    I was thinkin the other day about how we could make our meyer straight blade more efficient for backdragging and pictured the following: Mount a 12VDC electric actuator to base of the plow where it swivels and mounts to the a-frame and the other end to a pusharm welded to the plow frame/moldboard to allow the blade to pivot forward as it would to trip over an obstacle, thus causing the cutting edge to be vertical and better for scraping during backdragging.

    my biggest question is how much pressure do the trip springs exert when properly tensioned? i need to know this to see how much pressure the actuator has to exert to overcome them. the rest is pretty simple.

    so whatcha all think?

    For all that work ,it would be easier to put a Boss on it.

    Buy a Sno-Way that has "down pressure"

    How much down pressure does a snow way exert.

    Do you have a specific actuator in mind?

    idk yet, thats y i need to know the pressure of the springs.

    I guess i dont understand how it would be mounted, The actuator / cylinder would have to float when not in use, since the mold board still needs to trip.

    I do agree, if you could tip the blade forward an inch or 2, i bet it would backdrag a lot nicer.

    Not sure on the exact number but it will take all the weight off the front suspension.
    Won't lift the tires off the ground but it is enough to scrape to bare pavement.

    It wouldnt need to be bolted to both ends, it could float into like a recieving cup or whatever on one end, ill draw somethin up...

    Here, a 5 min rough draft of my idea, at the a frame, the unit pushes into and pivots in a cup like unit, if plow needs to trip, it simply lifts out of the cup and when it resets, returns into the cup.

    I would mount the cup on the plow and the actuator on the frame.. less mas to get thrown around and the actuator wont be slammed around when the blade trips.

    that was my original plan, but i would need to figure out how to reinforce it

    How do you intend to power the cylinder?

    electric actuator, this kinda thing, note that these arent necessarily going to be be the ones I use, but just to give yall an idea:

    From post #12 the idea will not work. All you will do is put stress between the king pin and the top of the blade. The actuator needs to sit between the A frame and the lifting bracket on the truck.

    Good idea!

    That would be correct if you are trying to use it as a down pressure system.

    His idea is to use it to tip the blade forward and inch or 2 so the cutting edge sits at 90 degrees to the ground.

    I was sorta thinking the same thing about a cup idea with the cup mounted on the board.

    I would think it would be better to mount the actuator on an angle vs. strait up.??

    I also think you would need a beefy actuator. All the pressure from back dragging, trip springs, ect, will be on the actuator itself and your mounting setup.
