Yep, that's the main idea - don't mow rocks with the bushhog! A box blade is my next purchase and I may get it on my next trip over to my property. Found some that look pretty heavy duty and are reasonably priced at a nearby dealer. Not sure how the box blade will do with the thick grass though. Seems to me it would pile up grass in the box and plug pretty fast. Again, works good on bare ground but might not work in the thick vegetation I have. That's why I was backing up with the tractor and bucket instead of running forward.
