And the third group, D9, D10 and D11 will continue to be what they’ve always been-heavy push dozers. The D5 to D8 dozers comprise a second group of dual purpose machines geared for both heavy dozing and finish grading. As with the D11R, the D11T Carrydozer can push 57. It comes as a regular bulldozer and a carrydozer like the previous model. From D5 and up you’ll see the Caterpillar’s elevated sprocket/high-drive design.

There will still be annual product updates and new feature sets for dozers and other machines, but contractors will need to know the year-model or the serial number to know which machines have which updates. In the past, the suffixes on Cat dozer names typically designated different feature sets. Meeker says you might/could see this on dozers a year or two down the road.
