Overview
Nearly half of the large dozers Caterpillar sells are D9 dozers—and for good reason. They’re the smart choice for dozens of applications and environments thanks to unmatched reliability, long life and a wide range of application-specific blades.
Like all Cat® dozers, the productive and efficient D9 is a fully integrated Cat machine—100% designed by Caterpillar and built with all Cat components that work together to deliver top performance and high availability. With the D9, you’ll move more dirt at the lowest possible cost.
