That stuff is pricey--I just got off a couple of websites looked at 3.5" OD and 4" OD x 3.5" ID to nest. I thought it'd be neat to permanently make the "shell" with its holes welded to a Clevis Hitch plate and then have the different implements "plug in" to the shell like a tongue with matching holes for the different rotation angles. No tools changes, just a pin and hairpin clip. Guess you'd only need 10" for the hitch and 9" for each implement, assuming you had the rest of the arms, backing plates, etc. My son, who also thinks your idea is very cool, suggested it'd even handle a single-tooth ripper (we're gonna be dealing with some sapling roots). IMO and machinist experiences ,if you used 1/4" wall DOM tubing 2.5" OD and matching ID same wall, (beefier than race car frames/cages) it will be more than adequate as most of this Brinly/AgriFab stuff is barely 1/8" (my 2x3 rectangle is 1/8" wall) and will allow better fitment/weldment to the existing clevis... If you look a Brinly 42" rear blade you will see where the clevis bolts to the square tube main drawbar that's where I would get my actual pipe dimensions from and assemble from there. Commission not needed unless we are patenting this thing ... Plus you buy the plain clevis here https://www.ebay.com/itm/224230909169.
