buying first stump grinder advice | Arboristsite
Jun 16, 2002· I don't have any personal experience with Rayco machines, but I hear they're good. My first grinder was a Dosko 691SP which I still use. I also have a Vermeer 630B, a good mid-size grinder. I agree with buying from a reputable dealer. Stump grinders generally get a lot of abuse and misuse, so buying used is sometimes a gamble.
