My father is a water well driller. His number one rig is a Bucyrus Erie "20-W" cable tool rig that is mounted on a Chevy cab & chassis. It originally was mounted to an old international loadstar, but that was eventually upgraded to the Chevy C60. We also changed out the tired old 4 cylinder Allis-Chalmers power unit to a 3 cylinder diesel.
His second rig was a Keystone 50 mounted on a 1971 International loadstar with a 5+2 speed transmission. The Keystone was powered by a 4 cylinder gasoline powerplant. We have since sold this machine to a fellow in Missouri.
