A brand that is known across the agriculture and construction industry: Caterpillar. Caterpillar has been producing diesel engines for nearly 100 years, which is no small feat. The founders, Holt and Best, initially started as competitors. Eventually, the two came together and became a team of innovators that changed the industry as they knew it. This partnership is what led to the success of the Caterpillar track-type vehicle that we’re all familiar with.

At the time that these two began working together, horses were still the power behind infrastructure and agriculture tasks and industries. Holt and Best were determined to find a solution that improved the productivity and work of their clients.

The track-type design that we recognize on Caterpillar equipment was initially designed to help farmers who were having a hard time getting work done because of how soft the soil was. Initially, the design was only used on the back half of the tractor, but we’ve since seen this design utilized as the primary means of moving the vehicle.

Holt is recognized for improving the design of the tracks, but while he was focusing on that aspect, Best was working on easy to affordably fuel these pieces of equipment so they could be used to work harder and longer. Caterpillar has seen their equipment utilize steam, gas, and eventually diesel engine. This evolution is one that has always kept the individuals using the equipment top of mind.
