That old Stieger looks like a mid 70's model. The steel hood was replaced by a fiberglass hood in the very late 70's. My guess is an early "couger" with an 855 Cummins under the hood. Must have a vee plow in front of course...
My neighbor has a Stieger Couger with the glass hood, a 1979 model.
They were made in Fargo ND.....Case IH bought them out in the early 80's. They still make a tractor with the name on it.
Looks like it is very capable in this some what unusual role though!!
It will last for decades as a snow plow, I would think. On a farm it would get so many more hours put on it, as many have...
Great old tractors they are!
