Whoa…I went to ask about float and totally forgot I already had!! 
On our old 2001 model, I “accidentally” discovered the float feature, and started using it. (Any markings were worn away) It worked amazingly well, other than I had to start holding the stick in position. I don’t know why this new one acts much different—like you guys have said…it wants to drop and get run up on.
My main use for it is to lightly dig/smooth going forward. Maybe…it has something to do with the bar-tread tires? They’re a lot more “mushy” or “wiggly” so the unit doesn’t ride as smooth as our old unit with the turf tires…
