Our In-house Brands

PDI over the years, has built an entity of in-house brands to the point of which they make up 30% of our business however, contract manufacturing for customers will always be our number on priority.  Manufacturing our own products allows not only our in-house brands to grow by constantly innovationg but also allows us to become more resistant to global economic changes.

AgSolutions was founded in 2003 by the Glazik brothers, Steve and Gary, who together, with Steve's sons Matt and Alex manage corn and soybean farm land in the Illinois counties of Ford, Iroquois, Champaign, and Vermillion. And Like many farmers, the Glazik's had to deal with flooded, ponded, and saturated soils that affect and impact crop growth, and they knew the best way to tackle ponded water, and remove excess moisture from the ground was a strategically placed tile system, but a tile system only works if they remain clog free.  

As they say, "need is the mother of invention" and so, Steve and Gary took matters into their own hands and created the Quick Drain Intake, that allows more water in while keeping leaves, stalks, and other debris out of the inlets,and thus, AgSolutions came to fruition.

Since its inception, AgSolutions has primarily focused on agricutltural drainage products that are proudly made in America, and has since expanded into famr equiment upgrades, including the design and development of the Acre Plus which allows for more than a bushel of seed to be carried in a John Deere or Kinze planter box, saving farmers both time and money.
