanks.
