These are from a White 6180 16-row planter. The kit contains 2 of the bolt on controllers (1 control for each 8 rows). Also comes with the needed wiring and a small box with a toggle switch used to change between normal and reduced seeding rates. The percentage of rate reduction is determined by the size of sprocket on the lower shaft such as 10%, 20%, 30%, 40% etc. New price on these are $875 each but you can buy these for $400 each plus shipping. (That's less than half price of new).

I will guarantee both units to be in good working condition and give you 30 days to use them. Install them, use them, and if not happy with them you can return them for a refund of your purchase price (less shipping cost), no questions asked.
