Product Description

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
