Looks a little lightly built IMHO. It might be alright on sandy type soils especially if you kept a tight control on grasses that cangive a roto tiller problems. The seeders like that I have used spread the over a wider strip than the cultipacker will cover also, the next pass you will be tilling seeds you put out on the previous pass. It says a 36 inch tilling width, which might be alright if you are putting in just a couple of smaller plots. You could hire somebody to put the plots in for a lot of years for $3,000 using disc and a grain drill. Those are just a couple of possible negatives, if you get one let everybody know how it works.
