Benefits and Features

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

Cat Connect makes smart use of technology and services to improve your job site efficiency. Using the data from technology-equipped machines, you'll get more information and insight into your equipment and operations than ever before. Cat Connect technologies offer improvements in these key areas: Equipment Management – increase uptime and reduce operating costs. Safety – enhance job site awareness to keep your people and equipment safe.

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.

Data from customer machines show Cat Wheel Dozers are among the most fuel efficient machines in the industry. Several features contribute to this excellent fuel efficiency:

  • ACERT Engine – Advanced engine controls maximizes power and efficiency.
  • Engine Idle Shutdown – Automatic engine and electrical system shutdown conserves fuel.
  • Lockup Torque Converter – Transfers more power to the ground and optimizes fuel efficiency in all applications.
  • Single Clutch Speed Shifting (SCSS) – All new SCSS transmission controls provides greater momentum on grades and fuel savings by carrying that momentum through the shift points.
  • Fuel Tank Capacity minimum of 12 hours operation depending on the application.

Machine configuration, operator technique, and job site layout can impact fuel consumption.

  • Machine Configuration – Select the correct blade configuration based on your individual application.
