Didn't intend to hijack this thread, so here's the final test result.
This poor old rotovator came with the tractor, and I haven't had a chance to mess with it, so it's been sitting in the weeds waiting for some love. Today as a test of the (guess I should call it a dolly) dolly, I dug the rotovator out and moved it to where I could simply hook it up to the tractor. Slick as could be.
Also in the "wild hare" department, I realized that I can easily set the rotovator up on some sturdy work stands to give my old bones some respite during reconditioning, as well as reposition if needed without firing up the tractor.
Another thought would be, stacking attachments at least two high (with proper stands) to save even more storage space.
The only thing besides paint for the "Dolly" is a simple brake of some sort because it rolls so easily that even on an almost imperceptible grade, it wants to sneak off before I can throw a chock in front of the wheel.
A Happy Camper
