Wasn't sure where to post this unusual piece of equipment so...
Made by General in the 60s. Powered by a 20hp Onan CCK engine.
Factory custom trailer.
Steers like a skid steer using hydraulic motors with roller chains to the wheels.
It did come with 2 auger bits. Both were worn down into a cone shape and would only dig about 2 feet and bind up. So I cut off both ends and swapped them around which made all the difference. Pic is before they were cut and welded.
