Assumptions for maximum material density rating:
1. Front Linkage fully extended at ground line
2. Machine positioned 90 degrees over the side
3. Bucket curled
4. 100% Bucket Fill Factor
Please consult with your Caterpillar dealer personnel for optimum selection of buckets and work
tools that best match your application.
*
Based on SAE J296, some calculations of capacity specs fall on borderlines. Rounding may
allow two buckets to have the same English rating, but different metric ratings.
