John pointed this out. It includes a video.
“A rare, working, 1952 Willys Jeep CJ2A with an Auburn Jeep-A-Trench trencher. It will dig a trench 6″ wide and 46″ maximum depth. The trencher was made in Auburn, Nebraska by a company that is still in existence today. I have used this trencher 3-4 times a year for the past 6 years. It has been kept in a barn, each time I just put battery in it and it is ready to go. I have used it for installing water lines, electrical lines, drainage tile and rain water downspouts. It was previously owned by a local plumber. It is simple to use and once digging is started you just stand back and watch it work. It runs great and has not overheated in our hot and humid Kansas summers. Brakes are soft and steering is stiff but you’re really not going to drive it any distance anyway. It is self propelled via creeper gears and the digging outrigger can be raised and lowered via an electric motor. All of the standard Jeep CJ2A features are still retained. It was converted to 12 volt then the trencher unit was added at the factory along with a Governor to regulate engine speed, a PTO unit, an additional drive shaft, heavy springs and frame stiffeners. Exact mileage unknown, but it can’t be to high because the trencher has been on it since day one. Comes with spare parts including extra trencher teeth and chain links and owner guide. Have a clear title. Sold AS IS, no warranty. Also for sale locally. I will not deliver. If you arrange shipping I will assist with loading.
