Each sharpening fixture mounts directly onto the 1″ plug of the AV-56 saddle assembly for fast setup and easy operation.

Our diamond-plated grinding wheels are precision-designed to match the factory profile of stump grinder teeth, allowing you to sharpen both the flat face and top profile to restore a like-new cutting edge. Unlike traditional green grinding wheels, Thorvie’s diamond wheels require no wheel dressing, run cleaner, and provide longer-lasting performance.
