Closing Wheel Study

2017 Iowa Corn Closing Wheel Study - Placement

  • Iowa

The purpose of this study is to evaluate Schaffert’s 4 Link Closer and its effect on emergence, yield and profitability.

OBSERVATION

In this study, the Schaffert walking axle closing wheel system resulted in more consistent emergence than the other two treatments. On the other hand, the final stand with the walking axle system was much closer to t he planted population. However, that did not necessarily translate into a larger yield gain. Both of the Schaffert systems we tested appeared to have better mechanical characteristics that provided a better, more consistent soil contact than the standard closing tail.
