Been using Dad's old concrete mixer, but the motor died on it YEARS ago....<br /><br />He put a pully and a PTO Shaft to run it off a tractor. Have a few projects at the house, but don't want to have to borrow my brothers tractor every time I want to use the mixer.<br /><br />What size motor should I be looking for?<br />1/2 hp enough?<br /><br />This thing is geared way down, I wouldn't think it would take much to turn it
