The DC was never noted as great plow tractor. It pulled 3 bottoms in the clay ground of south eastern Ill.
But a DC was mean machine with a wheel disk. It was pulling machine.
The Case hydraulics were primitive so it could not pull the plow out of the ground when the conditions go bad like a ford.
Case made equipment that would pull and if the tractor could not pull the load it would spin the tires and dig a hole.
They were great machines.
