    I have a Fisher LD plow . It came with the poly cutting edge . The edge needs to be replaced so I bought a steel 3/8" from the Fisher dealer . The dealer told me to install the steel edge right over the old poly edge. I never saw a double cutting edge so I removed the poly and installed the new steel edge. When I began to plow the plow and truck ( 2005 Yukon ) shook violently. I don't know why. I removed the new steel edge and put the old worn poly edge back on. Question do I really have to leave the old poly blade on with the new steel edge or should I just buy a new poly edge . New poly edge $345 new 3/8 steel edge $122 . I would appreciate and suggestions or help . I have plowed with this truck for almost 10 years with this plow and had no problems . Thank you very much .

    Need to wear in the new edge just go easy for while it will get worn a bit. and stop shaking the truck violently.

    I run poly edges, new one will chatter also. Both will stop after they are broken in. Go slower - change angle.
    You may hear to drive down the road fast and drop the plow. I would not recommend this unless you are 100% positive there is nothing going to hook the plow.

    Thanks for the help

    I did ask the dealer if I drove down a bare asphalt road if it would help break in the new blade .He thought it might help. I asked him how many miles it would take but he didn't know. I will try your suggestions . Thank you very much for your help its very much appreciated .

    Yes do this on a smooth paved road. Get up to speed slowly lower blade so it is just scraping, won't take long at all. Very common concern.

    It's common with a new edge. Just think, a worn edge is basically a 3/4" flat surface rubbing on the road that bridges gaps,cracks,joints etc. a new edge has a 90 degree corner that is trying to dig into every little bump or imperfection in the road.

    Basically your putting all the weight of the plow on a 1/16" wide area instead of a 3/4" area

    Keep your plow angled and it'll cut down on the chatter. Won't take long for it to wear in
