I guess that is the second part of my question. Would a grain drill be ok for planting small clover and brassica seeds? I would also like something that is three point mounted to ease transportation between properties.
One of the major advantages of a no-till drill (if you are indeed looking at no-till drill) is not having to work the ground...you can just seed right into the existing vegetation, with no need to disc or till - conserving soil moisture (and potentially saving a lot of time and diesel fuel). Some pretty good tractor HP is required to pull a no-till drill through the plot.
If you still plan to work the ground with a tiller, you would be able to use a "regular" grain drill that is much cheaper and requires much less HP to pull. Three point hook up would be fantastic, allowing you to back into the nooks and crannies of food plots and plant your way out.
Good luck in your search, and please keep us posted on what you decide to get and how it works!
I'm almost certain that I do not have the horsepower to pull a no till. At a minimum I would want something 6' wide to cover the tires of the tractor. I will continue to rototill the ground to mix the lime and fertilizer in.
Thanks for the information. I'm going to start the search for 3pt grain drills.
