Bucket Fill Factors
Fill Factor is the percentage of an available volume in a hauler body, bucket or bowl that is actually used.
For example, a fill factor of 87 percent for a hauler body means that 13 percent of the rated volume is not being used to carry material. Buckets often have fill factors over 100 percent.

Notes
- Loader bucket fill factors are affected by bucket penetration, breakout force, rack back angle, bucket profile and ground engaging tools such as bucket teeth of bolt-on replaceable cutting edges.
- For bucket fill factors for hydraulic excavators, see bucket payloads in the hydraulic excavator section.
- Above values are not valid for Hydraulic Mining Shovels.
Additional materials can be found in the Caterpillar Performance Handbook. Consult your Cat dealer for more information.
