Provides power, reliability and acts as a working counterweight in the rear of the machine, for optimum machine balance.

Operator Station

Designed for operator comfort, convenience, and ease of operation throughout the workday.

Monitoring System

The gauge cluster provides all necessary functions and information within the operator’s normal line of sight.

Hydrostatic Drive

The electronically controlled hydrostatic drive helps provide quick response for shorter cycle times and increased productivity.

Implement System

Work smart and move more

SystemOne™ Undercarriage

The SystemOne undercarriage was designed exclusively for Caterpillar machines to reduce customers’ operating costs, downtime and maintenance intervals.


Durable Slab section Frame and Loader Front End: Durable with increased space claim for larger components.

Special Application Arrangements

Special arrangements improve the 963D’s performance in special applications.


The large variety of tasks an operator can perform with the standard machine and Work Tools has lead to the Caterpillar Track Loader’s reputation for versatility.
