R.W. Mercer Co. Agricultural


R.W. Mercer Co. Agricultural Division is a comprehensive source of agricultural grain system sales, design, installation, millwright work and service. We provide grain storage bins, grain handling systems and the industry’s most technologically advanced grain dryers, all from Grain Systems (GSI)—the world’s largest manufacturer of grain management systems.

As an authorized GSI Inc. dealer, we are capable of meeting the needs of any size agricultural operation. Because we’ve been around since 1960, we have the expertise of a highly trained and skilled workforce to complete your grain system on time and within budget. We also offer GSI Zimmerman all Farm Fans, tower dryers and Intersystems equipment.



If you’re in the market for a farm bin or a commercial-grade bin, Mercer supplies the GSI grain storage system to hold your type and level of grain production. Made of heavy-duty corrugated steel, we can design and install any combination of storage systems to your specifications. We also offer a variety of wet holding tanks and hoppers to increase organizational efficiency while grain is being dried.


GSI manufactures the largest selection of advanced grain dryers in the industry, which is why R.W. Mercer Co. chooses to be an authorized supplier of GSI grain conditioning systems. From single-fan competitor dryers and in-bin aeration heaters to GSI’s-own patented X-STREAM™ and TopDry drying systems, Zimmerman and Farm for tower dryers, we are well-versed in implementing any grain conditioning configuration. The more efficient you can dry your grain the better your ROI will be when purchasing GSI equipment.


Whether you’re moving grain from harvest to conditioning or conditioning to storage, look no further than GSI’s grain handling systems. From small farms to large commercial operations, we can design and install a conveyance system to meet your needs. Bucket elevators, paddle conveyors, air systems or augers: we’ve got what it takes to move you—and your grain. Mercer is also a Lambton dealer for grain legs/pits/conveyors.
