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.
