In 1959, rental store employees Leo Swan and Ed Harding noted that their customers had reoccurring problems when resurfacing uneven concrete floors. At that time, the ways to level and smooth concrete surfaces were limited to one’s hands or crudely modified buffing machines. To help their customers, the budding entrepreneurs created the modern day concrete floor grinder. While this lone grinder was only intended to satisfy their current clientele, news of its existence spread, and wait times for the grinder swelled. Eventually, with this grinder as their cornerstone, Leo and Ed founded Equipment Development Company, or EDCO –a manufacturer of “Rental-Tough” products. Today, the Swan and Harding families own and operate EDCO, offering an array of products.

We moderate reviews before they're published, but we don't fact-check them
Reviews are written by equipment owners and operators. Our team looks over each review before it goes live, and anyone can report a review they think breaks the rules.
We don't verify the claims made in reviews, so each one reflects the reviewer's own experience. Some reviews may have been collected from other public sources. Brands can reply to reviews but can't edit or remove them.

Solid build, consistent results

Our old method for chasing cracks was a real bottleneck. This EDCO saw changed that. We run it daily on concrete and asphalt, and after two years, it still feels as solid as day one.

Great value for small crews

After 18 months, this EDCO saw has paid for itself easily. We considered renting or a much pricier brand, but this unit delivers.

Solid daily performer
Posted on Aug, 11 2026
For 18 months, this EDCO unit has been a daily staple. Diamond tooling wear is predictable, and fuel use is fair. Dust bags are a regular cost, but essential. Support has been responsive when needed.

High throughput, great results
Posted on Aug, 11 2026
We've run this EDCO Traffic Line Remover for over a year, often 8+ hours. It chews through old lines on asphalt and concrete fast.
