Bucket Specifications and Compatibility
Caterpillar recommends using appropriate work tools to maximize the value customers receive from our products .
Use of work tools, including buckets, which are outside of Caterpillar’s recommendations or specifications for
weight, dimensions, flows, pressures, etc . may result in less-than-optimal performance, including but not limited
to reductions in production, stability, reliability, and component durability . Improper use of a work tool resulting in
sweeping, prying, twisting and/or catching of heavy loads will reduce the life of the boom and stick.
