Overview

Cat® buckets are more than just an add-on, they are an extension of your Cat machines. Each one is perfectly balanced to our excavators so you can take on heaping loads without compromising fuel efficiency or machine health. We built them to fill faster, retain your load, and fit your task.

Features At A Glance

Productivity is at its best when you pair your Cat machine with a Cat bucket, which we purpose-design to optimize the breakout force and power of the machine.
The dual radius shell profile improves material flow into the bucket. The added heel clearance ensures the bottom of the bucket does not drag, reducing maintenance costs.
Fuel consumption peaks during digging. Cat buckets are designed to cut through material quickly to enhance your machine's overall operating efficiency.
Load more material in less time. Bucket shape and sidebars keep the most material in your bucket for every load.

Count on the structural integrity of your bucket long-term. The integrated hinge plate helps distribute force better than a weld-on hinge plate
Cat buckets are manufactured with high-strength, abrasion-resistant steel, especially in excessive wear areas
Protect the high wear areas of your bucket coming into contact with materials the most with Cat Ground Engaging Tools (GET)
Get higher production in demanding applications, easier penetration into piles, and faster cycle times with Cat^® Advansys^™ GET
Install and remove tips quickly and safely with the hammerless Cat Advansys™ system while ensuring their secure fit with CapSure™ retention.
Reduce maintenance costs by selecting the right tips for your bucket and application combination, which could impact productivity.
Bucket tips are available in a variety of options such as Penetration, Penetration Plus, Heavy Duty, General Duty, Spike, Wide, and more to suit your specific application needs.
