Delivering efficiency through technology along with unparalleled strength, power and durability, the Cat® 637K wheel-tractor scraper provides an industry-leading performance across even the most difficult conditions and materials on sites around the world. This best-in-class Cat wheel-tractor scraper is feature packed, and as a Cat machine, it prioritises operator comfort and safety in addition to performance and reliability to deliver a machine that you can rely on to keep your projects on track and budget, and boost your business bottom line. 

The tractor of the Cat 637K is powered by a Cat C18 engine with MEUI™ and 8-speed planetary powershift transmission while a Cat C9.3 engine and 4-speed planetary powershift transmission powers its scraper. While an extremely powerful machine, operator comfort and control have been prioritised with the 637K, with the new K Series steering system requiring significantly less steering effort than its predecessor, resulting in decreased operator fatigue that can potentially enable higher production rates. Additionally, the K Series cab has a 21% larger interior than the G Series cab, delivering improved operator visibility and comfort that not only benefits your operators but everyone on site. 

Safety is at the forefront of the features the 637 scraper boasts, with innovations like Tire Spin Reduction that allows operators to isolate the slip of the tyres and Differential Lock Engagement Protection which allows the machine to prevent the operator from engaging the differential lock when damage could potentially occur. Another important feature with this wheel-tractor scraper is the automatically-engaging brakes that enable the machine to determine over speed conditions based on acceleration rates and automatically apply the brakes.
