I'm needing some plates for "Mexican Corn" to plant for the neigbor. I own a JD Flex 71, 4 row planter that was set up for sweet corn. The JD Dealer said about $30 a plate and Lincoln's site shows $12.75 a plate and they measure the seed in 1/64". Does anyone know what "Mexican Corn" seed size takes? As you can tell by the question I newbie to planters. bjr
