Broken Cutting Edge

    Not sure how to move a thread, I posted this in the Curtis forum and am pretty sure it should be here.

    I broke my cutting edge the other night. When I talked to the shop I use they offered to give me a 1/2" thick edge. The Curtis edge is 3/8" thick. Should I replace it to match the original 3/8" edge or go with the 1/2"? Are there any cons to going to the 1/2"?

    It isn't from Curtis, the fabrication shop makes them. I bring in the old one and they will line up and punch out the holes. Total cost, $80

    I was told that steel soft enough to punch wasn't worth putting on as cutting edge.

    if it is 1084 steel it has to be drilled w/ special bits (usually in a mill) and then all you're punching out are the corners.

    So what do I ask to know the steel they are using is strong enough, if it is 1084?

    go with a 7inch wide by 1/2inch thick piece of T1 steel (bulldozer steel).. if your blade is a 7.5 the edge will weigh 90lbs.... i just bought and did this to my 7.5 snopro 3000... and btw, save yourself some money and dont have them punch the holes... tourch them out yourself.... take off the old blade, vice gripe the new blade up at the 3.5 inch (middle) take your curtis touch up paint can and spray where the holes are... take it off, and tourch the new holes, and grind clean... replace with all new grade 8 hardware.... you can flip the blade to use the upper portion when the lower portion is ground down.....do this, believe me... i found out the hard way the first time when i sent my local steel yard my old cutting edge to use as a template.. they measured, and boy they got it WRONG!! everyone knows that a template is used to lay over or 'mirror' the other.. not those guys:laughing:

    Whatever you do make sure you go with the 1/2. They use the 3/8 to save on #. You will not chip off the 1/2 if you do you will be picking up pieces of your truck, cause whatever you hit will def. F your truck up...

    Looks like you were due for a new edge anyway. There is no disadvantage with a thicker edge. But the 1/2 inch ones can break and bend also. I have done it.

    Well, the steel from the fab shop is not as strong as the original edge. To upgrade, material alone is $175. My local Curtis dealer has the factory edge in stock and claims it is T1 for $130. It seems to me I will be better off with 3/8 T1 than 1/2 inch hot rolled.

    Hot rolled won't last at all. You have to go with cutting edges. 5/8" are also available and we usually get a couple seasons running them with feet on the fishers.

    I doubt it is T1. Couldn't punch it.
    1084 or maybe 1090 material. 1084 is what we have our blades made out of.
    @ 130 does that include bolts?
    could do a 1/2" x 6" for that amount and include bolts

    The holes are punched before the metal is hardened. Lots of T 1 edges out there. I have them on my Blizzard from factory.

    I emailed Curtis and they said their cutting edge is 1080.

    You could ask your local highway dept. where they buy their edges. I can buy widder and thicker edges if I want at some municipal supplies that sell to the cities and towns in NH,sometimes the prices are pretty good. We can also buy carbides for the graders,trucks but they are expensive. The holes come square so the bolts won't spin when you tighten the nuts. We have bought plow bolts from fastenal if we couldn't get them at the municipal supply.I beleive the bolts are carbon steel. plowking
