Universal Excavator Mount

Meet the Universal Excavator Mount

The Eterra Universal Excavator Mount isn’t just another coupler — it’s a complete mounting system built to change the way operators and dealers think about excavator attachments. Designed, patented, and built right here in the USA, this system gives you true versatility across your fleet by allowing one mount to fit a wide range of excavators and work with every Eterra attachment that uses our Universal Rail Mount System.

Here’s how it works: the base plate of the mount fits excavators with 30–50mm pins, and uses adjustable eccentric collars to fine-tune your pin spacing within 10mm. That means you can dial in the perfect OEM fit, not just get “close enough.” On top of that, stackable spacers let you adjust the inner width of the mount to match your machine’s factory tolerances, keeping the attachment perfectly centered and tight. The result is a mount that performs like it was made for your machine — because it essentially is, every time you adjust it.

Built from 3/8” thick steel, reinforced in all the right places, and equipped with hardened, greasable pins, this mount is engineered to last longer than the machines it’s used on. Every detail serves a purpose: greasable bolt pins prevent seizing and extend lifespan, while hardened components handle the abuse of high-impact attachments without deforming or wearing down. And when you eventually move to a new excavator, you don’t need to buy another mount — just adjust this one.

This is the only excavator mount in the world built to stay with you through multiple machines, multiple attachments, and countless jobs. It’s battle-tested to Eterra standards, which means the mount will outlast the machine. Dealers can confidently stock one mount that covers multiple models and sizes, and operators can finally invest in a system designed to evolve with their equipment.
