Cutting Edge

Discussion in 'Fisher Engineering Discussion' started by Ron G, Dec 20, 2007.

  1. I bought a brand new HD 8 foot MM2 in 2004, and it's on my 2003 F-250. Almost every Fisher plow I see on the road has a cutting edge. Mine did not come with one---Was it supposed to come with one, or was that an extra cost option ???

    They are optional, you can run it for quite a while before you put an edge on but I personally would do it from new.

    Quite possibly because you did not grind off any of the slag that had developed on the edge of your base angle due to use/wear. As a result, the cutting edge is not sitting completely flush against the base angle, causing a slight gap. This can cause either repeated bolt failures or the cutting edge itself to fracture.

    fisher supposedly recommends not having one on for the first season or first however many hours to break in the blade and moldboard???? not sure but that may be why it didnt come with one. i would put one on.

    all the dealers around here sell the plows with the cutting edges on them, I wonder if your dealer is taking them off and selling them separately?

    i was told you are supposed to wear the trip edge down a little before putting a cutting edge on, it makes it trip better

    You are supposed to wear down the base angle before installing the cutting edge.
    If you put a cutting edge on a new fisher plow you will not scrape at all down to bare pavement. I have run my 8.0 Fisher for 2 years without the cutting edge and the base angle is only slightly worn down.

    I am not 100% sure that the same applies to an X-Blade, but if it has a base angle like a conventional Fisher than I would wear it down for a season or two before installing a cutting edge. This also depends on how much snow plowing you do and how much snow we get:waving:

    If you put a cutting edge on a new base angle when the cutting edge wares to the base angle you will start waring both. This will do two things.

    1. I will not wear as fast because you now have more material on the pavement.
    2. I will not scrape as well because you have more material on the pavement.

    You should actually wear the base angle a lot before installing a cutting edge. Just don't go to far as to start getting into the trip spring brackets.

    haha funny you should mention the trip spring brackets. i was talking to a guy who plows a car dealer lot, and he says to me

    'i was plowing a couple storms ago and all of a sudden there was thing BANG and something just went flying out from the plow. i didnt know what it was so i kept goin. a short while later there was another BANG and something else came shooting out. now i says holy #$% what the hell was that?! well there was no cuttin edge on the plow and i had worn through the brackets for the springs. so it was the damn springs that was flyin everywhere.'

    luckily nothing hit any of the cars .and holy crap this guy plows??!!! first impression was total :eek: lol anyway he was a character
