this is what i have been doin for the last couple of days, shifting dirt. i have been shifting topsoil away and replacing it with clay around the yard where he eventually hopes to build more silos. it pretty fun cause i have never done any earthmoving before. the 8850 has a tonne of horsepower and the tyres are full of fluid so you can drop the scraper right down and the tractor will just sit there spinning the tyres!
