At the Kansas Agricultural College, experiments were carried on

 Besides having four shovels to loosen up the soil, the front 

 shanks are equipped with a short knife blade which cuts oil

 cultivating after the ordinary season for cultivating was past. The 

 soil on which this trial was made was a black, friable loam, (Bulletin
