When it comes to unloading seed and agricultural materials, O’Mara Ag Equipment in Iowa has you covered. Our American-made, custom-built dump systems are engineered to suit your operation, whether you’re running a high-volume processing plant or managing batch unloads in a tight space.
With over 200 years of combined experience in seed, popcorn, and edibles plant design, our team knows what it takes to make a dump system work in the real world. We offer a wide rangeof unloading equipment, designed and manufactured in-house, and proven across industries.
From drive-over dump doors to rotary box dumpers, every system is designed for efficient, clean, and safe product handling, with options for food-grade, severe-duty, or fully automated applications.
We don’t just build equipment—we build relationships. We take a flexible, hands-on approach to understand your unique unloading needs and create systems that integrate smoothly into your operation. Because everything is built in-house, you get full visibility and consistent quality at every step.
Built for bulk seed, pro boxes, or 50-unit totes, our Rotary Box Dumpers combine rugged strength with operator-friendly features. A heavy-duty steel frame, built-in hopper, and adjustable sensors come standard. These units are plug-and-play ready for integration with your control system and include a clean dump feature to reduce waste and contamination.
Streamline your unloading flow without disrupting traffic. Our hydraulic drive-over doors allow full trucks or wagons to pass over the pit and unload directly where needed. When closed, the doors act as a backstop to reduce product splash and keep your workspace clean.
