My brother and I are going to be leasing 130-250 acres of new ground this fall. The ground has been sitting for a few years and looks terrible. We are thinking of growing some grain crops to clean things up and try something new. I have a line on a John Deere 6620 sh titan. Would this combine do the trick for a few years on this kind of size operation. I have farmed forage crops and have all the tillage and planting equipment, but have never grown anything for grain let alone run a combine? Does anyone have any advise on this?
