NEW Blizzard vs Old Blizzard Model???

    I just found out this week from Blizzard that the old Blizzard 810 model used hydrolic rams to extend and retract the wings forward.

    But then they changed the new ones to springs.
    Does anyone have the old version?
    Can you change the springs on the new version to hyd rams?

    If I understand right, you can backdrag with the old version, but you cannot backdrag with the new version because the springs will not hold the wings straight.

    I don't backdrag with the wings out.How much backblading do you have to do where it would make a difference?

    This may be a stupid question, but here goes. How can a spring make something extend and retract when the spring is in the same position?

    The spring on the newer 810s is just to return the wing to the zero degree position. The cylinders in the moulboard power the wings in and out. You can still back blade with them. its just going to pull forward in very heavy snow. Just like a Boss V plow does, but not as easy as the V plows.

    The Boss SmartLock cylinders eliminate the forward-floating problem on a V that regular cylinders may occasionally allow.

    I also am wondering how a single spring can exert force in both directions. Nevermind, I just re-read Mark's post and understand what's going on there.

    I knew the answer because our 8611 has 2 large cylinders that push the wings out. The springs are to help with retraction.

    Intlco if I'm reading right your saying the newest model is only using springs to move the wings in and out, that couldn't work. On the early model 810's I believe they had two hydro cylinders, on the newer models blizzard went to one larger cylinder. The cylinders are power in and out unlike most plow angle cylinders which are single action cylinders. The Blizzard at the scoop position has the pressure from the hyro cylinder holding the wing in place, at the full straight blade extended position the wings don;t have as much pressure to hold them in position as far as moving forward and back. So Blizzard put a spring to keep tension on the wing at its pivot point at the full straight position. The problem I and a few others have had is the spring broke, a quick warranty fix by my dealer. Blizzard either did used to at one time use 2 springs or wanted to use two springs as each wing setup has the holes and hooks in place. So I and a few others added the second spring in its allotted space, now each wing has 2 springs each wing. This is very helpful when back dragging at full straight extension as the wing has alot less tendency to want to fold forward. An additional plus in my book is the double spring setup now has 2 springs doing the former job of one alot less pressure is exerted on any one spring with 2 springs. I hope this answers your question.
