Our Story

Where we are from

With our headquarters in Aurora, Nebraska
and offices in Omaha, The Grain Weevil owes our
success to location, opportunity, and community.


9.7 Billion bushels of grain
are stored on farms within
500 miles of Aurora, NE.

"Build me a robot so I never have to go into a grain bin again!"

A couple of years ago, our friend Zach challenged us to build him a robot so neither he nor his kids would ever have to go in a grain bin again. Grain bins are hot, dirty, and dangerous work places. To adequately manage stored grain farmers are exposed to potential falls, entrapments, auger entanglements, and long term conditions such as Farmer’s Lung. On the nearly 450,000 American farms with grain bins, farmers take these risks over six million times a year. Grain needs to be managed during the entire storage process and a farmer with a shovel has always been the best solution. Unfortunately, this led to 20 entrapment deaths in 2020 alone. Even worse, one out of every five grain bin accidents are teenage boys.
