Once you figure out your best course of action and decide to roll later on down the road, your x485 will handle a roller easily. I would recommend the largest you can get...like the 24" x 48" metal water filled type. There's 2 "economy" ones out there...Agri-fab (910lbs filled)and Ohio steel (860lbs filled). You can put sand in them as well...as long as it's dry and you have the time to pour it through the small fill hole. Water will expand in winter so empty it before it's too late. The water in my roller froze near the fill hole and I could not get the plug out. I made the mistake of taking care of a laundry list of things to do and forgot to bring it in the garage or heat the plug area right away...the roller expanded apart from the shaft...need to repair it now. I found a lot of uses for the roller, but like the others have already said, it won't level ot your land...just will help push down or compact some particular areas. I used mine on my crushed rock driveway, compacted some fill soil, flattened out some sod, pushed down some tracks made in wet soil, etc. Have fun, be patient...you have a lot of acreage to dress up. Post a pic too...you'll get some more ideas from some people with similar projects.
