I use a chain harrow for light maintenance, its about 8 foot section of 5 ft chain link fence folded over a "T" post and chain to tractor draw bar.... If I need weight on it I throw on a 4 ft section of RR track or a selection of large rocks...... Have been mentally working out grading without box scraper, by getting simple blade scraper and putting a pair of skid shoes on each end (sort of like ends of box scraper) to keep it from cutting deep, and sort of just scalping the high spots.... By removing "skid shoes" it goes back to being just a scraper....
