  • TThe latest generation D8T bulldozer brings new features to help you be even more productive, even in the harshest conditions. A proven power train, increased cooling capacity and a larger blade help you move more material, while a choice of Cat GRADE technology options help you get more work done in less time.


More productivity and up to 10 percent fuel savings means you move more material with every liter of fuel.


Whether you work in desert heat or arctic cold, equip your D8T to take on the toughest conditions.


The largest Semi-Universal blade in the size class helps you move more material with every pass.

Added productivity and up to 10 percent fuel savings, delivering up to 18 percent better dozing efficiency than previous model D8T.

Cat C15 engine delivers more horsepower, with more than a decade of proven reliability in a wide range of working conditions.

Optional electro-hydraulic controls reduce operator effort, improve precision and response, and enable Cat GRADE technologies.

Standard Slope Indicate displays machine cross-slope and fore/aft orientation right on the main display.

Cat dozers are designed with features like wide engine panel access doors to minimize maintenance and repair time.

Engine enclosure doors are solid at the bottom to help reduce the amount of sand carried into the engine compartment for improved cooling and reduced cleanout time.

Operating Weight 87600 lb

Ground Pressure (ISO 16754) 7.7 psi

Air Conditioning The air conditioning system on this machine contains the fluorinated greenhouse gas refrigerant R134a (Global Warming Potential = 1430). The system contains 2.5 kg of refrigerant which has a CO2 equivalent of 3.575 metric tonnes.

Cat buckets and Cat Ground Engaging Tools (GET) are designed and matched to the machine to ensure optimal performance and fuel efficiency.


Center-Lock is a pin grabber coupler and features a patent-pending locking system. A highly visible secondary lock clearly shows the operator when the coupler is engaged or disengaged from the bucket or work tool..


E Series hammers bring together customer expectations for performance, quality, and serviceability along with Caterpillar manufacturing expertise. They are also quiet – a significant benefit in urban and noise-restricted work areas.


Constructed from high-strength steels and built to last, Cat rippers endure in the toughest conditions. The box-section structure is reinforced for maximum rigidity, transmitting the full machine power to the material being ripped. Rippers feature a replaceable wear tip, and most models also come equipped with a replaceable shank protector.
