Strong, efficient, and ready for anything that South Dakota weather might throw at it. With quality-built bins and equipment, you can protect your harvest and plan for growth with confidence.
For over two decades, Wentworth Ag has been trusted by farmers across the prairies for grain storage solutions. In South Dakota, we bring the same experience to farms growing corn, soybeans, wheat, and other crops — all while understanding the state’s unique mix of humid summers, rapid harvests, and harsh winters.
South Dakota farms range from the row-crop belt in the east to cattle-grain operations in the west. We understand these regional differences and provide tailored solutions no matter your location.
We offer more than bins — from site design to installation and grain management tools, every piece of your setup is coordinated for performance.
By working with leading brands, we supply bins and handling systems built to handle South Dakota’s wind, snow, and temperature swings — protecting your investment season after season.
Wentworth Ag delivers grain storage and handling equipment suited to South Dakota’s high-yield crops and fast harvest cycles. Our lineup includes flat bottom, hopper, and smooth wall bins from GSI, an industry-leading bin manufacturer — designed for efficiency and built for tough SD weather.
We also provide dryers, aeration systems, conveyors, and bucket elevators, allowing farmers to set up complete, integrated systems. Whether you’re looking to manage corn at high moisture or create long-term soybean storage, we’ll help you select the right equipment to match your operation.
With decades of prairie experience, we go beyond equipment sales. We offer continual guidance, layout planning, and dependable service. Whether you’re adding a single bin or building a large-scale site, Wentworth Ag helps South Dakota farmers store smarter and grow with confidence.
Choosing the right grain bin in North Dakota involves way more than just picking a size. Here are some of the key factors that influence the decision — and how we can help you address them.
South Dakota’s corn and soybean harvests can create enormous volumes in a short timeframe. We help size bin systems to handle today’s big yields while allowing room to expand as operations grow.
Efficient site layouts are crucial when you’re moving grain carts, semis, and dryers all at once. We design bin yards that streamline traffic flow, reduce bottlenecks, and leave space for future upgrades.
South Dakota’s open prairies face powerful winds, thunderstorms, and heavy winter snow. We guide farmers toward bins with anchoring and roof designs built for these realities, minimizing long-term risks.
Freight, foundations, and add-ons like dryers can drive up project costs. We help farmers map out budgets clearly, balancing immediate needs with scalable infrastructure for the future.
With everything from corn to soybeans to specialty crops, you need flexibility when building grain storage in South Dakota.
That’s why we pride ourselves on helping you find the right bin(s) for your yard, while avoiding stress and costly mistakes. From the first contact to ongoing support, we will work alongside you to make sure your storage system is ready to meet both today’s needs and tomorrow’s growth.
South Dakota farmers work some of the largest acreages in the country, with over 42 million acres operated across 28,000 farms. That scale, paired with massive corn and soybean harvests — with ~5.9 million acres of corn and ~5.5 million acres of soybeans planted in 2024 — creates intense pressure at harvest time. Farmers tell us bins fill quickly, and planning for both capacity and grain flow efficiency is critical to keeping up.
Livestock production adds another layer. With 3.5 million head of cattle and 2.2 million hogs, many operations juggle grain storage for both sale and feed use. This mix of needs means farmers here often ask about flexible setups: bins and handling systems that not only protect grain quality but also make it easier to divert feed when needed.

Q: What grain bin sizes are most common in South Dakota?
A: The most common grain bin sizes vary widely, but a lot of farmers in SD choose mid to large-capacity bins for their wheat, canola, soybeans, or whatever else they’re looking to store. If you aren’t sure, we can help you determine the right fit based on your operation and crop mix.
Q: Do I need a permit to install a grain bin in South Dakota?
A: You may not need a building permit to build a grain bin in SD, but you’ll likely need to ensure that you’re following building code, especially if there is electrical work involved. This can depend on which county you are in. We can identify what permits/complications to be aware of based on your county/bin needs.
Q: Can I add a dryer later if I don’t install one now?
A: For sure — we design our grain storage systems with future upgrades in mind. Planning for this flexibility upfront is key, and our team can ensure your site is set up for phased expansion, should you choose to go that route.
Q: How long does it take to get a bin installed?
A: Timelines can vary based on product availability, weather, and site prep. We can give you a clearer timeline of your project once we understand its scope and location.
Q: Do you offer grain equipment across South Dakota?
A: Yes — we serve customers across South Dakota, as well as into North Dakota, Minnesota, Montana, and even Canada. Ask us about delivery and installation options in your area.
