Pushed a lot of snow with my 1945 allis Chalmers WD45. Do all loader, PTO driven pump, fluid in the back tires.
I graduated to pickup truck snow plowing many years ago though, no regrets.
I don't miss plugging in the tank style coolant circulating heater, cranking the old engine, letting the stiff hydrolics warm up, sitting on that metal seat...
It worked, but I don't miss it.
