Overview

High productivity / low cost solution

Caterpillar is excited to announce the 651 comeback into our Wheel Tractor-Scraper lineup in 2022. Delivering high levels of productivity, the 651 single engine earthmoving system is a wise choice on numerous large-scale projects by providing fast cycle times when working in lower grades and rolling resistance applications. First introduced into the Cat® Wheel Tractor-Scraper lineup in 1962, the 651 continues to uphold its legacy as one of our signaturemachines. Its single engine power gives the ability to work with a Cat D10 or D11 push dozer delivering ultra-fast load times and the ability to work in abrasive or rocky conditions. Improvements in productivity, combined with enhancements in operator comfort, and new safety features – Powered Access System and effective wet disc brakes – for a machine offering high returns on profit and time

Benefits

Enhanced Operator Comfort

Ergonomic controls and a newly redesigned cab interior provide a more comfortable and efficient working environment all day long

Higher Productivity

Improvements in fuel efficiency, utilizing payload estimator, and the new transmission controls deliver increased productivity

Unparalleled Safety

Safety features help increase operator confidence by providing a safer environment for operations - effective wet disc brakes, WAVS camera, and powered access cab entry

Less CO2 Emissions

The 651 emits up to 15% less CO2 than the previous 651E.
