Cat® Pro Series Hydraulic Thumbs allow precise load control. They are well suited for day-in and day-out use of handling larger, longer items.

Pro Plus thumbs feature extra links to push the thumb farther, providing 100% coverage of bucket rotation.

Have full thumb control at maximum bucket and thumb extension. This also allows for greater thumb control when bucket is closer to machine and below grade.

Allows for attachment of other work tools without removing thumb (ex. Hammer). The shut-off valve also functions as a hydraulic lock when not in use.

Retractable thumb allows normal bucket loading when not in use.

Maintains rigidity while offering optimized visibility for better site into bucket when lifting irregular loads.

Optimized tine and bucket tooth spacing allows thumb and bucket to mesh together without interference. Different width buckets can be used with the same thumb for maximum flexibility.
