About Us

Founded in 1967 as Bell Detroit Diesel, Bell Power Systems has been one of the nation’s leading authorized distributors of John Deere diesel engines since 1989.  Bell has also been a leading distributor of Yanmar Industrial Diesel engines since 2005. Our sales territory covers the eastern United States from Maine to Virginia as far west as New York and Pennsylvania. In 2012 Bell Power Systems became a part of the Superior Diesel family of companies. Together, we specialize in providing value-added diesel engine packages, service parts, and drivetrain components to original equipment manufacturers and dealers for off highway equipment applications. 

Currently, Bell Power is located in a 60,000 square foot warehousing and manufacturing facility in Essex, Connecticut. The company maintains an inventory of 700 to 900 engines covering 4 to 600 Horsepower and serves OEM's and dealers throughout its territory in industries ranging from pumps to aircraft ground support to construction to agriculture to railroad and highway maintenance to generators and marine propulsion. Bell Power develops and provides custom engineered packages to meet the needs of any application requiring reliable heavy duty power.

In 2015, Bell Power expanded their facility by 13,000 sq. feet and added an additional 129KW of solar power by having over 400 new solar panels installed.
