    I have called 2 dealers... Both are unsure. Will a steel cutting edge from a 7 1/2 HD plow fit on my 7 1/2 LD plow without modifying the bolt hole pattern or doing any fabrication? Thanks in advance.

    I don't believe fisher has ever changed the bolt pattern of a 7 1/2 cutting edge. I bought a cutting edge for an old 7.5 this year and it was the same as the new one.

    Best thing to do is measure you're bolt patter and ask the dealer to measure when you purchase.

    Yes it will, i think the only thing you have to do is the plastic cutting edge has to be left on.

    Thanks for the replies. I found a parts schematic for the LD online. The part number for the 7 1/2" cutting edge is the same part for all 7 1/2" plows, so I picked it up today.

    did you put steel over the poly or just the steel?

    The poly edge sucks...leaves a base...why do you have to leave the poly one on when you put the steel one on?

    No need to leave the poly edge on.

    Excuse my ignorance here, but what is the advantage to a steel edge over the standard poly that's on the SD/LD series? I've had 2 of these plows so far and wonder if the performance of the plow might improve with a steel edge.

    Thanks

    Took my poly off and installed a new steel edge for the last couple of storms this year. All i can say is WOW, scrapes clean and leaves no base now, wish i would have change it in the beginning of the year......

    All Fisher 7.5' plows use the sme bolt pattern and it is the same bolt pattern as Meyer so buy whichever edge is cheaper.

    I thought the same thing.....but the meyer was off about 1/8" when I tried to bolt it up.

    Rare but use a ream to aline the holes. that will fix you right up.
