I've never heard of side-to-side tilt on a 3 pt attachment, unless you mean by adjusting the threaded rod positioning the lower lift arms (a slow and tedious operation). These aren't dozers.
I have seen a few blades that have the ability to tilt or angle one edge lower than the other to allow for cutting a slight grade. I don't want to adjust the 3pt arms to do that (you're right, slow and tedious for sure). The offset would allow me to work past the edge of the tractor and the tilt would allow me to cut a grade as I go. Not trying to replace a dozer, just trying to make it more useful for landscaping projects as I go along the way.
Thanks for the reply
