Overview
Cat® Utility Thumbs are the ideal add-on to bring a new level of versatility to your Cat machines. Designed for specific excavator and bucket combinations, they help you take on more materials without compromising fuel efficiency. We built them to be an affordable solution to handle bulky materials whenever you need.
Features At A Glance
- Cover 50% of the bucket’s rotation
- For better machine stability and load capability use a Utility Thumb, which is up to 43% lighter over Pro Series Thumbs in some size classes
- Improve visibility to the materials and in trenching applications with a narrower profile
- Increase the productivity with periodic use where a bucket or rake alone would fall short
- Works with bucket or rake to grab, pick, sort, and move materials
- Utility Thumbs are universal to across range of bucket sizes, making them easier to pair to buckets in a mixed fleet
- Secure materials between the thumb and bucket or rake with the unique curvature of the thumb and serrations on the tines
- Get the best thumb for your tasks. With two tine configurations, select the best option for a wider grip or straddling the boom during transport.
- Managing multiple attachments for a fleet is easier with a coupler system. Select thumb models are compatible with Cat Pin Grabber Couplers, allowing for machines of similar sizes to share thumbs and other attachments.
- Easily controlled from cab separate from the bucket
- Folds against machine boom for easy storage during travel or other activities
- Simple installation, maintenance, and overall operation make thumbs a simpler, more affordable owning and operating choice than grapples
