Allis Chalmers HD20 Snow Plowing

Yair...I thought this may have been of interest. I have'nt seen this clip before. I recall seeing one of those elevators throwing up a road formation when I was a kid. Would any one have details...they look pretty darn efficient. Cheers.

Discuss this in the forum topic How it used to be done...tractor towed elevators on Garison Dam..
