Our wheel tractor-scrapers have long been considered the basic method of moving volumes of material, and the Cat® 621 Wheel Tractor-Scraper is no exception. Known for its ability to be push-loaded and high travel speeds, it\u2019s always an earthmover\u2019s first tool of choice when working in challenging load areas. With an open bowl and a single engine, this machine is designed to handle a wide range of material types ranging from sand to ripped rock 609.6 mm (24 \) or less in size.

Increased Comfort

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

Improved Productivity

Improvements in fuel efficiency and responsive APECS transmission controls deliver more productivity in most applications

Additional Safety

New safety features help operators be more productive and work more efficiently all day long

EXECUTE EFFICIENCY

Advanced Productivity Electronic Control System (APECS) allows the engine and transmission to communicate on a high level. This communication allows the machine to utilize better the power and torque the engine is producing. The net result is 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 replaces Top Gear Selection.
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.
Boost productivity with the Cat Payload feature (optional attachment). Cat Payload is an automatic feature when ordered with Sequence Assist.
Cat Payload for scrapers is an earthmoving solution for optimal payload and job site 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.
