CAT 637K

Construction and earthmoving machines

The Caterpillar 637K is a large self propelled wheel tractor scraper used for bulk earthmoving, moving and spreading large volumes of soil over long distances in mining, road building and major site works. It sits at the heavy end of Caterpillar's scraper range, combining a powered scraper bowl with a tractor unit for efficient load, haul and dump cycles in a single machine. It is typically used where elevated production over distance is needed without separate haul trucks.

We recognise this model across the auction sites and keep every one we see together.

On a used one

Check the condition of the cutting edge, bowl floor and apron for wear, inspect the elevator and hydraulic systems for leaks, and review hours alongside engine and drivetrain service history given the heavy duty cycles these machines endure.
