(Radio Iowa) – A northwest Iowa business that makes trailers for hauling livestock and grain will be laying off dozens of employees this fall. Sioux City’s Wilson Trailer Company has notified the State of Iowa it will be laying off 58 workers on September 30th. By law, businesses that have more than 100 employees are required to provide 60 days advance notice of layoffs. Employees were notified Thursday.

The company, in a written statement, cited slowing trailer sales in the agricultural market as the reason for the layoffs. Wilson Trailer Company, founded in 1890, is a family-owned business with headquarters in Sioux City. It operates five production plants, including two in Sioux City. The rest are in Moberly, Missouri, Yankton, South Dakota, and Lennox, South Dakota.

In addition to trailers to haul grain and livestock, the company makes flatbed and gooseneck trailers.
