I would suggest your answer is in the title of your machine, the tractor unit was designed for one use, that of lawn mowing, nothing else.
Yes it will have certain power, but not the kind you are expecting, most certainly I would not stick a snow plough anywhere near it, as the chassis of the tractor is not designed for snow ploughing, you will only have to hit a raised bit of concrete under the snow and you will buckle the whole tractor
