This 1980 John Deere 4640 was made for cultivating corn. Attached is a John Deere 845 I think, 12 row 30 inch cultivator that is 30 feet wide, heavy and does a great job. I bought it up in central Ohio and when I was bringing it home everywhere I stopped somebody told me that they hadn't seen equipment like that in 30 years. They should have seen me today cultivating 44 Acres of bloody butcher open pollinated high protein heirloom corn. I am halfway there on the 1st cultivation. | Autumn Olive F
