Quick follow-up-
So in the end, it looks like I did not buy a "pig in a poke." While the tiller sits close to the tractor, it is similar to what I've seen for Yanmar tillers on Yanmar tractors. For the moment I'm operational (as soon as the ground dries out a bit more). Also, the direction of rotation is correct.
Hooking it up only required the obvious- adjusting the "chain checks" and trimming the driveshaft an inch or so. So while my ignorance could have been very costly, it looks like it won't take too much to have my cake and eat it too.
My intention is to follow all the good advice here and adapt it to fit my quick hitch. That will move it 4-1/2" further back from the tractor as well as make it more convenient to mount and dismount.
My thanks to the community here for your valued insight and suggestions!
