The purpose of this study is to evaluate the effect that various ripper points have on fall tillage prior to planting soybeans, as well as their impact on yield and profitability.

2018 Ohio Soybean Tillage Study - Ripper Points

We conducted this ripper study last fall with a Case IH 875 Disk Ripper on our Crosby higher clay content soils. We observed that the wider ripper points required more horsepower and fuel, which led us to believe that they were doing a better job of fracturing the subsoil. This, however, did not lead to increased yields the following season.
