Scott, yes you could procure a bolt on mule drive and use that, or fab up a bracket. <font color="ff0000">UNDER EDIT: Actually, I don't think a bolt on mule drive will fit onto a QA Cub chassis...</font> I'm not sure I've ever seen a QA mule drive used to mount a blade sub-frame but it should be possible. Hydro's suggestion might also work. The blade "A" frame should come off of the sub-frame by removing a cotter key from the rod that the blade pivots on as it is raised and lowered, then the rod should be able to slide out.
