Does anyone have much experience with either of these products? We drill with a 4m Horsch Sprinter, pulled by a Fendt 724, and I'm wondering if we have enough 'grunt', and whether people believe that these are good machines. We currently use a 3m Sumo Trio to prepare most of our ground, but we find it quite "destructive." As we are in the SW, heavy September rainfall can also make our seedbeds very mushy if we have worked too deep, too early. Many thanks.
