  • Page 3 Introduction The GCRO 7010 and 7012 disk harrows were specially designed for great areas. They are ideal for the initial preparation or for leveling the soil, with excellent application and soil preparation for annual or perennial crops. Their reinforced and adequate structure are made of folded steel plates joined by a good penetration weld and fine finishing, with resistant parts on the load concentrations.
