In the last pic it looks like it is centered , and the pic above that looks like it is offset.
Looking at the very first pic you can see that the adaptor thingy is centered in sleeve hitch adaptor.
A way to offset the plow is what you want , but you would have to redo the adaptor to offset the plow.
The chain/bolt idea like robpa said would work to try the plow in some dirt , and you are going to have to get the lift/plow on the same plain. What i mean is , the lift not all the way up and the plow all the way down , vice/versa.
I hope all that made sense !!!!!!!!!
