Fully hydraulic water well drill. It is fully self contained, is powered by a 15.8hp motor. It uses 10 sticks of drill rod and comes with a 2 trash pump and 150 of rod. There are two drill bits, a 6 3/4 tungsten carbide bit, and a 6 3/4 pdc button tip bit. It has served its purpose well for me but was always intended to be used then passed on
