I'm asking this to help out a neighbor of mine. He purchased a new to him JD 7000 planter with Kinze brush meters. He wants to seed 42 pounds of the soybeans he has per acre. I'm not sure what plate he has installed or the seed size of his beans at this time. He needs to know what sprocket combination to run to achieve this rate. Does anyone have access to a chart, or some knowledge I can pass on to him? Thanks in advance!
