    I have had my trip edge stick back and stay there 3 times this year after hitting some soft dirt. I greased the pins, but it still sticks open(back). I have to use a large hammer to pound the three spring posts to get it to close. The plow was painted this fall and I thought maybe that was it? But I thought all that spring tension should over come that. Springs are not broken.
    Any ideas from the experts?
    Thanks

    Maybe got a small stone stuck somewhere where you cant see it.

    I remember seeing a guy's Minute Mount's trip edge stuck open about two centimeters just from the driveways he plowed. Mostly beat up driveways and seventeen of them. I was shocked because I've never seen it happen before. I've had a 2x4 stuck in a trip edge before though.

    Actually sounds like a weak spring problem. While they may not be broke they may have gone into coil bind too many times. Do some of the coils look bigger around than others or stepped off to the side of the next one. They should be one above another:

    You could have bent something along the blade or edge that is binding the edge up when it gets tripped. I would try and watch the trip edge while someone drives the truck into something to trip it. See if you see any unusual bending or binding.

    From what you have described, I am 90% sure that this is your problem. And be prepared to pay big bucks if it is. I know its over $400.00 to replace the trip bar for my mm1. if you have some time on your hands(I know I do with snow totaling 0.0'') I would try and take all the springs off and see if you can pivot the edge by hand from all the way forward to all the way back. i'm sure that you will find that the bar binds and doesn't move like a hinge should. At least then you'll know what your problem is.

    Thanks for all the ideas. I will do a tear down and see if something is bent in the trip edge/pins.
    Thanks again.
