Note (2)
¹Cat diesel engines are required to use ULSD (ultra-low sulfur diesel fuel with 15 ppm of sulfur or less) and are compatible* with ULSD blended with the following lower-carbon intensity fuels** up to: 20% biodiesel FAME (fatty acid methyl ester)*** or 100% renewable diesel, HVO (hydrotreated vegetable oil) and GTL (gas-to-liquid) fuels. Refer to guidelines for successful application. Please consult your Cat dealer or “Caterpillar Machine Fluids Recommendations“ (SEBU6250) for details. *While Caterpillar engines are compatible with these alternative fuels, some regions may not allow their use. **Tailpipe greenhouse gas emissions from lower-carbon intensity fuels are essentially the same as traditional fuels. ***Engines with no aftertreatment devices are compatible with higher blends, up to 100% biodiesel (for use of blends higher than 20% biodiesel, consult your Cat dealer).

***Engines with no aftertreatment devices are compatible with higher blends, up to 100% biodiesel (for use of blends higher than 20% biodiesel, consult your Cat dealer).

Attachments

Tackle your jobs with a complete Cat solution. Cat attachments are not just accessories – they are essential tools that define what your machine can do. When you pair a Cat excavator with Cat attachments, you unlock a fully integrated system built for performance, durability, and efficiency. Whether you are clearing land, breaking concrete, or compacting soil, the right attachment transforms your excavator into a powerful, multi-purpose tool ready for any challenge. Depending on your project or application, you could benefit from excavator attachments such as:

        
  • Buckets: Handle everything from digging and grading to cleanup and debris removal with your excavator. Cat offers general duty, heavy duty, extreme duty, and severe duty buckets, as well as specialized designs for ditch cleaning, rock, and finishing work. Reinforced edges and wear-resistant materials ensure long-lasting performance in tough conditions.
  •     
  • Couplers: Cat couplers for excavators enable fast, secure attachment changes, without the need to leave the cab. From Pin Grabbers to hydraulic quick connect options, couplers help reduce downtime, boost jobsite efficiency and promote versatility by allowing multiple machines to share a common attachment inventory.
  •     
  • Demolition and Sorting Grapples: Tackle larger debris or precisely sort materials into piles. These grapples are engineered for accuracy in demolition and material sorting, handling concrete, rebar, wood, and mixed debris. High clamping force and agile movement make them ideal for primary and secondary demolition and recycling operations.
  •     
  • Hammers: Break concrete, rock, and steel with up to 1,000 blows per minute. Built for high-production demolition, quarrying, and construction, they offer powerful impact energy and consistent performance. Their durability and low-maintenance design make them essential for demanding breaking applications.
  •     
  • Mulchers: Ideal for forestry and agriculture applications. Mulchers clear land and manage vegetation by shredding brush, trees, and undergrowth into fine mulch. Their high-speed rotors deliver fast, consistent results, with interchangeable teeth to suit different materials and desired final mulch size.
  •     
  • Tiltrotators: Tiltrotators provide 360° rotation and 40° left/right tilt functionality, allowing attachments to move with unmatched precision and flexibility. This flexibility transforms your machine into a multi-functional tool capable of working from virtually any angle without repositioning. Ideal for grading, trenching, and complex excavation work, they deliver multi-angle control for tight and confined spaces.

Cat attachments are engineered to maximize your excavator’s productivity, helping you get more work done with greater efficiency and confidence. Choosing the right attachment is not just about compatibility, it is about unlocking your machine’s full potential while avoiding equipment damage or safety risks. Contact your Cat Dealer for a complete list of attachments available in your area to meet your specific machine and application needs.
