Hey all, I have an SMC loader with a 72" bucket on it that needs the cutting edge replaced. The previous owner put a piece of grader edge on it that is curved. With the rounded side down it's impossible to scrape withe the bucket level to the ground. My question is does anyone know what the typical dimensions are for a cutting edge on a 72" bucket would be? I have a few steel places around that handle flat stock of various sizes. I was thinking maybe 7/16" x 6" ? I don't want to over do it so as to not be able to add a tooth bar. Also how much overhang should there be on the front exposed/ leading edge? By the way this is a weld on edge.

I bought a piece of cutting edge from Discount steel that was 5 ft long by 4 in wide for around $35.00 plus shipping.

Did you have to taper the front edge, or was it pre-cut?

Also does anyone know what size cutting edge is compatible with the Markham tooth bars? In the future I'll probably order one of their tooth bars, and would rather not have to replace the cutting edge again just to make it fit.

P.S. I checked out Discount Steel, and their price for a hot rolled cutting edge doesn't seem too bad, but I bet the shipping is a killer!!

IMHO

I'd stay with the grader cutting blade due to the quality of steel, if you get the right style of replacement high carbon blade you could always get some bolt on bucket teeth and that would provide you with the best of both worlds when it comes to being able to use your present bucket.

What I got was a hot rolled cutting edge.

I replaced the cutting edges on my clam bucket. Because it opens it has three. Mine was welded and I used the torch to cut it loose and the port-a-power to straighten everything out and welded in new cutting edges,

My machine does a lot of concrete removal and it is rough on the bucket. The new edges are thicker then the original and are holding up well after two years. I also ran hard face in a pattern on the wear ares on the bucket.

A bucket cutting edge should be high carbon or tool steel. The grader blade idea is ok if prepped properly. The edges should stick out about an inch on each side to allow for wear and keep the side cutters off a wall surface if cutting that close. A soft steel cutting edge will wear out fast and bend the first time you put a strain on it. That's 40 years in heavy construction advice. Use it to your discretion. PJ

Well. . . Today I got a new cutting edge. It is a bolt on reverseable style that is slightly longer than I need, but that's not a problem. And the really good part is it was FREE!!!! Seems that a local company was making skid steer buckets, and had some left over cutting edges. I just happened to be talking to the right guy at the right time today. They are the high quality steel that is designed to wear better than the hot rolled steel.

Way to go! You can't beat a deal like that with a stick!
