Where can I find out how to set the population for my Kinze brush meters that i'll be using in a JD 7000. I suppose I could go to a Kinze dealer but I bought them used and they didn't come with a chart. If sombody could scan and post or scan and Email it to me that would be great. The planter is a JD 7000 6 row 30 inch. Thanks. [email protected]
