I appreciate all the feed back guys ,we got this old disc for doing 4-5 acres of food plots ,we were gonna replace the smooth disc's with notched so thought why not try it if the plasma doesn't work we were gonna replace them anyways ,and thought use a template and use the plasma for quick cuts as to not heat up the metal ,I guess it's worth a try .

Well plan on doing all the work and then replacing the blades as they will be worthless to use after doing all the work. Might as well order the new blades befor starting to notch the old ones.

Heat is going to make them brittle. Most likely end up breaking
every one you cut.

Why would they get brittle? If anything it would anneal them, making the cut edges soft and they'll wear more quickly.
Brittleness could happen if they were heated and then quenched, but I doubt that's the plan.

I agree with the person below who said leave the blades alone and put more weight on the disk, a couple 100 lbs of wheel weights or the like.

Botched blades aren?t all that, what you want is deeper penetration weight will do that.

Another thing that for me has helped even more than weight, is use the longest top link you can find. The rear of my 3pt disc is barely off the ground when I pick it up, but it only takes me a couple passes to turn sod into dirt ready to plant. I have all smooth blades.

I have notched a lot of blades with a plasma cutter. I do it so they won't slide instead of for better cut. By using the plasma instead of a torch you don't get them hot so no problem with heat problems. Did it both on the leveler I built behind the soil saver plus a old BWA disc we pull behind the stalk cutter--re-sharpen as needed---Tee

Is that an 8960? Never dreamed notching your own blades would work

Sorry I did not see your post SV--I don't know if the notched blades would hold up on a heavy disc but for what we do it works for us--Like I said it is mostly to keep the gangs from sliding. It is a 8760 had a 7020-ST-250 and a Cougar 1000-then got the 8760--The wife runs it most of the time--She likes it--Stay Safe SV---Tee
