We have been plowing for many years and believe me, I HATE IT. Not the actual plowing itself but, the stress that comes with it. As far as the expense of equipment, that's minimal. I don't buy a truck just to plow. I buy a truck to work landscaping 1st, then, I look at it for snow. Extra equipment for snow are sanders, plows, and snow blowers.
Although I hate the snow business, the money is too good to give it up. What else are we going to do in the winter?
