Cutting edge, do a search on the net, you will find suppliers of hardened, abrasion resistant steel cutting edge stock. You will have to check hole spacing, and the width that would work best.
I would suggest researching the manufacturer, I've attached a link to the unit that appears to be similar or what you may have.
I saw those photos, where the previous owner, did not change or reverse the cutting edge, and that its worn down quite a bit. Regardless of previous comments, that could be built back up, weld in a piece, then get a replacement cutting edge from woods, they still make these, so you should be able to source a new cutting edge.
If you go to a highway dept and get used stock, they can't use, but can be re-purposed, it may just be a weld in, not the right size, holes don't match or the wear on the ends is excessive, etc. To me that may work, but its kind of a sloppy repair, and it voids the cutting edge to be replaced easily, reversed etc. which is what it came with originally, re-sale will be less when done like that, though you may not sell it for many many years, always worth considering.
For an implement such as this, a competent heavy equipment, steel fab shop welder etc. could repair that so its as strong as it was when new, likely by welding a piece in, then just replace the cutting edge if Woods has it, they list a specification of its size, 1/2" (.5) x 6", so if by chance they have it, that's all you need, if not, you'll need a section of same with correct hole spacing. I'm not sure of the hardening on these, how deep, it could be a tough job to drill, steel shop with a punch is usually how these are fabricated, or so I thought. I'm not sure if that can be done after hardening, so it could be an issue with a used or new piece with the wrong spacing, its common with mild steel, like A60, I used to buy quite a bit of steel with holes or slots punched out. Only other thing I can think of is a cutting torch, but that may entail embrittlement and with the square shoulder on the fasteners, bugle head, clipped, forget what you call those, you need a square hole, ie; steel shop with punch, going this route just makes more work and does not match how the implement was built. Plasma cutter, have no idea, just brain storming here LOL ! I'd have to suggest, get it welded up, get the right part from Woods, be done with it, and then that implement's value is restored because its done right.
We have a local guy who does work in industrial plants, factories, welds, fabricates, many years of experience, he'd have that job done in a day with all the materials on site.
Caterpillar does offer cutting edge stock that I know of, if you provide dimensions, just the length, relative to hole spacing is what you would want to match. Potentially, 1/2" x 6" double sided cutting edge, possibly 76" long or longer with correct spacing, if longer, cut the end or ends off to match what you need.
Many suppliers of this material are on the web as well.
Hopefully of some help !
