Poly Edge - Problem: Making Waves!

    Sno-Way Mega Blade 8.5' w/ 9" wings

    A major client of ours required that we change out the steel edge for a poly edge so not to "void the warranty" on their recent seal-coat job.
    We bought a polar edge from Lacal. We don't get much snow, so the edge has about 15 hours on it.
    When things thawed out and we were cleaning up, we noticed the edge is wavy all across the blade. Low spots at bolt holes and it cups up in between the bolt holes. That has us really mixed up.
    The Sno-Way does have hydraulic down pressure and it was used off and on during the plowing.
    Has anyone else experienced this? Any ideas what is causing this, how to remedy this or prevent it?

    When you put the polar edge on did you use the steel edge on the out side of the polar? We always put the steel back on flipped so the edge that was on the pavement is now facing up, this will hold the polar edge flat on the moldboard, sort of like a back up.

    Poly Edge Problem

    Thank you for your replies.

    Yes, we have a metal retaining strip bolted down the the front of the cutting edge. We can take that off and put the metal edge on. Would that make a difference?

    Yes, I believe we installed it correctly. It is 1.5" thick and we mounted it with 1.5" leading edge from the back of the mold board.

    Is is possible that the back-dragging needs to be done on a warmer day? We did that but after sub-freezing temps set in.

    Thanks for your help!

    It depends on how heavy (thick) the "metal retaining strip" is, If its not like the cutting edge I would put the old edge back on.
