And, exactly how much snow can you remove with a 60+ year old CMP truck??? I would say not a whole lot compared to todays technology.
Remember, we are talking about a truck in excess of 7000lbs with a 85 HP engine. I would think it could move some, albeit very slowly. A cmp does have the gearing and torque although I think the runflat tires would be the limiting factor. Tires chains a must, otherwise she`d sit there spinning for sure.
I know our shop truck ( 1985 F150 4x4 w 351cid) has a tough time in the parking lot sometimes with 6" of heavy wet snow and ice. It features an adjustable plow and certainly has a lot more umph than a cmp... Another consideration when plowing is frame strength, as it is extremely hard on them.
I am sure at the time, something was better than nothing and we see a lot of these farmer rigs around.
