Chief Agri systems are engineered for structural strength and long-term reliability, but performance depends on proper installation. Sentry’s self-performed approach means our crews handle foundation layout, anchor bolt placement, structural erection, electrical integration, and controls installation.
Our Controls & Automation division builds monitoring and automation panels in-house, and our Crane Service handles heavy equipment placement. This single-source execution eliminates coordination delays and ensures every component is installed to specification.
We sell and install Chief Agri Systems across South Dakota and the Midwest.
