Material density and fill factor are key variables when choosing the appropriate size of the bucket.The long floor and open throat design of the Performance Series Buckets along with the aggressive rack angles of the Cat Optimized Z-bar Loader will demonstrate fill factors greater than 100% ISO rated. Refer to the Fill Factors table for expected fill factor per material density and Bucket Selection table for bucket sizing.
