i have two old John Deere drills that are seldom used. Most of the time i disk the ground and hand broadcast the seed. A drag made of railroad ties and chain link is dragged across the furrows made by the disk. It does a good job of covering the seed. i can hand broad cast two acres in less than an hour. Besides its good exercise.
The thing in the photos is a pasture drill. It does not have individual plates. The fertilizer side and the seed side have long sliding plates that are infinitely adjustable. It does a good of overseeding game plots and pasture. This year i'll plant some peanuts with it.
