Diamond Mowers


After founding Tiger Mowers™ in 1969, Bill Doyle, Sr. sold his share to then build one of the most successful Tiger dealerships in the nation with his sons Bill Jr. and Tom. In 2000 the Doyles formed Diamond Mowers to begin manufacturing higher-quality products while delivering superior customer service.

Since its inception, Diamond Mowers has taken the mower manufacturing process to a higher level of innovative design and engineering. Unlike our competitors, Diamond is not an assembly shop. We design and manufacture our products - from the smallest parts to the largest - allowing us to control quality at every step of the process. We also offer an unprecedented 100% guarantee AND 72-hour parts shipping guarantee. And these are just some of the promises we make, and keep, to our customers.

At Diamond, we demand the best - from our products, our parts and our employees - so that you can Demand Brilliance.
