Overview

PUSHING YOUR PROFITS FORWARD

The Cat® D8 (formerly D8T) bulldozer helps you maximize your productivity, even in the harshest conditions. Cat C15 engine, combined with Auto Shift, means you get plenty of pushing power without sacrificing fuel efficiency.

Benefits

Efficient Dozing

Move more material at a lower cost. Proven power train and Auto Shift give you both power to the ground and fuel efficiency.

Up To 13% More Material per Pass

At 10.3 m3 (13.5 yd3), the Semi-Universal blade is the largest standard blade in the size class, so you get more done in fewer passes.

Extreme Performance

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