Secure the shaft so it can't turn (pipe wrench on spacer), then tighten the nut on the shaft. When you think that you have the nut tightened enough, hit the discs with a hammer - if the discs don't ring, you need to keep tightening the nut until the discs do ring! There should be some kind of keeper on the nut to keep it from coming loose, but getting it good and tight is essential.

I thought holding the spacer with a pipe wrench only works for square bolts, not the round ones.
For round bolts I usually try to hold the bumper with a wrench and then tighten the nut; might take a 2nd person. Check it every few passes in the field until it won't tighten anymore. I take the wrenches out on the tractor with me. A good thick nut with more threads than a hardware store nut helps too.

As far as his disk having round bolt in square spacers, maybe bolts were replaced in the past.

I will add if they are loose enough that dirt has gotten between disc and spacer you will never be able to tighten it enough until its cleaned out.

Yup- dirt grit turns to powder and the discs are loose.
