Product information

Description

The Cat 388-9664 is a 47-inch pin-on grading bucket for compatible Cat mini hydraulic excavators. Its wide, toothless profile is designed for ditch cleaning, slope cutting, grading and finishing work where a smoother surface matters.

A bolt-on cutting edge supports clean grading, while the bucket's nesting design makes it easier to transport additional buckets to the jobsite. Confirm carrier model and pin-on interface compatibility before ordering.

We are very pleased with our purchase! The machine was fully assembled. We have already used it to build ponds and dig ditches, and it is working well.

Ethan Harmon with delivered compact equipment

Ethan Harmon, Chicago

This machine provides excellent stability for its compact size. Despite its compact size, the stability on this machine is excellent, especially when the tracks are fully extended.

Received a high-quality product 7 hours before the promised time. I used it immediately and drilled 28 holes with no issues.
