Let's face it. Purchasing heavy equipment — whether it's for earth moving, tilling, or some other application — always requires a hefty investment. And it means thinking about the long-term optimization of your machinery's lifecycle and ROI as well as optimizing the short-term value of your purchase. If this sounds like your situation, you'll be pleased to hear about Yellowmark™ — the new line of repair and replacement parts from Caterpillar®.

Caterpillar Equipment and Parts

For decades, Caterpillar equipment has been the go-to option for contractors looking for quality, reliability, innovation, and value — and for the option to repair older equipment with Genuine Cat® Parts. This in turn helps maintain the performance of the equipment, which can be sold back to Cat dealers and then re-sold as used equipment.

In short, once you've made an investment in Caterpillar equipment and you maintain it properly, you can count on getting a good ROI, both in terms of the performance of the equipment and its resale value.

Yellowmark™ Parts Available Throughout Alabama

Caterpillar developed Yellowmark™ as a line of repair and replacement parts intended to balance convenience, reliability, and affordability. In comparison to Genuine Cat Parts and Cat Reman Parts, Yellowmark™ is a value-priced alternative.

The Yellowmark™ line offers over 6,000 parts for small and medium-sized Cat construction equipment, including excavators, loaders, dozers, and graders. Examples include structural parts, ground-engaging tools, hydraulic parts, drive train parts, engine parts, and undercarriage parts. While Yellowmark™ parts still offer good value and support the performance of your equipment, they don't offer the same premium performance, durability, low cost per hour, and maximum ROI as Genuine Cat Parts and Cat Reman Parts.
