Cool stuff. I know some Amish that still use their's to farm with. Look up Cory Anderson, the guy that built the new 150 hp Case tractor. It pulls a 62 bottom plow. Pulls 5000 lb ft on a dyno at about 300 rpms.
I have always loved these behemoths. Albany, Mn has a pioneer days event every fall that is a great show of anything farm/construction related. Nothing like standing next to a parade route with 20-30 of various makes pass you by. All the way from restored to 'barn finds' Here is a project I found a while back if anyone is interested. Sorry for the grainy pics. Didnt dare walk up the driveway.
