Alright, so maybe I'm an idiot... but for the life of me I can't seem to figure out the "logic" behind the naming conventions for scag walkbehind mowers. SWZ - Fixed Deck & Hydro SW - Fixed Deck & Belt SFW - Floating Deck & Belt One other, with a "U" or an "X" in there someplace I believe, floating deck with hydro. Heard scag discontinued that line. It's not a big deal, but other than the "W" for "Walk", I just can't fathom the intent of the other letters. Is someone knows, please tell me so I can have one of those "Oh yeah, of course... why didn't I see that" moments.
