I see there's an AC AD 4 grader 3 cyl Detroit, at auction next Wed, 01/26/22 on Auction Time. It's at Columbus, Nebr. 
I'd like to have 1, but have too many irons in the fire already.

I just wrote what the add said. I've not seen the machine only picture. 
I've thought the little 6 wheel grader with 7:50 or 8:25x20" tires and the 226 gas would be nice useful toy at my place.

I had a BD-3 one time. it had the 3-71 in it. kinda a mid sized grader. Then got the Fourty-Five. 516 motor it, big grader. cat 12 sized only had the super smooth rolling moldboard on it. Now have the D ,--looks like WD motor in it---have no idea for sure.
Always liked the old AC graders.
