V-plow back dragging blade?

[Yardworks]

Does anyone have back dragging kit on a Boss V-plow? Do they make one? I'm not sure how it would work, because blade is never totally straight? Any thoughts or answers would be appreciated.

I have a new Boss 9.2 V with locking cylinders. Works fine.
Also I have a fisher ezv, which also back drags okay.
