It only has a 4 hp motor ,at the time I questioned the Agazzani dealer about it and he said that with the heavy wheels once in motion that they need very little HP to keep them turning he said it's the same saw the Smithsonian & some top notch furniture makers use ,I was skeptical but he was right when I shut it off the wheels will keep spinning for 4 minutes if I don't touch the brake, I have cut some big logs with it and it never bogs down it has been a great saw for me ,I bought it with the intention that I would never need another !
