Because there were really no combinable soil loosener for FS 15, I have made myself one. The cultivator is equipped with a rearhitch, which works selflevelling. The cultivator is made for the Kuhn Sitera 3000 seeder of Giants software. The Kuhn Cultisoil works properly without any other devices and has the functions of plows.
Please respect my work, keep my credits and keep this original link!
