About Us
A History Of Innovation
It all started in 1960 in a small metal fabricating shop in Cumberland, Wisconsin. Our very first employees nurtured a culture of hard work and innovation. Through the years, we have stayed true to those values. Today, Earthquake® has grown into an international brand of purpose-built outdoor power equipment. We design and build tools for those who prefer to do the tough jobs themselves, and with more than 65 years of expertise, you can trust Earthquake® for your gardening, landscaping, and property maintenance needs.
