“I have used Dawn Curvetine closing wheels for many years. In 2021 I decided to install Furrow Force on half the planter. I ran this for 2 years and documented the yield results. The Curvetines were alway as good or better than the Furrow Force, up to 5 bushel better. In 2023 I removed the Furrow Force and installed Zippers, I ran this setup the next 2 years. The Zippers were always better than the Curvetines, up to 5 bushels better.”
