Fix for Tail end dragging while going up driveway

My newly purchased 2004 3023 back end drags while going up our driveway. I removed the optional hitch thinking that the 2-3" difference would eliminate the problem. It didn't!

I could reinstall the hitch and buy a hitch wheel, but that would get the back end down about 4-5" and isn't the solution I'm looking for.

Has anyone installed wheels to the frame to avoid this issue, or have any suggestions on what can be done to eliminate the problem? I really don't want to rip out part of the existing driveway and pour a new one.

2" X 12" boards may work, but will be cumbersome.

Any help is appreciated!!
