Hello, I have roughly 15 acres I'd like to spread some bermuda seed on this Spring - and another 30 acres next year if this goes well. I've disc'd the area and am looking for a good spreader to pull behind a 4 wheeler. Any advice? Also, once I've spread the seed, what's the best way to get it at the right depth in the soil - dragging again with some old tires or chain link fence? Thanks in advance - this will be my first attempt at this.
