651 Open Bowl Scrapers

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 Tractor Engine Cat C18 Flywheel Power – Tractor/Scraper 469kW (629 hp) Net Power 469 kW/637 hp Product specifications for 651 Open Bowl Scrapers Engine expand / collapse icon Tractor Engine Cat C18 Tractor Engine expand / collapse icon Flywheel Power – Tractor/Scraper 469kW (629 hp) Net Power 469 kW/637 hp Gross Power (SAE J1995) 475 kW Net Power (ISO 14396) 436 kW Bore 145 mm Stroke 183 mm Displacement 18.1 l Net Power (SAE J1349/ISO 9249) 436 kW Scraper Bowl expand / collapse icon Scraper Capacity – Heaped 33.6 m³ Rated Load 47200 kg Capacity – Struck 24.5 m³ Depth of Cut – Maximum 417 mm Width – Cut – To Router Bits 3.8 m Ground Clearance – Maximum 0.7 m Hyd.

Set the desired top speed with Ground Speed Control, and the machine will find the gear that works best for the engine and the transmission, providing a lower fuel burn in speed reduced areas. The Machine Speed Limit feature replaces Top Gear Selection. Auto-Stall assists in quickly bringing the transmission to an operating temperature at start-up when working in colder climates. Cat Payload Estimator for scrapers achieves on-the-go weighing to deliver optimal payload and jobsite efficiency. WORK IN COMFORT See more 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 (optional attachment). 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 See more DESIGNED FOR SAFETY Get in and out of the cab easier with the new powered access ladder system. Enhance the operator’s awareness of site surroundings with the optional Work Area Vision System (WAVS). 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.Wide brake shoes and brake drums improve brake performance and reduce brake and drum wear Separate front and rear circuits. Secondary brakes engage automatically if service pressure drops Parking Brake features a spring-applied, hydraulic pressure released mechanism that operates the service brakes EASY TO OPERATE See more 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.
