I need to update my old corn planter soon. Could someone explain to me the pros & cons between the 71 Flex and 7000 series planters. I will be planting corn and pumpkins I've been told that a 7000 can plant pumpkins, is this true? Also, the planter needs to be a 2 row but I'm having trouble locating a 2 row 7000 3pt hitch on the internet for sale. I'll be planting roughly 15 acres, mostly small plots (Indian Corn) & I'm afraid that if I go with a 4 row I'll spend more time turning around than planting. Any suggestions? Thanks & God Bless!!
