Take a look back on SRES’s innovative and historical milestones

  • 2005

    • Sold our first MS (Mini Seed) Planter and a new control system developed to expand our product line. The new control system was named “Classic” and the previous system “Advanced.”  These systems are still sold today and are unique in the marketplace.
  • 2008

    • Introduced the Runabout planter. It is a small planter aimed at the vegetable market and some of the “off crops” like peanuts. We changed the industry by introducing GPM Software for research plot planters to use for laying out their plots.
  • 2009

    • Stacy Unruh purchased shares from Jack Hefling, and he left the business.
