Caterpillar 657 Tractor Scraper



657 Caterpillar scraper.

The 657 Caterpillar scraper is a combination tractor-scraper utilizing a 585-horsepower Cat C18 diesel in the tractor and a 447-horsepower C15 in the scraper. The transmission features Electronic Clutch Pressure Control, which improves shift quality and fuel efficiency. New hydraulic disc brakes improve braking performance and reduce maintenance.

The company’s largest open-bowled scraper, the Cat 657 has a heaped capacity of 44 cubic yards with a rated load of 52 tons.

The 657 Caterpillar scraper travels up to 34.8 mph and cuts to 17.3 inches with a spread depth of 25.9 inches. The new scraper is 7 percent more fuel efficient than its predecessor.

Payload Estimator provides on-the-go weighing, allowing the scraper to achieve 95 percent load accuracy, according to the company. When working in colder climates, Auto-Stall quickly brings the transmission to operating temperature at start-up. Ground Speed Control allows the operator to set the desired top speed, and the machine then finds the gear that works best for the engine and transmission.

The cab interior has 20 percent more space with visibility to the bail, cutting edge, and bowl. The air suspension comfort seat adjusts and rotates 30 degrees to reduce fatigue, and the new Advance Ride Management adjusts damping to match ground conditions. It has a power access ladder for operator safety.

High-pressure steering system requires less steering input. When in eighth gear, engine overspeed protection assists in slowing machine speed when approaching engine limits. Optional Sequence Assist automates many operator inputs each cycle to simplify machine operation.

A new hydraulic on-demand fan on the tractor increases engine fuel efficiency. The machine also has draft-arm overflow guards, which prevent material accumulation between the draft arms and bowl sides. Ground-level access for fuel fill and all daily maintenance points increases service efficiency and safety to increase machine uptime.
