I ended up buying 2 of them with clover boxes. There are 2 types of packing wheels, one smooth and the other spoked. The depth can be adjusted. It also works well for eastern gamagrass.
If you can find one, or two, they have the trailer type that could be pulled with a tool bar.
When planting, the seed is planted at the bottom of a slot which is not covered. When the seed sprouts the slot prevents the cattle from eating it. This is so you can plant directly in to a pasture as it is being grazed.
