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 optimized K Series linkage 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.
