No it probably is 1.5 hp, they used to be sold as 5 hp before the court case. I've got a 15 year old CH one, its got more than 500 hours on it but I'm just waiting for it to go. Its loud, slow, and gets the job done. I borrow a portable usually but once in a while use this one as a big air pig. Plug it in charge it up then wheel it over to the tractor bucket.
Did I mention its ear splittingly loud?
