We moved into this current house from a development rather quickly and in the middle of winter, so I didn't have too much time to plan out my snow removal options; I knew that I would need something capable to handle keeping the driveway clear. My father in law had a tractor (Yanmar) with a front blower, so that was what streered me towards the tractor for snow removal.
I had/have a 1999 Ford Expedition, which Ford does not recommend plowing with, so that kind of put me off of getting a plow back then. If Ford said it was "okay", I probably would have done it then. However, after three years of mulling it over, I'm comfortable putting a plow on it and I've comfortable with the quality of the plow that will go on it (Snoway). The other hurdle to overcome was the cost, but, as with the tractor, the plow will pay for itself over time.
Speed and convenience are woth alot too - when coming home from work at night after it snowed during the day, I would think what a waste it was to drive up the driveway in the truck and then getting all bundled up to chug back down the driveway with the tractor with the blower.
As I mentioned before, I still want a blower as a backup in case the plow fails or we get whomped with a storm that may be too much for the plow, which is what prompted this whole "swap" idea.
