What Brock Grain Systems does
Brock Grain Systems, founded in 1957 and headquartered in Milford, Indiana, designs and manufactures grain storage, handling, drying, and conditioning equipment for agricultural operations. The company operates as a division of CTB, Inc., a wholly-owned subsidiary of Berkshire Hathaway, and runs six U.S. manufacturing facilities spanning Indiana, Iowa, and Missouri, plus a wholly-owned LeMar Industries subsidiary that supplies grain handling structures. Its product portfolio includes commercial grain bins up to 1.34 million bushels (EVEREST E-Series), on-farm bins, four lines of grain dryers (VECTOR Mixed Flow, SUPERB SQ low-profile, MEYER Tower, and BCT Commercial Tower) with capacities from 375 to 10,000 bushels per hour, conveyor systems, bucket elevators, bin sweeps, and supporting aeration, sensing, and control systems including the TrueGrain moisture sensor and INTUI-DRY touch-screen controller.
Brock serves three primary customer segments: on-farm grain operations ranging from small to multi-thousand-acre farms, commercial grain elevators and cooperatives requiring high-capacity storage and drying, and livestock operations needing feed storage and handling. Technology differentiation is concentrated in proprietary components: the TRI-CORR aeration floor with PARTHENON support system, TrueGrain Parallel Sensing Technology, INTUI-DRY web-based dryer control, GrainDrive tube conveyors, and the EVENFLO unloading system. These have been recognized with multiple ASABE AE50 innovation awards (2004, 2006, 2011).
The business model is B2B equipment sales through an exclusive independent dealer network across the United States and Canada, supplemented by international manufacturer representatives in Central America, Southeast Asia, and Central Europe. Revenue is generated through discrete hardware sales (storage, drying, handling, structures, feed systems, and accessories) priced by configuration and capacity, with dealers responsible for installation and service. The company has no disclosed subscription, SaaS, or recurring-revenue component. Recent strategic activity has emphasized product refresh (2022–2026 launches), a 2024 capacity expansion at the Sheffield, Iowa LeMar facility, and incremental international coverage buildout.
