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

THE RUNDOWN

BE MORE PRODUCTIVE
  • The Advanced Productivity Electronic Control System (APECS) enables communication between the engine and transmission to optimize power and torque output effectively. This integration
    results in enhanced efficiency with a net result of moving more
    material.
  • Use Ground Speed Control to set the desired top speed, and the machine will find the gear that works best for the engine and the transmission, providing a lower fuel burn.
  • The machine speed limit feature allows the machine to maintain a
    set the top speed instead of relying on top gear selector.
  • Auto-Stall assists in quickly bringing the transmission to an
    operating temperature at start-up when the machine is working in a cold climate region.
  • Cat Payload for scrapers is an earthmoving solution for optimal payload and jobsite efficiency. Cat Payload achieves on-the-go
    weighing by using bowl lift cylinder pressure during the loaded haul segment. Cat Payload is optimized to be used with Sequence
    Assist, which provides increased productivity with less operator
    effort.
WORK IN COMFORT
  • Steer with less effort with the newly designed high-pressure steering system.
  • Reduce up to 14 individual operator commands per cycle with
    Sequence Assist.
  • Enjoy interior improvements and a more ergonomic work environment
    .
  • Intuitive, ergonomic controls with multifunction display keep operators
    focused on their work.
  • Maintain desired cab temperature with automatic temperature control
    .
DESIGNED FOR SAFETY
  • Get in and out of the cab easier with the powered access ladder system.
  • Enhance the operator’s awareness of site surroundings with the
    Work Area Vision System (WAVS).
  • Convenient ground-level access to fuel fill and several maintenance points for easier
    and safer service.
  • Seat belt indicator provides visual and audible alerts when the seat
    belt is not in use.
EASY TO OPERATE
  • Cat Advanced Ride Management (ARM) seat suspension reduces end stroke movement of the load cylinder for a smoother ride.
  • Engine overspeed protection will automatically engage with no operator input when the machine is in eighth gear. The machine will assist in slowing the machine speed by canceling the throttle command and engaging the engine compression brake.
  • The spacious cab features easy, intuitive controls and excellent
    visibility. The cab provides a comfortable working environment for
    all-day operation.
INTEGRATED CAT TECHNOLOGIES
  • Access information anytime, anywhere with Vision Link™– use it to make informed decisions that boost productivity, lower costs, simplify maintenance, and improve safety and security on your job site.
  • Product Link™
    collects machine data that can be viewed online through
    web and mobile applications (optional attachment).
  • Hit target grade faster and more accurately with Cat Grade
    technologies. Finish jobs in fewer passes and with less operator
    effort, saving you time and helping to increase profit.
  • Monitor, manage, and enhance jobsite operations.
  • Shorten the learning curve for inexperienced operators with
    Sequence Assist.
