Based on my own experiences with a tiller I would broadcast your fertilizer and lime, till the plot, broadcast your seed and then cultipack if you have one or simply use the tires from your tractor, ATV, lawn mower to push the seed into the seed bed. I am really considering doing this this year instead of using my planter simply for something different. The "fluffy" seed bed a tiller makes - makes pushing seed into the soil a breeze and you don;t risk smashing the seed. It also allows the kids to help - I just tell them to go drive around in the dirt and they will have a blast.....they will have no idea they are helping! I am also considering adding in some corn or sorghum for some cover as well. If I add corn it will be RR and planted at the same time as the beans. If I use sorghum it will be after the gly application to address any weeds. Sure I could save some seed by row planting, but I like to try different things and my seed is mostly free anyway so big deal.
