CAT 621G

Construction and earthmoving machines

The Caterpillar 621G is a large single engine wheeled motor scraper used for bulk earthmoving, land levelling and material hauling over medium distances. It combines its own loading bowl with elevator or push loaded operation on larger sites, carrying and spreading soil in a single pass. It sits in Cat's scraper range as a mid to large capacity model, built for heavy civil construction and large scale grading work.

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

On a used one

Check the condition of the bowl, apron and ejector mechanisms for wear and hydraulic leaks, along with the cutting edge and bowl floor for excessive wear. Inspect the engine, transmission and tyres for hours worked and condition, as these scrapers typically see heavy duty cycles.
