The yellow meter roller only shows to be able to seed a minimum of 2# per acre and I’ve been told they are not very accurate at the extreme low or high end of their specifications. Is it possible to change the main drive sprocket to slow down the transmission enough so that it doesn’t have to be set all the way to zero? I’m wanting to seed a particular brand of sesame and the company recommends a 1-1.5 pound per acre seeding rate. At $900/bag I don’t want to be overseeding even a half pound per acre! Has anyone done this?
