You can set the disks where they just barely cut by changing the angle they are set too. Most disk I have seen any way and I'm 79.
79 here too.
My disk are pretty well rusted into one position. Probably been that way for 50 years.I traded a mule for them at least 30 years ago.I will give it a try though.
I knew what you were saying.
Need to get that dead stuff out of there somehow. You will want seed/soil contact.
I was afraid you would say that.
Looks like discing is all I can do.
