Upgraded D9 Dozer Has Many Improvements

Cat’s D9T bulldozer has new features intended to enhance performance, productivity, operator convenience and safety, and serviceability. The new version features a Cat C18 ACERT engine, which meets Tier 4 Final/Stage IV emissions standards and delivers 436 net horsepower (325 kW) at 1,800 rpm. High torque rise of 36% enables the dozer to power through tough material. A new high-efficiency cooling package, advanced electronic controls for the power train and implement hydraulics, quieter cab with enhanced information monitoring, and safety and serviceability refinements are major features on the new machine, which retains its predecessor’s popular features such as a durable mainframe with cast-steel main case; pivot shaft that transfers blade loads directly to the mainframe; modular drive train with three-speed power-shift transmission and differential steering system; heavy-duty undercarriage with track roller frames and bogie-suspended rollers; a wide selection of blades; intuitive controls; and expansive visibility. The previous D9T model is still available in less regulated countries and can achieve emissions levels equivalent to Tier 2 and Tier 3 standards.
