About Cowboys & Engines

Our diesel technician, Benjamin Boyd, has over 25 years experience working on diesel trucks and equipment. As a graduate of WyoTech in Laramie, Wyoming, he returned home to South Texas to hone his skill as a diesel technician.

Having worked for a diesel truck dealership in San Antonio for almost 10 years, in 2009 he decided it was time to start his own business and offer his services in his hometown and the Atascosa County area to meet the growing demands of the diesel industry.


In 2010 with the oil field boom in the Eagle Ford Shale, the business quickly grew and since then Cowboys and Engines has worked hard to continue to meet the needs of the various industries in our area as well as maintain good working relationships with business owners, ranchers, and owner-operators who have faithfully been our customers for years.

As the demands change and the industries change with them, Cowboys & Engines continues to provide professional service to our community, knowing that booms in business may come and go, but the need for a qualified, honest, hard-working diesel mechanic will not go away. We’re here to stay.

Only the Best


Commercial Trucks

We cut our teeth on commercial trucks. We understand that commercial transportation is the driving force (literally!) behind almost every single industry and that when trucks stop, you stop. Business stops. This is why we make it our job to quickly and efficiently get you back on the road. We know those loads won’t deliver themselves and people are depending on you which is why you can depend on us to work hard so you can keep on truckin’.


Heavy Equipment

Heavy equipment brings its own challenges in the construction and oil field industries. These machines are put through the wringer in this rugged Texas terrain. They are big, heavy, expensive,  and abused the heck out of. This is why when they break, it can break your heart…and the bank. We get it. We have been working in the Eagle Ford Shale area for years putting these bad boys back to work and you can trust that your equipment will be fixed right the first time.


High Quality Construction Management

I work hard to meet the needs of the various trucking, construction, and oil field industries in the South Texas area as well as maintain good working relationships with business owners, ranchers, and owner-operators whom I provide professional service. A good reputation is important to me and my work has always reflected that.
