I have a 400ft gravel driveway that I have been plowing with an old
garden tractor and a 48" plow. It takes a while and traction is often
an issue going up hill, but I can get it done with chains and wheel
weights.

I have seen these lightweight personal plows like Snowbear that are
almost 7ft and can bolt on to a truck and be removed easily. The are
raise with an electric winch, and you have to get out of the truck to
angle the blade manually (not an issue since I have to do the same
thing with the tractor blade...and i'm outside all the time then).

I have an older F150 4x4 that is in great shape and would use that to
plow. Anyone have an experience with these? It would only be for my
driveway, but I don't want to buy something that will only last a year
or two.
