I never realized why when talking about Back-Draging the wings on the boss would fold to the v position. Always thought these plows used double acting cylinders. I guess Boss just uses single acting cyinders that have spring presure on them for retracting back(is that so). This just makes what I thought to be some compicated hydrolic plumbing a whole lot simpler. If this is how the wings operate then Boss should have that locking cylinder option included in there set up. I personally thing $500 is a little steep for this option when you already have cylinders to start with. How does western move it's wings on the MVP are the cylinders singe or double acting also do their wings lock for back-draging or do they also sell a locking product? I know I ask lots of questions but this Forum is great for getting the real facts.
