Overview

The D6T series comes in a range of models including the standard D6T, the D6T LGP, D6T XL, D6T XW and the D6T LGP VPAT. Each has their own features, benefits and applications, but for the sake of time and their popularity, we are comparing the standard to the XL.

The D6T dozer series offer smooth shifting, fully automatic 4-speed transmission. This allows for the power train to be continuously powered for dozing, even against sudden heavy loads. When you’re pushing sand, gravel, dirt and other heavy materials, these dozers will not let you down.

Operation

  • Half-gear and one-tenth gear increments give you total control of ground speeds
  • Updated joystick to increase ease of operation and productivity

Notable differences in these D6 dozers:

When you see ‘XL’, you think ‘extra large’—but is that really what this stands for? Let’s find out.

According to their specs (see below), the Cat D6T (STD) is ideal for your run-of-the-mill, general dozing jobs. While the D6T XL offers more power, lifts higher, has greater cutting depth, wider tracks, and can be equipped with narrow blade/push arms for easier transport.  

It isn’t technically ‘extra large’, but it does offer more power for pushing extra large loads. So if you’re constantly doing jobs on the larger scale, the XL may be the way to go.
