Just bought a 15ft Tye Grain drill with a no till caddy on it. Was previously used to plant beans etc. This will sound dumb but I no nothing about this drill and purchased because it seemed like a decent deal and needed a unit to plant hay crops and cover crops etc. I would like to know if anyone on here knows how to adjust the seed flow rate on this type of drill. I have a manual on the way but would like to know anyones previous experiences with adjusting. I will be planting rye grass, cereal rye, and wheat primarily. Drill seems to have the sprocket on the side of it with a chain running to the drive sprocket. I do know this controls the speed of the drill however is there a way to close and open where the seed drops out of the drill into the seed cups to slow the seed rate down?
