Cowboys & Engines

Fully Mobile Commercial Truck and Heavy Equipment Repair Company

Commercial Truck repair

Cowboys and Engines specializes in commercial trucks, tractors, and trailers. We do it all bumper-to-bumper, even if you’re on the road and need emergency services.

Heavy Equipment Repair

Construction heavy equipment is big business in South Texas and we know these machines mean everything when they are down. We work hard to get your heavy equipment back up and running without the ridiculous price tag of the other guys.

Diesel Engines

With over 25 years of experience working, diagnosing, and repairing diesel engines. We offer complete service and repair including complete engine overhauls and rebuilds. 


We specialize in the specific needs of our heavy equipment customers which include hydraulic cylinder repairs.


We build and perform specialized maintenance programs for our larger customers including oil changes and DOT compliance.

Mobile Services

Our qualified diesel service mechanic works quickly to properly diagnose and repair your diesel equipment so you can get back to work as quickly and efficiently as possible. 


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.

Commercial Truck & Heavy Equipment Repair

Cowboys & Engines LLC has been in business since 2009 serving South Texas’ diesel transportation, construction, farm and ranch, and oil field equipment needs. Getting our customers up and running and back to business when their trucks or heavy equipment is down is what we do. 

We know that when your machine is down you’re losing money, which is why we offer fully mobile repair service. Our mobile mechanics work quickly to properly diagnose and repair your diesel equipment so you can get back to work as quickly and efficiently as possible. 

We’re not going to waste your time giving you the run around on what might be wrong or try to take advantage of you by selling you on a bunch of stuff that’s not wrong with your equipment like some mechanics and truck shops do. That wastes our time and yours. And we all know that time is money.


Our diesel mechanics have over 25 years of experience professionally diagnosing and repairing commercial diesel trucks and heavy equipment for businesses just like yours. 

Whether you are a construction company, an oil field company, or you run a farm and ranch with lots of heavy equipment and machines, we have you covered.

We know the industry, stay on top of new technology, and we keep up with the newest changes in engine systems for each industry.

This has made Cowboys & Engines what it is today.
