The grinding head is now completely sealed and dust proof for longer service life and less maintenance. A redesigned chain driven planetary drive, new stronger timing belt, upgraded shafts and pulleys are just some of the changes that have been designed to take these grinders to the next level of operability and reliability. The new frame design with upgraded weights and handle allow for better control, easier tool changes, and less vibrations. The first S7 machines, 25” and 30” propane and electric models, will be available in the 2nd quarter of 2023, with more sizes to follow later in the year.
