Benefits and Features

While the electric drive transmission replacement on the 988K enables the significant increase in efficiency, the axles and the driveline are the same as on the proven 988K mechanical drive.

The 988K XE systems work hard to make you more efficient through advanced electric drive technology.

  • Overall efficiency improvement of 25 percent.
  • Efficiency improvement of up to 49 percent in tough applications.
  • Up to a 10 percent increase in productivity in load and carry applications.

Your operators can work more efficiently and stay comfortable with our customer-inspired cab features.

Integrated electronics provide flexible levels of information to both the site and the operator. This integration creates a smart machine and more informed operator, maximizing the productivity of both.

We are constantly improving our products in an effort to provide a safe work environment for the operator and those who work on your job site.

Enhance the productivity of your loader and protect your investment in buckets with our Ground Engaging Tools (GET). Your knowledgeable Cat dealer will work with you to understand your application and needs for the GET that is best for you.
