Good day.
I am not sure if this will help or not…
I’ve never measured the angle on mine, but here is a couple pics if you like to try to guesstimate it….depending on what you are wanting to do (height / width) you may need a different setup.
I just recently added a second set of discs, but I did not change the angle. IMO take your crescent wrenches / socket wrenches with you when you go to the field, after you go a little ways, you’ll see soon enough if you need to adjust them. I’d probably start about 45 degrees and go from there. It may take a few adjustments to suit yourself.
I think I have spent more time monkeying with the cultivators to get that height / depth set right compared to the discs…my cultivators are right in the tracks so it’s compacted by the tire and need to be set just a bit lower than the discs for my set up. Personally I’d leave the cultivators up until you get the discs set where you want them and then adjust the cultivators down from there. YMMV.
Good luck and have fun.
