What are the good, bad and ugly of this finisher? HP requirements? Have 360 hp. 4 wheeler. Is it worth it to try to find one with hd trip shanks, 150 lbs? I think. How good of seed bed in one pass on untilled 125 to 150 bu. cornstalks and untilled bean ground or won't it work at all? Am also looking at a sunflower finisher. All coments are very appreciated. Thanks!
