Serving the Mid-West Agriculture Industry with efficient, friendly service since 1939 from Warren, Indiana.

Welcome to The Daugherty Companies, Inc. website. Beginning as a J.I. Case dealer in 1939 at the corner of 1st and Main St. in Warren, Indiana as Warren Farm Supply, our company has been a solid partner with agriculture throughout the years. Evolving from a retail dealership to a wholesale and manufacture’s rep organization in the early 1960’s, Daugherty’s were the dealer contact for many short- line companies in the central mid-west. Names like Cropguard, Schwartz, Dickey-john, Hypro, Snyder Industries, Cozy Cabs, Ag Leader, Trimble and Monarch Industries were part of the Daugherty portfolio.

David Daugherty expanded the electronic side of the business in the early 1990’s to manufacturing where he designed and built the first monitoring systems for grain drills – The Vanguard System. The manufacturing expanded to building wire harness and systems for farmers, dealers and OEM manufacturers.

In December 2019, the manufacturing and distribution portion of the business was sold to Ag Express Electronics and the The Daugherty Companies, Inc. name was retained to preserve the over 80- year heritage. Mike Daugherty (third generation) now operates Ag -Serv from our facilities at 535 S. Grover St. in Warren.
