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 power equipment. We design and build tools for those who prefer to do the outdoor jobs themselves. With more than 50 years of expertise, you can trust Earthquake® for your landscaping and gardening needs.

Recognizing that inflated tires can lose pressure over time and are also susceptible to punctures from unseen debris, Earthquake designers based in Cumberland, WI go to work to make a better wheel. Through the exploration of a wide variety of new designs and configurations, they distill the best features into this capable design. The tire is solid rubber and the rims are made of durable stamped steel. This wheel incorporates a very aggressive tread pattern with deep lugs that claw the ground with each revolution, and it rolls over rocks, sticks and other obstacles with ease.


Earthquake introduces its new brand look January 2018. Crowning the look is an aggressive yet elegant chrome ‘E’ Badge. In addition to this focal point, Earthquake also introduces a new family of wheels featuring five deep set spokes. Featured product touch points are now rendered in a textured bright green. Rounding out the look are black handle bars contrasting with vivid glossy red body panels.
